Beta Ceti is a relatively close giant star where helium fusion has been triggered in its core, but it's a bit unusual compared to other stars that have reached this stage in their evolution.

Wolf 1069 is another nearby red dwarf with an exoplanet, but this time, the exoplanet is more likely to harbor life than other nearby red dwarfs with exoplanets that I may have discussed in previous episodes.

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.

DI Pegasi is a star system with two eclipsing stars in its center that orbit each other every 17 hours and 5 minutes and two smaller stars on very wide orbits that gravitationally tug on the central two stars, which has the effect that the variability of the star system's brightness seems to change over decades of time.

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.

PSR J1518+4904 is one of the very few identified double neutron stars, and it has provided opportunities to perform unique measurements on the objects.

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.
