In 2011, astronomers were getting excited for what promised to be a spectacular cosmic event. Sadly, it looks like it's turned out to be a galactic damp squib. 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 →
How do magnetars become so magnetized? Astronomers think that they might get a little help from their friends. Continue reading →
Astronomers have long been in the dark about what is happening just beyond the center of the Milky Way -- but with the help Cepheid variable stars, we're beginning to realize that our galaxy's outer disk is mysteriously flared.
When two galaxies collide, the mingling interstellar gases are violently turbulent. Turbulence should switch off any star formation, but galactic mergers are known to be fertile grounds for stellar birthing -- what's going on? Continue reading →
