Welcome to Astronomy Daily, your friendly and engaging guide to the cosmos. I'm your host, Anna, and I'm thrilled to bring you the latest and most exciting news from the world of space and astronomy. Today, we'll discuss Russia's ambitious plans for a new space station, uncover interstellar objects with the Vera C. Rubin Observatory, explore fascinating connections between supermassive black holes and dark matter, and take a look at space tourism reviews on TripAdvisor. So fasten your seatbelts and get ready for a cosmic journey through today's top stories.Russia's New Space Station: ROSS: Russia's space agency Roscosmos has unveiled an ambitious plan for its newest space station, the Russian Orbital Service Station (Ross). The first module is expected to launch by 2027, marking a significant step forward for Russia's space exploration efforts. Ross will orbit at the same altitude as the International Space Station but aims to foster new partnerships with countries like Brazil, India, China, and South Africa. The project, estimated to cost around $7 billion USD, will integrate artificial intelligence into its operations and assist in guiding a fleet of satellites, presenting novel challenges for mission control.- Vera C. Rubin Observatory's Legacy Survey: The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) is set to revolutionize our understanding of interstellar objects and planetary formation. Starting in 2025, this survey will leverage cutting-edge technology to detect smaller, fainter interstellar objects with unprecedented precision. Scientists are optimistic that Rubin's powerful capabilities will reveal dozens, if not hundreds, of new interstellar objects, providing valuable data about the formation and evolution of distant planetary systems.- Supermassive Black Holes and Dark Matter: Astrophysicists have uncovered a remarkable link between supermassive black holes and dark matter particles, shedding new light on the longstanding final parsec problem. Researchers propose that dark matter particles interact in ways previously overlooked, helping supermassive black holes bridge the final parsec and merge. This discovery not only solves the final parsec problem but also aligns with the recent background hum of gravitational waves detected, offering a new window into the microphysics of dark matter.- Space Tourism Reviews on TripAdvisor: TripAdvisor is now featuring reviews of space tourism experiences, offering insights into the burgeoning industry. Potential travelers can read firsthand accounts of zero gravity flights and orbital journeys, helping them choose their next cosmic vacation. Whether considering a suborbital trip with SpaceX or a stay at a commercial space station, these reviews provide valuable information for planning an out-of-this-world adventure.Don't forget to visit our website at astronomydaily.io where you can sign up for our free daily newsletter and stay updated with the latest space news via our constantly updating news feed.

On a mountain top in the foothills of the Andes in northern Chile a new kind telescope, the LSST, is under construction. It's unique design allows it to image an area of the sky 40 times the size of the full moon and thus record the entire sky twice a week. In 30 seconds the LSST can spot objects 10 million times fainter than we can see with our eyes. It will discover objects which change in brightness and position to enable astronomers to study dark energy, weird stars, Earth approaching objects, and other fascinating time dependent events in the Universe.

