New research finds that despite large rivers and seas of liquid methane, Saturn's moon Titan seems mostly devoid of river deltas, raising new questions about the...
Researchers have developed a new coronagraph that could make it possible to see distant exoplanets obscured by light from their parent stars.
An international team has discovered the most distant spiral galaxy candidate known to date. This ultra-massive system existed just one billion years after the Big Bang...
Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.
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...
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...
Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the...
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...
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.
