NASA Van Allen probes confirm Earth as giant particle accelerator

The NASA Van Allen twin probes launched last year have revealed that the Earth is a giant particle accelerator. Recently it was reported that particles in the magnetosphere sometimes accelerate across distances of a few hundred meters. But the newer discovery shows the acceleration can occur across hundreds of thousands of kilometers. The data will be helpful to to scientists helping satellite operators and the International Space Station to predict and prepare for the destructive tendencies of the seemingly random fluctuations that can occur in the magnetosphere.

NASA shows us what Antarctica would look like without ice

NASA shows us what Antarctica would look like without ice

Due to its location, the frigid continent of Antarctica is covered with nothing but ice, making it seem like the continent is nothing but boring flat land. However, thanks to a computer-generated simulation, we get to see that Antarctica is actually bumpy and pretty unique -- it's just that we don't get to see it with all that ice covering it up.

Chris Hadfield and crew safely return to Earth from International Space Station

Chris Hadfield and crew safely return to Earth from International Space Station

We get all sorts of welcomes in life, but few of them are as grand as the one you'd no doubt receive returning to Earth after having hovered above it for 144 days. Such was the case for Commander Chris Hadfield and the rest of his crew that was aboard the International Space Station, all of whom have just safely landed on our home planet in Dzhezkazgan, Kazakhstan.

Earth’s carbon dioxide levels reach near-record high

Earth’s carbon dioxide levels reach near-record high

According to scientists and researchers at the National Oceanic and Atmospheric Administration, carbon dioxide levels on Earth have reached a level that hasn't been seen in at least three million years. Scientists believe that large changes in the climate and sea levels are to blame for the rising amount of carbon dioxide.

Study suggests water on the Moon came from Earth

Study suggests water on the Moon came from Earth

Scientists and researchers have discovered that droplets of water found in lunar rocks brought back from the Moon are identical on a chemical level from that of samples of ancient Earth. The rocks used in the study came from samples brought back by Apollo 15 in 1971 and Apollo 17 in 1972, the latter being NASA's last mission to the moon.

Rhinos extinct in Mozambique National Park

Rhinos extinct in Mozambique National Park

Rhinoceroses are being added to the ever-growing list of endangered species, and now, the horned animals are said to be extinct in parts of Africa where they used to thrive -- specifically in Mozambique, where officials of Mozambique National Park are reporting that no rhinos had been seen in the park since January.

Earth’s core as hot as the Sun, claim scientists

Earth’s core as hot as the Sun, claim scientists

A recent X-ray analysis of molten iron has uncovered that the Earth’s inner core is actually a lot hotter than we all thought previously. According to a team scientists from French research agency CEA, French National Center for Scientific Research CNRS, and the European Synchrotron Radiation Facility ESRF, the inner core of the Earth is said to be 6,000 degrees Celsius, or 10,800 degrees Fahrenheit.