"Exploring the Outer Edges of the Solar System" So, you're probably wondering about what's out there, right at the edge of our very own Solar System? Well, it's truly a fascinating realm that's still full of mysteries and discoveries to be made. This uncharted frontier, deemed as the 'outer edges', is largely dominated by frozen volatile substances like water, methane, and ammonia. These celestial bodies, often referred to as Trans-Neptunian Objects (TNOs), are believed to have remained untouched since the beginning of our Solar System, making them incredibly valuable to astronomers as they piece together the cosmic puzzle. Now, Andrew Dunkley delves into this very topic during the podcast. His curious mind bubbles over with questions and musings, all tinged with a sense of awe and wonder for the unknown. He draws attention to the curious alignment of some TNOs - suggestive of a possible unseen planetary body nicknamed 'Planet Nine.' Despite the inconclusive evidence and difficult prospect of direct observation, Andrew's excitement is infectious, igniting a curiosity that makes even the farthest reaches of our Solar System seem tantalizingly within reach. "Emission Lines and Spectroscopy" Ever gazed at a sodium vapor streetlight and wondered why it shines so orange? Or pondered why certain colors 'pop' in the spectrum of a star? The concept of emission lines and spectroscopy has the answers. This field of astrophysics uses the spectral properties of light to determine the chemical composition and physical properties of celestial objects. It's a bit like unlocking the star's 'identity card' through the visible and invisible light it emits. Not only does this add an analytical edge to stargazing, but it also provides fundamental insights into the universe's anatomy. To provide a tangible context, Andrew Dunkley uses the example of sodium vapor streetlights, whose characteristic orange comes from the photon of light emitted by excited sodium atoms. Andrew navigates this complex topic with crystal-clear analogies, making it both comprehensible and captivating. His conversation dives into the sun's behavior, touching upon its photosphere, chromosphere, and even the enigmatic concept of black bodies. By weaving these threads together, Andrew masterfully brings out the intensely scientific yet genuinely stunning aspect of our cosmos. "The Search for Planet Nine" 'Hypothetical' might be the operative word when we talk about 'Planet Nine', but don't let that dull your curiosity. This proposed super-Earth, lurking at the outskirts of our solar system, has got scientists and space enthusiasts on the edge of their seats. It's essentially a cosmic 'Whodunit?,' propelled by unusual TNO alignments and the enduring allure of the unknown. From gravitational tugs to cosmic dances, all threads seem to point towards a master puppeteer, an unseen force – one that fits the billing of a rogue Planet Nine. During the podcast, Andrew Dunkley's take on Planet Nine is much akin to a thrilling treasure hunt. He dives into the resilient hypothesis, the indicative TNO alignments, and the potential game-changing role of the upcoming Vera Rubin Telescope in this quest. The pursuit of Planet Nine, as Andrew explains, is not just about satisfying curiosity; capturing it could drastically alter our understanding of the solar system's architecture and dynamics. He undoubtedly leaves us yearning for more discoveries and eager to join the cosmic manhunt.For more Space Nuts visit www.spacenuts.io

Satellite Constellation Avoidance with the Rubin Observatory Legacy Survey of Space and Time by Jinghan Alina Hu et al. on Wednesday 30 November We investigate a novel satellite avoidance strategy to mitigate the impact of large commercial satellite constellations in low-Earth orbit on the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). We simulate the orbits of currently planned Starlink and OneWeb constellations ($sim$40,000 satellites) to test how effectively an upgraded Rubin scheduler algorithm can avoid them, and assess how the overall survey is affected. Given a reasonably accurate satellite orbit forecast, we find it is possible to adjust the scheduler algorithm to effectively avoid some satellites. Overall, sacrificing 10% of LSST observing time to avoid satellites reduces the fraction of LSST visits with streaks by a factor of two. Whether such a mitigation will be required depends on the overall impact of streaks on science, which is not yet well quantified. This is due to a lack of adequate information about satellite brightness distributions as well as the impact of glints and low surface brightness residuals on alert purity and systematic errors in cosmological parameter estimation. A significant increase in the number of satellites or their brightness during Rubin Operations may make implementing this satellite avoidance strategy worthwhile. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.15908v1

Using Host Galaxy Photometric Redshifts to Improve Cosmological Constraints with Type Ia Supernova in the LSST Era by Ayan Mitra et al. on Monday 17 October We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using only the "zspec" subset with spectroscopic redshifts from the host or SN. We use the Deep Drilling Fields (~50 deg^2) from the Photometric LSST Astronomical Time-Series Classification Challenge (PLaSTiCC), in combination with a low-z sample based on Data Challenge2 (DC2). The analysis includes light curve fitting to standardize the SN brightness, a high-statistics simulation to obtain a bias-corrected Hubble diagram, a statistical+systematics covariance matrix including calibration and photo-z uncertainties, and cosmology fitting with a prior from the cosmic microwave background. Compared to using the zspec subset, including events with SN+host photo-z results in i) more precise distances for z>0.5, ii) a Hubble diagram that extends 0.3 further in redshift, and iii) a 50 % increase in the Dark Energy Task Force figure of merit (FoM) based on the w0-wa CDM model.

