The cluster Abell 168 formed from the merger of two smaller clusters, and this had many weird effects on the intracluster gas between the galaxies.

WD 2211-495 is a small, hot white dwarf with a rather unusual amount of heavy elements in its outer atmosphere, implying that something from a surrounding planetary system occasionally falls into the star.

UGC 7321 is an unusually flat (or superthin) spiral galaxy, which is indicative of how it has avoided gravitational interactions with other galaxies that could alter its shape.

The elliptical galaxy contains an abnormal amount of interstellar dust with no accompanying interstellar gas, which is weird.

Antlia 2, which was recently found orbiting the Milky Way, is the most diffuse galaxy that anyone has ever discovered up to this point in time.

UKS 1 probably lies on the far side of the Milky Way, and the light from the cluster is heavily obscured by interstellar dust, but even though it's hard to see, astronomers are still really interested in it.

R Aquarii could be described as one of the closest symbiotic binary star systems to Earth, but it's more complicated than that.

NGC 6052 looks like a spiral galaxy smashing into a wall of stars, which is more or less what is actually happening.

Although at first NGC 6781 may look like a spherical planetary nebula, it actually has a cylindrical shape, which has rather complex scientific implications for analyzing this object.

The red dwarf HD 260655 has two large, hot, rocky planets orbiting very close to it.
