Only the magnetometer and plasma wave subsystem remain active. •       Engineers are developing 'the Big Bang' — a plan to swap older components with lower-power alternatives — to extend operations into the 2030s. Testing on Voyager 2 is planned for May/June 2026; Voyager 1 to follow no sooner than July. •       Source: NASA JPL — https://www.jpl.nasa.gov/news/nasa-shuts-off-instrument-on-voyager-1-to-keep-spacecraft-operating/   Story 2 — Curiosity Rover Finds Organic Molecules on Mars •       Published April 21 in Nature Communications, the study describes the first use of the TMAH chemical experiment on another planet. •       More than 20 organic molecules were detected in clay-rich sandstone from the Glen Torridon region of Gale Crater, preserved for over 3.5 billion years. •       Discoveries include a nitrogen-bearing molecule structurally similar to DNA precursors — never before confirmed on Mars — and benzothiophene. •       The experiment cannot determine whether molecules are biological, geological, or meteoritic in origin. Future missions including Rosalind Franklin and Dragonfly will build on the technique. •       Source: phys.org — https://phys.org/news/2026-04-mars-rover-compounds.html   Story 3 — Black Hole Jets in Cygnus X-1 •       Curtin University-led study published April 16 in Nature Astronomy directly measures the instantaneous power of black hole jets for the first time. •       The jets in the Cygnus X-1 system carry energy equivalent to 10,000 suns and travel at approximately half the speed of light (150,000 km/s). •       Researchers used the companion star's stellar winds to 'bend' the jets, allowing calculation of their real-time power — a technique compared to watching wind deflect a fountain. •       About 10% of the energy released as matter falls into the black hole is carried away by the jets — confirming a long-held theoretical assumption. •       The measurement will help calibrate future observations from the Square Kilometre Array Observatory, currently under construction in WA. •       Source: ScienceDaily — https://www.sciencedaily.com/releases/2026/04/260416071949.htm   Story 4 — SpaceX 600th Rocket Landing •       SpaceX completed its 600th successful Falcon booster landing on April 19, 2026, during the Starlink 17-22 mission from Vandenberg SFB. •       Booster B1097 landed on drone ship 'Of Course I Still Love You' for its eighth successful recovery. The milestone arrived just 7 months after the 500th landing. •       The tally includes 496 drone ship landings and 104 ground landings, per SpaceX VP Kiko Dontchev. •       SpaceX's Starlink constellation now numbers over 10,275 satellites in orbit. •       Source: Space.com — https://www.space.com/space-exploration/launches-spacecraft/spacex-starlink-17-22-b1097-vsfb-ofisly-600th-falcon-landing   Story 5 — Artemis Spacesuit Crisis •       NASA's Office of Inspector General report (released April 20) warns that next-generation Artemis spacesuits may not be ready until 2031 — three years after the stated 2028 target. •       The xEVAS programme began as a two-company competition (Axiom Space + Collins Aerospace). Collins has effectively been removed after missing milestones. Axiom is now the sole contractor for the lunar surface suit. •       OIG analysis: based on an 8.7-year historical average from contract award to first flight for comparable NASA programmes, Axiom's 2022 award points to a 2031 delivery. •       NASA Administrator Isaacman has publicly maintained confidence in the 2028 date. Axiom plans a suit demonstration in 2026 on the ISS or during an Artemis mission. •       A separate risk: if the ISS variant of the suit slips past 2030, the Station could run out of operational EVA suits before decommissioning. •       Additional Artemis delays: SpaceX lunar Starship at least 2 years late; Blue Origin Blue Moon at least 8 months late (per separate March OIG report). •       Source: SpaceDaily — https://spacedaily.com/sd-n-the-spacesuit-gap-why-artemis-iiis-2028-landing-date-is-already-slipping/   Story 6 — Skywatching: Moon & Jupiter Conjunction •       Tonight (April 22), the half moon sits approximately 3 degrees from Jupiter in the constellation Gemini, near the stars Castor and Pollux. •       Visible to the naked eye in the western/northwestern sky after sunset. Binoculars will reveal Jupiter's four Galilean moons. •       Southern Hemisphere viewers: look northwest after dark; viewing window narrows the further south you are. •       Source: Space.com — https://www.space.com/stargazing/the-moon-and-jupiter-steal-the-show-after-sunset-on-april-22Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

Astronomy Daily — Season 5, Episode 70 Monday, March 23, 2026   In today's episode, Anna and Avery cover six stories spanning a live European rocket launch attempt, a sixty-year-old NASA emergency brought back to life through newly surfaced photographs, a cosmic explosion caught only by its echo, the fight to preserve the night sky, a supply run to the ISS with an unexpected complication, and a first-of-its-kind discovery involving brown dwarf stars.   