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 12 parsecs, exoplanets, jellyfish galaxies, diffuse ionized gas, and general overall weirdness.

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.
The group of galaxies called the IC 1860 Group looks like it was recently disturbed by a spiral galaxy falling into it.
The nearby star DENIS J104814.7-395606 is cool (in the sense that it is awesome) because it is so cool (in the sense that it has a very low surface temperature for a star).
PSR 0820+02 is the second pulsar ever discovered to be in a binary star system.
A number of peculiarities about the lenticular galaxy NGC 5102 indicate that a dwarf galaxy fell into it several hundred million years ago.
NGC 55 has the interesting distinction of being the closest galaxy to Earth that is seen edge-on, and it also contains an ultraminous X-ray source (ULX) uncreatively named NGC 55 ULX.
NGC 281, which is also called the Pacman Nebula, is a place where star formation has been triggered two different ways, although the stars are not chased by any Ghost Nebulae.
Even though it may be rather ordinary from a scientific standpoint, the open cluster Messier 23 is a very popular with amateur astronomers.
Everything about the triple star system V505 Sgr looked normal aside from an abrupt change in the orbits of the stars sometime around the year 2000.
The short gamma ray burst GRB 100206A was found in a luminous infrared galaxy, which is very unusual place to find such gamma ray bursts.

4U 1957+115 is a low mass X-ray binary, a binary star system with a normal star about the size of the Sun and a relatively small black hole three times the mass of the Sun, and it also has an unfortunately confusing name.
The extremely bright, point-like emission from J1955+5131 in visible light and radio waves makes it useful for matching up images from different parts of the electromagnetic spectrum as well as an interesting object in its own right.
Despite the variability of the gamma radiation from J0510+1800, this blazar is used as a flux calibrator at millimeter and submillimeter wavelengths.
WASP-103 has an acronym for a name and also has a gaseous planet orbiting so close to it that the planet is in danger of being destroyed.
BV Centaurus is an unusual example of a class of U Gem cataclysmic variable stars in which a white dwarf is stripping gas from a companion star.
ELAIS N1 is a extragalactic deep field selected specifically for identifying many distant, faint galaxies at infrared wavelengths.
Psi Capricorni was the first star other than the Sun where the phenomenon of differental rotation was ever measured.
Abell 85 is a large, nearby cluster of galaxies with so many things happening inside that it could be called a ball of chaos.
