Material around Chiron, a small icy world in the far reaches of the solar system, may be taking shape into a ring system of its own. The rare event is unfolding in real time, giving astronomers a unique opportunity to witness the evolution of celestial bodies. A team of scientists from Brazil observed initial hints […]
You Need to See This Bright New Comet Shine in the Night Sky This Month Before It Disappears for 1,000 Years
This year is a boom time for comets. Not only did we have the interstellar object 3I/ATLAS gracing our skies (and Mars’) earlier this year, but now we have another brand new comet to look out for. Expected to be at its brightest on October 21, this month you might have the chance to spot […]
NASA’s Perseverance Rover Spies an Interstellar Visitor Hurtling Through the Solar System
Robots, they’re just like us—fascinated by the skies above them and the mysteries they hold. And now, NASA has revealed that its Mars Perseverance rover might have spotted a mysterious visitor from beyond our solar system. A recent photo taken by the rover on Saturday shows a bright streak of light across the Martian sky, […]
Two Newly Discovered Comets Will Streak Across the Skies This Month. Here’s How to See Them
Skywatchers, rejoice. This month, not one but two comets are set to soar into our night skies for your viewing pleasure. The two comets, C/2025 R2 (SWAN) and C/2025 A6 (Lemmon), were both discovered in 2025. The celestial visitors are gearing up for a close flyby of Earth in October, becoming more visible as they […]
This Visiting Interstellar Comet Just Keeps Getting Weirder
Ever since interstellar comet 3I/ATLAS whizzed into our cosmic neighborhood in July, astronomers have been racing to uncover its characteristics. Now that the powerful James Webb Space Telescope has taken a good look at this icy interloper, it seems to be weirder than anyone imagined. A preprint submitted to the Astrophysical Journal Letters for peer […]
New Study Fuels Debate Over World-Changing Comet Strike 12,800 Years Ago
Roughly 12,800 years ago, as Earth was emerging from its last great ice age, temperatures in the Northern Hemisphere suddenly plummeted back to near-glacial conditions. The cause of this abrupt shift—known as the Younger Dryas cool period—remains a mystery to this day, but new evidence may give credence to its most controversial explanation. Researchers analyzed […]
Only the Third Ever Detected Interstellar Object May Be Whizzing Through Our Solar System Right Now
Astronomers are scrambling to gather data on a mysterious object that’s currently hurtling through the solar system. Preliminary observations suggest it came from interstellar space, and if confirmed, it would mark the third discovery of an interstellar object in history. The cosmic visitor—tentatively named A11pl3Z—first appeared in data collected by the Asteroid Terrestrial-impact Last Alert […]
A New Comet Is Streaking Across the Morning Sky. Catch It Before the Sun Does
A recently discovered comet is currently gracing our morning skies, with its signature green glow and long tail trailing behind. Comet SWAN25F is speeding toward the Sun for a dangerously close approach, which might either destroy it or make it visible to the naked eye. In the meantime, the bright comet can be spotted with […]
