Stars and Galaxies | NASA Jet Propulsion Laboratory (JPL)
2021年1月12日 · Galaxies that merge into giant swirls. Enormous stars that eventually explode and become supernovas. Neutron stars — objects so dense, one tablespoon of their material would weigh about 1 billion tons on Earth. Through its research and missions, JPL has captured data and stunning images of many of these odd objects in space.
NASA Eyes Launching SPHEREx Sky-Mapping Mission in Early 2025
2024年12月9日 · Led by Southwest Research Institute’s office in Boulder, Colorado, and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, PUNCH is a constellation of four small satellites heading to low Earth orbit that will make global, 3D observations of the Sun’s corona to learn how the mass and energy there become solar wind.
Webb Celebrates First Year of Science With Close-up on Birth of …
2023年7月12日 · Our own Sun experienced a phase like this, long ago, and now we have the technology to see the beginning of another star’s story,” said Klaus Pontoppidan, who served as Webb project scientist at the Space Telescope Science Institute in Baltimore, Maryland, since before the telescope’s launch and through the first year of operations.
Why NASA’s SPHEREx Mission Will Make ‘Most Colorful’ Cosmic …
2024年10月31日 · Many space telescopes, including NASA’s Hubble and James Webb, can provide high-resolution, in-depth spectroscopy of individual objects or small sections of space. Other space telescopes, like NASA’s retired Wide-field Infrared Survey Explorer (WISE), were designed to take images of the whole sky. SPHEREx combines these abilities to apply ...
NASA Telescopes Find New Clues About Mysterious Deep Space …
2024年2月14日 · In October 2022, the same magnetar – called SGR 1935+2154 – produced another fast radio burst, this one studied in detail by NASA’s NICER (Neutron Star Interior Composition Explorer) on the International Space Station and NuSTAR (Nuclear Spectroscopic Telescope Array) in low Earth orbit. The telescopes observed the magnetar for hours ...
NASA Citizen Scientists Spot Object Moving 1 Million Miles Per Hour
2024年8月15日 · 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 …
Star Duo Forms ‘Fingerprint’ in Space, NASA’s Webb Finds
2022年10月12日 · A Wolf-Rayet star is an O-type star, born with at least 25 times more mass than our Sun, that is nearing the end of its life, when it will likely collapse and form a black hole. Burning hotter than in its youth, a Wolf-Rayet star generates powerful winds that push huge amounts of gas into space.
NASA Reveals Webb Telescope’s First Images of Unseen Universe
2022年7月12日 · The James Webb Space Telescope launched Dec. 25, 2021, on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, South America. After completing a complex deployment sequence in space, Webb underwent months of commissioning where its mirrors were aligned, and its instruments were calibrated to its space environment and prepared for …
Webb Finds Evidence for Neutron Star at Heart of Young …
2024年2月22日 · NASA’s James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, meaning the compacted remains at its core formed either a neutron star or a black hole.
NASA’s Webb Images Cold Exoplanet 12 Light-Years Away
2024年7月24日 · The gas-giant exoplanet Epsilon Indi Ab imaged using the MIRI instrument on NASA’s Webb telescope. A star symbol marks the location of the host star, whose light has been blocked by MIRI’s coronagraph, resulting in the dark circle with a dashed white line. The planet is to the left of the star.
