New Theory Explains Expansion Of Universe
2013-09-10 08:47:37

John P. Millis, PhD for redOrbit.com - Your Universe Online For the better part of a century the astronomical community has understood that the Universe is expanding, yet the exact nature of this expansion has been difficult to quantify. One extreme instance of this is the acceleration of galaxies receding from us billions of light-years away. But even looking closer to home, calculating the rate of expansion has proven difficult. Traditionally, scientists, measuring the recession...

Evolution Of Early Universe Successfully Simulated With Ultracold Big Bang Experiment
2013-08-29 10:22:39

University of Chicago Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago. “This is the first time an experiment like this has simulated the evolution of structure in the early universe,” said Cheng Chin, professor in physics. Chin and his associates reported their feat in the Aug. 1 edition of Science Express, and it will...

Zombie-Like Vortex Gives Final Push To Birth New Star
2013-08-21 14:06:17

Brett Smith for redOrbit.com - Your Universe Online For years, most astronomers have agreed on the basic steps that lead to star formation, except one – how a cloud of swirling gas can slow down enough to concentrate into something capable of nuclear fusion. A new study from the University of California, Berkeley has found evidence of “zombie vortices” within a gestating star leading to a final push that gives birth to a new star. According to prevailing theories, stars begin...

3D Map Of The Large-Scale Structure Of The Universe Released
2013-08-08 13:58:29

Subaru Telescope An international team led by astronomers from Kyoto University, the University of Tokyo and the University of Oxford has released its first version of a 3D map of the Universe from its FastSound project (Note 1), which is surveying galaxies in the Universe over nine billion light years away. Using the Subaru Telescope's new Fiber Multi-Object Spectrograph (FMOS, Note 2), the team's 3D map includes 1,100 galaxies and shows the large-scale structure of the Universe nine...

Cosmic Microwave Background Radiation Data Allows Furthest Look Back Through Time
2013-08-08 04:23:16

April Flowers for redOrbit.com - Your Universe Online The best way to solve a mystery, as any detective can tell you, is to revisit the scene where it began and look for clues. Scientists, searching for the mysteries of our universe, are trying to go back as far as they can to the Big Bang. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) conducted a new analysis of cosmic microwave background (CMB) radiation data to take the furthest look back yet. This look - 100...

Andromeda Galaxy Image Processed By The HSC Data Analysis Software
2013-08-06 11:44:39

Kavli Institute for the Physics and Mathematics of the Universe Today, researchers at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) released the first image of the Andromeda Galaxy (M31) processed with the data analysis software developed for the Subaru Telescope's Hyper Suprime-Cam (HSC). The HSC project's 'first light' was announced last week (A New View on the Origin of Dark Matter and Dark Energy - Image of M31 Heralds the Dawn of HSC). Researchers at...

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 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...
