Using a map of more than 4,000 luminous quasars in the distant universe, scientists from the Sloan Digital Sky Survey (SDSS-II) have shown that these brilliant beacons are strongly clumped, with huge quasar superclusters separated by vast stretches of empty space.

Chandra X-Ray Observatory -- A NASA Chandra X-ray Observatory image has revealed a complex of several intergalactic hot gas clouds in the process of merging.     The superb Chandra spatial resolution made it possible to distinguish individual galaxies from the massive clouds of hot gas...

Those who are involved in popularizing astronomy are asked certain questions time and again.&nbsp; One of these is 'How many stars are there?' Only when one is blessed with a rare glimpse of a star-spangled sky with its myriad luminaries, can we understand why this question occurs.&nbsp; Special computer analysis can readily answer the question.&nbsp;

Hubble's still got it In a galaxy far, far away, a period of unusually intense star formation is underway. Thousands upon thousands of new stars are blazing into life, as a starburst rips through the galaxy NGC 4449.â¦

Several dozen baby galaxies have turned up in galactic retirement communities near the Milky Way, new observations reveal. The objects resemble primitive galaxies from the early universe and may shed light on what triggers galaxies to form.

Scientists want Internet users to help them sort through an unusual digital photo album: pictures of about 1 million galaxies. In a Web statement Wednesday, astronomers asked for volunteers to help classify the galaxies, identifying them as either elliptical or spiral, and noting, where possible, in which direction they rotate.

Beyond snapping extraordinary pictures of faraway nebulas, the revolutionary Hubble Space Telescope has completely transformed our view of the universe since it was launched in 1990. By capturing the clearest, deepest images of the cosmos ever, Hubble has shed light on some long-standing mysteries perplexing scientists-while uncovering far deeper ones that have yet to be solved.

Outdoing Hubble, from the ground Astronomers working at the Palomar observatory have taken some of the clearest ever pictures of space. A US and UK team of stargazers have taken advantage of new adaptive optics technology to out-do even the Hubble Space Telescope for sharpness.â¦

This is the third article in a series of four articles each with a separate explanation of different quantum phenomena. Each article is a piece of a mosaic, so every one is needed to understand the final explanation of the quantum astronomy experiment we propose, possibly using the Allen Telescope Array and the narrow-band radio-wave detectors being build by the SETI Institute and the University of California, Berkeley.

Observing the image of a faint object that lies close to a star is a demanding task as the object is generally hidden in the glare of the star. Characterising this object, by taking spectra, is an even harder challenge.
