NASA says a precise SpaceX Falcon Heavy launch and flawless early course correction have left the Nancy Grace Roman Space Telescope with enough propellant for at least 22 years of operations, more than double the mission's original five-year baseline plan. The $4.3 billion observatory launched August 30 from Kennedy Space Center and is now heading to its observation post to survey wide swaths of the sky with Hubble-level resolution.

A team led by Xin Li at Westlake University identified an intermediate-mass black hole, roughly 35,000 times the sun's mass, sitting outside the star-forming disk of the dwarf galaxy UGCA 320, about 20 million light-years away. Hubble imaging and MUSE spectroscopy showing broad Balmer emission confirmed the object is actively accreting material as it drifts through the galaxy, dragging surrounding gas behind it.

NASA launched the Nancy Grace Roman Space Telescope on August 30, marking the first space telescope named after a woman. The mission, previously known as WFIRST, will study dark matter, dark energy, and exoplanets, continuing work in the field Roman helped establish as NASA's first chief of astronomy in 1959.

Astronomers using the Hubble Space Telescope have identified a ten-sided cloud formation encircling Saturn's south pole, a counterpart to the long-known hexagon at the planet's north pole. The decagon, detailed in a new Science Advances study, has sides roughly 16,800 kilometers long and sits near a jet stream blowing close to 260 miles per hour, even though the shape itself drifts at less than 6 mph.

Scientists at the LUX-ZEPLIN experiment, which uses 10 tonnes of liquid xenon buried in South Dakota's Sanford Underground Research Facility, recorded one unusual flash consistent with a WIMP particle striking a xenon nucleus. The result, described in a preprint that has not yet been peer-reviewed, is far from confirmed but has generated excitement because it could represent the long-sought direct detection of dark matter.

Researchers on the LUX-ZEPLIN experiment at South Dakota's Sanford Underground Research Facility reported a lone high-energy event in their 10-tonne liquid xenon detector, recorded sometime in 2023 or 2024, that matches the expected signature of a dark matter particle striking an atomic nucleus. The team announced the finding at a physics conference in Japan and posted details in a preprint, while cautioning that a single event is not proof.

NASA's $4.3-billion Nancy Grace Roman Space Telescope launched successfully atop a SpaceX rocket from Kennedy Space Center, carrying the largest infrared digital camera ever built along with a large mirror originally built for a spy satellite. The observatory, named after NASA's first chief astronomer, is now headed to its operational orbit to study dark energy, map millions of Milky Way stars, and search for exoplanets.

NASA has named its next major space observatory after Nancy Grace Roman, the agency's first chief astronomer and a key figure behind Hubble. The telescope will offer a field of view at least 100 times wider than Hubble's, allowing it to capture light from potentially a billion galaxies over its operational life.