Story 1: Europe's Spectrum Rocket — Bid for Orbit Today Isar Aerospace's Spectrum rocket is attempting its second test flight today — its qualification mission for ESA's European Launcher Challenge. Launching from Andøya Spaceport in Norway, the mission carries five CubeSats and one experiment from European universities and companies, all supported by ESA's Boost! program. If successful, it would mark a landmark moment for European sovereign access to space. Source: ESA — Spectrum's Qualifying Second Launch Story 2: Neil Armstrong — The Gemini 8 Emergency Sixty years ago this month, Neil Armstrong and David Scott survived one of NASA's most dangerous pre-Apollo emergencies aboard Gemini 8. A spacecraft malfunction sent the capsule into an uncontrolled spin reaching one revolution per second. Never-before-seen photographs of Armstrong's recovery have been donated to the Armstrong Air and Space Museum in Wapakoneta, Ohio. Source: Phys.org — Space News Story 3: Astronomers Catch the Echo of a Billion-Sun Explosion Using the ASKAP radio telescope in Western Australia, astronomers identified ASKAP J005512-255834 — a radio signal representing the most convincing "orphan afterglow" of a gamma-ray burst ever detected. The original explosion went unseen because its jet wasn't aimed at Earth, but the lingering radio echo has been detectable for over 1,000 days. Research published in The Astrophysical Journal. Source: The Conversation — A Cosmic Explosion With the Force of a Billion Suns Story 4: The Fight to Save the Night Sky The Royal Astronomical Society, ESA, and the International Astronomical Union have filed formal objections to the FCC over two proposed satellite constellations: SpaceX's application for up to one million orbiting AI data centre satellites, and Reflect Orbital's proposal for 50,000 space mirrors each four times brighter than the full Moon. Experts warn the proposals could permanently transform humanity's view of the night sky.

Join hosts Anna and Avery for an exciting journey through today's most compelling space stories. We explore Mercury's surprising geological activity, NASA's TESS satellite recovery, a frigid Earth-like exoplanet discovery, an accelerated ISS crew launch, runaway black holes tearing through space, and the scientific opportunities of a potential lunar asteroid impact in 2032.### Episode Highlights**Mercury's Hidden Activity**New research reveals that Mercury, long considered geologically dead, is still actively losing volatile materials from its interior. Using AI analysis of 100,000 MESSENGER images, scientists have mapped 400 bright slope streaks that indicate ongoing geological processes. The BepiColombo mission will provide unprecedented new data when it arrives at Mercury.**TESS Satellite Recovery**NASA's planet-hunting TESS satellite recently entered safe mode after a command error caused solar panel misalignment. The spacecraft successfully recovered, demonstrating the importance of built-in safeguards. NASA is reviewing procedures to prevent future incidents.**Ice-Cold Earth Twin**Astronomers have discovered HD 137010 b, an Earth-like exoplanet 146 light-years away that could be as cold as minus 90°F. Despite frigid temperatures, it orbits within its star's habitable zone, offering insights into the diversity of potentially habitable worlds.**Crew-12 Launch Advanced**SpaceX and NASA have moved up the Crew-12 launch to February 11, four days earlier than planned, to provide relief for the three-person skeleton crew managing the ISS after the first-ever medical evacuation from the station.**Runaway Black Holes Confirmed**The James Webb Space Telescope has confirmed the first runaway supermassive black hole, ejected from its galaxy and leaving a 200,000 light-year trail of newborn stars. Traveling at 1,600 km/s, this discovery validates 50-year-old theoretical predictions.**Moon Impact Opportunity**Asteroid 2024 YR4 has a 4% chance of striking the Moon on December 22, 2032. While posing risks to satellites and Earth, such an impact would provide unprecedented scientific data on lunar geology, create spectacular meteor displays, and deliver free lunar samples to Earth.### Featured Stories1. **Mercury Still Geologically Active** - University of Bern researchers discover 400 bright streaks indicating ongoing volatile loss (Source: Space Daily)2. **TESS Satellite Command Error** - NASA's exoplanet hunter recovers from safe mode after solar panel misalignment (Source: Daily Galaxy)3. **Frigid Earth-Like Planet Discovery** - HD 137010 b joins the search for Earth's twin despite extreme cold (Source: Daily Galaxy)4. **ISS Crew-12 Launch Moved Up** - February 11 launch provides relief after historic medical evacuation (Source: Space.com)5. **First Confirmed Runaway Black Hole** - JWST observations validate theoretical predictions with stunning stellar trail (Source: Phys.org/Science Sources)6. **Asteroid 2024 YR4 Lunar Impact** - 4% chance creates scientific opportunity and satellite risk in 2032 (Source: Universe Today)### HostsAnna and Avery### Links & Resources- Website: astronomydaily.io- Social Media: @AstroDailyPod (X, Facebook, Instagram, YouTube)- Subscribe for daily space news and updatesBecome a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

There seems to be a sea of things that we can find overwhelming these days. How do we move through it all without becoming bogged down? In this episode, producer Sam talks to Phoebe Atkinson, Lissy Cole, and Rudi Robinson about the ways they see and approach overwhelming circumstances. Later on, Petra sits down with Rachel Kitchens, a spiritual director, to talk about her own experiences and a handful of practical tips. To be clear, this episode doesn't address the overwhelming nature of serious physical or mental health issues. The sense of overwhelm focussed on applies to otherwise healthy people who find either personal or global circumstances to be just too much at times. Wherever you're at, feel free to join us.

