NASA X-Ray Observatory Reveals Magnetars More Common Than Thought
2013-05-24 14:42:15

Lee Rannals for redOrbit.com — Your Universe Online NASA's Chandra X-ray Observatory has revealed that some of the most extreme objects in the universe may be more common than previously thought. Magnetars are the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation. When a massive star runs out of fuel its core collapses to form a neutron star. Most neutron stars spin rapidly, but a small fraction have a relatively low spin rate while also...

Blowing Bubbles: The Evolution And Disappearance Of Foamy Bubbles
2013-05-10 05:46:28

[ Watch the Video: Evolution of a Bubble Cluster ] redOrbit Staff & Wire Reports - Your Universe Online Researchers at the University of California, Berkeley, have mathematically described the successive stages in the complex evolution and disappearance of foamy bubbles, something that could help in modeling industrial processes in which liquids mix, or in the formation of solid foams such as those used to cushion bicycle helmets. The mathematicians applied their equations to...

Pear Shaped Atomic Nuclei
2013-05-09 11:28:49

Brett Smith for redOrbit.com - Your Universe Online According to a study in the journal Nature, a team of international scientists has found the first ever direct evidence of pear-shaped atomic nuclei. Bizarre pear-shaped nuclei could be the key to understanding one of the great mysteries of the universe: the reason for the Big Bang´s creation of a massive imbalance between matter and antimatter. "If equal amounts of matter and antimatter were created at the Big Bang, everything...

Evolution Of Black Holes Compared To Evolution Of Flight
2013-05-07 06:19:35

[ Listen to the Podcast Series: How Stars Die And Black Holes Form ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Scientists have debated the merits of the anthropic principle — the notion that the universe is somehow fine-tuned for life, or vice versa — and its variants for decades. The search to understand the nature and evolution of the universe is what plagues the fields of cosmology and astrophysics. Are we here because we happened upon a...

New Image Of Betelgeuse Reveals Hot Spots
2013-04-24 19:23:35

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have snapped a very detailed image of the outer atmosphere of the red supergiant Betelgeuse. This star is the nearest red supergiant to Earth, easily visible to the unaided eye sitting on the top left shoulder of Orion the Hunter. Betelgeuse is about 1,000 times larger than our Sun and lies about 650 light years away from Earth. Astronomers took a new image with the e-MERLIN radio telescope array operated from the...

Black Holes Can Help Determine The Universe's Rate Of Expansion
2013-04-23 04:48:33

Alan McStravick for redOrbit.com - Your Universe Online In 2011, the Nobel Prize for Physics was awarded to a trio of researchers. Adam Riess, Saul Perlmutter and Brian Schmidt were able to determine that the speed and scope of the expansion of the universe is not so uniform as once believed. This simple discovery threw the whole prospect of dating and measuring time in galaxies far from our own. However, this week saw a multi-national collaboration come together to detail just how we...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

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...

Lyra Constellation -- Lyra (the lyre) is a prominent, although fairly small, northern constellation. It was one of Ptolemy's 48 constellations, and also counts among the modern 88 constellations. Its brightest star is Vega (Alpha Lyrae), which together with Altair (Alpha Aquilae) and Deneb (Alpha Cygni) forms the large asterism known as the Summer Triangle. Beta Lyr is a half separated (i.e. one of the stars reached its Rochevolume) eclipsing binary of a cream-white colour. The...

Cygnus Constellation -- Cygnus (the swan) is a northern constellation. It was one of Ptolemy's 48 constellations, and is also one of the 88 modern constellations. Because of the pattern of its main stars, it is sometimes called the Northern Cross (in contrast to the Southern Cross). The bird extends over the summer Milky Way, appearing to fly south. Notable features Cygnus contains several bright stars. Deneb, α Cygni, is an extremely brilliant star, very prominent despite...

Centaurus Constellation -- Centaurus (the centaur) was one of the 48 constellations listed by Ptolemy, and counts also among the 88 modern constellations. A constellation of the southern hemisphere, mentioned by Eudoxus (4th century B.C.) and Aratus (3rd century B.C.), Ptolemy catalogued thirty-seven stars in it. It contains Proxima Centauri, the red dwarf that is the nearest known star (other than the Sun) to Earth, as well as Alpha Centauri, which is a double star to which Proxima...
