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 53: Fortified with Iron 09.08.2021

Most globular clusters are among the first stars to form in the universe, but the globular cluster NGC 6352 seems abnormally young in comparison.

Object 52: The 10 Year Long Discovery 26.07.2021

It took 10 years of observations for astronomers to determine that the star HD 154345 had a Jupiter-like exoplanet orbiting it.

Object 51: Swipe Right for Gamma Rays 12.07.2021

While the gamma ray burst GRB 090926A itself might be interesting to some astronomers (particularly desperate gamma ray astronomers), the interstellar gas between the burst and Earth may be even more interesting.

Object 50: It's Blue but not Blueberry 28.06.2021

IC 10 is a nearby starburst, a type of galaxy that is forming stars at a very high rate (for its size) that should not be confused with the fruit flavored candy.

Object 49: Big in the South 14.06.2021

The cluster of galaxies Abell S1063 was only reported as a discovery in the 1980s, but it has attracted a lof of attention because of how it gravitationally distorts the light of galaxies behind it.

Object 48: It's Too Obvious To Say It's Complex 31.05.2021

The S254-S258 Complex is a chain of ionized gas bubbles connected by a filament of cold interstellar gas and dust where star are forming in a complicated (or possibly complex) way.

Object 47: BYOB 17.05.2021

NGC 3504 contains three rings, two bars, and a supermassive black hole but no locations licensed to sell alcohol (as far as astronomers know).

Object 46: Stability within a Cataclysm 03.05.2021

An exoplanet has managed to stay in a stable orbit around LX Serpentis despite the fact that it is a cataclysmic binary star system with a chaotic past.

Object 45: Try Turning it Off and On Again 19.04.2021

Markarian 590 contains an active galactic nucleus with a supermassive black hole, and the region around the black hole has strangely changed in brightness a couple of times in the past 50 years.

Object 44: The Understated Exoplanet Discovery 05.04.2021

When it was discovered, WD 0806-661B was described as a very cool, very low mass brown dwarf, but it could actually be better characterized as a large exoplanet.

Object 43: Does It Dark Matter? 22.03.2021

The dwarf galaxy NGC 1052-DF2 may be one of the very few galaxies that contains no dark matter, although the non-existence of something we cannot see in this galaxy is still being debated.

Object 42: The Inside Joke Galaxy 08.03.2021

The dust disk in the spiral galaxy NGC 891 is so useful for studying interstellar dust that many astronomers show up to conferences with science results specifically about this spiral galaxy.

Object 41: Bobbins 22.02.2021

BoBn 1 is not only a planetary nebula with an odd-to-pronounce name but also one of a very few planetary nebulae that have been found in the Milky Way's halo.

Object 40: Sugar Formation 08.02.2021

IRAS 16293-2422 is a complex protostellar object that contains multiple objects that are forming into Sun-like stars.

Object 39: Sort of Faster than the Speed of Light 25.01.2021

Gas ejected from the center of the quasar 1642+690 looks like it's travelling faster than the speed of light even though it isn't.

Object 38: The Clickbait Star 11.01.2021

HD 220140 is often referred to as a naked young star, and it is a source of both X-ray emission and double entendres.

Object 37: Blowing Bubbles (or Cavities) 28.12.2020

Hickson Compact Group 62 contains hot intracluster gas with two large cavities (which I want to call bubbles) that formed from gas that was blown out of the galaxy at the centre of the group.

Object 36: Seventeen Ways to Oscillate 14.12.2020

HD 60435 is a nearby example of a class of stars called rapidly oscillating Ap stars that can change brightness in just a few minutes.

Object 35: The Ursa Major Eye Test 30.11.2020

Mizar and Alcor have been visible as a double star since ancient times, but as technology has progessed over the centuries, astronomers have discovered that Mizar and Alcor are not just one pair of stars.

Object 34: Longer Than This Podcast Episode 16.11.2020

The gamma ray burst GRB 111209A was notable for being almost seven hours long, which is much longer than gamma ray bursts normally last as well as much longer than a typical Ariana Grande concert.

Object 33: Part of a Vegetarian Sausage 02.11.2020

Messier 56 is a particularly old globular cluster that attracts a lot of attention from professional astronomers, although amateur astronomers have a tendency to overlook it.

Object 32: Synonyms for Large 19.10.2020

As a large elliptical galaxy with a supermassive black hole and supersized jets of gas emerging from its nucleus, NGC 6251 inspires some astronomers to use thesauruses.

Object 31: Jelly Bean Analysis 05.10.2020

The red dwarf GJ 3470 has a gaseous exoplanet orbiting it in such a way that the planet passes between the star and the Earth, allowing astronomers to examine the atmosphere of the exoplanet.

Object 30: Measure the Correct Distance and Win a Prize 21.09.2020

NGC 3621 is one of a few galaxies where its distance has been measured with high accuracy using Cepheids and other stars with known brightness, thus making it very important for measuring the expansion of the universe.

Object 29: High Contrast 07.09.2020

A project using an interesting combination of methods was able to find a very faint red dwarf in orbit around the bright, nearby star Zeta Virginis.
