Observations suggest frequent massive eruptions on Jupiter’s moon Io

Observations made using Keck and Gemini observatories, Hawaii, revealed three massive volcanic eruptions on Jupiter's moon Io within a two-week period in August 2013, leading astronomers to speculate that these presumed rare "outbursts" migh

Massive storm systems formed on planet Uranus

As hurricanes threaten the Aloha State, astronomers working at W. M. Keck Observatory on the island of Hawaii were surprised by the appearance of gigantic swirling storm systems on the distant planet Uranus.During the Voyager encounter with Uranus in 1986, only a scant

Asteroid vesta shatters planet formation theory

In the previous Space News, we discussed astronomer's recent admission that they now need a whole new theory to explain about how planets form. Today yet another discovery has shattered conventional ideas about planet formation and the so-called early solar system.

The most thorough map of the Martian surface to date

The United States Geological Survey (USGS) has released the most thorough map of the Martian surface to date. The data for the new map was collected by NASA's Mars Global Surveyor, Mars Odyssey and Mars Reconnaissance Orbiter, and

The atmospheric waves of Venus, key to understanding the superrotation of its atmosphere, deciphered

Venus’ atmosphere rotates up to sixty times faster than its surface, a phenomenon known as superrotation whose origin hast yet to be satisfactorily explained...Venus is a slowly rotating planet since it takes about two hundred and forty three terrestrial days to c

Steve Smith: Mars - The Great Desert in 3D - EU2014

Martian areography tells a story of incredibly violent events. It appears from the many images sent to Earth that it once experienced powerful plasma discharges on a massive scale. Burned and blasted craters, piles of scorched dust covering almost an entire hemisphere,

Mysterious 'Magic Island' appears on Saturn moon

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

Cracks in Pluto's moon could indicate it once had an underground ocean

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

Venus now the first planet after Earth to get daily space weather reports

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

Jupiter’s Great Red Spot shrinking at increasing rate

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

Ganymede may harbor ice and oceans stacked up in several layers

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

Gullies and debris flow deposits - traces of recent water on Mars

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

First Earth-size planet found In the 'habitable zone' of another star

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
