In late February, people in the Northern Hemisphere can look up for a special sight: six planets will all be visible from clear and dark night skies. New sonifications from NASA’s Chandra X-ray Observatory released Feb. 25 will help commemorate this latest “planetary parade.” Because the planets in our solar system travel around the Sun
A full description of the methods is provided in the Supplementary Information. All dilution percentages are v/v unless specified otherwise. No statistical methods were used to predetermine sample size. No blinding and randomization were used.

Researchers uncovered hundreds of previously unknown deep-sea species, giving the scientific community a better idea of what lives on the ocean floor. A recent study published in Nature Ecology and Evolution found 4,350 wildlife specimens on the seabed. Of those, about 3,826 could be identified from 788 known species, meaning over 500 specimens of potential

Solar power offers a cleaner path. We install panels and convert sunlight into electricity, which can power radiators. But the sun always sets. When night falls or winter
Pushing the body towards ultra-marathon distances can cause red blood cells to be less flexible, potentially impacting their ability to deliver oxygen and remove waste throughout the body, a new study shows. Although the study didn’t look at long-term health implications, there are reasons to believe that hitting our biological limits in this way may
Astronomers have used the world’s largest and most sensitive low-frequency radio telescope array LOFAR (or Low-Frequency Array), to create the largest radio survey of the cosmos, revealing 13.7 million cosmic objects and events. These include jets erupting from feeding supermassive black holes, colliding galaxies, and supernova explosions that mark the deaths of massive stars and
HOUSTON — NASA’s Mike Fincke identified himself Wednesday as the astronaut whose medical condition prompted the space agency’s first medical evacuation. In a written statement, the 58-year-old spaceflight veteran revealed he was the ailing crew member last month aboard the International Space Station. He did not say what was wrong with him but explained that

Some of the universe’s most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front ploughs into its surrounding environment. In new research accepted for publication in The Astrophysical Journal, we have discovered what may be the clearest
Way, way back in the days when men wore beards and wide-lapelled suits in exotic colors, only NASA had access to photovoltaics and ‘solar’ meant solar thermal. In those days of appropriate technology, it was thought that the ultimate in thermal mass was a phase-change material– a salt or wax that in melting and re-freezing
