Two incredibly strange celestial objects whose discoveries trace, in part, to observatories at the summit of Maunakea now carry the peak with them in official names inspired by Hawaiian culture.
The 235th meeting of the American Astronomical Society brought more than 3,500 scientists to Honolulu, Hawaii to unveil the latest discoveries in space and the future of astronomy. See the latest news, images and videos from the AAS 235 meeting here.
You can't rush a superdense star as it gobbles up bites of a neighbor for nearly two weeks before shooting off a burst of X-rays thousands of times brighter than our sun.
A year ago, scientists captured the unphotographable when the Event Horizon Telescope published a fiery orange ring on a black background that became instantly recognizable.
The neutron-star merger that showered the solar system with its precious metals was fairly close and fairly recent.
What could a massive new telescope in Hawaii teach astronomers about the universe — and why are some native Hawaiians fiercely opposed to the project?
Looking for life traditionally starts with finding a planet with the right temperature — but scientists are working to find new criteria for tracking down potentially habitable worlds.
NASA faces a difficult choice: What does the agency want to select as its next big space telescope, the instrument that will shape scientists' research in the 2040s?
Stars don't see gender, and now, NASA is working to not see it either when allocating telescope time to scientists, inspired by a successful experiment with the Hubble Space Telescope.
Pluto's discovery wouldn't have been possible, astronomers have realized, without the calculations of a mathematician whom history has forgotten.
Coronal mass ejections aren't known for being subtle: Each such event can fling huge amounts of the soup of charged particles called plasma off the sun and out into the solar system.
Photographing an alien world is incredibly difficult. Now try doing it from a massive balloon high in Earth's atmosphere.
NASA's New Horizons mission turned Pluto from a fuzzy blob into a detailed, geophysically complex world. But it's still a little fuzzy, as it turns out.
Move over, red dwarfs. Emerging research shows that another star type could be more friendly to life.
A tiny satellite studying alien worlds may be gone for good, but during the two years the spacecraft operated, it laid the foundation for what may become a new way of finding exoplanets.
Heated conversations at the American Astronomical Society's January meeting are usually about stars and galaxies, distant worlds and elaborate calculations.
Several supermassive black holes have been found wandering through their dwarf host galaxies, offering new clues about how similar black holes evolved in the early universe.
A new 3D movie highlights the Crab Nebula, beginning with its location in the constellation Taurus and zooming in to show off its dynamic features.
Two cosmic love birds lit the way to the discovery of dark matter, and a new Hubble image features a behemoth galaxy that played a part in the groundbreaking finding.
When scientists search for alien planets, they get a special thrill when they find one that seems to reflect our own world back to us.
