The globular cluster Messier 54 is not part of our galaxy but actually the nuclear stellar core of a dwarf galaxy that has nealy been completely gravitationally torn apart by the Milky Way.

Algol-type variable affected by light travel time effect caused by two smaller red dwarfs on wide orbits; this makes the variability period of the central two stars appear to vary.

Abell 1142 is a peculiar cluster of galaxies that has formed from the merger of two smaller clusters, and its center contains nothing but gas.

SN 2002cx was the first supernova ever identified in a subclass of objects now called Type Iax supernovae.

The stars in the open cluster NGC 6253 contain abnormally large amounts of elements heavier than hydrogen and helium, and no one is quite certain why.

GJ 887 is a very close red dwarf with two exoplanets (and a potential third) that almost look like they could harbor life except for one potential problem.

The awkwardly-named Segue 2 is (as of the time of the publication of this episode) the smallest galaxy anyone has ever found.

Messier 74 is just a very nice looking face-on spiral galaxy, which has made it quite useful for many different types of astrophysical analyses.

Infrared observations of SN 1995N indicate that the material ejected by the explosion may have produced a huge amount of dust.

The 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.

HD 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.

NGC 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.
