Astronomers have discovered that super-Earth exoplanets are more common across the universe than previously thought. While it can be relatively easy to locate worlds that orbit...
Geologists weigh in on a long-running debate about Mars: Billions of years ago, was the Red Planet warm and wet or cold and dry?
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 helped overturn the popular theory that water on Earth originated from asteroids bombarding its surface; Scientists have analyzed a meteorite analogous to the early...
A new study analyzing data from NASA's Perseverance rover has uncovered compelling evidence of multiple mineral-forming events just beneath the Martian surface -- findings that bring...
Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not...
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 discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to...
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...
