Object 131: Get To Know Your Ultrafaint Neighbors

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.