Harnessing Unresolved Lensed Quasars: The Mathematical Foundation of the Fluctuation Curves by Satadru Bag et al. on Sunday 25 September Strong gravitational lensed quasars (QSOs) have emerged as powerful and novel cosmic probes as they can deliver crucial cosmological information, such as a measurement of the Hubble constant, independent of other probes. Although the upcoming LSST survey is expected to discover $10^3-10^4$ lensed QSOs, a large fraction will remain unresolved due to seeing. The stochastic nature of the quasar intrinsic flux makes it challenging to identify lensed ones and measure the time delays using unresolved light curve data only. In this regard, Bag et al (2022) introduced a data-driven technique based on the minimization of the fluctuation in the reconstructed image light curves. In this article, we delve deeper into the mathematical foundation of this approach. We show that the lensing signal in the fluctuation curve is dominated by the auto-correlation function (ACF) of the derivative of the joint light curve. This explains why the fluctuation curve enables the detection of the lensed QSOs only using the joint light curve, without making assumptions about QSO flux variability, nor requiring any additional information. We show that the ACF of the derivative of the joint light curve is more reliable than the ACF of the joint light curve itself because intrinsic quasar flux variability shows significant auto-correlation up to a few hundred days (as they follow a red power spectrum). In addition, we show that the minimization of fluctuation approach provides even better precision and recall as compared to the ACF of the derivative of the joint light curve when the data have significant observational noise. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.11078v1

The PAU Survey & Euclid: Improving broad-band photometric redshifts with multi-task learning by L. Cabayol et al. on Wednesday 21 September Current and future imaging surveys require photometric redshifts (photo-z) to be estimated for millions of galaxies. Improving the photo-z quality is a major challenge to advance our understanding of cosmology. In this paper, we explore how the synergies between narrow-band photometric data and large imaging surveys can be exploited to improve broad-band photometric redshifts. We use a multi-task learning (MTL) network to improve broad-band photo-z estimates by simultaneously predicting the broad-band photo-z and the narrow-band photometry from the broad-band photometry. The narrow-band photometry is only required in the training field, which enables better photo-z predictions also for the galaxies without narrow-band photometry in the wide field. This technique is tested with data from the Physics of the Accelerating Universe Survey (PAUS) in the COSMOS field. We find that the method predicts photo-z that are 14% more precise down to magnitude i_AB1. Applying this technique to deeper samples is crucial for future surveys like Euclid or LSST. For simulated data, training on a sample with i_AB

A Joint Roman Space Telescope and Rubin Observatory Synthetic Wide-Field Imaging Survey by M. A. Troxel et al. on Thursday 15 September We present and validate 20 deg$^2$ of overlapping synthetic imaging surveys representing the full depth of the Nancy Grace Roman Space Telescope High-Latitude Imaging Survey (HLIS) and five years of observations of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). The two synthetic surveys are summarized, with reference to the existing 300 deg$^2$ of LSST simulated imaging produced as part of Dark Energy Science Collaboration (DESC) Data Challenge 2 (DC2). Both synthetic surveys observe the same simulated DESC DC2 universe. For the synthetic Roman survey, we simulate for the first time fully chromatic images along with the detailed physics of the Sensor Chip Assemblies derived from lab measurements using the flight detectors. The simulated imaging and resulting pixel-level measurements of photometric properties of objects span a wavelength range of $sim$0.3 to 2.0 $mu$m. We also describe updates to the Roman simulation pipeline, changes in how astrophysical objects are simulated relative to the original DC2 simulations, and the resulting simulated Roman data products. We use these simulations to explore the relative fraction of unrecognized blends in LSST images, finding that 20-30% of objects identified in LSST images with $i$-band magnitudes brighter than 25 can be identified as multiple objects in Roman images. These simulations provide a unique testing ground for the development and validation of joint pixel-level analysis techniques of ground- and space-based imaging data sets in the second half of the 2020s -- in particular the case of joint Roman--LSST analyses. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.06829v1

What could KIDSpec, a new MKID spectrograph, do on the ELT? by V. Benedict Hofmann et al. on Monday 12 September Microwave Kinetic Inductance Detectors (MKIDs) are beginning to become more prominent in astronomical instrumentation, due to their sensitivity, low noise, high pixel count for superconducting detectors, and inherent energy and time resolving capability. The Kinetic Inductance Detector Spectrometer (KIDSpec) will take advantage of these features, KIDSpec is a medium resolution MKID spectrograph for the optical/near infrared. KIDSpec will contribute to many science areas particularly those involving short and/or faint observations. When short period binary systems are found, typical CCD detectors will struggle to characterise these systems due to the very short exposures required, causing errors as large as the estimated parameter itself. The KIDSpec Simulator (KSIM) has been developed to investigate how much KIDSpec could improve on this. KIDSpec was simulated on an ELT class telescope to find the extent of its potential, and it was found that KIDSpec could observe a $m_{V}approx{24}$ with an SNR of 5 for a 10s exposure at 1420 spectral resolution. This would mean that KIDSpec on an ELT class telescope could spectroscopically follow up on any LSST photometric discoveries of LISA verification sources. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.05144v1

