Cosmic Rays Found to Impact Cloud Formation

February 13, 2018

A recent study from scientists at the Technical University of Denmark provides new evidence that cosmic rays play a role in cloud formation, thus affecting our climate. Cosmic rays are a form of fast-moving, high-energy radiation that emanates from the sun or from sources light years away from our solar system. According to the study, […]

Exoplanet Bonanza; Good Sleep = Less Stress; Help Find Planet 9

February 23, 2017

7 Earth-Like Planets Found Orbiting Single Star Scientists using NASA’s Spitzer Space Telescope have found the largest group of earth-like planets circling a single star. A total of seven planets were observed orbiting TRAPPIST-1, a star located only about 40 light years from Earth. The discovery also set a record for the number of planets that were […]

Odd Feature from Galactic Collision; Crack in the Magnetosphere; Smartphones Make Us Trust Less?

November 5, 2016

Galactic Fender-Bender Produces Eye-Lid Shaped Feature A team of astronomers say what started as a fender-bender between two galaxies has sent a torrent of stars and gas crashing through the center of one, which then produced a rare eyelid shaped star formation. Working with the Atacama Large Millimeter/submillimeter Array (ALMA), in Chile, the astronomers identified […]

Study: Sun Plays Role in Lightning Strikes

June 2, 2014

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 […]

New Dating System Could Reveal Secrets of Earth’s Ancient Climate

April 21, 2014

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. […]

Mars Mission Could Accelerate Alzheimer’s in Astronauts

January 2, 2013

Traveling into deep space could accelerate the onset of Alzheimer’s disease, an incurable form of dementia, according to a new report. The NASA-funded study assessed how cosmic radiation would impact the astronauts throughout their trip in deep space. The effect of cosmic radiation on the human body has been a  concern for the US space agency as […]
