A Yale-led team using the new MOTHRA telescope found 22 bow shocks in the Helix Nebula's outer halo, capturing dying-star debris being broken apart in real time.
The James Webb Space Telescope detected dust and water forming around the aging star IRS 3, located just 0.55 light-years from the Milky Way's central black hole.
As a total solar eclipse crossed Greenland, Iceland, and Spain on August 12, 2026, NASA flew a high-altitude jet and dozens of scientific balloons to study the Sun's corona and its effects on Earth's atmosphere.
ALMA observations show a 1-trillion-mile gas streamer feeding GW Orionis is aligned with the tilted outer ring of its planet-forming disk, University of Florida astronomers report.
An independent search of archival JWST imaging uncovered a previously uncatalogued gravitational arc in the massive cluster MACS J0308.9+2645, now under review for publication in a Japanese journal.
A decade of stellar occultation observations, led by the Planetary Science Institute, show Pluto's atmospheric pressure has dropped by up to 16 percent since 2021.
NASA's Lucy spacecraft photographed Trojan asteroids Eurybates, Polymele, Leucus, and Orus from hundreds of millions of miles away, testing cameras ahead of its 2027 flybys.
NASA's IXPE and NICER measured X-ray polarization nearly three times higher than similar magnetars, offering astronomers the most definitive evidence yet for a 90-year-old quantum prediction.
Boston College researchers determined that Martian meteorite Northwest Africa 13441 crystallized 1.273 billion years ago, filling a long-standing gap in the shergottite meteorite age record.
The NSF Daniel K. Inouye Solar Telescope has captured direct observational evidence of Kelvin-Helmholtz instability on the Sun's photosphere, confirming a process theorized since 1870.
