Mars Express has captured images of one of the largest outflow channel networks on the Red Planet, providing evidence of ancient mega-flood on Mars, ESA announced today. The Kasei Valles channel system extends around 3 000 km (1 864 miles) from its source region in…
NASA's Curiosity Mars rover has begun a second campaign of investigating active sand dunes on the northwestern flank of Mount Sharp, inside the 160 km (100 miles) wide Gale Crater. The rover also has been observing whirlwinds carrying dust and checking how far…
The Cassini spacecraft has sent the first images of Saturn's atmosphere since the start of its new mission phase. The images reveal the planet's northern hemisphere as well as its unique hexagon jet stream. The newest phase of the NASA's Cassini…
New research suggests the Sputnik Planitia basin on Pluto may have assumed its current location because of the change in the spin of the dwarf planet. The Sputnik Planitia is a 1 000 km (621.4 miles) wide basin situated in the heart-shaped region of the Pluto's…
Saturn's famous hexagon, a structure on the planet's north pole has changed its color from blue to gold over the last four years. The cause is still unknown, and researchers are working to figure it out. The hexagon, a six-sided jet stream, is about 32 000…
Astronomers have again imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa, bolstering other observations suggesting the icy moon erupts with high altitude water plumes. The observation increases the possibility that missions…
Chandra X-ray Observatory was aimed several times at Pluto from February 2014 through August 2015 and made a surprising detection of X-rays being emitted from this largest and best-known object in the Solar System's outermost regions. The observations offer new…
NASA's Juno spacecraft has executed the first of 36 orbital flybys on August 27, 2016, when it came about 4 200 km (2 500 miles) above Jupiter's swirling clouds. It was Juno's first flyby with instruments switch on and it sent back first-ever images of…
New research, led by scientists from the NASA Goddard Institute for Space Studies, suggests Venus and Earth closely resembled each other during the early days of the Solar System, between one and two billion years ago. Venus, now the hottest planet in our Solar…
New research, based on data from ESA's Venus Express satellite, for the first time reveals how the weather patterns on Venus are directly connected to the surface topography of the planet. Results suggest the Venus' thick cloud cover could offer further…
