This image, a composite of x-ray, infrared, and optical data, shows the most massive galaxy cluster ever discovered at its distance: a staggering 9.6 billion light-years away, altogether containing the equivalent mass of 400 trillion suns. 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 "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 →
One of the most enduring mysteries behind the dynamics of supermassive black holes, and their impacts on galactic evolution, has been uncovered by an international team of astrophysicists. Continue reading →
Astronomers are studying the feeding habits of a cosmic cannibal to learn how galaxies grow.
The complex violence of a galactic cluster four-way has been recorded 5 billion light-years distant and astronomers don't yet fully understand what they are witnessing. Continue reading →