Classifying Astronomical Transients Using Only Host Galaxy Photometry by Marina Kisley et al. on Sunday 11 September The Legacy Survey of Space and Time (LSST) at the Vera C. Rubin Observatory will discover tens of thousands of extragalactic transients each night. The high volume of alerts demands immediate classification of transient types in order to prioritize observational follow-ups before events fade away. We use host galaxy features to classify transients, thereby providing classification upon discovery. In contrast to past work that focused on distinguishing Type Ia and core-collapse supernovae (SNe) using host galaxy features that are not always accessible (e.g., morphology), we determine the relative likelihood across $12$ transient classes based on only 19 host apparent magnitudes and colors from $10$ optical and IR photometric bands. We develop both binary and multiclass classifiers, using kernel density estimation to estimate the underlying distribution of host galaxy properties for each transient class. Even in this pilot study, and ignoring relative differences in transient class frequencies, we distinguish eight transient classes at purities significantly above the 8.3% baseline (based on a classifier that assigns labels uniformly and at random): tidal disruption events ($48%pm27%$, where $pm$ indicates the 95% confidence limit), SNe Ia-91bg ($32%pm18%$), SNe Ia-91T ($23%pm11%$), SNe Ib ($23%pm13%$), SNe II ($17%pm2%$), SNe IIn ($17%pm6%$), SNe II P ($16%pm4%$), and SNe Ia ($10%pm1%$). We demonstrate that our model is applicable to LSST and estimate that our approach may accurately classify 59% of LSST alerts expected each year for SNe Ia, Ia-91bg, II, Ibc, SLSN-I, and tidal disruption events. Our code and dataset are publically available. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.02784v2

Forward-modelling the Luminosity, Distance, and Size distributions of the Milky Way Satellites by Viraj Manwadkar et al. on Sunday 11 September We use texttt{GRUMPY}, a simple regulator-type model for dwarf galaxy formation and evolution, to forward model the dwarf galaxy satellite population of the Milky Way (MW) using the Caterpillar zoom-in simulation suite.

Classifying Astronomical Transients Using Only Host Galaxy Photometry by Marina Kisley et al. on Sunday 11 September The Legacy Survey of Space and Time (LSST) at the Vera C. Rubin Observatory will discover tens of thousands of extragalactic transients each night. The high volume of alerts demands immediate classification of transient types in order to prioritize observational follow-ups before events fade away. We use host galaxy features to classify transients, thereby providing classification upon discovery. In contrast to past work that focused on distinguishing Type Ia and core-collapse supernovae (SNe) using host galaxy features that are not always accessible (e.g., morphology), we determine the relative likelihood across $12$ transient classes based on only 19 host apparent magnitudes and colors from $10$ optical and IR photometric bands. We develop both binary and multiclass classifiers, using kernel density estimation to estimate the underlying distribution of host galaxy properties for each transient class. Even in this pilot study, and ignoring relative differences in transient class frequencies, we distinguish eight transient classes at purities significantly above the 8.3% baseline (based on a classifier that assigns labels uniformly and at random): tidal disruption events ($48%pm27%$, where $pm$ indicates the 95% confidence limit), SNe Ia-91bg ($32%pm18%$), SNe Ia-91T ($23%pm11%$), SNe Ib ($23%pm13%$), SNe II ($17%pm2%$), SNe IIn ($17%pm6%$), SNe II P ($16%pm4%$), and SNe Ia ($10%pm1%$). We demonstrate that our model is applicable to LSST and estimate that our approach may accurately classify 59% of LSST alerts expected each year for SNe Ia, Ia-91bg, II, Ibc, SLSN-I, and tidal disruption events.

