Indy wants you to be a casual astronomy fan, Samantha read the ballet memoir Swan Dive by Georgina Pazcoguin, and we get ready to explore 1950s sci-fi with The Day The Earth Stood Still! Plus wedding talk, Mark Messier, why sports journalism and Edmonton Oilers fans make Indy look at stars, realtor names, theremin, and more!   The Day The Earth Stood Still full movie: https://archive.org/details/The.Day.The.Earth.Stood.Still1951 The Day The Earth Stood Still Trailer: https://www.youtube.com/watch?v=sVRptT6fa7I&ab_channel=TrailerChan   Messier 43 or M43, also known as De Mairan's Nebula and NGC 1982, is a star-forming nebula with a prominent H II region in the equatorial constellation of Orion. It was discovered by the French scientist Jean-Jacques Dortous de Mairan some time before 1731,[2] then catalogued by Charles Messier in 1769.[a] It is physically part of the Orion Nebula (Messier 42), separate from that main nebula by a dense lane of dust known as the northeast dark lane.[4] It is part of the much larger Orion Molecular Cloud Complex.   Pillars of Creation is a photograph taken by the Hubble Space Telescope of elephant trunks of interstellar gas and dust in the Eagle Nebula, in the Serpens constellation, some 6,500–7,000 light-years (2,000–2,100 pc; 61–66 Em) from Earth.[1] They are so named because the gas and dust are in the process of creating new stars, while also being eroded by the light from nearby stars that have recently formed.[2] Taken on April 1, 1995, it was named one of the top ten photographs from Hubble by Space.com.[3] The astronomers responsible for the photo were Jeff Hester and Paul Scowen from Arizona State University. The region was rephotographed by ESA's Herschel Space Observatory in 2011, and again by Hubble in 2014 with a newer camera. Georgina Pazcoguin is an American ballerina. She is a soloist with the New York City Ballet, and is known for challenging racism in ballet,[2] and for performing on Broadway.

Dr Roberta Paladini talks about the space-based Herschel Space Observatory, which was the largest infrared telescope ever launched. It looked at the sky in the far infrared, and discovered an abundance of water in star-forming regions.

In this public lecture, astrophysicist Dr Chris North takes its audience on a journey through space to understand the most distant stars and galaxies, exploring the findings of the Herschel Space Observatory. Dr North has worked on a number of space missions and is currently part of the Herschel Observatory team, looking at far-infrared light from stars forming in our galaxy and across the Universe.

Download Episode! A podcast extra episode to get you in the mood for the biannual dark sky weekend run by the podcast crew. We have BBC's The Sky at Night's Chris North joining us again to give a talk on the Herschel Space Observatory and Cardiff Uni's Jeni Millard explaining galaxies and dark matter. And of course, 3 nights of enjoying the wonders of truly dark skies. If you're not coming to AstroCamp in April 2014, there's still a sky guide in this episode to give you stargazing inspiration wherever you are.

