New research reveals that as much as one half of all of Earth’s current water supply is older than the Sun. An international team of scientists led by Ilse Cleeves at the University of Michigan looked back into creation of Earth and our solar system to find out where all of the water came from. […]

Two Martian Probes Set to Orbit Red Planet
Posted September 19th, 2014 at 8:22 pm (UTC+0)
Two unmanned spacecraft headed to Mars, one launched by the United States and the other by India, will soon reach the Red Planet within days of each other. NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) probe, launched November 18 is set for insertion into Mars orbit (MOI) on Sunday, September 21. India’s first interplanetary spacecraft, […]
Vast Oceans Detected Deep Beneath Earth’s Surface
Posted June 30th, 2014 at 6:58 pm (UTC+0)
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 […]
Study Confirms Earth’s Magnetic Field is Weakening
Posted June 23rd, 2014 at 8:01 pm (UTC+0)
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 […]
Study: Sun Plays Role in Lightning Strikes
Posted June 2nd, 2014 at 7:31 pm (UTC+0)
Lightning is one of nature’s most spectacular and mysterious phenomena, yet there is much scientists still don’t know about it. British researchers have found evidence that high-energy particles, which are blown toward Earth on the solar wind, play a role in triggering lightning on Earth. These energized solar particles can travel from the sun at […]
Scientists Explore Mystery of Antarctica’s Rising
Posted May 28th, 2014 at 7:05 pm (UTC+0)
An altered Antarctic landscape is one of the rarely discussed side effects of accelerated ice melting. For years as the ice grew in Antarctica, its weight compressed the ground beneath it. But when the ice melted and this weight was reduced, the ground sprang back, rebounding over time. However, the ground in the Northern Antarctic […]
New Dating System Could Reveal Secrets of Earth’s Ancient Climate
Posted April 21st, 2014 at 7:51 pm (UTC+0)
Scientists have a new tool in the quest to learn more about Earth’s ancient climate, including the mechanisms that plunged our planet into and out of ice ages. The new tool is a scientific technique called radiometric krypton dating, which recently allowed researchers to accurately determine the age of a 120,000-year-old Antarctic ice core sample. […]
Study: Air Pollution Over Asia Found to Impact Global Weather
Posted April 16th, 2014 at 8:01 pm (UTC+0)
Researchers from Texas, California and Washington recently compared air pollution data provided by the Intergovernmental Panel on Climate Change for the years 1850 through 2000 and found that human-made atmospheric particulates (aerosols) from Asia are having an impact on the Pacific storm track, which is a critical driver of global atmospheric circulation that influences weather […]
