Data from the Hipparcos satellite in the 1990s enabled astronomers to establish many fundamental parameters of the Hyades.

The camera has enabled astronomers to survey more of the sky faster and with greater sensitivity in mapping dark-matter distribution.

An essential tool for enabling astronomers to advance beyond the stage reached by Bede was the astrolabe.

This measure enabled astronomers to calculate that the universe is expanding at the rate of 80 kilometers a second per megaparsec.

The rediscovery has enabled astronomers to calculate its orbit more precisely.

Some clusters of bright stars had been detected before, but the Hubble enabled astronomers to identify 40 clusters, each about 60 light-years in diameter.

Its camera was able to show the full disc of Quaoar, rather than just a pinpoint of light, enabling astronomers to measure its width.

Technological advances have enabled astronomers to overcome a number of the other past difficulties.

The error was well characterized and stable, enabling astronomers to optimize the results obtained using sophisticated image processing techniques such as deconvolution.

The telescope would have special optics to reduce the starlight by a factor of one billion, thus enabling astronomers to detect faint planets.
