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. 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.
24 juin 2020 · More. Neutron stars, or cores leftover from exploded stars, are some of the densest objects in the universe. There are several types of neutron stars, shown in this illustration, including magnetars and pulsars.
NASA's Jet Propulsion Laboratory, the leading center for robotic exploration of the solar system.
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
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.

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 ...
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 ...
2 juil. 2024 · Its stars are located at a distance of about 1000 light years from us, and they formed about 200 million years ago. The cluster was discovered by Greek-Roman astronomer Ptolemy in the year 130, hence its other name. M6 is about half the apparent size of M7, and contains fewer stars. It's also a bit farther away from us, at around 1600 light ...
Once upon a space-time, a cosmic creation story unfolded: thousands of never-before-seen young stars spotted in a stellar nursery called 30 Doradus, captured by NASA’s James Webb Space Telescope. Nicknamed the Tarantula Nebula for the appearance of its dusty filaments in previous telescope images, the nebula has long been a favorite for ...
