Astronomers have discovered a bright, mysterious geologic object – where one never existed – on Cassini mission radar images of Ligeia Mare, the second-largest sea on Saturn's moon Titan. Scientifically speaking, this spot is considered a "transient
If the icy surface of Pluto's giant moon Charon is cracked, analysis of the fractures could reveal if its interior was warm, perhaps warm enough to have maintained a subterranean ocean of liquid water, according to a new NASA-funded study.Pluto is an extremely dista
European Space Agency (ESA) announced today they have started issuing regular space weather reports for a spacecraft orbiting planet Venus. This is the first time since the exploration of Solar System has begun that a planet, other than Earth, gets a dedi
The shrinkage of Jupiter's Great Red Spot has been known about since the 1930s but latest images by Hubble Space Telescope confirm the increasing shrinkage rate observed by amateur astronomers since 2012. Science has no answer as to why this is happening.H
The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new study led by JPL's Steve Vance that models the moon's makeup.Previously, the moon
The southern hemisphere of Mars is home to a crater that contains very well-preserved gullies and debris flow deposits. The geomorphological attributes of these landforms provide evidence that they were formed by the action of liquid water in geologically recent time.Wh
Astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" – the range of distance from a star where liquid water might pool on the surface of an orbiting planet and could possibly sustain life. The planet, called
NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet's known moons.Images taken with Cassini's narrow angle camera on Apr
A group of scientists led by Geoffrey Collins of Wheaton College has produced the first global geologic map of Ganymede, Jupiter's seventh moon. The map combines the best images obtained during flybys conducted by NASA's Voyager 1 and 2 spacecraft (1979) and
While Hubble Space Telescope, orbiting around Earth, was able to observe the Saturn's northern auroras in ultraviolet wavelengths, Cassini spacecraft, orbiting around Saturn, got complementary close-up views in infrared, visible-light and ultraviolet
