This involves taking advantage of distant, but cloesr, galaxies that lie between Earth and the quasar.

From 1969 to 1982, Mr. Collins served as Executive Vice President of American Quasar Petroleum Company.
Another company that has recognized the potential of the advanced energy sector is quasar energy group.
But it is not just the light from the distant quasar that carries information about the composition of the Universe.
For the first time, scientists working at the Hubble Space Telescope were able to directly observe a quasar accretion disc.

Using this technique, researchers were able to directly determine the temperatures at different parts of the quasar, and determine measurements of its size.

Changes in the way the light moves comes from the way gravity bends the light as it travels from the quasar towards Earth.

But this gas cloud, because it is so far away, about 40, 000 light years is still seeing the quasar, though we are not.
And so, what we believe in this case happened is there used to be an extremely luminous quasar right next to this gas cloud.
Just as in a container, molecules in an inter-galactic gas cloud absorb certain wavelengths and leave a pattern of dark lines on a quasar's spectrum.
In the quasar spectra, some of the dark lines were shifted slightly towards the red end of the colour spectrum and others towards the blue end.
The deviations are too small to be seen in any single quasar, but by averaging the results for 72 quasars the team claims to have secure statistical evidence.
Advanced and renewable energy projects like those championed by quasar and LEEDCo will continue to create jobs as they leverage natural resources and industrial supply chain capabilities already available.
That in turn enabled them to learn more about the properties of the matter in the quasar as it moves ever closer towards the event horizon of the black hole.

We can measure the wink of a quark and the glimmer of quasar, but to plumb the depths of the mind of a man or woman is still beyond our reach.
Astronomers say that the key to SDSS's success in quasar spotting is its recording of precision digital data in five colours, which allows researchers to easily distinguish quasars from more common faint stars.
Dr Webb's team found that, even after correcting for this red shift, the dark lines in the quasar spectra did not appear at the same wavelengths as they do in laboratories on earth.
Todd Boroson and Tod Lauer of the US National Optical Astronomy Observatory analysed some 17, 500 spectra from the Sloan Digital Sky Survey, and have now found just such a pair of emissions coming from a distant quasar.
It develops anaerobic digesters that convert organic waste into biogas used to generate electricity, heat, natural gas and motor vehicle fuel (CNG). quasar already operates eight facilities in Ohio, and several more are in process in the Buckeye State and elsewhere.
Chris Carilli, of the National Radio Astronomy Observatory in Socorro, New Mexico, points out that the quasar-based method to measure the ancient value of alpha is at least 30 years old, and has never before resulted in a value different from today's alpha.
