All stars, including the Sun, have a finite lifetime. Stars shine by the process of nuclear fusion in which lighter atoms, such as hydrogen, fuse together to create heavier ones. This process releases vast quantities of energy which counteracts the … Read More
Just over 300 light-years away is a star that’s a lot like a very young version of our Sun, with multiple exoplanets orbiting it. That’s an interesting find in itself. But what makes the system truly dazzling is that it … Read More

J1407b, a young exoplanet, has a massive ring system that is much heavier and 200 times larger than Saturn’s rings. Astronomers discovered the giant planet, which could be a brown dwarf (a failed star), when it eclipsed J1407, a very … Read More
An exoplanet only 100 light-years from Earth appears to be the best candidate yet for a sloshy, water-covered ocean world. It’s known as TOI-1452b, and measurements of its size and mass indicate a density profile consistent with a global liquid … Read More
The unusual world is among the first targets studied by the new space observatory. Astronomers have released the first image of an exoplanet captured by JWST, and it shows a strange new world. The groundbreaking telescope is said to have … Read More
