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.

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.

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.

4U 1850-087 is an ultracompact binary star system consisting of a whtie dwarf and a neutron star orbiting each other so closely that the neutron star can strip the outer layers off of the white dwarf.

The elliptical galaxy NGC 4291 contains a supermassive black hole that is unusually massive in comparison to the rest of the galaxy.

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.

The star at the center of the planetary nebula NGC 7094 is almost but not quite a white dwarf, making it a rather unusual object for astronomers to look at.

One of the spiral arms in the galaxy NGC 3110 is producing unusually huge amounts of new stars as well as unusually huge amounts of infrared emission.

The radio source PMN J0134-0931 created a lot of excitement in 2002 when people discovered that it was a quasar gravitationally lensed by another galaxy in front of it, they were really excited.

Hydrus I is a very small, ultrafaint dwarf galaxy orbiting the Milky Way that was accidentally (or, to use the technical term, serendipitously) found by the Dark Energy Survey.

NGC 4261 was made famous when Hubble Space Telescope observations in the 1990s showed that this elliptical galaxy contains a supermassive black hole.
