Monster Galaxy Found
2012-10-25 22:05:33

Lee Rannals for redOrbit.com — Your Universe Online A team of astronomers has grabbed an image of a huge elliptical galaxy with a core that is bigger than any seen before. The team used the Hubble Space Telescope to collect the image of the galaxy, which is about ten times the diameter of the Milky Way galaxy. The galaxy is a member of a class of galaxies with an unusually diffuse core filled without a concentrated peak of light around a central black hole. Viewing the core...

Generation X And Scientific Literacy
2012-10-24 04:03:13

April Flowers for redOrbit.com - Your Universe Online Researchers have found that less than half of Generation X adults can identify our own home in the universe, the spiral galaxy in which we reside. "Knowing your cosmic address is not a necessary job skill, but it is an important part of human knowledge about our universe and–to some extent–about ourselves," said Jon D. Miller, author of "The Generation X Report" and director of the Longitudinal Study of American Youth at...

Spitzer Helps Measure The Universe
2012-10-03 20:20:38

Lee Rannals for redOrbit.com — Your Universe Online NASA's Spitzer Space Telescope has allowed astronomers to make the most precise measurement yet of the rate at which our universe is expanding. This expansion rate, also known as the Hubble Constant, is critical for understanding the age and the size of the universe. In the latest research, Spitzer took advantage of long-wavelength infrared light to make its new measurement. The newly refined value for the Hubble Constant,...

Hubble Reveals Deepest View  Ever Of The Universe
2012-09-26 05:09:28

April Flowers for redOrbit.com - Your Universe Online Researchers using the Hubble Telescope have assembled a new and improved portrait of our deepest-ever view of the Universe. The eXtreme Deep Field (XDF) photo was compiled by combining ten years worth of NASA and ESA Hubble Space Telescope observations taken of a patch of sky within the original Hubble Ultra Deep Field. The Hubble Ultra Deep Field is a small area of space in the Fornax (The Furnace) constellation created using Hubble...

Hubble Supernova Image From Galaxy NGC 5806
2012-09-02 07:40:28

redOrbit Staff & Wire Reports - Your Universe Online NASA recently released this Hubble Space Telescope image of a supernova that the telescope took while studying a spiral galaxy in the constellation Virgo back in 2005. The supernova, dubbed SN 2004dg, was located in the galaxy NGC 5806, which had been selected as part of a study into supernovae because the Hubble archive already contained high resolution images of the galaxy that had been taken prior to the 2004 explosion of the...

Hubble Images Isolated Galaxy DDO 190
2012-08-18 06:55:57

redOrbit Staff & Wire Reports - Your Universe Online An image of an isolated galaxy located approximately nine million light years from the Milky Way has been captured using the Hubble Space Telescope, NASA officials announced on Friday. The picture features a relatively isolated, dwarf irregular galaxy known as DDO 190, which officials from the US space agency describe as relatively small and lacking in structure. The galaxy, which was identified and code named in honor of the...

Milky Way Destined For Head-On Collision
2012-06-05 03:18:55

[ Watch the Video ] NASA astronomers announced on May 31 that they can now predict with certainty the next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy. The Milky Way is destined to get a major makeover during the encounter, which is predicted to happen four billion years from now. It is likely the sun will be flung into a new region of our galaxy, but our Earth and solar system are in...

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...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
