NASA’s Nancy Grace Roman Space Telescope team now is targeting as soon as early September 2026 for launch, ahead of the agency’s commitment to flight no later than May 2027. “Roman’s accelerated development is a true success story of what we can achieve when public investment, institutional expertise, and private enterprise come together to take […]
This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA’s Hubble Space Telescope. The colors in Hubble’s visible light image, which marks the 36th anniversary of the mission’s launch on April 24, are reminiscent of an underwater scene filled with fine-grained sediments […]
The star is escaping the Large Magellanic Cloud for the Milky Way.
NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission has mapped interstellar ice at an unprecedented scale. Covering regions in our Milky Way galaxy more than 600 light-years across, the ice was found inside giant molecular clouds — vast regions of gas and dust where dense clumps of […]
Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal. Unlike in the new movie “Project Hail Mary,” this quieting […]
Astronomers discovered dozens of stellar streams in the Milky Way using Gaia data, offering new clues about galaxy formation and dark matter.
