Scientists may have discovered a minor planet with a ring system like Saturn's. Called Chiron, the minor planet may reveal new insights into centaurs, which are a class of minor planets that possess qualities of both asteroids and comets.
Scientists have found evidence in meteorites that may hint at the discovery of a previously unknown region within the protoplanetary disk, a swirling disk of dust and gas that gave rise to the planets in our solar system.
Scientists have described possible planetary systems where a gravitational nudge from one planet with just the right orbital configuration could have a devastating impact on the orbit and climate of another, possibly habitable world.
On March 11, the sun unleashed a solar flare that peaked at 12:22 p.m.
After watching aurorae glowing above Jupiter's moon, Ganymede, scientists believe that the world may possess an underground ocean.
NASA's Cassini spacecraft has revealed some startling new findings about Saturn's moon, Enceladus. It's shown that the moon exhibits signs of hydrothermal activity, which may be similar to what is seen in the deep oceans on Earth.
It turns out that the Milky Way galaxy is a bit larger than expected. After re-examining the data from the Sloan Digital Sky Survey, scientists have found that our galaxy is at least 50 percent larger than commonly estimated.
Scientists have captured a spectacular new image of the southern constellation of Ara with the help of the VLT Survey Telescope in Chile.
The Karl G. Jansky Very Large Array (VLA) has captured a spectacular, detailed image of one of the most fascinating regions of the universe. It's taken a picture of an area where clusters of hundreds of galaxies are colliding with one another.
