However, such a simple task becomes increasingly hard as astronomers attempt to count the more distant and fainter galaxies.

The inset is an image of an extremely faint and distant galaxy that existed only 400 million years after the big bang.

The faint radiation was visible thanks to a fortuitous cosmic alignment: The light from the distant quasar is amplified by the gravity of a much closer, invisible galaxy.

But beyond redshift 0.7 (roughly six billion light years distant), galaxies become fainter and more difficult to see.

Looking into the distant, early universe, we would expect dwarf galaxies to be numerous but also too faint to see.

Distant blasts could also help pinpoint the locations of faint GRB host galaxies that could be detected by space telescopes like the soon - to - be-refurbished Hubble Space Telescope or NASA's infrared James Webb Telescope, which is set to launch in 2013.

Together, the telescopes create a virtual dish 9000 kilometers wide that can detect the faintest radio emissions from distant galaxies.

The imaging data demonstrated that these sources are strongly lensed by foreground galaxies, which increases their apparent luminosities by a factor of ~ 10, which translates to a savings in telescope time of ~ 100, and allows such distant and intrinsically faint objects to be more easily detected.

Researchers were able to confirm characteristics of the Little Cub galaxy using Keck Observatory's Low Resolution Imaging Spectrograph, a faint - light instrument capable of taking spectra and images of the most distant known objects in the universe.

The gravitational lensing can also sometimes magnify the light of an otherwise too - faint, very distant galaxy enough for us to see it — a bonus natural telescope!

Unexpectedly faint Type 1a supernovae in distant galaxies led to the 1998 discovery of the accelerating expansion of the universe, on account of dark energy.

Hubble's latest discovery of 250 faint galaxies — formed 600 million to 900 million years after the Big Bang — in the early universe using three galaxy clusters to magnify the light given off by these distant objects.

«You can see bulges in distant galaxies, but you can not resolve the very faint stars, such as the white dwarfs.

Galaxy clusters enable us to see fainter light from galaxies in the distant universe.

The HDF observation was designed to detect very faint light from the most distant galaxies Hubble can observe.

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.

This five - ton instrument was designed to study the most distant, faintest galaxies, said UCLA physics and astronomy professor Ian McLean, co-project leader on MOSFIRE and director of UCLA's Infrared Laboratory for Astrophysics.

In faint, distant galaxies, the task is dramatically more difficult, but COSMOS - 1908 was one case for which Sanders was able to apply the «robust» method commonly applied to nearby galaxies.

Knowing the abundance of oxygen in the galaxy called COSMOS - 1908 is an important stepping stone toward allowing astronomers to better understand the population of faint, distant galaxies observed when the Universe was only a few billion years old, Shapley said.

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).

RESEARCHERS HAVE SOLVED a 60 - year - old mystery regarding the origin of the heaviest elements in nature, conveyed in the faint starlight from a distant dwarf galaxy.

Unfortunately, however, no single SFR estimator is universally available or even applicable in all circumstances: the numerous galaxies found in deep surveys are often too faint (or too distant) to yield significant detections with most standard SFR measures, and until now there have been no global, multi-band observations of nearby galaxies that span all the conditions under which star - formation is taking place.

It takes highly sensitive (expensive) cameras to capture the faint light of, say, a distant galaxy.
