George's Random Astronomical Object episodes
- Object 9: A Cruise Holiday with a Peculiar Carbon StarThe star HD 214714 contains not only a large amount of carbon in its stellar atmosphere but also a peculiar combination of other heavy elements as well.10 min
- Object 8: A Misbehaving LIRGII Zw 96 is a luminous infrared galaxy (LIRG) where most of the infrared emission comes from some type of off-center region, which is weird compared to most other LIRGs.11 min
- Object 7: Circles within Circles30 Ari contains four stars and an exoplanet all arranged in a rather complex set of nested orbits.12 min
- Object 6: Extra PeculiarHD 98851 is both an Am chemically peculiar star and a delta Scuti variable star, and it has two different pulsation cycles, which makes it really peculiar.9 min
- Object 5: Some Unexpected HeliumRV Octantis would be considered a run-of-the-mill RR Lyrae variable star if it wasn't for the unexpected discovery of helium in its atmosphere.11 min
- Object 4: A Damp Lyman Alpha ElephantThe most interesting thing about the quasar LBSQ 0058+0155 is not the quasar itself but the galaxy between the quasar and Earth.14 min
- Object 3: Room TemperatureHD 85512 is a nearby star slightly smaller and more orange than the Sun. It happens to have an exoplanet that could be close to Earth-like.9 min
- Object 2: Variable VariabilityHS Hydrae is a variable eclipsing binary star, which sounds more unusual than it actually is. However, it's precessing, which is not only unusual but also causes the variability to vary over time.9 min
- Object 1: Not the PopeThe Leo IV Dwarf Galaxy is one of several ultra faint dwarf galaxies that orbit the Milky Way. Galaxies like this are weird relics of when the universe first formed; they contain very old stellar populations and abnormally large amounts of dark matter.9 min
