NASA’s Hubble studied 37 nearby dwarf galaxies and found that much of the oxygen they expected to see is missing.
NASA issued a Request for Information Oct. 29 to learn more about industry capabilities for in-space servicing to support the agency’s Hubble Space Telescope.
Like a spectral form rising out of a cold mist, NASA’s Hubble and James Webb Space Telescopes have captured a hauntingly dynamic star-forming scene. It lies within the vast Carina Nebula, a diffuse star-forming region located about 7,500 light-years away from Earth. The small, select area both telescopes observed is nicknamed the Cat’s Head Nebula […]
NASA’s Neil Gehrels Swift Observatory has ended its science mission now that the spacecraft is orbiting less than 171 miles (275 kilometers) above Earth’s surface. The greater atmospheric drag at this height prevents the satellite’s telescopes from steadily gazing at their astronomical targets. Swift conducted its final observation on Oct. 20. It is expected to […]
This observation is one of many gravitational lensing images taken by Hubble in preparation for science with the new Nancy Grace Roman Space Telescope.
This NASA Hubble Space Telescope image features the edge-on, intermediate spiral galaxy NGC 1827, located roughly 37 million light-years away in the constellation Columba, the Dove.
A phenomenon rarer than a solar eclipse and more powerful than any single storm system is unfolding this fall, and NASA is tracking it closely. El Niño is a natural climate pattern that emerges roughly every two to seven years marked by warmer-than-normal water temperatures in parts of the equatorial Pacific. NASA scientists are keeping […]
First discovered in 2007, fast radio bursts are enigmatic, millisecond-long flashes of radio emission from the distant universe. Their origin remains uncertain, particularly since most are seen once and never again. Astronomers using NASA’s James Webb Space Telescope have pinpointed the host galaxy of the most distant fast radio burst (FRB) seen to date. Their […]
NASA has taken the next step in the process of developing a new all-glass telescope for the LISA (Laser Interferometer Space Antenna) mission, a space observatory designed to detect ripples in space-time called gravitational waves. L3Harris Technologies will design, assemble, and integrate the new telescope for NASA. Called the Engineering Test Unit, this contribution represents […]
New analysis of archival Hubble data points to the possibility of “dead” white dwarf stars hosting second-generation planetary systems.
In the early history of our solar system, scientists theorize that a Mars-sized object called Theia smashed into the infant Earth, vaporizing massive amounts of rock and blasting it into space. Some of that material coalesced into the Moon, where NASA’s Artemis program is returning humans, preparing for Mars, and shaping the future of space […]
NASA has awarded a contract to Omitron Inc. for the acquisition of orbital safety analysis services, which provide for critical protection of NASA spaceflight assets and astronaut lives. This indefinite-delivery contract is valued at approximately $23.5 million over a five-year period of performance and entails conjunction assessment screening services for all NASA uncrewed spacecraft, support […]
A new map of the terrain beneath the Greenland Ice Sheet links hundreds of valleys that previous maps missed or left fragmented.
NASA announced Wednesday a mission to explore the history and evolution of the universe, PRIMA (PRobe far-Infrared Mission for Astrophysics), is advancing to the next phase of development. This space telescope is the first in a new class of NASA astrophysics missions, called Probe Explorers, within the agency’s longstanding Explorers Program. “The PRIMA mission is […]
NASA’s Hubble Space Telescope completed its 200,000th orbit around Earth on Sept. 19, marking another new milestone for an observatory that continues to transform our understanding of the universe. Hubble has traveled more than 5 billion miles around Earth over its 36-year lifetime, exceeding 1.7 million total observations. An observation completed on the day of […]
Using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory, astronomers have directly observed a giant star’s outflow, called a stellar wind, being captured by its compact companion and providing the power source for strong X-ray flares. The research is part of NASA’s exploration of the extreme universe to better understand how the […]
Though the spiral galaxy in this new image from the NASA/ESA Hubble Space Telescope seems serene, it hides a chaotic secret. This galaxy is NGC 4698, and it lies about 55 million light-years away in the constellation Virgo. It’s one of over a thousand galaxies in the Virgo Cluster, the nearest large cluster of galaxies bound together by […]
NASA celebrated the full restoration of its Guam Remote Station with a ribbon-cutting on Sept. 10, closing out more than three years of recovery after Super Typhoon Mawar devastated the site in 2023. Engineers from across the agency completed the final and most complex step of the rebuild on July 1, when they returned the […]
It started as a routine data-quality check. But as Robert Wagner, a scientist with NASA’s Lunar Reconnaissance Orbiter (LRO), scanned a giant Moon map on his computer screen, an unusually large bright spot circled by a dark halo caught his eye, as it implied that surface material in that area had been shaken up. “I […]
