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 →
Quasars are the brightest objects in the universe, and display a mysterious diversity in their appearance that has puzzled astronomers for more than two decades.
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 →
Using a new mapping technique that takes into account the motions -- and not just the distances -- of nearby galaxies, astronomers discovered that the Milky Way is located in the suburb of a massive, previously unknown super-cluster they named Laniakea.
The space telescope has zoomed in on a galactic pair that are gravitationally disturbing one another's stellar populations. Continue reading →
Chemical signature of ancient star suggests it incorporated material blasted into space by a supernova explosion from huge star in early universe.
A recent discovery of an intermediate-mass black hole in a nearby galaxy offers the best evidence yet that a class of medium-size black holes exists.
