" explains Laurent Brouard, Euclid Airbus project leader. “To meet their expectations, the mirrors inside the telescope are critical components. To give you an idea, one of the mirrors has been polished for three years and all the mirrors are aligned with each other to the nearest micron.”...
Hubble Space Telescope, the first sophisticated optical observatory placed into Earth’s orbit. Some of its many triumphs included the Hubble Deep Field, a photograph of about 1,500 galaxies revealing galactic evolution, and the discoveries of Hydra and
WhenGalileo Galileifirst turned a spyglass to the heavens in 1610, he had trouble making out the rings of Saturn that are visible in inexpensive telescopes today. Advances in optics eventually improved scientists' views of the planets, stars and distant galaxies, butEarth's atmospherestill blocked ...

Close behind are the twin Keck telescopes at Mauna Kea in Hawaii, which each have a diameter of 10 meters (33 feet). Their discoveries include refining the Andromeda galaxy's size and nabbing the first picture of an exoplanet system. ...
题目Telescopes(望远镜)have come a long way since the first ones were invented early in the 17th century.Traditional telescopes allow astronomers to view objects in space thanks to the visible(看得见的)light those objects emit(发出),or reflect.However,for modern telescopes,any ...

The AU Mic disk is located 32 light-years away in the Microscopium constellation. The star is about 23 million years old, so planet formation has already ceased around the star — since that process usually takes less than 10 million years, according to the researchers. Other telescopes have...
