NASA's MAVEN mission finds Mars has a twisted...
on Oct 19, 2017 at 10:18 pm
Mars has an invisible magnetic 'tail' that is twisted by interaction with the solar wind, according to new research using data from NASA's MAVEN spacecraft. […]
New NASA study improves search for habitable...

New NASA research is helping to refine our understanding of candidate planets beyond our solar system that might support life. […]
Noxious ice cloud on Saturn's moon Titan
on Oct 19, 2017 at 2:10 pm
Researchers with NASA's Cassini mission found evidence of a toxic hybrid ice in a wispy cloud high above the south pole of Saturn's largest moon, Titan. […]
A solar flare recorded from Spain in 1886
on Oct 19, 2017 at 2:07 pm
Satellites have detected powerful solar flares in the last two months, but this phenomenon has been recorded for over a century. On Sept. 10, 1886, at the age of just 17, a young amateur astronomer using a modest telescope observed from Madrid one of these sudden flashes in a sunspot. […]
Scientists dig into the origin of organics on...
on Oct 18, 2017 at 7:18 pm
Since NASA's Dawn spacecraft detected localized organic-rich material on Ceres, scientists have been digging into the data to explore different scenarios for its origin. After considering the viability of comet or asteroid delivery, the preponderance of evidence suggests the organics are most […]
Solar eruptions could electrify Martian moons
on Oct 18, 2017 at 4:41 pm
Powerful solar eruptions could electrically charge areas of the Martian moon Phobos to hundreds of volts, presenting a complex electrical environment that could possibly affect sensitive electronics carried by future robotic explorers, according to a new NASA study. The study also considered […]
A mission to Mars could make its own oxygen...
on Oct 18, 2017 at 3:33 pm
Plasma technology could hold the key to creating a sustainable oxygen supply on Mars, a new study has found. It suggests that Mars, with its 96 per cent carbon dioxide atmosphere, has nearly ideal conditions for creating oxygen from CO2 through a process known as decomposition. […]
Potential human habitat located on the moon
on Oct 18, 2017 at 2:43 pm
A new study confirms the existence of a large open lava tube in the Marius Hills region of the moon, which could be used to protect astronauts from hazardous conditions on the surface. […]
Space greens beat the blues
on Oct 18, 2017 at 1:11 pm
Where people will go in the cosmos, plants will go, say researchers. Plants may also play a key role in maintaining the psychological well-being of space crews. The next frontier of space plant experimentation is to examine the psychological impact of plant life on astronauts. […]
How bright is the moon, really?
on Oct 17, 2017 at 8:37 pm
The National Institute of Standards and Technology (NIST) is planning to take new measurements of the Moon's brightness, a highly useful property that satellites rely upon every day. […]
To keep Saturn's A ring contained, its moons...
on Oct 17, 2017 at 4:43 pm
For three decades, astronomers thought that only Saturn's moon Janus confined the planet's A ring -- the largest and farthest of the visible rings. But after poring over NASA's Cassini mission data, astronomers now conclude that the teamwork of seven moons keeps this ring corralled. […]
Study shows how water could have flowed on 'cold...
on Oct 17, 2017 at 3:43 pm
Research by planetary scientists finds that periodic melting of ice sheets on a cold early Mars would have created enough water to carve the ancient valleys and lakebeds seen on the planet today. […]
Looking for microbe 'fingerprints' on simulated...
on Oct 17, 2017 at 3:01 pm
Scientists are searching for unique bio-signatures left on synthetic extraterrestrial minerals by microbial activity. A new paper describes investigations into these signatures at a miniaturized 'Mars farm' where researchers can observe interactions between the archaeon Metallosphaera sedula and […]
Filling the early universe with knots can explain...
on Oct 16, 2017 at 11:03 pm
Filling the universe with knots shortly after it popped into existence 13.8 billion years ago provides a neat explanation for why we inhabit a three-dimensional world. That is the basic idea advanced by an out-of-the-box theory developed by an international team of physicists. […]
Catch a fleeting kilonova
on Oct 16, 2017 at 5:26 pm
Alerted by the first-ever gravitational waves caused by two neutron stars merging, astronomers detect the resulting optical flash. […]
