MAGNIFYING THE COSMOS The light from a distant galaxy (lower right) is warped by the gravity of a closer, massive galaxy (bright blur in center).

Some research has been done to deduce the chemical makeup of very early galaxies, based on observations of very bright, distant galaxies, or of very old stars that formed in the early universe and are still around today, Hewitt said.

Quasars are bright cores of distant active galaxies.

Astronomers have discovered a bright galaxy that is the most distant one yet to be measured, Yale University announced today.

The huge mass of the cluster acts as a cosmic magnifying glass and enlarges even more distant galaxies, so they become bright enough for Hubble to see.

Such a smash - up with a red giant would unleash much more energy than the decimation of a comet, so would have to occur in a distant galaxy to avoid appearing brighter than what was observed.

The ideal background «lights» for such a study are quasars, which are very distant bright cores of active galaxies powered by black holes.

They are the locations of bright stars and other nearby objects that get in the way of the observations of more distant galaxies and are hence masked out in these maps as no weak - lensing signal can be measured in these areas.

The first clue that supermassive black holes exist was the discovery several decades ago of quasars — extremely bright objects in the centres of distant galaxies.

Quasars are young galaxies powered by massive black holes, extremely bright, extremely distant, and thus highly redshifted.

Rather than studying bright stars, the two students used Hubble Space Telescope data from 274 dwarf stars, which were serendipitously observed by the orbiting observatory while it was looking for the most distant galaxies in the early Universe.

«There's always been a concern that we've only found the brightest of the distant galaxies,» said Siana.

Eight bright X-ray sources located far beyond the galaxy at distances of hundreds of millions of light - years were observed with Chandra, which revealed that the X-rays from these distant sources are absorbed selectively by oxygen ions in the vicinity of our galaxy.

Many distant galaxies have supermassive black holes at their cores, and those black holes power «central engines» that produce bright emission.

Although it is close to the line of sight to the globular cluster M15, most astronomers had thought that this source of bright radio waves was probably a distant galaxy.

Click to Enlarge (JPEG / 138.4 KB) This schematic image represents how light from a distant galaxy is distorted by the gravitational effects of a nearer foreground galaxy, which acts like a lens and makes the distant source appear distorted, but brighter, forming characteristic rings of light, known as Einstein rings.

«We are using the massive amounts of dark matter surrounding galaxies half - way across the Universe as cosmic telescopes to make even more distant galaxies appear bigger and brighter.»

Astronomers also looked at how the light coming out certain of bright, distant galaxies, called quasars, filtered through these cobwebby strands.

With only a relatively minor change to the observing strategy, taking extra care to avoid extra glare from bright foreground light from the Earth, we enabled the Frontier Fields to see ever fainter and more distant galaxies than otherwise would have been possible.

Indeed, GRBs appear to emit produce even more energy than supernovae or even quasars (which are energetically bright accretion disks and bi-polar jets around supermassive black holes that are most commonly found in the active nuclei of some distant galaxies and possibly even in the pre-galaxy period after the Big Bang).

A new analysis of galaxy colors, however, indicates that the farthest objects in the deep fields must be extremely intense, unexpectedly bright knots of blue - white, hot newborn stars embedded in primordial proto - galaxies that are too faint to be seen even by Hubble's far vision — as if only the lights on a distant Christmas tree were seen and so one must infer the presence of the whole tree (more discussion at: STScI; and Lanzetta et al, 2002).

Subsequently, however, an even more distant quasar with a tentative redshift of z = 6.40 was announced on January 9, 2003, near the SDSS detection limit of a redshift of z ~ 6.5 for bright quasars, and other teams of astronomers detected even more distant, fast - star - forming irregular proto - galaxies, including: gravitationally - lensed HCM 6A behind galaxy cluster Abell 370 with a redshift of z ~ 6.56, which appears to be converting about 40 Solar - masses into stars annually; (PhysicsWeb; IFA press release; Hu et al, 2002, in pdf; and erratum); and the possible «superwind - galaxy» LAE J1044 - 0130 (Subaru press release; and Ajiki et al, 2002, in pdf).
