George's Random Astronomical Object episodes
- Object 39: Sort of Faster than the Speed of LightGas 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.9 min
- Object 38: The Clickbait StarHD 220140 is often referred to as a naked young star, and it is a source of both X-ray emission and double entendres.10 min
- Object 37: Blowing Bubbles (or Cavities)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.10 min
- Object 36: Seventeen Ways to OscillateHD 60435 is a nearby example of a class of stars called rapidly oscillating Ap stars that can change brightness in just a few minutes.12 min
- Object 35: The Ursa Major Eye TestMizar 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.15 min
- Object 34: Longer Than This Podcast EpisodeThe 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.10 min
- Object 33: Part of a Vegetarian SausageMessier 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.13 min
- Object 32: Synonyms for LargeAs 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.10 min
- Object 31: Jelly Bean AnalysisThe 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.11 min
- Object 30: Measure the Correct Distance and Win a PrizeNGC 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.14 min