Cosmological model-independent measurement of cosmic curvature using distance sum rule with the help of gravitational waves by Yan-Jin Wang et al. on Tuesday 06 September Although the cosmic curvature has been tightly constrained in the standard cosmological model using observations of cosmic microwave background anisotropies, it is still of great importance to independently measure this key parameter using only late-universe observations in a cosmological model-independent way. The distance sum rule in strong gravitational lensing (SGL) provides such a way, provided that the three distances in the sum rule can be calibrated by other observations. In this paper, we propose that gravitational waves (GWs) can be used to provide the distance calibration in the SGL method, which can avoid the dependence on distance ladder and cover a wider redshift range. Using the simulated GW standard siren observation by the Einstein Telescope as an example, we show that this scheme is feasible and advantageous. We find that $DeltaOmega_ksimeq 0.17$ with the current SGL data, which is slightly more precise than the case of using SN to calibrate. Furthermore, we consider the forthcoming LSST survey that is expected to observe many SGL systems, and we find that about $10^4$ SGL data could provide the precise measurement of $DeltaOmega_ksimeq 10^{-2}$ with the help of GWs. In addition, our results confirm that this method of constraining $Omega_k$ is strongly dependent on lens models. However, obtaining a more accurate phenomenological model for lens galaxies is highly predictable as future massive surveys observe more and more SGL samples, which will significantly improve the constraint of cosmic curvature. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2201.12553v2

The Vera Rubin Observatory will house a survey telescope that will image the night sky faster and deeper than ever before. Its camera, at 3.6 Gigapixels, will be the biggest digital camera ever built. The Rubin Observatory will be able to image the entire visible sky every few nights, and build up, over 10 years, a 900-frame full color movie of the deep night sky. This will enable a wide variety of scientific explorations, from the outer reaches of our Solar System, through our Milky Way Galaxy and its dark matter halo, and out into the extra-galactic universe, where we hope to see new types of cosmic explosions and the weird effects of the mysterious Dark Energy.  Dr. Phil Marshall (of Stanford University) gives a guided tour of the  Observatory, describes the planned sky survey, discusess the challenges of doing astronomy at petabyte scale, and shows how we can all take part in Rubin's voyage of discovery.

#64 Disputa pelo céu - Como as redes de satélites privados tem interferido nas observações de astrônomos

A SpaceX, empresa do bilionário Elon Musk, completou a marca de 800 satélites em órbita da Terra. Eles fazem parte da rede StarLink, que vai vender acesso à internet. Apesar dos resultados promissores, a ideia de uma constelação de satélites é bastante polêmica. Astrônomos utilizam o céu noturno para observar estrelas, planetas e galáxias. Quando a primeira fase da Starlink foi lançada, a visão dos pesquisadores ficou prejudicada em alguns pontos. Em uma carta oficial à Comissão Federal de Comunicações dos Estados Unidos (FCC, na sigla em inglês), a Nasa manifestou preocupação com as novas constelações de satélites. A agência espacial norte-americana acredita que o plano de órbita dos satélites apresenta risco de colisão. isto nas próximas décadas, pode representar um grande problema. Recentemente, a Estação Espacial Internacional teve de realizar manobras para evitar colisões potenciais com detritos espaciais. Esta nova onda de satélites tem a ver com a alta velocidade de conexão com a internet. Em vez de serem limitados por fios e cabos, os satélites podem transferir o acesso à internet do espaço para o chão. E se houver muitos deles em órbita, significa que mesmo as regiões mais remotas do planeta podem obter conectividade. Atualmente existem cerca de três mil satélites ativos trafegando ao redor da Terra. Com a iniciativa da StarLink e outras empresas, essa frota deve pular para 12 mil nos próximos anos. A empresa britânica OneWeb está produzindo cerca de 650 satélites, mas esse número pode aumentar para 2.000 se houver demanda maior por parte dos clientes. Já a gigante Amazon tem uma constelação de 3.200 naves espaciais planejada. A maioria dos satélites está em órbitas abaixo de 500 km de distância da Terra. Mas os astronautas ficaram preocupados quando a sonda apareceu como flashes brancos brilhantes em suas imagens de observação do espaço. Cientistas acreditam que os satélites podem ter um impacto real nas observações do espaço. Eles estão em primeiro plano entre o que estamos observando da Terra e o resto do universo. Com isso, cientistas podem deixar de ver o que está por trás desses satélites, seja um asteroide potencialmente perigoso perto da Terra ou o Quasar mais distante no universo. Vários astrônomos afirmam que seria particularmente problemático para os telescópios realizarem grandes pesquisas no céu, como o futuro Grande Telescópio de Pesquisa Sinóptica (LSST) no Chile. Segundo porta-vozes da SpaceX, a empresa está trabalhando ativamente com astrônomos internacionais para minimizar o impacto dos satélites Starlink. Já a OneWeb afirmou que será "líder de projetos no espaço responsável" e pretende colocar seus satélites em uma órbita de 1.200 km, para não interferir nas observações astronômicas. Por enquanto, essa disputa pelos céus ainda está em aberto, mas ela é muito importante e vai repercutir na vida de todos nós.

