As galaxies mature, they stop forming stars -- but why? Now astronomers are hot on the trail of finding the culprit. Continue reading →
Like a bully running around the playground stealing smaller kids' lunch money, our Milky Way galaxy has been ransacking nearby dwarf galaxies, stealing their precious star-forming gases. Continue reading →
The Milky Way may be home to some 3,000 extraterrestrial civilizations but the vast distances between our galactic cousins will make contact extremely rare, a new study concludes.
There's nothing in the universe that isn't moving -- even us. Trace tries to slow things down long enough to calculate just how fast we little humans, even when seated, are flying through space.
The likelihood that a South Pole-based telescope detected elusive gravitational waves earlier this year has just taken another nosedive. Continue reading →
A surprisingly massive black hole has been discovered in the core of a small, compact galaxy -- a finding that appears to be a weird cosmic contradiction.
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 →
Approximately 10 million years ago, a nearby cluster of stars erupted as a violent series of supernovae and, according to new observations, the million degree plasma from these powerful detonations surround the solar system today. Continue reading →
