The gamma ray burst GRB 020819 took place in a galaxy containing so much light-obscuring interstellar dust that people initially misidentified which galaxy contained the burst.

The nearby Sun-like star HD 69830 may have three exoplanets orbiting it, but astronomers seem more focused on trying to understand a hard-to-explain dust disk in the star system.

Z Ursa Minor belongs to a class of variable stars that occasionally produce puffs of dust, but this is not the weeirdest thing about them.

The nearby face-on spiral galaxy Messier 101 is one of the most popular galaxies in the sky for astronomers to study, particularly in terms of studying the relative abundances of various elements within the galaxy.

A 0535+26 is a rather unusual star system called a Be high mass X-ray binary that periodically produces bursts of X-ray emission.

Hen 2-113 is a rather unusual planetary nebula that formed not when a Sun-like star died but when a large, massive, and extraordinarily hot Wolf-Rayet star blew away its outer hydrogen layers.

The quasar PKS 2126-158 has been popular to observe because astronomers can see many different things between the quasar and Earth, including an entire cluster of galaxies, that are absorbing light from the quasar.

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.

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.

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.

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.
