NASA’s Fermi Spots Young Star Cluster Blowing Gamma-Ray Bubbles

For the first time, astronomers using NASA’s Fermi Gamma-ray Space Telescope have traced a budding outflow of gas from a cluster of young stars in our galaxy — insights that help us understand how the universe has evolved as NASA explores the secrets of the cosmos for the benefit of all. The cluster, called Westerlund […]

NASA IXPE’s Longest Observation Solves Black Hole Jets Mystery

Written by Michael Allen An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) has identified the origin of X-rays in a supermassive black hole’s jet, answering a question that has been unresolved since the earliest days of X-ray astronomy. Their findings are described in a paper published in The Astrophysical Journal Letters, […]

NASA’s Webb Observes Exoplanet Whose Composition Defies Explanation

Scientists using NASA’s James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our understanding of how it formed.  Officially named PSR J2322-2650b, this Jupiter-mass object appears to have an exotic helium-and-carbon-dominated atmosphere unlike any ever seen before. Soot clouds likely float through the […]

NASA’s Webb, Curiosity Named in TIME’s Best Inventions Hall of Fame

Two icons of discovery, NASA’s James Webb Space Telescope and NASA’s Curiosity rover, have earned places in TIME’s “Best Inventions Hall of Fame,” which recognizes the 25 groundbreaking inventions of the past quarter century that have had the most global impact, since TIME began its annual Best Inventions list in 2000. The inventions are celebrated […]

Massive Stars Make Their Mark in Hubble Image

This NASA/ESA Hubble Space Telescope image features a glittering blue dwarf galaxy called Markarian 178 (Mrk 178). The galaxy, which is substantially smaller than our own Milky Way, lies 13 million light-years away in the constellation Ursa Major (the Great Bear). Mrk 178 is one of more than 1,500 Markarian galaxies. These galaxies get their […]

NASA’s Chandra Finds Small Galaxies May Buck the Black Hole Trend

Most smaller galaxies may not have supermassive black holes in their centers, according to a recent  study using NASA’s Chandra X-ray Observatory. This contrasts with the common idea that nearly every galaxy has one of these giant black holes within their cores, as NASA leads the world in exploring how our universe works. A team […]

NASA’s Webb Detects Thick Atmosphere Around Broiling Lava World 

Researchers using NASA’s James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky planet outside our solar system, as NASA leads the world in exploring the universe from the Moon to Mars and beyond. Observations of the ultra-hot super-Earth TOI-561 b suggest that the exoplanet is surrounded by a […]

NASA’s TESS Spacecraft Triples Size of Pleiades Star Cluster

Astronomers have revolutionized our understanding of a collection of stars in the northern sky called the Pleiades. They used data from NASA’s TESS (Transiting Exoplanet Survey Satellite) and other observatories as NASA explores the secrets of the universe for the benefit of all, from the Moon to Mars and beyond. By examining the rotation, chemistry, […]

Hubble Studies Star Ages in Colorful Galaxy

Stars of all ages are on display in this NASA/ESA Hubble Space Telescope image of the sparkling spiral galaxy called NGC 6000, located 102 million light-years away in the constellation Scorpius. NGC 6000 has a glowing yellow center and glittering blue outskirts. These colors reflect differences in the average ages, masses, and temperatures of the […]
