Beyond Earth: Telescopes In Space

Hubblecast 24: Beyond Earth – Telescopes In Space. There’s no better place for a telescope than space itself. Above the Earth’s atmosphere observations are no longer hampered by air turbulence, so telescopic images of distant stars and galaxies are razor-sharp. Unlike a ground-based telescope, an instrument in Earth orbit can operate twenty-four hours a day and reach every part of the sky. Observing from space also makes it possible to study types of radiation that are otherwise absorbed by the atmosphere. Little wonder that the Hubble Space Telescope has made so many contributions to astronomy. And Hubble is not alone – more than 100 space observatories have been launched since the 1960s.
