George's Random Astronomical Object

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.

The very small Pyxis Cluster orbits the Milky Way in such an extremely extended orbit that it travels further away than many of the dwarf galaxies orbiting our galaxy.

The NGC 6221/NGC 6215 Group of galaxies contains a bridge-like structure of hydrogen gas connecting the two spiral galaxies within the group as well as a dwarf galaxy that looks like it formed within the bridge.

The open cluster NGC 188 is peculiar not only because it is very old for an open cluster but also because it contains an unusual number of blue stars for a cluster of its age.

HD 181433 has three exoplanets, two of which are gas giants with very unusually elongated orbits that have been very challenging to properly measure.

HR 1099 (also known as V711 Tauri) was instrumental in showing that magnetic fields play a major role in causing the variability of stars within the RS CVn class of variable star systems.

Most people would associate Castor with Pollux, which are the two brightest stars in the constellation Gemini, but Castor by itself is very interesting because it is actually a very complex system containing six stars.

The quasar QSO 1331+170 is best known for having a darker galaxy in front of it that is absorbing its light.

The cluster of galaxies MACS J1149.5+2223 is so massive that it has gravitationally bent (or lensed) the light from multiple things behind it, including one of the most distant galaxies in the universe and a supernova.

NGC 34 (also known as NGC 17) is a chaotic-looking galaxy that formed from two smaller galaxies merging together, and it is a place where astronomers have easily found lots of stars forming in a starburst but where they have had difficulty concluding whether the galaxy also contains a supermassive black hole.

The Monogem Ring, which is one of the largest sources of X-rays in the Earth's sky, was created by a supernova explosion about 86000 years ago, and the core of the star that exploded has been identified as the pulsar PSR B0656+14 at the center of the ring.

Even though Alpha Mensae is in one of the faintest and dumbest constellations in the sky, it's an intriguing star system because it is very close to the Earth, because one of the stars is very Sun-like, and because it may contain an exoplanet or a disk of dust in orbit around that Sun-like star.
