Astronomers have made a big discovery. They found a cosmic explosion that lasted for seven hours. This is the longest gamma-ray burst ever seen. It was detected by NASA's Fermi Gamma-ray Space Telescope on July 2, 2025. The burst, named GRB 250702B, is different from others. It had repeating explosi
In the vast expanse of the cosmos, a peculiar structure has caught the eyes of astronomers. This structure, initially thought to be a stunning cosmic ring, has now been revealed to be something entirely different. Located in the constellation Cygnus, this ring, nicknamed the "Diamond Ring, " spans a
The James Webb Space Telescope (JWST) has just made a big find. It has spotted its first new planet outside our solar system. This planet, named TWA 7b, is special. It is the lightest planet ever seen directly outside our solar system. It is about 100 times the mass of Earth. That is still very ligh
The universe is full of surprises, and one of its biggest puzzles has finally been cracked. For a long time, scientists have known that ordinary matter, the stuff we can see and touch, makes up only a small part of the universe. But where is the rest of it? This question has baffled astronomers for
The future of our galaxy, the Milky Way, might not be as dramatic as once thought. The Milky Way and Andromeda are on a path to meet. This has been known for some time. However, scientists are now saying it is equally likely that they will miss each other. This is a significant change from prev
Astronomers have found something amazing. There is a giant cloud of gas and dust near our solar system. This cloud is called Eos. It is huge. It is so big that it looks like 40 full moons in the sky. This cloud is made mostly of molecular hydrogen. This is the stuff that makes stars and planet
The solar system might have a ninth planet. It is hiding far beyond Neptune. Scientists have been looking for it for years. They have not seen it yet. The evidence comes from strange orbits of small, icy bodies. These orbits suggest a large planet is pulling them with its gravity. A powerful telesc
Saturn, the ringed wonder of our solar system, just got a whole lot more interesting. Scientists have just announced the discovery of 128 new moons orbiting the gas giant. This isn't just a big deal for Saturn—it's a big deal for our whole understanding of the solar system. These new moons are tiny
Imagine planets so hot that they make Earth seem like a cold winter day. These are the ultra-hot Jupiters, a special group of exoplanets that have scientists buzzing with excitement. Why? Because they offer a unique glimpse into the wild weather patterns that can happen in space. Over 5, 800 exopla
