NASA’s James Webb Space Telescope has revealed a colorful array of massive stars and glowing cosmic dust in the Sagittarius B2 molecular cloud, the most massive and active star-forming region in our Milky Way galaxy. “Webb’s powerful infrared instruments provide detail we’ve never been able to see before, which will help us to understand some … Read more
NASA’s Nancy Grace Roman Space Telescope will help scientists better understand our Milky Way galaxy’s less sparkly components — gas and dust strewn between stars, known as the interstellar medium. One of Roman’s major observing programs, called the Galactic Plane Survey, will peer through our galaxy to its most distant edge, mapping roughly 20 billion … Read more
As far back as 1912, astronomers realized that the Andromeda galaxy — then thought to be only a nebula — was headed our way. A century later, astronomers using NASA’s Hubble Space Telescope were able to measure the sideways motion of Andromeda and found it was so negligible that an eventual head-on collision with the … Read more
NASA’s Nancy Grace Roman Space Telescope team shared Thursday the designs for the three core surveys the mission will conduct after launch. These observation programs are designed to investigate some of the most profound mysteries in astrophysics while enabling expansive cosmic exploration that will revolutionize our understanding of the universe. “Roman’s setting out to do … Read more
Observations from NASA’s James Webb Space Telescope have provided a surprising twist in the narrative surrounding what is believed to be the first star observed in the act of swallowing a planet. The new findings suggest that the star actually did not swell to envelop a planet as previously hypothesized. Instead, Webb’s observations show the … Read more
Follow-up research on a 2023 image of the Sagittarius C stellar nursery in the heart of our Milky Way galaxy, captured by NASA’s James Webb Space Telescope, has revealed ejections from still-forming protostars and insights into the impact of strong magnetic fields on interstellar gas and the life cycle of stars. “A big question … Read more
NASA’s latest space observatory is targeting a March 8 liftoff, and the agency’s PUNCH heliophysics mission is sharing a ride. Here’s what to expect during launch and beyond. In a little over a day, NASA’s SPHEREx space telescope is slated to launch from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket. … Read more
NASA astronaut Don Pettit used a camera with low light and long duration settings to capture this Jan. 29, 2025, image of the Milky Way appearing beyond Earth’s horizon. At the time, the International Space Station was orbiting 265 miles above the Pacific Ocean off the coast of Chile just before sunrise. Pettit is part … Read more
Data from NASA’s retired Spitzer Space Telescope has given scientists new insights into why some supermassive black holes shine differently than others. In images from NASA’s retired Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the heart of the Andromeda galaxy. It turns out these streams … Read more
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
