WASHINGTON, April 24, 2014 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope have applied a new image processing technique to obtain near-infrared scattered light photos
An image of a galaxy cluster taken by the NASA/ESA Hubble Space Telescope gives a remarkable cross-section of the Universe, showing objects at different distances and stages in cosmic history.
Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away -- 10 times farther than previously possible.
WASHINGTON, April 10, 2014 /PRNewswire-USNewswire/ -- Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away -- 10 times
WASHINGTON, April 3, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and
Last week researchers from around the world gathered at the Accademia dei Lincei in Rome for the Science with the Hubble Space Telescope IV conference.Tim Otto Roth revealed a new artwork, Heaven’s Carousel, inspired by Hubble’s work on the accelerating expansion of the Universe.
WASHINGTON, March 17, 2014 /PRNewswire-USNewswire/ -- In celebration of the 24th anniversary of the launch of NASA's Hubble Space Telescope, astronomers have captured infrared-light images of
WASHINGTON, March 6, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has recorded the never-before-seen break-up of an asteroid into as many as 10 smaller pieces.
Scientists using the NASA Hubble Space Telescope found that the Large Magellanic Cloud (LMC) completes a rotation every 250 million years. The team used Hubble to measure the average motion of hundreds of individual stars in the nearby galaxy, which is located about 170,000 light-years away from Earth.
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...
- Having no light.
- Of or relating to the region of a body of water that is not reached by sunlight and in which photosynthesis is unable to occur.
