An asteroid discovered in 1998 just revealed its true identity: a rare "dark comet" that's been fooling scientists for nearly three decades. The discovery helps protect Earth by improving how we track space objects that might come our way.
A whimsically named cosmic cloud drifting through southern skies reminds us that even professional astronomers find joy in playful naming. The Dark Doodad Nebula got its delightful name from an astronomer chasing Halley's Comet in the Australian outback nearly 40 years ago.
After bouncing across a comet and tumbling into darkness, the washing machine-sized Philae lander was finally spotted by its partner spacecraft in 2016. The discovery gave scientists closure on humanity's first-ever soft landing on a comet.
A comet that usually passes by unnoticed suddenly burst to life this summer, shining 20,000 times brighter than normal and giving stargazers an unexpected celestial treat. You still have a few weeks to spot it before it fades back into the darkness.
Scientists propose that dark matter-powered stars could explain three puzzling discoveries from the early universe, including mysterious supermassive black holes and ultra-bright galaxies that shouldn't exist. This breakthrough theory offers hope for understanding both the cosmos and dark matter itself.
A newly brightening comet could become visible to the naked eye in mid-April, offering early risers a rare celestial show. Comet PanSTARRS is expected to reach peak brightness around April 20 when it passes closest to the sun.
A rare comet could brighten enough for people to see with their naked eyes or binoculars this month, offering early risers an exciting celestial show. The comet reaches its brightest points between April 20 and 27.
A newly visible comet is gracing New Zealand skies this month, giving Kiwis a rare chance to witness a cosmic visitor. While faint now, the comet is expected to climb higher throughout May.
A spacecraft caught a comet "switching on" a second tail as it made its closest approach to Earth on April 26. The rare cosmic light show revealed how comets create stunning dual tails when approaching the sun.
Four astronauts circling the moon this week might witness a stunning comet during their historic journey. If Comet MAPS survives its close encounter with the sun, it could create an unforgettable view from their spacecraft window.
A rare green comet the size of a small city is making its final pass by Earth this week before being flung into deep space forever. Scientists say Comet Wierzchoś will spend millions of years drifting through the galaxy after its one-time visit to our cosmic neighborhood.
Astronomers discovered a rare comet that might become bright enough to see with the naked eye next spring. This comet belongs to a special family that has produced some of history's most spectacular sky shows.
NASA's James Webb Space Telescope discovered methane and unusual carbon dioxide levels in an interstellar comet passing through our solar system. The findings reveal this cosmic visitor formed under completely different conditions than our homegrown comets.
A spacecraft flying alongside a comet discovered amino acids and phosphorus streaming off its surface, the same chemical ingredients that helped create life on Earth. Scientists captured the first unambiguous proof that comets can carry and preserve these vital molecules through the solar system.
NASA's James Webb Space Telescope detected methane on a comet from another star system for the first time, revealing chemistry unlike anything we've seen before. The discovery gives scientists their first real glimpse into how alien solar systems form planets and comets.
A comet that last visited Earth during the Ice Age is putting on a brief show in pre-dawn skies through April 20. Stargazers have just days to catch this once-in-a-lifetime visitor before it disappears forever.
A comet that hasn't visited Earth in 170,000 years is lighting up predawn skies right now, and Monday offers the best chance to spot it near a crescent moon. You only need binoculars and an early alarm.
Four amateur astronomers in southern France discovered a comet heading toward the Sun 300 million kilometers away, earlier than any similar comet has been detected before. Using just four private telescopes and tracking software, they beat major space agencies to one of astronomy's most exciting finds.
Scientists have discovered that faint radio waves from the universe's "Dark Ages" could reveal the nature of dark matter. New telescopes on the Moon might finally detect this ancient signal and unlock one of astronomy's biggest mysteries.
In a cosmic stroke of luck, NASA's Hubble Space Telescope accidentally captured a comet splitting into pieces as it happened, something scientists have tried and failed to observe for years. The team was studying a completely different comet when they stumbled upon this once-in-a-lifetime view.
