University of Cambridge Video of magnetic field lines 'slipping reconnection' bring scientists a step closer to predicting when and where large flares will occur Scientists have for the first time witnessed the mechanism behind explosive energy releases in the Sun's atmosphere, confirming new theories about how solar flares are created. New footage put together by an international team led by University of Cambridge researchers shows how entangled magnetic field lines looping from...

Don’t Forget F-type Stars In The Search For Life
2014-03-27 13:19:34

University of Texas at Arlington Scientists searching for habitable planets beyond Earth shouldn’t overlook F-type stars in favor of their more abundant, smaller and cooler cousins, according to new research from University of Texas at Arlington physicists. Stars fall into seven lettered categories according to their surface temperature, but they also differ in other factors such as mass, luminosity and abundance in the universe. Scientists looking for habitable planets typically...

Hardy Star Survives Supernova Blast
2014-03-21 05:24:03

[ Watch the Video: What Is A Supernova? ] NASA When a massive star runs out of fuel, it collapses and explodes as a supernova. Although these explosions are extremely powerful, it is possible for a companion star to endure the blast. A team of astronomers using NASA’s Chandra X-ray Observatory and other telescopes has found evidence for one of these survivors. This hardy star is in a stellar explosion’s debris field − also called its supernova remnant − located in an HII...

Reconstructing The Death Of Supernovae In 3D Offers New Insights
2014-03-18 13:29:42

Lee Rannals for redOrbit.com - Your Universe Online An astrophysicist has created a new three-dimensional model that provides new insight into the death throes of supernovae. The model, created by W. David Arnett, Regents Professor of Astrophysics at the University of Arizona, is the first to represent the start of a supernova collapse in 3D. It shows how the turbulent mixing of elements inside the dying stars causes them to expand, contract and spit out matter before exploding....

HSINCHU, March 18, 2014 /PRNewswire/ -- Lextar Electronics Corp. ("Lextar" or the "Company) (TAIEX: 3698) will release an ultra slim direct-lit panel light. Only 28mm in thickness, this new product is free from the stereotypically bulky exterior of its comparable products. Besides, it minimized the number of LED thanks to Lextar's state-of-the-art direct-lit backlighting technology. Lextar's new ultra-slim direct-lit panel light features low glare, creating a new alternative for...

Turbulent Mixing Inside Stars Causes them to Expand, Contract, Eject and Explode, According to 3-D Model Described in the Journal "AIP Advances" WASHINGTON, March 18, 2014 /PRNewswire-USNewswire/ -- A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible....

Mid-Level Solar Flare Seen By NASA's Solar Dynamics Observatory
2014-03-13 12:05:22

Karen C. Fox, NASA The sun emitted a mid-level solar flare, peaking at 6:34 p.m. EDT on March 12, 2014, and NASA's Solar Dynamics Observatory, or SDO, captured an image of it. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event may...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

The Sun -- intensely hot, self-luminous body of gases at the center of the solar system. Its gravitational attraction maintains the planets, comets, and other bodies of the solar system in their orbits. The sun is actually a star of about medium size; it appears larger than the other stars because of its relative nearness to the earth. The earth's distance from the sun varies from 91,377,000 mi (147,053,000 km) at perihelion to 94,537,000 mi (152,138,000 km) at aphelion (see apsis). The...

Crab Nebula -- The Crab Nebula (Messier 1, NGC 1952) is the object the which started Charles Messier logging non-cometary objects on his Messier Catalog. It is the expanding cloud of gas thrown off in the explosion that gave rise to the 1054 supernova recorded by Chinese astronomers, now more than 6 light years across (the nebula is currently expanding at 1000 km/sec and the total mass of ejected material is about 0.1 solar masses). The supernova which produced it was bright enough to...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
