A team of scientists led by the University of Hertfordshire captured the event using the new 20 million euro William Herschel Telescope Enhanced Area Velocity Explorer (Weave) wide-field ...

A 7 foot telecope similar to this one was used by William Herschel to sweep the heavens and in the spring of 1781from his garden in Bath he first observed the planet Uranus. He made the telescope ...

Abstract: We have analysed short-exposure high-resolution images obtained on the William Herschel Telescope (WHT), Big Telescope Azimuthal (BTA) and Canada–France–Hawaii Telescope (CFHT) in order to ...

Jonathon Amos follows the engineers and astronomers who are working on the biggest telescope ever sent to space, in one of the most important missions in the history of European spaceflight ...

The Herschel Space Observatory is ESA's far-infrared space telescope. Imperial College astrophysicists have been involved with this project since its inception and are now reaping the benefits of this ...

Abstract: We have installed a Shack-Hartmann wavefront sensor at the William Herschel Telescope. The sensor has 8 × 8 subapertures and operates at frame rates up to 865 Hz. It is used to monitor those ...

We have developed a method for accurately measuring the polarization of altitude‐azimuth mounted telescopes by observing bright nearby stars at different parallactic angles, and we find that the ...

Several of our academics use the William Herschel Telescope (WHT) at El Roque de Los Muchachos Observatory in La Palma. At 4.6m in diameter it is the second largest in Europe and despite being of ...
