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.
Despite the variability of the gamma radiation from J0510+1800, this blazar is used as a flux calibrator at millimeter and submillimeter wavelengths.
WASP-103 has an acronym for a name and also has a gaseous planet orbiting so close to it that the planet is in danger of being destroyed.
BV Centaurus is an unusual example of a class of U Gem cataclysmic variable stars in which a white dwarf is stripping gas from a companion star.
ELAIS N1 is a extragalactic deep field selected specifically for identifying many distant, faint galaxies at infrared wavelengths.
Psi Capricorni was the first star other than the Sun where the phenomenon of differental rotation was ever measured.
Abell 85 is a large, nearby cluster of galaxies with so many things happening inside that it could be called a ball of chaos.
The star HD 214714 contains not only a large amount of carbon in its stellar atmosphere but also a peculiar combination of other heavy elements as well.
II Zw 96 is a luminous infrared galaxy (LIRG) where most of the infrared emission comes from some type of off-center region, which is weird compared to most other LIRGs.
30 Ari contains four stars and an exoplanet all arranged in a rather complex set of nested orbits.
HD 98851 is both an Am chemically peculiar star and a delta Scuti variable star, and it has two different pulsation cycles, which makes it really peculiar.
RV Octantis would be considered a run-of-the-mill RR Lyrae variable star if it wasn't for the unexpected discovery of helium in its atmosphere.
The most interesting thing about the quasar LBSQ 0058+0155 is not the quasar itself but the galaxy between the quasar and Earth.
HD 85512 is a nearby star slightly smaller and more orange than the Sun. It happens to have an exoplanet that could be close to Earth-like.