Abstract: The temporal dynamics within the semantic brain network and its dependence on stimulus and task parameters are still not well understood. Here, we addressed this by decoding task as well as stimulus information from source-estimated EEG/MEG data. We presented the same visual word stimuli in a lexical decision (LD) and three semantic decision (SD) tasks. The meanings of the presented words varied across five semantic categories. Source space decoding was applied over time in five ROIs in the left hemisphere (Anterior and Posterior Temporal Lobe, Inferior Frontal Gyrus, Primary Visual Areas, and Angular Gyrus) and one in the right hemisphere (Anterior Temporal Lobe). Task decoding produced sustained significant effects in all ROIs from 50-100 ms, both when categorising tasks with different semantic demands (LD-SD) as well as for similar semantic tasks (SD-SD). In contrast, semantic word category could only be decoded in lATL, rATL, PTC and IFG, between 250-500 ms. Furthermore, we compared two approaches to source space decoding: Conventional ROI-by-ROI decoding and combined-ROI decoding with back-projected activation patterns. The former produced more reliable results for word-category decoding while the latter was more informative for task-decoding. This indicates that task effects are distributed across the whole semantic network while stimulus effects are more focal. Our results demonstrate that the semantic network is widely distributed but that bilateral anterior temporal lobes together with control regions are particularly relevant for the processing of semantic information.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.09.16.299305v1?rss=1 Authors: Allouch, S., Yochum, M., Kabbara, A., Duprez, J., Khalil, M., Wendling, F., HASSAN, M., Modolo, J. Abstract: Understanding the dynamics of brain-scale functional networks at rest and during cognitive tasks is the subject of intense research efforts to unveil fundamental principles of brain functions. To estimate these large-scale brain networks, the emergent method called electroencephalography (EEG) source connectivity has generated increasing interest in the network neuroscience community, due to its ability to identify cortical brain networks with good spatio-temporal resolution, while reducing mixing and volume conduction effects. However, the method is still immature and several methodological issues should be carefully accounted for to avoid pitfalls. Therefore, optimizing the EEG source connectivity pipelines is required, which involves the evaluation of several parameters. One key issue to address those evaluation aspects is the availability of a ground truth. In this paper, we show how a recently developed large-scale model of brain-scale activity, named COALIA, can provide to some extent such ground truth by providing realistic simulations (epileptiform activity) of source-level and scalp-level activity. Using a bottom-up approach, the model bridges cortical micro-circuitry and large-scale network dynamics. Here, we provide an example of the potential use of COALIA to analyze the effect of three key factors involved in the EEG source connectivity pipeline: (i) EEG sensors density, (ii) algorithm used to solve the inverse problem, and (iii) functional connectivity measure. Results show that a high electrode density (at least 64 channels) is needed to accurately estimate cortical networks. Regarding the inverse solution/connectivity measure combination, the best performance at high electrode density was obtained using the weighted minimum norm estimate (wMNE) combined with the weighted phase lag index (wPLI). The COALIA model and the simulations used in this paper are freely available and made accessible for the community. We believe that this model-based approach will help researchers to address some current and future cognitive and clinical neuroscience questions, and ultimately transform EEG brain network imaging into a mature technology.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.07.23.217786v1?rss=1 Authors: Mehrkanoon, D. S. Abstract: Synchronous oscillations of neuronal populations support resting-state cortical activity. Recent studies indicate that resting-state functional connectivity is not static, but exhibits complex dynamics. The mechanisms underlying the complex dynamics of cortical activity have not been well characterised. Here, we directly apply singular value decomposition (SVD) in source-reconstructed electroencephalography (EEG) in order to characterise the dynamics of spatiotemporal patterns of resting-state functional connectivity. We found that changes in resting-state functional connectivity were associated with distinct complex topological features, ''Rich-Club organisation'', of the default mode network, salience network, and motor network. Rich-club topology of the salience network revealed greater functional connectivity between ventrolateral prefrontal cortex and anterior insula, whereas Rich-club topologies of the default mode networks revealed bilateral functional connectivity between fronto-parietal and posterior cortices. Spectral analysis of the dynamics underlying Rich-club organisations of these source-space network patterns revealed that resting-state cortical activity exhibit distinct dynamical regimes whose intrinsic expressions contain fast oscillations in the alpha-beta band and with the envelope-signal in the timescale of $
