The debate about the origin of Earth’s water just got deeper. The European Space Agency’s (ESA) comet-chasing spacecraft Rosetta has sent back some interesting information regarding water vapor it detected and analyzed on its target, Comet 67P/Churyumov-Gerasimenko. According to the ESA and an international group of scientists, the analysis shows that the chemical composition of […]

Exploratory missions to Mars, such as NASA’s Curiosity Rover, have provided more and more evidence that Mars at one time was warm enough for water to flow on its surface. Now a new study published in the journal “Nature Geoscience” has found that those ancient, warm periods on the Red Planet probably took place in […]

Scientists Catch Photosynthesis in Action Researchers have snapped the very first images of photosynthesis as it happens. Photosynthesis is the process which plants use to convert light energy into chemical energy, which is then stored as sugar. Using the U.S. Department of Energy’s LCLS x-ray laser, the world’s most powerful, the researchers imaged the part […]

New evidence suggests there  might be oceans of water far beneath Earth’s surface. Northwestern University geophysicist Steve Jacobsen, along with University of New Mexico seismologist Brandon Schmandt, found evidence of water in pockets of hot magma about 645 km beneath North America within the transition zone between Earth’s upper and lower mantle. “It alters our […]

Odd X-ray Signal Might be Sign of Dark Matter Strange X-ray emissions from galaxy clusters– hundreds of galaxies connected to each other by gravity–are providing clues about mysterious dark matter. Dark matter–if it really does exist–is thought to be invisible, doesn’t produce or attract light, and makes up a majority, 84.5 percent, of the matter […]

Study Confirms Earth’s Magnetic Field is Weakening

Earth’s magnetic field is weakening, according to  measurements taken over the past six months by the European Space Agency’s (ESA) Swarm satellite constellation. The measurements–taken between January and June 2014–come from the first high-resolution results made by Swarm, and also indicate that the magnetic field has declined most dramatically in the Western Hemisphere while increasing […]
