[ Watch the Video: Fermi Data Hints At New Dark Matter Clues ] Francis Reddym, NASA Goddard Space Flight Center A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the...

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...

redOrbit Staff & Wire Reports - Your Universe Online While experts might not know exactly how supermassive black holes grow to sizes up to a billion times that of our sun, astronomers using NASA’s Wide-field Infrared Survey Explorer (WISE) believe they have discovered the so-called cosmic seeds that will ultimately become gravity-rich regions from which light cannot escape. Black holes come in various sizes, with the smallest ones only a few times greater in mass than our sun and...

ENERTIA® CEO Michael Sykes announces three new Extreme EX models of the Award-Winning Green kit-home series, with beefed up thermal mass for more inertia, and reflective hidden internal surfaces like a thermos bottle. Because they are connected to the earth, and face the sun, Enertia homes can maintain livable conditions when there is no electricity, or fuel supply. Youngsville, NC (PRWEB) March 25, 2014 Few homes are ready for the next Polar Vortex, with power outages and shortages...

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...

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....

NASA's WISE Spacecraft Has Yet To Uncover Planet 'X' Beyond Pluto
2014-03-10 08:36:02

redOrbit Staff & Wire Reports - Your Universe Online While NASA’s Wide-Field Infrared Survey Explorer (WISE) has uncovered thousands of new stars during its multi-year mission, it has been unable to collect any evidence supporting the supposed existence of a large but unseen celestial body believed to be located somewhere beyond Pluto’s orbit. This supposed celestial body is commonly referred to as “Planet X” -- alternatively “Nemesis” or “Tyche." However, despite the...

Astronomers Use Cluster Of Galaxies As A Giant Telescope

[ Watch the Video: A Telescope Bigger Than A Galaxy ] April Flowers for redOrbit.com - Your Universe Online On a starry night, around 400 years ago, Galileo turned his primitive spyglass toward the sky. In just a few nights, he learned more about the stars than all of the scientists and philosophers before him, combined. Since those historic nights, astronomers have operated under a single imperative: make bigger telescopes. The power of optics has grown a million-fold as the 21st...

A Wide Range Of Masses Observed In Type Ia Supernovae
2014-03-04 13:06:14

Lee Rannals for redOrbit.com - Your Universe Online Astronomers, publishing a paper in the Monthly Notices of the Royal Astronomical Society, show how Type Ia supernovae have a range of masses. Scientists have been confident in knowing why Type Ia supernovae are all so much alike. Most of them assumed that carbon-oxygen white dwarf stars capture additional mass by stripping it from a companion star or by merging with another white dwarf. Scientists assumed this class of supernova were...

sunspot
2014-03-01 05:57:56

Karen C. Fox, NASA's Goddard Space Flight Center A giant sunspot – a magnetically strong and complex region on the sun's surface – has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation. Scientists track sunspots that are part of active regions, which often produce large explosions on the sun such as solar flares and coronal mass ejections, or CMEs. Each time an active...

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...

This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Physics
2014-01-12 00:00:00

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Astronomy and Astrophysics Review
