For the first time ever, the James Webb Space Telescope has discovered an exoplanet by directly imaging it. The newfound world has a mass roughly similar to Saturn and orbits inside the debris disk surrounding a young star named TWA 7, researchers report June 25 in Nature.
JWST has previously discovered more than 100 planets, mostly through the transit method, in which the telescope watches an exoplanet pass in front of its parent star, causing a brief dimming in the star’s light. Direct imaging — capturing a photo of a star-orbiting exoplanet — is a far more challenging task. More

Things may be moving on Venus’ surface.
In 1983, researchers discovered that the planet’s surface was speckled with strange, circular landforms. These rounded mountain belts, known as coronae, have no known Earthly counterparts, and they’ve remained enigmatic for decades. But hot plumes of rock upwelling from Venus’ mantle are shaping the mysterious landforms, a new analysis suggests. If true, that mean that Venus’ surface is tectonically active, and not merely a stagnant layer, researchers report May 14 in Science Advances. More
As the Mars rover Perseverance crested the top of Witch Hazel Hill, its operators back on Earth expected amazing things. This area on the western rim of the Jezero crater, along an ancient river delta that Perseverance has been exploring since it landed in 2021, is thought to contain some of the oldest rocks on the planet’s surface. The light-toned, layered materials promise a record of a wetter time, possibly one that hosted life.
The team did not expect what they found on March 11: a dark rock resembling a clutch of frog’s eggs. Dubbed St. Paul’s Bay, the rock looks nothing like its neighbors. Where it came from and how it formed are a mystery. More
