Space Slinky Video Compiled From Hubble Images
2013-08-23 04:04:14

[ Watch the Video: Hubble Takes Movies of Space Slinky ] redOrbit Staff & Wire Reports - Your Universe Online Astronomers are hoping to gain new insight in the role that black holes play in galaxy evolution thanks to a new series of time-lapse movies compiled from over a decade’s worth of observations from NASA’s Hubble Space Telescope. The video footage shows what experts have dubbed a “space slinky” – a 5,000 light-year-long jet of superheated gas being ejected from a...

Hubble Explores Origins Of Galaxies
2013-08-15 11:29:11

John P. Millis, PhD for redOrbit.com - Your Universe Online One of the major astronomical advancements of the 20th century was the ability to study in great detail the galaxies that make up our Universe. Instruments like the Hubble Space Telescope (HST) have brought a level of resolution that has allowed us to trace the history and evolution of galactic dynamics. Currently, galaxies are classified by the Hubble Sequence – a system whereby galaxies are grouped by their sizes, shapes,...

Holland Ford Receives NASA Award For Hubble Contributions
2013-07-19 09:31:35

HUBBLESITE Holland Ford, an astronomer at The Johns Hopkins University in Baltimore, Md., has received NASA's Distinguished Public Service Medal for his outstanding contributions to the Hubble Space Telescope. Ford attributes his success to the thousands of people in government, industry, science institutes, and academia who worked together to build and use Hubble to revolutionize our view of the universe. "What a privilege to be part of this great endeavor!" he says. The...

Mystery Of Nearby SS Cygni Star System Finally Resolved
2013-05-23 13:22:47

John P. Millis, PhD for redOrbit.com — Your Universe Online In 1990 the Hubble Space Telescope measured the distance to a nearby star system known as SS Cygni. Composed of a low-mass main sequence star and a compact object known as a white dwarf — a stellar remnant about the mass of our Sun, but compressed to the size of the Earth. The distance measured by Hubble puzzled scientists, as the measured brightness of the system was considerably higher than expected. If correct,...

Hubble Space Telescope Breaks Record For Furthest Supernova
2013-04-04 12:49:29

ESA/Hubble The NASA/ESA Hubble Space Telescope has broken the record in the quest to find the furthest supernova of the type used to measure cosmic distances. This supernova exploded more than 10 billion years ago (redshift 1.914), at a time the Universe was in its early formative years and stars were being born at a rapid rate. The supernova, designated SN UDS10Wil, belongs to a special class of exploding stars known as Type Ia supernovae. These bright beacons are prized by astronomers...

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...

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...
