Hubble Inspires New Technologies
2013-03-31 05:30:43

redOrbit Staff & Wire Reports - Your Universe Online Drawing inspiration from NASA´s Hubble Space Telescope, two different teams of researchers have developed both an easy-to-use, fully searchable 3D map of the universe and new technology that could improve the quality of laser eye surgery, various media outlets reported late last week. A Microsoft team collected data and images from Hubble and other similar instruments to create what has been dubbed the WorldWide Telescope...

Spiral Galaxy Messier 106 Has A Secret
2013-02-05 10:47:02

[ Video 1 ] | [ Video 2 ] | [ Video 2 ] NASA/ESA Hubble Heritage Team The NASA/ESA Hubble Space Telescope — with a little help from an amateur astronomer — has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years away, practically a neighbor by cosmic standards, Messier 106 is one of the brightest and nearest spiral galaxies to our own. Despite its appearance, which looks much like countless other galaxies,...

Hubble Space Telescope Snaps Image Of Large Magellanic Cloud’s Hidden Treasure
2013-01-17 07:37:54

[Watch Video 1] [Watch Video 2] Lawrence LeBlond for redOrbit.com - Your Universe Online The Large Magellanic Cloud (LMC), an irregular galaxy that shares some features with spiral galaxies, is known for its array of star-forming regions. One of those regions, LHA 120-N 11 (N11), captured by the Hubble Space Telescope, offers proof that the LMC is producing noticeable signs that stellar nurseries within are still hard at work. The LMC is in an ideal position for astronomers to study...

Distant Supernova Dates Back To 10 Billion Years
2013-01-10 08:09:44

April Flowers for redOrbit.com - Your Universe Online Have you ever wished for a time machine to be able to travel to the distant past? What about a "Wayback Television Set" that would allow you to watch an entire month of ancient prehistory in real time? Berkeley Lab´s David Rubin gave just such a scenario to attendees at the American Astronomical Society meeting this week when he unveiled the discovery of a striking astronomical object. Rubin announced a Type Ia supernova with...

Astronomers Discover 7 Primitive Galaxies
2012-12-13 08:30:25

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered seven primitive galaxies that formed more than 13 billion years ago, during the Universe's infancy. The find includes a candidate galaxy that could hold the record for the most distant galaxy ever found. Scientists made the new discoveries using the Hubble Space Telescope's Hubble Ultra Deep Field project, which aims to improve our understanding of the early Universe. Astronomers are looking back at...

NASA will hold a media teleconference at 2 p.m. EST Wednesday, Dec. 12, to discuss the latest findings from NASA's Hubble Space Telescope. Astronomers will report on recent observations of a previously unseen population of primitive galaxies that formed more than 13 billion years ago. The teleconference panelists are: -- Richard Ellis, astrophysicist, California Institute of Technology, Pasadena, Calif. -- Abraham Loeb, chair, Astronomy Department, Harvard University, Cambridge, Mass....

Andromeda Project Wants Your Help Searching For Star Clusters
2012-12-05 13:08:22

Lee Rannals for redOrbit.com - Your Universe Online A new project, named The Andromeda Project, is asking the public's help to search through Hubble Space Telescope images to identify star clusters and increase our understanding of how galaxies evolve. The new project is a collaboration between scientists at the University of Washington, the University of Utah and other partners, aiming to study thousands of high-resolution Hubble images. “It´s an amazing opportunity to...

Hubble Sets Dark Matter Record Straight
2012-11-29 19:24:08

Lee Rannals for redOrbit.com — Your Universe Online A new observation of Abell 520 using the Hubble Space Telescope has helped astronomers determine that the core of the galaxy cluster is not over-dense in dark matter after all. Astronomers earlier this year spotted an overabundance of dark matter in the heart of the galaxy cluster. This observation was puzzling because dark matter and galaxies should be anchored together. Scientists have evidence that dark matter is...

Cosmology -- area of science that aims at a comprehensive theory of the structure and evolution of the entire physical universe. Modern Cosmological Theories Present models of the universe hold two fundamental premises: the cosmological principle and the dominant role of gravitation. Derived by Hubble, the cosmological principle holds that if a large enough sample of galaxies is considered, the universe looks the same from all positions and in all directions in space. The second point...

Spiral Galaxy -- Among the galaxies, there are apparently three main categories, according to their appearance: the disk galaxies (`cosmic frisbies' according to P. Murdin, D. Allen, and D. Malin), consisting of a huge disk of stars and interstellar matter, which may form interesting patterns, the elliptical galaxies (`cosmic footballs') which are uniformly looking, ellipsoidal agglomerations of stars, and the irregular galaxies (`cosmic misfits') which cannot be integrated in this scheme....

Reflection Nebula -- In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. The distiction between these two types of nebulae was done by Hubble in 1922. They are usually blue because the scattering is more efficient for blue light...

Redshift -- Redshift is the phenomenon that the frequency of light when observed, under certain circumstances, can be lower than the frequency of light when it was emitted at the source. This usually occurs when the source moves away from the observer, as in the Doppler effect. More specifically, the term redshift is used for the observation that the spectrum of light emitted by distant galaxies is shifted to lower frequencies (towards the red end of the spectrum, hence the name) when...

Big Bang -- The Big Bang theory is the dominant theory in cosmology about the early development and current shape of the universe. According to this theory, the universe expanded rapidly starting 13.7 0.2 billion years ago. Extrapolating the history of the universe backwards using current physical models leads to a gravitational singularity, at which all distances become zero and temperatures and pressures become infinite. What this means is unclear and most physicists believe that this...
