This new Hubble cast episode takes a detailed look into the refined Pointing Control System that allows Hubble to keep its gaze into the Universe firm and steady.
The NASA/ESA Hubble Space Telescope is one of the most sophisticated telescopes in the world. But even Hubble cannot uncover all secrets of the Universe on its own. This new Hubble cast focusses on discoveries astronomers made using Hubble and other telescopes, both in space and on the ground, in a scientific teamwork.
On 18 April 2019 Hubble is celebrating its 29th year in space. For this anniversary NASA and ESA dedicated a small amount of its precious observation time to take a look at the beautiful Southern Crab Nebula. This beautiful nebula is created by the ejected material of a red giant, which is in close interaction with a white dwarf star.
On 24 April 1990 the NASA/ESA Hubble Space Telescope was sent into orbit aboard the space shuttle Discovery, the first space telescope of its kind. It offered a new view of the Universe and has, for 30 years, reached and surpassed all expectations, beaming back data and images that have changed scientists’ understanding of the Universe .
Right after the Universe started with what scientist call the Big Bang, the cosmos was dark. Only the first stars created millions of years later brought light. These first stars and their radiation drastically changed the Universe during what is known as the epoch of reionisation.
