Earth’s Largest Organism is Deteriorating

October 19, 2018

Researchers in Utah say what many consider to be the world’s largest living organism is dying but could be saved with what they call a ‘mega-conservation’ effort. The Pando aspen clone looks like a forest of trees, but since each of the trees is linked by common genetic markers and possibly one giant root system, […]

Lots of Water Detected in Exoplanet WASP 39b Atmosphere

March 5, 2018

Scientists, who studied a “hot Jupiter-like” exoplanet with NASA’s Hubble and Spitzer space telescopes, were able to detect signs of water in its atmosphere. And, they didn’t just find signs of a little water – but a lot of water, three times the amount of water on our solar system’s largest planet, Jupiter. The exoplanet they […]

Junk Food Puts Immune System Into Overdrive

February 28, 2018

An international group of scientists has found that eating junk food could impact our immune system’s ability to fight disease. Detailing their findings in a new study published by the journal Cell, the researchers, led by the University of Bonn, found evidence that our body’s defense system, reacts the same way to high-calorie foods packed […]

Where are Ceres Large Craters?

July 27, 2016

After NASA’s Dawn spacecraft had passed by the asteroid Vesta, on its way to rendezvous with Ceres, mission scientists noticed that its surface was banged up with a lot of very large craters.  Its biggest impact crater is Rheasilvia, which measures 505 km in diameter. They expected that Ceres would also be seriously pitted with giant impact basins too. […]

Antarctic Glacier Melt Could Raise Global Sea Level by Nearly 3 Meters

May 20, 2016

An international group of scientists say if climate change continues at its current rate, Antarctica’s Totten Glacier might become so unstable that it could eventually release enough water to produce an almost 3 meter rise in the global sea-level sometime in the next several hundred years. A year ago, this same group of scientists from […]

Nearby Supernovae Showered Earth and Moon With Radioactive Iron

April 15, 2016

Artist Animation of Star Explosion (NASA/JPL/Australian National University) Two new studies suggest radioactive bits of a nearby star or stars that exploded into a supernova or supernovae showered the Earth and Moon with radioactive iron a couple of million years ago. Both studies found the stellar evidence in concentrations of an isotope of iron called […]

Moon Born from a Violent Head-On Collision

February 1, 2016

It’s been theorized by a number of scientists that the moon was formed as the result of a collision between an early Earth and a protoplanet known as Theia, named after the mother of the goddess of the moon in Greek mythology, some 4.5 billion years ago (around 100 million years after Earth formed). But scientists seem […]

Curiosity Hits Silica Jackpot; Sleep Aid & Strokes; Freshwater Supply Threatened

December 18, 2015

NASA’s Curiosity Mars Rover Finds Plenty of Silica As they reviewed data gathered by the Mars Rover, scientists found that some rocks in Gale Crater contained the chemical compound silica.  In fact they say it’s a very high amount of the compound. According to the researchers, silica is actually a combination of silicon and oxygen. […]

New Report Predicts Possible Dip in Global CO2 Emissions

December 7, 2015

An international collaboration of scientists, in a new report, predicts the percentage of global carbon dioxide emissions from fossil fuels may actually dip slightly in 2015 compared to 2014 levels. “In 2014, global CO2 emissions from burning fossil fuels grew by just 0.6 percent,” said the report’s lead author Rob Jackson, a professor of Earth […]
