This new Hubble image - One among the largest ever produced with the Earth-orbiting observatory - shows gives the most detailed view so far of the entire Crab Nebula ever made. The Crab is arguably the single most interesting object, as well as one of the most studied, in all of astronomy. The image is the largest image ever taken with Hubble’s WFPC2 workhorse camera.Space 5
N90 is located in the wing of the Small Magellanic Cloud, in the constellation of Tucana, approximately 200,000 light-years away from the Earth. Its proximity makes it an exceptional laboratory to perform in-depth studies of star formation processes and their evolution in an environment close to that in the early Universe. Dwarf galaxies such as the Small Magellanic Cloud, with small numbers of stars compared to our own Milky Way, are considered to be the primitive building blocks of larger galaxies. The study of star formation within this dwarf galaxy is particularly interesting to astronomers because its primitive nature means that it lacks a large percentage of the heavier elements that are forged in successive generations of stars through nuclear fusion.Hubble creates 3-D map of 'Dark Matter'
The Hubble Space Telescope has helped an international team of astronomers create a three-dimensional map of 'dark matter' that provides the first direct look at the large-scale distribution of dark matter in the universe.
Dark matter is an invisible form of matter that accounts for most of the universe's mass, and according to the researchers, the map provides the best evidence yet that normal matter, largely in the form of galaxies, accumulates along the densest concentrations of dark matter. According to the research team, the map, which stretches halfway back to the beginning of the universe, shows how dark matter has grown increasingly "clumpy" as it collapsed under gravity.
It also reveals a loose network of filaments that grew over time and intersected in massive structures at the locations of clusters of galaxies, the researchers said.
Richard Massey and Nick Scoville from the California Institute of Technology, who presented the findings at the 209th meeting of the American Astronomical Society in Seattle, Washington, said the 3-D map was a milestone, that would help astronomers take the study of dark matter in the universe from the level of "inference to direct observation".
Previous studies of dark matter were based largely on numerical simulations of the expected evolution of large-scale structure, whereas this study showed that evolution was driven by the gravitational attraction of dark matter, they said.
According to the two, the new maps of dark matter and galaxies will also provide critical observational underpinnings to future theories for how structure formed in the evolving universe under the relentless pull of gravity.
"It's reassuring how well our map confirms the standard theories for structure formation." said Massey.
"Dark matter is the 'scaffolding' inside of which stars and galaxies have been assembled over billions of years. Theories suggest the universe transitioned from a smooth distribution of matter into a sponge-like structure of long filaments. Mapping dark matter's distribution in space and time is fundamental to understanding how galaxies grew and clustered over billions of years," he said.
"Tracing the growth of clustering in the dark matter may eventually also shed light on dark energy, a repulsive form of gravity that influences how dark matter clumps," he added.
For creating the map, Hubble photographed 575 slightly overlapping views of the universe using the Advanced Camera for Surveys' (ACS) Wide Field Camera onboard the telescope.
The European Southern Observatory's Very Large Telescope in Chile, and the Subaru telescope in Hawaii obtained a further 1000 hours of observations of thousands of galaxies' spectra.
Finally, a study of the hot gas in the densest galaxy clusters was imaged in X-rays by the ESA's XMM-Newton telescope and the distances accurately determined through their spectral redshifts to arrive at the map.

Since the launch of the first artificial satellites in the 1950s thousands of views of the earthhave been obtained from space. Althogh such images can give initial impression of a self-contained ball of light and coloure floating in a dark void, they also make us realize that our planet existswithin a context.

This is beautiful isn't it. Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies the young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is featured in this Hubble image of the region. Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies the young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is featured in this Hubble image of the region.At the estimated distance of the Small Magellanic Cloud, the picture spans about 200 light-years, but a tantalizing assortment of background galaxies are also visible in the sharp Hubble view. The background galaxies are hundreds of millions of light-years or more beyond NGC 602.

This is a cats eye Nebula in space. Three thousand light-years away, the Cat's Eye Nebula, a dying star throws off shells of glowing gas. This image from the Hubble Space Telescope reveals the nebula to be one of the most complex planetary nebulae known. In fact, the features seen in the Cat's Eye are so complex that astronomers suspect the bright central object may actually be a binary star system.Thursday, January 11, 2007

Parthenon - temple of Athena Parthenos , Greek goddess of wisdom, on the Acropolis in Athens. The Parthenon was built in the 5th century BC, and despite the enormous damage it has sustained over the centuries, it still communicates the ideals of order and harmony for which Greek architecture is known.Architecture in ancient Greece:
