Scientists Explain the Formation of the Unusual Third Van Allen Radiation Ring

Scientists Explain the Formation of Third Radiation Ring

UCLA scientists explain the formation of an unusual third radiation ring that briefly appeared between the inner and outer Van Allen radiation belts in September 2012 and persisted for a month. Since the discovery of the Van Allen radiation belts in 1958, space scientists have believed these belts encircling the Earth consist of two doughnut-shaped […]

Researchers Identify Molecular Factors that Push the Domino of Life into Motion

Researchers Identify Molecular Finger that Starts the Domino of Life

In a newly published study, Yale University geneticists report that three factors — Nanog, Pou5f1 (or Oct4) and SoxB1 — are indeed needed to push the domino of life into motion in zebrafish. These are the same factors that reprogram adult human cells into an embryonic-like state. The basics of conception are familiar to any […]

Astronomers Probe the Nature of Strong Galactic Nuclear Winds

Astronomers Use Herschel to Study Twenty Four Infrared Luminous Galaxies

Astronomers used the Herschel Space Telescope to study twenty-four infrared luminous galaxies, revealing the presence of very fast motions in galactic nuclear winds, up to 2000 kilometers per second. The most luminous galaxies in our universe are not particularly bright in the visible. Most of their energy output (which can be hundreds or even thousands […]

Curiosity Fails to Detect Methane on Mars

Curiosity Detects No Methane on Mars

To the surprise of many researchers, NASA’s Curiosity rover has failed to detect methane on Mars. Pasadena, California — Data from NASA’s Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data reported by U.S. and international scientists indicated positive detections. The roving laboratory performed extensive tests […]

Astronomers Discover Enormous Arms of Hot Gas in the Coma Cluster of Galaxies

Hot Gas Discovered in the Coma Cluster of Galaxies

Using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton, researchers have discovered long arms of hot gas in the Coma cluster of galaxies. These arms span at least a half a million light years and were likely formed by hot gas being stripped and left behind by smaller clusters of galaxies as they merged with Coma. […]

NASA Scientists Determine Europa Likely Spun on a Tilted Axis

NASA Scientists Find Evidence that Europa Likely Spun on a Tilted Axis at Some Point

By using data from NASA’s Galileo spacecraft to analyze the distinctive cracks lining the surface of Europa, NASA scientists determined that Europa likely rotated around a tilted axis at some point. This tilt could influence calculations of how much of Europa’s history is recorded in its frozen shell, how much heat is generated by tides […]
