Even though HD 106252 has an exoplanet orbiting it, astronomers are much more interested in the fact that HD 106252 looks very similar to the Sun.

VER J0521+211 is a distant galaxy that produces gamma rays with such high energy that, when the gamma rays hit the Earth's atmosphere, the photons transform into electrons and positrons.

UX Ari is an RS CVn type variable star system, which is a confusing way to classify variable star systems but which means that UX Ari contains two stars very close together with complex, interacting magnetic fields that produce all sorts of weird effects.

NGC 7457 was one of the first things imaged by the Hubble Space Telescope, which meant that the images of it were relatively blurry, but this is not the most interesting fact about this lenticular galaxy.

SPT-CL J0546-5345 is an abnormally large cluster that formed very quickly after the Big Bang, which places some strong constraints of models of the formation and evolution of the universe.

UM 425 could be either a pair of very similar quasars at the same distance from Earth or a single quasar that has been gravitationally lensed so that it appears twice in the sky.

VW Cephei is an eclipsing binary star system containing two stars that are so close that they share an outer gas layer.

Chi Cygni is a Mira-type variable star with some of the most extreme variations in brightness among any variable stars in the sky.

3C 147 is not the first object ever identified as a quasar, but it is sort of one of the first two objects ever called a quasar.

Astronomers may not have found an exoplanet orbiting the star HD 191089, but they found the next best thing.
