NASA’s Roman Team Selects Survey to Map Our Galaxy’s Far Side – NASA

NASA’s Nancy Grace Roman Space Telescope team has announced plans for an unprecedented survey of the plane of our Milky Way galaxy. It will peer deeper into this region than any other survey, mapping more of our galaxy’s stars than all previous observations combined. “There’s a really broad range of science we can explore with … Read more

NASA Astronomer Sees Power in Community, Works to Build More – NASA

Science is often portrayed as a solitary affair, where discoveries are made by lone geniuses toiling in isolation. But Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center in California’s Silicon Valley, says solving problems with the people around her is one of the best parts of her job.  “Oh, man, working with people … Read more

Webb Shows Many Early Galaxies Looked Like Pool Noodles, Surfboards – NASA

Researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like surfboards and pool noodles – and are rarely round, like volleyballs or frisbees. “Roughly 50 to 80% of the galaxies we studied appear to be flattened in two dimensions,” explained lead author … Read more

NASA’s Webb Discovers Dusty ‘Cat’s Tail’ in Beta Pictoris System – NASA

NASA’s Webb Discovers Dusty ‘Cat’s Tail’ in Beta Pictoris System – NASA

Beta Pictoris, a young planetary system located just 63 light-years away, continues to intrigue scientists even after decades of in-depth study. It possesses the first dust disk imaged around another star — a disk of debris produced by collisions between asteroids, comets, and planetesimals. Observations from NASA’s Hubble Space Telescope revealed a second debris disk … Read more

NASA’s Webb Finds Signs of Possible Aurorae on Isolated Brown Dwarf – NASA

NASA’s Webb Finds Signs of Possible Aurorae on Isolated Brown Dwarf – NASA

Infrared emission from methane suggests atmospheric heating by auroral processes. Astronomers using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discovery because the brown dwarf, … Read more

Meet the Infrared Telescopes That Paved the Way for NASA’s Webb – NASA

The Webb telescope has opened a new window onto the universe, but it builds on missions going back 40 years, including Spitzer and the Infrared Astronomical Satellite. On Dec. 25, NASA will celebrate the two-year launch anniversary of the James Webb Space Telescope – the largest and most powerful space observatory in history. The clarity … Read more

NASA’s Webb Rings in Holidays With Ringed Planet Uranus – NASA

NASA’s Webb Rings in Holidays With Ringed Planet Uranus – NASA

NASA’s James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic world with rings, moons, storms, and other atmospheric features – including a seasonal polar cap. The image expands upon a two-color version released earlier this year, adding additional wavelength … Read more