We chatted about how Mario was inspired to become an astronomer, and one notable name came up: James T. Kirk. That’s all it took. Oh, and also Isaac Asimov and Arthur C. Clarke. Most of the show, however, centered around two things: mapping our Milky Way galaxy and and his work on the Vera C. Rubin Observatory project, previously the LSST. Starting in 2021, this telescope will capture panoramic images of the entire visible sky twice each week for 10 years, building up our deepest, widest, image of the universe. The result: hundreds of petabytes of imaging data for close to 40 billion objects. One mission: planetary defense!

First discovered in 2007 at Australia's Parkes radio telescope, FRBs are very brief, very bright single radio pulses that can last for several milliseconds. It's estimated that several thousand per day are occurring over the entire sky. The most famous one is FRB 121102, unusual because it's been detected a few hundred times since it first “burst” onto the scene in 2014. FRB 121102 is coming from a small dwarf galaxy about three billion light-years from Earth. Well, it's not black holes, according to Dr. Shivani Bhandari, an astronomer with CSIRO, Australia's national science agency, whose new research published this week in The Astrophysical Journal Letters reveals that four FRBs are coming not from the heart of galaxies, but from their edge. “These precisely localised fast radio bursts came from the outskirts of their home galaxies, removing the possibility that they have anything to do with supermassive black holes,” said Dr. Bhandari. Her team found the exact location of four new fast radio bursts—FRB 180924, FRB 181112, FRB 190102 and FRB 190608—by zooming-in on the radio sky using a detector on the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope in outback Western Australia. The findings brings astronomers a step closer to understanding the origins of these mysterious signals from outer space. China outlines ambitious plan to build space station in orbit Link: https://www.axios.com/china-space-station-56b71c1e-a6f6-4c69-b74e-2975f3e335d1.html China has an ambitious new plan to build a space station in orbit by 2023. Why it matters: The U.S. sees China as a rival in space, so any large undertaking like this one will be watched closely. The space station also represents the evolution of China's space program, which made use of two smaller test stations in orbit that hosted crew before moving on to this more complex design. Details: China plans to launch the first module of its new space station next year, with a total of 11 launches needed to complete the station by 2023, according to a report from SpaceNews. The station is expected to eventually play host to crews of three astronauts aboard for six months who can perform experiments and other activities from orbit. It's also possible the crewed SpaceX launch could influence the burgeoning commercial space sector in China, according to Cheng. "The Chinese are worried, not about Elon Musk per se, but they recognize that companies can do entrepreneurship way better than state-owned enterprises," Cheng said. Is ‘Planet Nine' Actually A Black Hole In The Solar System? There's Only One Way To Find Out Link: https://www.forbes.com/sites/jamiecartereurope/2020/06/03/is-planet-nine-actually-a-black-hole-in-the-solar-system-theres-only-one-way-to-find-out/#1ef87517ef40 Planet Nine is hypothesized to follow an elliptical orbit around the Sun. It would take the planet between 10,000 and 20,000 years to make one full orbit around the Sun. The planet is estimated to have 5 to 10 times the mass of Earth and a radius of 2 to 4 times Earth's. Is there a “Planet Nine” lurking at the fringes of the solar system? Or could it be something a whole lot more scary—a primordial black hole? A new paper by Harvard University undergraduate Amir Siraj and theoretical astrophysicist Avi Loeb (he Mysterious Interstellar Object ‘Oumuamua) suggests that a new telescope currently being constructed in Chile could hold the key to discovering whether there is, in fact, a black hole located in our own solar system. Why do some think that Planet Nine could be a black hole? “Planet Nine” being a black hole is very unlikely, but no more so than “Planet Nine” existing at all, according to Siraj and Loeb. “If it exists and is not a statistical fluke, ‘Planet Nine' is most likely a planet, not a black hole,” said lead author Siraj in an email to me last week. “There is no unambiguous evidence showing that black holes exist that are less massive than the about mass of the Sun.” However, another recent paper showed that the probability of the solar system capturing a free-floating planet at the distance of Planet Nine could be comparable to the probability of gravitationally capturing a black hole with a similar mass. What is the Rubin Observatory? The paper suggests that the Rubin Observatory—which is now in an advanced state of construction close to the Gemini South telescope—will be able to confirm the existence, or not, of a black hole in the solar system. The Rubin Observatory is all about wide-angle, real-time astronomy. Its 10-year “Legacy Survey of Space and Time” (LSST) survey of the sky will image the entire southern hemisphere night sky every three nights, with each image covering an area 40 times the size of the full Moon. How to find black hole in the solar system “The LSST will be unique in its ability to survey the entire sky about twice per week at a remarkable level of sensitivity,” said Siraj. “We calculated that the flares from the accretion of a small body onto a ‘Planet Nine' black hole would be brightest near the optical band, where LSST operates.” However, there is one small problem with hunting a black hole. SpaceX Starlink and other upcoming mega-constellations of satellites are said to be particularly problematic for the Rubin Observatory's plans to survey the night sky.

