The nearby star DENIS J104814.7-395606 is cool (in the sense that it is awesome) because it is so cool (in the sense that it has a very low surface temperature for a star).

PSR 0820+02 is the second pulsar ever discovered to be in a binary star system.

A number of peculiarities about the lenticular galaxy NGC 5102 indicate that a dwarf galaxy fell into it several hundred million years ago.

NGC 55 has the interesting distinction of being the closest galaxy to Earth that is seen edge-on, and it also contains an ultraminous X-ray source (ULX) uncreatively named NGC 55 ULX.

NGC 281, which is also called the Pacman Nebula, is a place where star formation has been triggered two different ways, although the stars are not chased by any Ghost Nebulae.

Even though it may be rather ordinary from a scientific standpoint, the open cluster Messier 23 is a very popular with amateur astronomers.

Everything about the triple star system V505 Sgr looked normal aside from an abrupt change in the orbits of the stars sometime around the year 2000.

The short gamma ray burst GRB 100206A was found in a luminous infrared galaxy, which is very unusual place to find such gamma ray bursts.

4U 1957+115 is a low mass X-ray binary, a binary star system with a normal star about the size of the Sun and a relatively small black hole three times the mass of the Sun, and it also has an unfortunately confusing name.

The extremely bright, point-like emission from J1955+5131 in visible light and radio waves makes it useful for matching up images from different parts of the electromagnetic spectrum as well as an interesting object in its own right.
