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 ...
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 ...
Stars and galaxies form by the gravitational collapse of giant clouds of gas – mostly hydrogen and helium. The first stars formed maybe a few hundred million years after the Big Bang, and the peak of star formation occurred after 3 or 4 billion years. Galaxies are giant collections of stars and dark matter. Less than 10% of all the baryons (protons, neutrons, electrons — the kind of matter ...

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.

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.
NASA's Kepler mission has made the first unambiguous detection of a circumbinary planet -- a planet orbiting two stars -- 200 light-years from Earth. Unlike Star Wars' Tatooine, the planet is cold, gaseous and not thought to harbor life, but its discovery demonstrates the diversity of planets in our galaxy. Previous research has hinted at the ...
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 ...
The focus of the new study is an event called AT2021ehb, which took place in a galaxy with a central black hole about 10 million times the mass of our Sun (about the difference between a bowling ball and the Titanic).
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
