Description

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, dwarf galaxies, supermassive black holes, ultracool dwarf stars, howler monkeys, infrared light, acronyms, more acronyms, measurements of less than 20 parsecs, exoplanets, jellyfish galaxies, diffuse ionized gas, and general overall weirdness.

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.
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.
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.
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.
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.

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.
IRAS 16293-2422 is a complex protostellar object that contains multiple objects that are forming into Sun-like stars.
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.
HD 220140 is often referred to as a naked young star, and it is a source of both X-ray emission and double entendres.
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.
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.
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.
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.
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.
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.
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.
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.
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.
PGC 43234 was a relatively uninteresting galaxy until its central supermassive black hole shredded a star in an event known as ASASSN-14li.
WR 40 is one of the brightest and best-studied Wolf-Rayet stars, a class of stars that are so hot that they are blowing themselves apart.
