A comet named 3I/ATLAS is on a long trip through our solar system. It's not from around here. It came from another star system. This is only the third time scientists have seen something like this. Some people wonder if it could be from aliens. An astronomer named John Tonry works with a system tha
A comet from another star system has been making headlines. It's called 3I/ATLAS, and it's the third such visitor we've spotted. It's not a spaceship, despite what some people might think. Scientists are still figuring out what makes this comet tick. When 3I/ATLAS got close to the sun, it started t
Gamma-ray bursts are intense flashes of energy that light up the universe. They were first spotted in the late 1960s, making them a relatively recent discovery in space science. These bursts are short-lived, lasting from a fraction of a second to a few thousand seconds. The bursts are caused by ext
A comet is zooming close to the Sun, and some people think it might be an alien spacecraft. This idea comes from a scientist named Avi Loeb, who has made similar claims before. He thinks this comet, called 3I/ATLAS, might show signs of being artificial. But most scientists disagree. Loeb has a hist
Humans have always been fascinated by the possibility of life existing beyond Earth. This fascination has driven us to look up at the stars and wonder what else might be out there. Over time, this curiosity has turned into a serious scientific mission. Scientists from different fields, like astronom
A huge asteroid, as big as a skyscraper, is zooming around our sun. It's called 2025 SC79. This space rock is one of the fastest in our solar system. It completes a full trip around the sun in just 128 days. That's super quick for an asteroid! This asteroid is special because it's one of only two k
Seven former heads of NASA's science programs have joined forces to protest a huge budget cut. They want Congress to say no to a 47% reduction in NASA's 2026 science budget. This cut could stop many space missions and hurt thousands of scientists and engineers. It could also make the U. S. fall behi
The Curiosity rover has sent back some fascinating pictures from Mars. These images show strange patterns on a mountain. Scientists think these patterns might tell us about water on Mars a long time ago. Mars is a dry, dusty place now. But it wasn't always like this. Long ago, rivers, lakes, and ma
The Hubble Space Telescope has been a game-changer in space exploration. It has been 35 years since its launch. It has captured 1. 7 million observations. The telescope has a fascinating history. It started with a rocky beginning. A mirror upgrade in 1993 was needed. Since then, it has mad
Space exploration has always been a big deal. It has expanded our knowledge and inspired countless people. However, recent budget proposals threaten to slow down this progress. The White House Office of Management and Budget suggested cutting NASA's science program by 47%. This could halt or even ca
