Sentences with phrase «much fainter objects»

Extreme adaptive optics also allows much fainter objects to be seen very close to a bright star.

So Anita Cochran of the University of Texas and her colleagues turned to the Hubble telescope's Wide Field / Planetary Camera, which can spot much fainter objects.

Not exact matches

We train our telescopes on small patches of sky for long spells, trying to drink in as much faint light from distant objects as possible.

All seven mirrors combined gather less than one - hundredth as much light as one 30 - foot - wide mirror, meaning they won't pull in the faintest objects in the sky.

Ground - based and orbiting telescopes employ exquisitely sensitive detectors to search for objects that are much farther away, and much fainter, than could have been detected just a few years ago.

The FOS examined fainter objects than the High Resolution Spectrograph (HRS), and could study these objects across a much wider spectral range — from the UV (1150 Angstroms) through the visible red and the near - IR (8000 Angstroms).

Redshift is a measure of how much the Universe has expanded since the light left a distant source and can only be determined for faint objects with a spectrograph on a powerful large telescope such as the Keck Observatory's twin 10 - meter telescopes, the largest on Earth.

Most of the objects you'll see in Disk Detective are much fainter than this!

This was necessary because if the telescope were not cooled down, its own thermal radiation at infrared wavelengths would swamp the much fainter radiation from astronomical objects.
