George"s Random Astronomical Object

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

Object 63: A Rant About Variable Star Classifications

George"s Random Astronomical Object ·

2021/12/27

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...

George"s Random Astronomical Object ·

2021/12/13

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 57: One of 57 Varieties of Active Galactic Nuclei

George"s Random Astronomical Object ·

2021/10/04

Object 56: The Next Best Thing to an Exoplanet

George"s Random Astronomical Object ·

2021/09/20

Object 51: Swipe Right for Gamma Rays

George"s Random Astronomical Object ·

2021/07/12

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

George"s Random Astronomical Object ·

2021/06/28

Object 49: Big in the South

George"s Random Astronomical Object ·

2021/06/14

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.