Emerging from the cosmic web, galaxy clusters are the most massive gravitationally bound structures in the universe. Thought to have begun their assembly at 2 < z < 3, i.e. 10 to 11 billion years ago, clusters provide insights into the growth of large-scale structure as well as the physics that drives galaxy evolution. The redshift range 1 < z < 3 is a key epoch in their evolution. At z ∼ 1.5, elliptical galaxies start to become the dominant population in cluster cores, and star formation in spiral galaxies is being quenched. But there is also evidence for a progressive increase in the amount of star formation that occurs in galaxy cluster cores at z ≳ 1.5. To understand the dependence of the formation mechanisms of massive galaxies with environment, we must focus on clusters at relatively unexplored redshifts z > 1.5 where major assembly is in progress. The search for galaxy clusters at high redshift, so far, has been mildly successful and only a handful of clusters at z > 1.5 have been confirmed. Because this redshift range was essentially unreachable with previous instrumentation, it was dubbed a ‘redshift desert’. The work presented in this thesis has made a major contribution to this field. The Clusters Around Radio- Loud AGN (CARLA) survey, a 400 hr targeted Warm Spitzer program, observed 420 radio-loud AGN (active galactic nuclei) at 1.3 < z < 3.2 across the full sky. Extensive literature over several decades shows that powerful radio-loud AGN preferentially reside in overdense environments. From this survey, we have identified a sample of ∼ 200 galaxy cluster candidates by selecting strong overdensities of color-selected sources. By studying the luminosity function of the CARLA cluster candidates, we showed that quenching is happening much earlier in clusters around radio-loud AGN than in field galaxy samples. This suggests that our targets may well be the most massive and evolved structures known to date at z > 1.5. We also showed that radio-loud AGN reside in denser environments than similarly massive galaxies. This makes high-redshift clusters around radio-loud AGN particularly interesting as they can reveal how galaxies in the most massive dark matter halos assembled. A complementary project, HERGE (Herschel Radio Galaxy Evolution Project) observed a sample of 71 radio galaxies at 1 < z < 5 at far-IR wavelengths with the Herschel Space Observatory. Supporting data in the mid-IR, partially in the near-IR and at sub-mm wave- lengths allow to study cluster fields in more detail. A pilot project on a single field showed that we can identify cluster members and constrain their star-formation properties. These projects laid the foundation for future work, which will make a significant impact on understanding the formation of the most massive structures over several billion years.

The Carina Nebula Complex is known to be an active star-formation region. This work presents a large catalogue of point-like sources assembled from archive data of the Infrared Array Camera (IRAC) onboard the Spitzer Space Telescope. This catalogue covers a region of 2.3 deg × 3.0 deg, which makes it the most extendended mid-infrared survey undertaken of the Carina Nebula Complex to date. From the catalogue a subsample of candidate young stellar objects is extracted utilising the fact that young stellar objects exhibit typical mid-infrared excesses. These catalogues are employed to characterise the young stellar population of the Carina Nebula Complex. Using them, it was possible to identify three new extended green objects and five compact green objects and find the probable sources for 28 further objects connected with jets emitted from young stars, such as molecular hydrogen emission-line objects and Herbig-Haro jets. For 17 of them, observational data from the near-infrared (from HAWK-I and 2MASS) to the far-infrared (from the Herschel Space Observatory) could be collected and their spectral energy distributions fitted. From the fit parameters, stellar characteristics such as stellar and disk masses could be estimated. No young stellar objects with masses above 10 M_sol could be evidenced, pointing towards an intermediate-mass population currently forming. It could be shown that the Gum 31 region on the outer periphery of the Carina Nebula Complex is not only part of the complex but also an important centre of star formation. A large sample of candidate young stellar object was obtained from the WISE All-Sky Data Release, which allowed a detailed comparison with both the candidate young stellar objects from the IRAC catalogue and those identified from Herschel observations. Evidence could be found that two modes of triggered star formation are going on in the HII region: Young stellar objects are found in and in front of dust pillars, which is an indicator of radiative triggering, and a ‘collect and collapse’ model of the region was shown to produce results in agreement with the observations. An objective and large-scale search for clusters of young stellar objects in the complex was performed using a nearest-neighbour algorithm. This search derived 22 clusters not described before. Nine of those are new detections in the fields of previous studies of clusters while the majority are found in fields surveyed for clusters for the first time here. Clusters are also found in agreement with previous studies where study fields overlap, thus corroborating the validity of the study. It is found that ∼40% of the young stellar objects in the Carina Nebula Complex occur in clusters while up to 60% are part of a distributed population. A total population for the 2.3 deg × 3.0 deg study field of ∼200 000 young stars is estimated.

Abstract: With the almost seamless transition from the Spitzer Space Telescope cryogenic mission (2003-2009) to the operation of the Herschel Space Observatory (2009-), it is no exaggeration to say that we have been enjoying a golden age of space infrared (IR)/submillimeter (Submm) astronomy in recent years. In this talk, I will report the results from the following three large extragalactic programs our group is currently conducting here at the Steward Observatory: (1) Herschel-Spitzer observations of galaxy clusters: gravitationally lensed galaxies and IR/Submm-bright cluster members (2) HST-Spitzer observations of 5.7
