A mid-level solar flare, peaking on 3 May, was seen by NASA's Solar Dynamics Observatory. This flare was classified as an M5.7-class flare. M-class flares are the weakest ones. They…
Maybe because it appears as a speck of blood in the sky, the planet Mars was named after the Roman god of war. From the point of view of life as we know it, that's appropriate. The…
Using minute graphite particles 1000 times smaller than the width of a human hair, mechanical engineers at Arizona State University hope to boost the efficiency - and profitability…
Formaldehyde, a poison and a common molecule throughout the universe, is likely the source of the solar system's organic carbon solids - abundant in both comets and asteroids. Scientists…
For the first time, scientists have found convincing evidence for the presence of liquid water in a comet, shattering the current paradigm that comets never get warm enough to melt…
A new polymer-based solar-thermal device is the first to generate power from both heat and visible sunlight - an advance that could shave the cost of heating a home by as much as 40…
Structural studies of some of nature's most efficient light-harvesting systems are lighting the way for new generations of biologically inspired solar cell devices…
At 8:45 p.m. EDT on March 17, the MESSENGER spacecraft will execute a 15-minute manoeuvre that will place it into orbit around Mercury, making it the first craft ever to do so, and…
Scientists have found that calcium, aluminium-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the…
Scientists have performed a micro-probe analysis of the core and outer layers of a pea-sized piece of a meteorite some 4.57 billion years old to reconstruct the history of its formation,…
