Space around the Sun contains far more than planets. Scattered through it are smaller bodies made of rock, metal, ice and ...

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have for the first time identified hydrogen sulfide gas in the atmospheres of three gas-giant exoplanets orbiting HR 8799, a ...

NASA describes deep hydrogen compression that eventually forms conductive metallic liquid, making Jupiter feel less like Earth and more like a continuous gradient of states. That alone breaks the old ...

A moon can sit next door to another and still feel like a different world. Around Jupiter, that contrast shows up fast.

INSIDE THIS REPORT The discovery did not arrive with spectacle. It arrived in spectral lines—quiet, technical, and unmistakable. NASA’s SPHEREx telescope has now detected organic molecules streaming ...

Jupiter, the largest planet in our Solar System, has just gotten a bit smaller, at least according to the latest data. New ...

New measurements show Jupiter is slightly smaller and flatter, improving models of its interior and atmosphere.

February may be the shortest month of the year, but it is packed with celestial events, according to a new skywatching update from NASA.

According to the new data, Jupiter's radius measures 71,488 kilometers (44,421 miles) at its equator, and the planet rises 66,842 kilometers from its center to its north pole. That makes it 4 ...

The photo was captured on Feb. 11, as SpaceX's Crew-12 Dragon spacecraft "Freedom" and its Falcon 9 rocket (closest to the camera) sat on the pad at Space Launch Complex 40, ready to transport a ...

The James Webb Space Telescope has detected the first-ever spectral signature of hydrogen sulfide around a massive gas giant planet.
