Object 36: Seventeen Ways to Oscillate
14/12/2020 Duración: 11minHD 60435 is a nearby example of a class of stars called rapidly oscillating Ap stars that can change brightness in just a few minutes.
-
Object 35: The Ursa Major Eye Test
30/11/2020 Duración: 14minMizar 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.
-
Object 34: Longer Than This Podcast Episode
16/11/2020 Duración: 09minThe 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.
-
Object 33: Part of a Vegetarian Sausage
02/11/2020 Duración: 12minMessier 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.
-
Object 32: Synonyms for Large
19/10/2020 Duración: 09minAs 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.
-
Object 31: Jelly Bean Analysis
05/10/2020 Duración: 10minThe 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.
-
Object 30: Measure the Correct Distance and Win a Prize
21/09/2020 Duración: 13minNGC 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.

01/06/2020 Duración: 14minNGC 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.
-
Object 21: Retro Gaming and Star Formation
18/05/2020 Duración: 09minNGC 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.
