A new analysis of decades’ worth of observations has revealed that Uranus does indeed emit more heat than it receives from the rays of the Sun. This conclusion, arrived at by two independent teams of scientists, finally resolves a puzzle that first emerged when Voyager 2 cruised past the stinky planet all the way back in 1986. Those observations

Perseverance is hitting the ‘open road’ on Mars like no other rover. On June 19, the six-wheeled explorer officially completed the longest road trip of any robot vehicle on another planet. In a single drive, the rover rolled over 411 meters of Mars‘ rocky surface (more than a quarter mile).That may not sound like much, but compared to Curiosity and Opportunity, which

New images from the JWST are about as close as we’ve ever come to seeing the sky of an alien world outside the Solar System. Direct images of a gas giant exoplanet orbiting a star called YSES-1 have revealed clouds of fine sand drifting high up in its atmosphere. What’s more, similar observations of a

This week brings the Hubble Space Telescope’s 35th birthday – but instead of getting presents, the Hubble team is giving out presents in the form of four views of the cosmos, ranging from a glimpse of Mars to a glittering picture of a far-out galaxy.It’s the latest observance of a tradition that goes back decades, in which

Every now and then, robots on the surface of Mars, or the spacecraft orbiting the planet, send back some fascinating images of rock formations on the Red Planet. These can range from the interesting (such as the donut-shaped rock that may not be from the planet) to the silly (hello, avocado rock. What’s up, big pile of “bones” on Mars?).

For decades, a scattering of ruins in southeastern Europe was dismissed as little more than an unremarkable military outpost, but new excavations are rewriting that story. Archaeologists now believe the site may be the lost capital of an ancient kingdom with direct ties to none other than Alexander the Great, the ferocious conqueror whose campaigns

One of the most spectacular galaxies in Earth’s sky is the subject of a new image release to help celebrate 35 years of Hubble operations. The Sombrero Galaxy (Messier 104), located some 31 million light-years away in the direction of the constellation Virgo, is a strange galaxy, oriented in such a way that it appears even stranger
