George's Random Astronomical Object is a biweekly astronomy podcast featuring science discussions about astronomical objects at randomly selected locations in the sky. The wide range of topics discussed in the show include stars, variable stars, variable variable stars, supermassive black holes, ultracool dwarf stars, exoplanets, howler monkeys, infrared radiation, acronyms, more acronyms, starbursts, measurements of less than 12 parsecs, jellyfish galaxies, diffuse ionized gas, and general overall weirdness.

Episodes

Object 78: A Dwarf Galaxy with Something for Everyone 25.07.2022

Located within the Local Group, the dwarf galaxy IC 1613 has been popular with professional astronomers for a variety of reasons, and it is also a notable albeit difficult-to-see amateur astronomy object as well.

Object 77: Another 90's Gamma Ray Flashback 11.07.2022

GRB 980326 was the first gamma ray burst to be associated with a supernova, which was truly groundbreaking even if the astronomers who discovered it were probably using Netscape at the time.

Object 76: A Modern Non-Comet 27.06.2022

Sakurai's Object was discovered in 1996 by the amateur astronomer Yukio Sakurai, who had been searching for comets but who had instead found a dying star that had brifly undergone a final burst of fusion, causing it to increase dramatically in brightness.

Object 75: The Completely Unconcerned Open Cluster 13.06.2022

The open cluster NGC 3680 is 1.4 billion years old, making it unusually long-lived for such a cluster.

Object 74: The Brightest Star on the Argo 30.05.2022

As the second brightest star in the night sky, Canopus is associated with many different myths, yet as the closest yellow supergiant to Earth, the star is also scientifically important.

Object 73: A Very Distant Infrared Smudge 16.05.2022

The hyperluminous infrared galaxy IRAS 10214+4724 was the most distant infrared object seen by astronomers in the 1980s.

Object 72: No Face Masks Are Needed for Monocerotis 02.05.2022

GX Monocerotis is a evolved star near the end of its life that is expelling its outer gas layers, and because the star is in orbit in a binary star system, those gas layers have formed a spiral pattern.

Object 71: The Black Hole That Didn't Get Its Morning Coffee 18.04.2022

The center of the barred spiral galaxy Messier 71 contains multiple regions where stars are forming as well as an inactive supermassive black home that needs some caffeine.

Object 70: The Uncredited Star 04.04.2022

Eta Aquilae was the first Cepheid variable ever discovered, but this class of stars was named after Delta Cephei instead.

Object 69: How To Avoid Photobombing Asteroids 21.03.2022

The North Ecliptical Pole points to a location perpendicular to the plane of the Solar System, which makes it a unique place for certain types of astronomical observations.

Object 68: Reflections in Quotation Marks 07.03.2022

The spiral galaxy NGC 6814 is a source of strong but variable X-ray emission that astronomers are using to measure the mass of a supermassive black hole at its center.

Object 67: The Weird Sphere 21.02.2022

The abnormal-looking globular cluster Messier 71 is unusual in that its stars contain an excessive amount of heavy elements and in that it is being gravitationally shredded by the Milky Way.

Object 66: This Episode Brought to You by the Letter B 07.02.2022

The binary star system b Centauri contains an exoplanet named b Centauri b that, despite its confusing name, has changed astronomers' perspectives on how and where planets can form.

Object 65: The Infrared Twin 24.01.2022

Even though HD 106252 has an exoplanet orbiting it, astronomers are much more interested in the fact that HD 106252 looks very similar to the Sun.

Object 64: An Actual Use for Einstein's Famous Equation 10.01.2022

VER J0521+211 is a distant galaxy that produces gamma rays with such high energy that, when the gamma rays hit the Earth's atmosphere, the photons transform into electrons and positrons.

Object 63: A Rant About Variable Star Classifications 27.12.2021

UX Ari is an RS CVn type variable star system, which is a confusing way to classify variable star systems but which means that UX Ari contains two stars very close together with complex, interacting magnetic fields that produce all sorts of weird effects.

Object 62: Imaged Before the Hubble Space Telescope Was Fixed 13.12.2021

NGC 7457 was one of the first things imaged by the Hubble Space Telescope, which meant that the images of it were relatively blurry, but this is not the most interesting fact about this lenticular galaxy.

Object 61: Greater Than One 29.11.2021

SPT-CL J0546-5345 is an abnormally large cluster that formed very quickly after the Big Bang, which places some strong constraints of models of the formation and evolution of the universe.

Object 60: Conclusively Inconclusive 15.11.2021

UM 425 could be either a pair of very similar quasars at the same distance from Earth or a single quasar that has been gravitationally lensed so that it appears twice in the sky.

Object 59: Do Not Confuse With VV Cephei 01.11.2021

VW Cephei is an eclipsing binary star system containing two stars that are so close that they share an outer gas layer.

Object 58: Insert Guitar Riff Here 18.10.2021

Chi Cygni is a Mira-type variable star with some of the most extreme variations in brightness among any variable stars in the sky.

Object 57: One of 57 Varieties of Active Galactic Nuclei 04.10.2021

3C 147 is not the first object ever identified as a quasar, but it is sort of one of the first two objects ever called a quasar.

Object 56: The Next Best Thing to an Exoplanet 20.09.2021

Astronomers may not have found an exoplanet orbiting the star HD 191089, but they found the next best thing.

Object 55: The Quiet Kid on the Edge of the Playground 06.09.2021

The WLM Galaxy is located at the edge of the Local Group where it is relatively unaffected by everything happening around the Milky Way and the Andromeda Galaxy.

Object 54: Build Your Own Hypothesis At Home 23.08.2021

Jets of gas that are several light years long are emerging from the blue supergiant MWC 137, and no one knows why.
