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.
