   20 Nov 00:00:04  |  Universe Today

If you asked someone who was reasonably scientifically literate how Earth got its water, they’d likely tell you it came from asteroids?or maybe comets and planetesimals, too?that crashed into our planet in its early days. There’s detail, nuance, and uncertainty around that idea, but it’s widely believed to be the most likely reason that Earth …

Fast radio bursts are some of the most mysterious events known in astronomy, but they are slowly becoming better understood. Case in point: recent observations of a fast radio burst in the Milky Way reveals the powerhouse behind the blasts: a flaring magnetar. In 2007 astronomers first detected strange bursts of intense radio energy, known …

The family tree of the Milky Way. The mergers that gave us the galaxy we see today

   18 Nov 00:00:12  |  Universe Today

Galaxies build themselves up slowly over time by cannibalizing their neighbors. Using an advanced suite of computer simulations, researchers have now traced back the evolutionary history of our own Milky Way. Our galaxy, the Milky Way, currently hosts hundreds of billions of stars, and is pretty respectably sized for the kind of galaxy it is. …
