In Some Places, Black Holes are Tearing Apart Thousands of Stars at a Time
At the heart of the more massive galaxies in the Universe, there are supermassive black holes (SMBHs) so powerful that they outshine all of the stars in their galactic disks. The core regions of these galaxies are known as Active Galactic Nuclei (AGN), or by their more popular-moniker “quasars.” The ongoing study of these objects has provided a testbed for General Relativity and revealed a great deal about the formation and evolution of galaxies and the large-scale structure of the Universe.

All Five of Life's Informational Components can Form in Space
On Earth, all life comes down to the polymeric molecules known as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). These two building blocks contain all of the instructions for every living organism and its many operations. In turn, these are made up of five informational components (nucleobases), which are composed of organic molecules (purines and pyrimidines). For decades, scientists have been scouring meteorite samples for these building blocks.

Hubble has Characterized 25 Hot Jupiters. Here’s What we Know so far
Hot Jupiters are giant exoplanets – even more massive than Jupiter – but they orbit closer to their star than Mercury. When they were first discovered, hot Jupiters were considered oddballs, since we don’t have anything like them in our own Solar System. But they appear to be common in our galaxy. As exoplanets go, they are fairly easy to detect, but because we don’t have up-close experience with them, there are still many unknowns.
