The center of the barred spiral galaxy Messier 71 contains multiple regions where stars are forming as well as an inactive supermassive black home that needs some caffeine.

Eta Aquilae was the first Cepheid variable ever discovered, but this class of stars was named after Delta Cephei instead.

The North Ecliptical Pole points to a location perpendicular to the plane of the Solar System, which makes it a unique place for certain types of astronomical observations.

The spiral galaxy NGC 6814 is a source of strong but variable X-ray emission that astronomers are using to measure the mass of a supermassive black hole at its center.

The abnormal-looking globular cluster Messier 71 is unusual in that its stars contain an excessive amount of heavy elements and in that it is being gravitationally shredded by the Milky Way.

The binary star system b Centauri contains an exoplanet named b Centauri b that, despite its confusing name, has changed astronomers' perspectives on how and where planets can form.

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.
