-
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.
-
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.
-
The Type Ia supernova SN 2005cf was observed at multiple wavelengths for three months after its appearance, allowing astronomers to create templates of its spectrum that could be used to measure distances to other Type Ia supernovae.
-
Kappa Cassiopeiae is a large blue variaable star that is most potentially interesting because of the bow shock between its stellar winds and the interstellar medium.
-
While the planetary nebula NGC 1501 is a popular amateur astronomy target, the newly formed, hot, pulsating white dwarf at its center is much more interesting to professional astronomers.
-
As the second closest spiral galaxy to the Milky Way, Messier 33 has been a very popular observing target for both amateur and professional astronomers, and even I have made images of the galaxy.