Anais is currently based in France and is part of the team who are the science drivers of the Dark Energy Science Collaboration attached to the LSST (the Large Synoptic Survey Telescope) which is under construction at Cerro Pachón on the Andes Mountains of Northern Chile. For observers and astrophotographers, in ‘What’s Up Doc’, Dr Ian ‘Astroblog’ Musgrave tells us what to look out for in the morning and evening skies. In the News: .1. Press release from the University of Bath, UK Published yesterday on Wednesday 19 June 2019 “Astronomers make first detection of polarized radio waves in Gamma Ray Burst jets” Good fortune and cutting-edge scientific equipment have allowed scientists to observe a Gamma Ray Burst jet with a radio telescope and detect the polarisation of radio waves within it for the first time - moving us closer to an understanding of what causes the universe’s most powerful explosions. .2. Via the Max Planck Institute and the German space agency DLR “A new set of eyes heads for space” A massive piece of kit called the “extended ROentgen Survey with an Imaging Telescope Array’ (eROSITA) X-ray telescope”, is currently being attached to a spacecraft called the Spektrum-Röntgen-Gamma (SRG), set to be launched from the Kazakh steppe any day now. .3. via the SETI Institute and Breakthrough Listen. “The Largest data set in SETI history has been released to the public.” Breakthrough Listen—the astronomical program searching for signs of intelligent life in the Universe—has submitted two publications to leading astrophysics journals, describing the analysis of its first three years of radio observations and the availability of a petabyte of radio and optical telescope data.

The Celeste Project: Celeste is a collaboration between MIT, UC Berkeley, Harvard, Julia Computing, Intel, and NERSC (the DoE's supercomputing center). They recently managed to calculate the first comprehensive statistical catalog of astronomical objects in the visible universe. That's over 188 million stars and galaxies! Using some nifty new methods they developed, the collaboration managed to complete the entire calculation in only 15 minutes. We believe this system will massively accelerate astronomy research, especially once scientists start receiving higher-resolution images from new telescopes like the LSST and the James Webb Space Telescope.   Purchase the brand new Ad Astra merch here!!!   Further Reading: Info about Julia   Here are some Celeste pointers Honored for HPC Innovation Excellence Celeste Enhancements Create New Opportunities In Sky Surveys A New Model For Cataloging the Universe   and some other projects at NERSC Big Science Problems, Big Data Solutions A Look At Deep Learning for Science     Follow Ad Astra on Twitter at @AdAstra_Podcast, on Facebook, and subscribe to the mailing list for future updates and events!

Le LSST n'est pas le plus grand télescope du monde, loin de là, mais c'est peut-être le plus innovant de tous les grands télescopes actuellement en cours de fabrication. LSST est l'acronyme de Large Synoptic Sky Survey, comme son nom l'indique, il a pour but d'imager la totalité du ciel (austral). Le LSST va ainsi scanner le ciel en continu, à la recherche d'objets évoluant rapidement temporellement (des supernovas ou des étoiles variables par exemple) ou spatialement (des astéroïdes)...
