A telescope in Chile accidentally photographed an alien comet visiting from another star system ten days before astronomers officially discovered it. The find proves we're getting better at catching these rare cosmic visitors as they pass through our neighborhood.
The Rubin Observatory captured images of an interstellar visitor on its very first night of practice runs, ten days before the comet was officially discovered. Two Jupiter-bound spacecraft later teamed up to reveal this ancient traveler might be up to 12 billion years old.
Scientists discovered a comet that slowed down, stopped, and then started spinning the opposite direction after jets of gas pushed it like a cosmic merry-go-round. The discovery happened by digging through old NASA data, proving that space observations made decades ago still hold new secrets.
For the first time, astronomers watched a comet slow down, stop, and then start spinning the opposite way. The discovery reveals how dynamic and powerful these icy space wanderers really are.

A comet did something scientists have never seen: it slowed down, stopped spinning, and started rotating the opposite direction. The discovery gives us a rare chance to watch one of these ancient space rocks transform before our eyes.
NASA's James Webb Space Telescope just caught methane on an interstellar comet for the first time, revealing chemistry unlike anything in our solar system. The discovery shows this cosmic visitor carries secrets from a very different corner of the universe.
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.
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.
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.
Scientists caught a comet doing something never seen before: completely reversing its spin direction after slowing nearly to a stop. The rare cosmic flip happened in just weeks instead of the usual centuries.
The James Webb Space Telescope just detected methane on a visitor from beyond our solar system for the first time. The discovery reveals that comet 3I/ATLAS formed in a completely different cosmic neighborhood with chemistry unlike anything in our own stellar backyard.
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.
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.
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.
Scientists studying an interstellar comet passing through our solar system discovered it contains 30 times more heavy water than any comet from around our sun. The finding suggests our home solar system formed in unusually warm conditions compared to other star systems.
A comet from another star system is releasing enough water to fill 70 Olympic pools every day as it passes through our solar system. The rare visitor gives scientists their first chance to study materials from planetary systems far beyond our own.
Scientists traced an interstellar comet to one of the coldest, most isolated corners of the early galaxy, offering a rare glimpse into how our universe formed billions of years ago. The cosmic visitor, possibly 11 billion years old, just gave us a window into conditions that existed before our Sun was born.
A groundbreaking study of over 750 Nobel Prize and major discoveries reveals that new tools and methods, not just funding or theory, drive most scientific breakthroughs. The findings could help us predict and accelerate future discoveries across all fields of science.
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.
After a seven-month journey through our solar system, interstellar comet 3I/ATLAS has faded from view, leaving astronomers with treasure trove of data from one of the most-studied comets in history. The ancient visitor from another star system is now heading back into deep space, reminding us of the wonders waiting beyond our cosmic neighborhood.
