H1821+643 is a quasar powered by a supermassive black hole, located about 3.4 billion light years from Earth. Astronomers used NASA’s Chandra X-ray Observatory to determine the spin of the black hole in H1821+643, making it the most massive one to have an accurate measurement of this fundamental property, as described in our press release. Astronomers…

In just minutes, a flare on the Sun can release enough energy to power the whole world for 20,000 years. An explosive process called magnetic reconnection triggers these solar flares and scientists have spent the last half-century trying to understand how the process happens. It’s not just a scientific curiosity:…

Two enormous galaxies capture your attention in this spectacular image taken with the NASA/ESA Hubble Space Telescope using the Wide Field Camera 3 (WFC3). The galaxy on the left is a lenticular galaxy, named 2MASX J03193743+4137580. The side-on spiral galaxy on the right is more simply named UGC 2665. Both galaxies lie…

A spectacular set of rings around a black hole has been captured using NASA’s Chandra X-ray Observatory and Neil Gehrels Swift Observatory. The X-ray images of the giant rings have revealed new information about dust located in our Galaxy, using a similar principle to the X-rays performed in doctor’s offices…

This image, taken with the NASA/ESA Hubble Space Telescope, depicts a special class of star-forming nursery known as Free-floating Evaporating Gaseous Globules, or frEGGs for short. This object is formally known as J025157.5+600606. When a massive new star starts to shine while still within the cool molecular gas cloud from which it formed,…
