Hubble And VLT Data Reveals Details Of An Early Galaxy
2013-07-03 04:39:20

Lee Rannals for redOrbit.com - Your Universe Online Researchers have published details, including size, mass and content of elements, of an early galaxy in the scientific journal Monthly Notices of the Royal Astronomical Society. Galaxies from the early universe were much different than those found today. The team's new detailed study using the European Space Observatory's Very Large Telescope (VLT) and NASA's Hubble Space Telescope allows scientists to peer into one of the ancient...

Pulsating White Dwarf Discovered By UT Astronomers
2013-06-20 12:47:40

Lee Rannals for redOrbit.com - Your Universe Online A group of astronomers have discovered pulsations from the crystallized remnant of a burnt-out star. The researchers recently reported in The Astrophysical Journal Letters that they were able to use the 2.1-meter Otto Struve Telescope at the University of Texas McDonald Observatory to take a look at the white dwarf GD 518 and discover the pulsations. This finding will allow scientists to see below the star's atmosphere and into its...

Evidence Of New Phase In Neutron Stars Discovered
2013-06-14 13:48:03

Lee Rannals for redOrbit.com — Your Universe Online University of Alicante researchers have discovered the first evidence of a new phase in neutron stars. The scientists wrote in the journal Nature Physics that they have detected what may be the first observational evidence of existence of a new exotic phase of matter in what is known as the "inner crust" of neutron stars, or pulsars. "This may be the first observational evidence of existence of the phase of nuclear...

Nearby Flare Star Gives Burst Of Light
2013-06-14 12:17:36

Brett Smith for redOrbit.com - Your Universe Online Within a span of three minutes, a star in the Usra Major constellation less than 16 light-years from Earth gave off a massive flare, making the object 15 times brighter than normal, according to a new report in the journal Astrophysics. The star, known as WX“¯UMa, is a so-called flare star, a class of stars which can become 100 times or more brighter within a few seconds or minutes. These flares appear to be randomly...

Watch the video "Cosmography of the Local Universe" John P. Millis, PhD for redOrbit.com — Your Universe Online Visualizing the Universe is quite difficult. For one, the cosmos is enormous, far beyond the dimensions the human mind can comprehend. However, there is also the technical problem that we usually see images of the Universe as a two-dimensional image or map. Without the benefit of depth, we can´t truly appreciate the scale, orientation, and distribution of matter in...

Data Supports Cold Model Dark Matter
2013-06-13 15:54:45

John P. Millis, PhD for redOrbit.com — Your Universe Online Scientists continue the search to identify the nature of dark matter that seems to pervade the Universe. Since by its very nature it does not interact well — or perhaps at all — with electromagnetic radiation, direct detection of this mysterious form of matter has proven elusive. Despite this obstacle, astronomers have become convinced of its existence because of how it can be ℠seen´ to interact...

Euclid Dark Matter Mission Now In Development
2013-06-11 13:13:58

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA's) Euclid module under development in France will be helping to explore dark energy and dark matter in the universe. Euclid will be launching in 2020 to help scientists better understand the evolution of the Universe since the Big Bang and its present accelerating expansion. Dark matter is invisible to normal telescopes, making it hard to study. However, the elusive subject plays a vital role in...

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. Credit: NASA/Wikipedia What is Cosmology? I once commented to an acquaintance that I was fascinated by the field of Cosmology, and mused that if I had more time, I...

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...
