These simulated views of the ultrahot Jupiter WASP-121b show what the planet might look like to the human eye from five different vantage points, illuminated to different degrees by its parent star. The images were created using a computer simulation being used to help scientists understand the atmospheres of these ultra-hot planets. Ultrahot Jupiters reflect almost no light, rather like charcoal. However, the daysides of ultrahot Jupiters have temperatures of between 3600°F and 5400°F (2000°C and 3000°C), so the planets produce their own glow, like a hot ember. The orange color in this simulated image is thus from the planet's own heat. The computer model was based on observations of WASP-121b conducted using NASA's Spitzer and Hubble space telescopes.

Water Is Destroyed, Then Reborn in Ultrahot Jupiters

Water Is Destroyed, Then Reborn in Ultrahot Jupiters Imagine a place where the weather forecast is always the same: scorching temperatures, relentlessly sunny, and with absolutely zero chance of rain. This hellish scenario exists on the permanent daysides of a type of planet found outside our solar system dubbed an…

Radiation from Jupiter can destroy molecules on Europa’s surface. Material from Europa’s ocean that ends up on the surface will be bombarded by radiation, possibly destroying any biosignatures, or chemical signs that could imply the presence of life. Credits: NASA/JPL-Caltech

Radiation Maps of Jupiter’s Moon Europa: Key to Future Missions

Radiation Maps of Jupiter’s Moon Europa: Key to Future Missions New comprehensive mapping of the radiation pummeling Jupiter’s icy moon Europa reveals where scientists should look — and how deep they’ll have to go — when searching for signs of habitability and biosignatures. Since NASA’s Galileo mission yielded strong evidence…

During its continued mission, NASA’s Juno spacecraft will maintain its 53-day polar orbit around Jupiter. At its closest, Juno passes within 3,000 miles (5,000 kilometers) of Jupiter’s cloud tops once during each 53-day orbit. At the high end of each orbit, Juno is about 5 million miles (8-million kilometers) from the planet – which is just beyond the orbit of the Jovian moon Themisto. Credits: NASA/JPL-Caltech

NASA Re-plans Juno’s Jupiter Mission

NASA Re-plans Juno’s Jupiter Mission NASA has approved an update to Juno’s science operations until July 2021. This provides for an additional 41 months in orbit around Jupiter and will enable Juno to achieve its primary science objectives. Juno is in 53-day orbits rather than 14-day orbits as initially planned…

Juno Solves 39-Year Old Mystery of Jupiter Lightning

Juno Solves 39-Year Old Mystery of Jupiter Lightning Ever since NASA’s Voyager 1 spacecraft flew past Jupiter in March, 1979, scientists have wondered about the origin of Jupiter’s lightning. That encounter confirmed the existence of Jovian lightning, which had been theorized for centuries. But when the venerable explorer hurtled by,…

Artist’s illustration of Jupiter and Europa (in the foreground) with the Galileo spacecraft after its pass through a plume erupting from Europa’s surface. A new computer simulation gives us an idea of how the magnetic field interacted with a plume. The magnetic field lines (depicted in blue) show how the plume interacts with the ambient flow of Jovian plasma. The red colors on the lines show more dense areas of plasma.
