Stargazers have three reasons to look up this April as a potentially bright comet visits Earth, the Lyrid meteor shower lights up the sky, and Mercury shines at its best all year. NASA says these celestial events are all visible without special equipment, though binoculars help.
A spacecraft heading to Jupiter perfectly positioned itself to film our solar system's third interstellar visitor, giving scientists an unprecedented view of a comet from another star system. Teams across the globe collaborated on this unexpected cosmic opportunity.
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.
An interstellar visitor is leaving our solar system forever, but NASA's free public data will keep unlocking discoveries for decades. Over a dozen spacecraft captured comet 3I/ATLAS, creating a treasure trove anyone can explore.
A visitor from beyond our solar system is leaving behind a treasure trove of scientific data that anyone can access for free. NASA tracked interstellar comet 3I/ATLAS with more than a dozen missions, and every observation is now publicly available to power tomorrow's discoveries.
Scientists finally cracked a climate puzzle buried in Greenland ice for over 12,000 years, and the answer reveals how powerful Earth's own forces can be. What researchers once thought was evidence of a comet strike turns out to be something closer to home.
NASA's Hubble Space Telescope accidentally witnessed a comet fragmenting into four pieces, capturing an incredibly rare cosmic event that scientists had been trying to observe for years. The lucky discovery is revealing ancient secrets about how our solar system formed.
The legendary AFL commentator who turned football moments into poetry with phrases like "centimetre perfect" has died, leaving behind 50 years of joy for millions of fans. His gift wasn't just calling games—it was making every backyard footballer feel like their dreams had a soundtrack.
A mysterious visitor from beyond our solar system has been captured on camera by a Jupiter-bound spacecraft, giving scientists a rare glimpse into the cosmos beyond our neighborhood. Only three interstellar objects have ever been spotted passing through our solar system.
Researchers have designed a daring spacecraft mission that could catch up with an interstellar comet traveling through our solar system by using the sun's gravity as a cosmic slingshot. If launched in 2035, the mission would reach Comet 3I/ATLAS by 2085, traveling farther and faster than any spacecraft in history.
A rare visitor from beyond our solar system just gave scientists an incredible parting gift. As interstellar comet 3I/ATLAS exits our cosmic neighborhood, it's spraying ancient materials into space that haven't seen sunlight in billions of years.
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.
A comet from another star system sprayed organic molecules past Earth in December, giving scientists a rare glimpse at the chemistry that could seed life across the universe. NASA's SPHEREx telescope captured the ancient visitor releasing methanol, cyanide, and methane as it warmed near our sun.
Scientists discovered Earth's core contains enough hydrogen to equal 45 oceans of water, suggesting our planet formed with water already inside rather than getting it from comets. This breakthrough helps solve the mystery of where Earth's water really came from.
Astronomers tracked a rare visitor from beyond our solar system as comet 3I/ATLAS passed through on a one-way journey. The James Webb Space Telescope revealed its unique composition, offering scientists an exciting glimpse into how other star systems form planets.
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 planet-hunting spacecraft just captured something extraordinary: a visitor from beyond our solar system making its final journey past Earth. The comet is only the third confirmed object ever detected from another star system.
NASA's planet-hunting spacecraft caught rare footage of an interstellar comet racing through our solar system, giving scientists a precious glimpse of a visitor from beyond. The 28-hour video reveals secrets about this cosmic traveler's path back to deep space.
NASA's James Webb Space Telescope just answered a puzzle that has stumped astronomers for decades: how do frozen comets billions of miles from the sun contain crystals that need scorching heat to form? The answer reveals a cosmic delivery system more spectacular than anyone imagined.
Amateur astronomers with smart telescopes are joining NASA missions to track dangerous asteroids and discover comets. One citizen scientist in South Africa captured crucial data during NASA's asteroid deflection test.
