The "lithium problem" has been a quandary for astronomers for decades, but now, with the help of one of the world's most powerful observatories, we've discovered that the puzzle isn't exclusive to stars inside the Milky Way. Continue reading →
A swarm of twinkling old stars on the outskirts of the Milky Way shines in a new view from NASA's Hubble Space Telescope.
Where did these 30,000 light-year high bubbles come from? Astronomers still aren't quite sure. Continue reading →

The boundaries of our home galaxy may have to be redrawn.
Red dwarf stars -- the most common stars in the galaxy -- bathe planets in their habitable zones with potentially deadly stellar winds, a finding that could have significant impacts on the prevalence of life beyond Earth, new research shows.
Although we have a pretty good idea that our galaxy contains a supermassive black hole at its core, there could be another — albeit rather exotic — explanation for our observations of Sagittarius A*. It might be a wormhole. This … Continue reading →
Around 7,500 light-years from Earth, in the constellation of Carina (The Keel), lies a loosely-bound collection of stars that are as beautiful as they are useful. Continue reading →
