Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves. Their discovery opened a new...
Researchers may have answered one of space science's long-running questions -- and it could change our understanding of how life began. Carbon-rich asteroids are abundant in...
Astronomers are investigating the longest and most energetic bursts of X-rays seen from a newly awakened black hole. Watching this strange behavior unfold in real time...
The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the Sun. A Southwest Research Institute-led team of scientists...
Every galaxy is thought to form at the center of a dark matter halo. Stars are formed when gravity within dark matter halos draws in gas,...
Astronomers have discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to...
An international team is currently closely tracking the near-Earth asteroid 2024 YR4. The impact probability estimates for the year 2032 has been reduced from a peak...
For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals...
Astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0. This record-breaking detection is making astronomers rethink how quickly galaxies formed in the early Universe.
The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet...
