Venus is the second planet from the Sun. Credit: NASA ETH researchers used computer simulations to classify the current activity of corona structures on the surface of Venus. To their surprise, they found a previously undiscovered ring of fire on our neighboring planet. Years ago, planetary researchers discovered unusual circular structures […]

Animation New 3D model provides evidence that Venus is churning inside. A new study identified 37 recently active volcanic structures on Venus. The study provides some of the best evidence yet that Venus is still a geologically active planet. A research paper on the work, which was conducted by researchers at the […]

Extensional faults (arrows) on the surface of Pluto indicate expansion of the dwarf planet’s icy crust, attributed to freezing of a subsurface ocean.

Artist’s conception of Kepler telescope observing planets transiting a distant star. Credit: NASA Ames/W Stenzel There may be as many as one Earth-like planet for every five Sun-like stars in the Milky Way Galaxy, according to new estimates by University of British Columbia astronomers using data from NASA’s Kepler mission. To be considered Earth-like, a […]

To the human eye, Mercury may resemble a dull, grey orb but this enhanced-color image from NASA’s Messenger probe, tells a completely different story. Swathes of iridescent blue, sandy-colored plains and delicate strands of greyish white, create an ethereal and colorful view of our Solar System’s innermost planet. Credit: NASA […]

This false-color composite image shows auroras (depicted in green) above the cloud tops of Saturn’s south pole. The 65 observations used here were captured by Cassini’s visual and infrared mapping spectrometer on November 1, 2008.

This updated catalog of trans-Neptunian objects and the methods used to find them could aid in future searches for undiscovered planets in the far reaches of the solar system. Using data from the Dark Energy Survey (DES), researchers have found more than 300 trans-Neptunian objects (TNOs), minor planets located in […]
