Daily Telescope: A stunning new image of Io reveals a volcanic plume
Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’re going to take a different route, finding inspiration from very real images of a…

Juno discovers salts and organic compounds on Ganymede’s surface
After a flyby of Jupiter’s largest moon, Ganymede, in 2021, Juno and a team of scientists have discovered the presence of mineral salts and organic compounds on the surface of the icy moon. The new findings will allow scientists to better understand where Ganymede came from and the composition of its deep subsurface ocean. For…

Using Webb, scientists measure high-speed jet stream in Jupiter’s atmosphere
Scientists recently discovered a high-speed jet stream at Jupiter’s equator using the joint NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope. Webb’s images helped the team of scientists track fine details through the planet’s atmosphere, allowing them to measure these winds for the first time. The newly discovered jet stream will provide scientists with…

A year from launch, the Europa Clipper spacecraft nears finish line
KENNEDY SPACE CENTER, Fla.—The launch window for one of the most expensive robotic space missions in NASA’s history opens one year from Tuesday. Coming in at $5 billion, Europa Clipper will try to help scientists answer a bold question commensurate with its eye-popping cost: Are there places below the surface of Jupiter’s icy moon, Europa,…

Lucy completes its first Earth gravity assist after a year in space
A year after its launch, NASA’s Jupiter Trojan asteroid explorer Lucy has completed its first of multiple Earth gravity assists on its journey to explore nine asteroids. Lucy is a first-of-its-kind mission to visit several Trojan asteroids in Jupiter’s L4 and L5 Lagrange points. The mission’s closest approach to Earth occurred on Oct. 16 at…
