The Zwicky Transient Facility has taken its first image, covering an area equivalent to 247 full Moons in a single shot. This beginning is part of an ongoing sea change in astronomy.
Observations of a stellar explosion that refused to fade away have astronomers scratching their heads. What created the blast — and could it explain massive black holes?
Two telescopes — one on the ground and one in space — watched a black hole’s jet turn on, enabling astronomers to probe its origin.
The detection of a star-forming region 66,500 light-years from Earth, on the other side of our galaxy’s center, lends weight to the existence of an extended arm of the Milky Way.
The long-awaited James Webb Space Telescope — the successor to the Hubble Space Telescope — has slipped its launch date by several months. It will now launch between March and June 2019.
A few decades ago, astronomers thought they had figured out how quasars operate. Now, a new study has thrown a wrench in the works.
Curious about machine learning? Learn about the inner workings of machine-learning algorithms without writing a line of code.
Astronomers have found what could be the closest known pair of supermassive black holes detected via direct imaging, orbiting each other only a light-year apart.
The exoplanet-hunting Kepler satellite has long monitored thousands of stars, but the brightest ones have largely remained out of its reach — until now.
Our new-and-improved interactive sky chart is here — create and print a customized view of your night sky for any date, time, and location.
Multiple organizations are live-streaming the total solar eclipse from groundbased telescopes, racing Volvos, and high-altitude balloons — take a look!
Enrich the eclipse experience — especially the long, partial phases — with solar eclipse activities for kids and families.
Astronomers have used an innovative technique to discover four super-Earth-size planet candidates orbiting Tau Ceti, a Sun-like star 12 light-years away.
A new study finds that rogue planets — those floating free in the galaxy, unbound to any star — are not as plentiful as we once thought.
New ALMA observations reveal a forming star as it launches a wind from the edge of the disk that feeds it.
Astronomers monitoring a tight pair of supermassive black holes have observed their orbital motion.
A sparse galactic neighborhood could clear up certain problems with our understanding of the universe.
A team of astronomers has taken a close look at a nearby galaxy — and discovered an unusual structure that sheds light on supermassive black holes’ relationships with their host galaxies.
Astronomers may have watched a star collapse directly into a black hole — minus the supernova. The failed supernova could help understand how stars die.
Our galaxy's center region is producing gamma rays, but astronomers are still debating whether pulsars or dark matter are the source. Three recent studies tackle the debate head-on.
Tabby's star, otherwise known as the most mysterious star in the galaxy, is dipping drastically in brightness, giving astronomers an opportunity to figure out what has been causing this star's weird behavior.
In just a month, teams will guide this 300-pound, 6-foot-tall humanoid robot in a series of simulated trials as part of NASA’s Space Robotics Challenge.
Astronomers have detected water in the cloud-free skies of "warm Neptune" HAT-P-26b, a clue in the larger mystery of how these planets formed.
A new galaxy survey suggests that a supervoid isn’t responsible for the Cold Spot seen in the cosmic microwave background — the oddity may have a far more ancient origin.
Astronomers have discovered a gravitationally lensed Type Ia supernova that will soon give them a new measure of the universe’s expansion.
