A new investigation with NASA’s James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. Webb’s discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the...

Scientists have been working on models of planet formation since before we knew exoplanets existed. Originally guided by the properties of the planets in our Solar System, these models turned out to be remarkably good at also accounting for exoplanets without an equivalent in our Solar System, like super Earths and hot Neptunes....

Nice visual breakdown of the estimated content of the universe from Visual Capital’s website.

The Air Force and the FAA denied permission for Varda Space’s capsule to return and land on Earth....

The Keck II telescope in Hawaii is the first to see the infrared glow on Uranus, caused by hydrogen molecules in the atmosphere becoming excited.

The annular solar eclipse will be visible across North, Central, and South America on October 14. It’s the last one for the U.S. until 2039.

Giant black holes were supposed to be bit players in the early cosmic story. But recent James Webb Space Telescope observations are finding an unexpected abundance of the beasts.

While rovers have made incredible discoveries, their wheels can hold them back, and erratic terrain can mean damage. There is no replacing something like Perseverance, but sometimes rovers could use a leg up, and they could get that from a small swarm of four-legged robots.

Jupiter-sized “planets” free-floating in space, unconnected to any star, have been spotted by the James Webb Space Telescope (JWST).
