Green Pea Galaxies Could Offer Astronomers An Understanding Of The Early Universe
2013-04-03 16:49:59

University of Michigan The rare Green Pea galaxies discovered by the general public in 2007 could help confirm astronomers' understanding of reionization, a pivotal stage in the evolution of the early universe, say University of Michigan researchers. Reionization occurred a few hundred million years after the Big Bang as the first stars were turning on and forming the first galaxies. During this period, the space between the galaxies changed from an opaque, neutral fog to a transparent...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online When we talk about the vacuum of space, we imagine a complete lack of matter — a cold void, dark, and absent of all energy. Over the last century, however, physicists have come to realize that the emptiness of space is anything by empty. On the macro scale, the vacuum of empty space may appear to lack matter and energy as we normally think of it. But when we look closely, and begin to examine the quantum...

Lee Rannals for redOrbit.com — Your Universe Online Using technologies contributed by NASA, the European Space Agency's (ESA) Planck space mission has provided the most accurate and detailed map made of the oldest light in the Universe. Results from Planck are giving a more detailed look into our Universe's history than ever before. The map suggests that the Universe is expanding more slowly and is 100 million years older than scientists previously thought. The data also shows...

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...
