George's Random Astronomical Object episodes
- Object 139: RecoilThe galaxy 3C 186 features a supermassive black hole with a mass several billions of times the mass of the Sun that has been ejected 36000 light years out of the galaxy's nucleus.9 min
- Object 138: A Weird Example of a Weird Subclass of a Weird Class of Objects4U 1850-087 is an ultracompact binary star system consisting of a whtie dwarf and a neutron star orbiting each other so closely that the neutron star can strip the outer layers off of the white dwarf.9 min
- Object 137: The Bedtime Story of the Black Hole that was Too Large for its GalaxyThe elliptical galaxy NGC 4291 contains a supermassive black hole that is unusually massive in comparison to the rest of the galaxy.9 min
- Object 136: BariumHD 11397 is one of very few Sun-like stars that might seem ordinary but actually contain abnormally large amounts of heavy elements, most notably barium, that they could not have formed themselves.11 min
- Object 135: Feedback TimeNGC 3801 is one of the very few nearby galaxies where astronomers can see jets from an active galactic nucleus disrupting star formation in the galaxy in a process known as feedback.10 min
- Object 134: Not Dead YetThe star at the center of the planetary nebula NGC 7094 is almost but not quite a white dwarf, making it a rather unusual object for astronomers to look at.8 min
- Object 133: Strong Arm TacticsOne of the spiral arms in the galaxy NGC 3110 is producing unusually huge amounts of new stars as well as unusually huge amounts of infrared emission.10 min
- Object 132: I Need a 2002 Pop Culture ReferenceThe radio source PMN J0134-0931 created a lot of excitement in 2002 when people discovered that it was a quasar gravitationally lensed by another galaxy in front of it, they were really excited.12 min
- Object 131: Get To Know Your Ultrafaint NeighborsHydrus I is a very small, ultrafaint dwarf galaxy orbiting the Milky Way that was accidentally (or, to use the technical term, serendipitously) found by the Dark Energy Survey.10 min
- Object 130: Putting It All TogetherNGC 4261 was made famous when Hubble Space Telescope observations in the 1990s showed that this elliptical galaxy contains a supermassive black hole.8 min
