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.

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.
