12 janv. 2021 · Stars and Galaxies Research at JPL. The nighttime sky is magical. The dark curtain sprinkled with tiny dots of light has inspired songs, sparked romances, and prompted humans through the ages to gaze at the twinkling scene overhead and wonder what’s out there and what it all means. Some of those humans are scientists and engineers at JPL, who ...
12 juil. 2022 · July 12, 2022. One of the first images captured by the James Webb Space Telescope, this landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby young star-forming region called NGC 3324 in the Carina Nebula.

5 nov. 2024 · JPL is a federally funded research and development center managed for NASA by Caltech. Space mission and science news, images and videos from NASA's Jet Propulsion Laboratory, the leading center for robotic exploration of the solar system.
12 juil. 2023 · Some stars in the image display telltale shadows indicating protoplanetary disks – potential future planetary systems in the making. A Full Year, Across the Full Sky From its very first deep field image , unveiled by President Joe Biden, Vice President Kamala Harris, and Nelson live at the White House, Webb has delivered on its promise to show us more of the universe than ever before.

14 févr. 2024 · The burst occurred between two “glitches,” when the magnetar suddenly started spinning faster. SGR 1935+2154 is estimated to be about 12 miles (20 kilometers) across and spinning about 3.2 times per second, meaning its surface was moving at about 7,000 mph (11,000 kph
13 juin 2024 · NASA’s Webb Reveals Long-Studied Star Is Actually Twins. June 13, 2024. Managed by NASA’s Jet Propulsion Laboratory through launch, Webb’s Mid-Infrared Instrument also revealed jets of gas flowing into space from the twin stars. Scientists recently got a big surprise from NASA’s James Webb Space Telescope when they turned the ...
5 janv. 2017 · Since other galaxies are extremely far away, there's no tape measure long enough to measure their distances from us. Instead, astronomers rely on extremely bright objects, such as Type Ia supernovae and pulsating stars called Cepheids variables, as indicators of distance. To calculate how far away a distant galaxy is, scientists use known ...
23 mai 2024 · Euclid’s large-area sky map can, for instance, be used to discover faint objects and observe changes in cosmic objects, like a star changing in brightness. Euclid’s new science results include the detection of free-floating planets (planets that don’t orbit stars), which are difficult to find because of their faintness. In addition, the ...
15 août 2024 · Most familiar stars peacefully orbit the center of the Milky Way. But citizen scientists working on NASA’s Backyard Worlds: Planet 9 project have helped discover an object moving so fast that it will escape the Milky Way’s gravity and shoot into intergalactic space. This hypervelocity object is the first such object found with the mass of a ...
