By contrast, the 300-foot telescope at Green Bank could observe over a much wider angle of sky than most other radiotelescopes.

Ultraviolet and X-ray telescopes can observe highly energetic galactic phenomena.

In 1968, the telescope observed the coordinates of the recently discovered pulsar, confirming its existence and investigating the dispersion measure.

The telescope first observed two Apollo landing sites, where astronauts had found the glassy, oxygen-bearing minerals.

Its three telescopes will observe the emissions and their radiation afterglow, information scientists need to understand the explosions.

My telescopes can observe the spill mountains.

In sweeping the sky, the telescope observed enormous regions of intense X-ray energy associated with quasars.

The telescope only observes at night during good weather, using planets for calibration.

Second, a space-based telescope could observe infrared and ultraviolet light, which are strongly absorbed by the atmosphere.

The telescope observes the Sun for about 1.5 hours at sunrise and another 1.5 hours at sunset each day.
