It may not be anything like Tatooine of Star Wars, but this discovery is still incredible. We've found a frozen, rocky planet orbiting one of its two parent binary stars in a stable Earth-like orbit. This significantly expands our sense of where life can emerge in the galaxy.
When half of a binary system goes supernova, usually that means a very bad day for the remaining star. But DEM L241 is tougher than that, surviving the astronomical blast to shine another day.
A couple weeks ago, astronomers spotted black holes that were ten billion times more massive than our Sun, setting new records for the biggest black holes ever found. NASA has spotted another record-setting black hole...although it's not quite as impressive.
Over a thousand light-years from Earth, there are two white dwarfs, the ghostly remnants of stars much like our Sun. But these stars aren't ordinary white dwarfs, and their bizarre composition reveals a long, passive-aggressive history of mutually assured destruction.
White dwarfs are the ultra-dense husks of stars like our own, dying remnants that are just a pale shadow of their former glory. But when two white dwarfs come together, they can create something very special: a brand new star.
