The Hubble Space Telescope will devote an unprecedented amount of time over the next few years to documenting galaxy evolution in the early universe and to studying whether distant supernovae can be extremely reliable measures of distance across vast regions of the cosmos. In this ambitious new project, Hubble will image more than 250,000 distant galaxies in five directions, providing the first comprehensive view of the structure and assembly of galaxies over the first third of cosmic time....

Hubble shows that the beautiful spirals galaxies of the modern Universe were the ugly ducklings of six billion years ago. If confirmed, the finding highlights the importance to many galaxies of collisions and mergers in the recent past. It also provides clues for the unique status of our own galaxy, the Milky Way. Using data from the NASA/ESA Hubble Space Telescope, astronomers have created a census of galaxy types and shapes from a time before Earth and the Sun existed, up to the present...

Astronomers, using NASA's Hubble Space Telescope, have broken the distance limit for galaxies by uncovering a primordial population of compact and ultra-blue galaxies that have never been seen before. They are from 13 billion years ago, just 600 to 800 million years after the Big Bang. These newly found objects are crucial to understanding the evolutionary link between the birth of the first stars, the formation of the first galaxies, and the sequence of evolutionary events that resulted in...

Using the recently updated Hubble Space Telescope (HST) two teams of UK astronomers have identified galaxies which are likely to be the most distant yet seen. The UK teams, one led by Andrew Bunker and Stephen Wilkins at the University of Oxford and the other by Ross McLure and Jim Dunlop at the University of Edinburgh, analyzed infrared images from the new Wide Field Camera 3 (WFC3) instrument on HST, installed during the most recent Space Shuttle servicing mission in May 2009. Infrared...

WASHINGTON, Nov. 20 /PRNewswire-USNewswire/ -- Following is the daily "Profile America" feature from the U.S. Census Bureau: (Logo: http://www.newscom.com/cgi-bin/prnh/20090226/CENSUSLOGO) FRIDAY, NOVEMBER 20: EDWIN HUBBLE Profile America -- Friday, November 20th. The town of Marshfield, Missouri, is celebrating the birthday of its most famous son today -- a man who opened the eyes of the world to the vastness and complexity of space. Edwin Hubble's groundbreaking observations...

When the crew of the Space Shuttle Atlantis released the Hubble Space Telescope to return to orbit, concluding the final astronaut mission to upgrade and repair Hubble, astronomy fans around the world rejoiced. Hubble, renewed and equipped with new cameras, would now return to its work of revealing the universe. But after the furor and high-profile feats of a servicing mission, Hubble sinks into silence. This time, a three-month hiatus will take place between the mission and any new images....

Whatever dark energy is, explanations for it have less wiggle room following a Hubble Space Telescope observation that has refined the measurement of the universe's present expansion rate to a precision where the error is smaller than five percent. The new value for the expansion rate, known as the Hubble constant, or H0 (after Edwin Hubble who first measured the expansion of the universe nearly a century ago), is 74.2 kilometers per second per megaparsec (error margin of...

A flare-up in a jet of matter blasting from a monster black hole is giving astronomers an incredible light show. The outburst is coming from a blob of matter, called HST-1, embedded in the jet, a powerful narrow beam of hot gas produced by a supermassive black hole residing in the core of the giant elliptical galaxy M87. HST-1 is so bright that it is outshining even M87's brilliant core, whose monster black hole is one of the most massive yet discovered. The glowing gas clump has taken...

A mysterious flash of light from somewhere near or far in the universe is still keeping astronomers in the dark long after it was first detected by NASA's Hubble Space Telescope in 2006. It might represent an entirely new class of stellar phenomena that has previously gone undetected in the universe, say researchers. Astronomers commonly observe intense flashes of light from a variety of stellar explosions and outbursts, such as novae and supernovae. Hubble discovered the cosmic flash on...

The U.S. space agency's Hubble Space Telescope is back in operation after malfunctioning last month. The Space Telescope Science Institute in Baltimore, which operates Hubble for the National Aeronautics and Space Administration, said NASA engineers succeeded in restoring the telescope's main camera to working order. The failure of the instrument delayed a planned space shuttle servicing mission to upgrade and repair the orbiting observatory. The institute said newly acquired images...

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...
