More Than Half A Million Galaxies Identified And Classified By The ALHAMBRA Project
2013-12-02 12:15:47

RUVID The ALHAMBRA project, led by researchers from the Instituto de Astrofísica de Andalucía and in which the University of Valencia has participated, has identified and classified more than half a million galaxies, after seven years of close observation of the universe from the Observatory of Calar Alto (CAHA, Almería) and thanks to a technique that breaks the stars energy in their colors through astronomical filters. In addition, this research has also allowed calculating the...

ESA Missions Will Seek To Understand The Evolution Of The Universe
2013-11-29 07:25:17

April Flowers for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced today that the hot and energetic Universe and the search for elusive gravitational waves will be the focus of their next two large science missions. Bridging fundamental astrophysics and cosmology themes, both topics will closely study the processes that are crucial to the large-scale evolution of the Universe and its underlying physics. L2, the second large-class mission in ESA's Cosmic...

Milky Way Seen More Clearly Than Ever Thanks To New 3D Map Of The Stars
2013-11-29 04:10:22

Alan McStravick for redOrbit.com - Your Universe Online The Milky Way galaxy recently got a little easier to understand. A group of astronomers created a new 3D map of the stars that reside in the center of the Milky Way which shows, more clearly than ever, the bulge located at the core of our galaxy. Prior to this new representation it was widely believed the stars in the core orbited in a sort of banana shape. However, scientists, publishing this week in the journal Monthly Notices of...

Non-Astronomy Scientists May Help Answer Cosmology Conundrum
2013-11-28 06:41:07

April Flowers for redOrbit.com - Your Universe Online Measuring the invisible and intangible is a challenge for sure, but scientists have made inroads on one front: the study of dark matter and dark energy, two of the most mysterious substances in the cosmos. Although dark matter is intermixed with normal matter, it gives off no light, making it impossible to see. Dark energy presents even more challenges, yet researchers believe it works against gravity to pull our universe apart at...

Plasma-assisted combustion could help make jets fly higher, faster and longer, according to work presented at APS Division of Fluid Dynamics Meeting Mix together air, fuel, and heat and you get combustion, the chemical reaction that powers most engines in planes, trains and automobiles. And if you throw in some ionized gas (plasma), it turns out, you can sustain combustion even in conditions that would otherwise snuff out the reaction: at low air pressure, in high winds or when there's low...

Tycho Supernova Mach 1000 Shock Wave
2013-11-26 15:49:52

John P. Millis, PhD for redOrbit.com - Your Universe Online Somewhere in the Universe a star or stellar remnant is preparing to explode. Binary white dwarf systems can build up in mass as the compact object accretes mass from its companion. Eventually, the tiny ball of matter will explode in a brilliant event known as a supernova. The blast can glow for weeks or even months before eventually fading. However, the shock wave from the event will travel through the surrounding medium,...

LED grow box systems manufacturer, SuperCloset, has released the LED SuperNova, the largest LED grow box on the market today. The increase in grow space and electricity cost savings provided by the LED lighting system enables the SuperNova to be one of the most sought after hydroponic grow boxes. San Francisco, CA (PRWEB) November 20, 2013 The SuperNova stands at 78” tall is 46” wide and 24” deep. It is a behemoth of a hydroponic grow cabinet. It possesses an oversized grow area...

Sunspots Moving Across The Sun
2013-11-14 14:28:37

[ Watch The Video: Sputtering Spot – The Last Days of AR11890 ] NASA Two large, complex sunspots are moving across the face of the sun. One, which produced considerable solar activity in the past weeks, has almost rotated off completely. A new sunspot rounded into view on Nov. 11, 2013 and is now making its way across the Earth-side of the sun. An active region can contain one or more sunspots. The National Oceanic and Atmospheric Administration numbers active regions consecutively as...

Spectacular Stellar Landscape Painted With Young Stars
2013-11-13 13:50:28

[ Watch The Video: Zooming in on the Star Cluster NGC 3572 ] ESO Astronomers at ESO have captured the best image so far of the curious clouds around the star cluster NGC 3572. This new image shows how these clouds of gas and dust have been sculpted into whimsical bubbles, arcs and the odd features known as elephant trunks by the stellar winds flowing from this gathering of hot young stars. The brightest of these cluster stars are much heavier than the Sun and will end their short...

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
2012-04-25 09:55:47

The Astronomy and Astrophysics Review is a peer-reviewed scientific journal published quarterly by Springer Science Business Media. The editor-in-chief is Thierry Courvoisier. It was first published in April 1989. The journal covers all areas of astronomy and astrophysics, including cosmic ray physics, studies in the solar system, astrobiology, developments in laboratory or particle physics relevant to astronomy, instrumentation, computational or statistical methods with specific...
