Video Caption: A global team of astronomers, led by Harvard scientists, have captured an image of a black hole for the first time. The result of a massive, years-long effort by dozens of researchers, the Event Horizon Telescope focused on a pair of supermassive black holes – the one at the center of the Milky Way galaxy, known as Sagittarius A*, and a second that lies at the heart of an elliptical galaxy called M87. The work opens the door to allowing astronomers and physicists to put Einstein’s theories of gravity and general relativity to the test under the most extreme conditions in the universe.
PARIS (ESA PR) — Europe’s Galileo satellite navigation system – already serving users globally – has now provided a historic service to the physics community worldwide, enabling the most accurate measurement ever made of how shifts in gravity alter the passing of time, a key element of Einstein’s Theory of General Relativity.
With ATV Johannes Kepler in space and ATV Edoardo Amaldi almost built, the next Space Station supply craft coming off the production line has been named after the most famous scientist of all time: Albert Einstein. Launch is expected in early 2013.
With relativity and E=mc2, Albert Einstein is a major icon of 20th century science.
His theories have been stringently tested in space and his work is used to guide spacecraft to other planets – and now he will fly into orbit. ESA has decided to name the fourth Automated Transfer Vehicle (ATV) after Albert Einstein.
ATVs are an essential contribution by Europe for supplying and maintaining the International Space Station. (more…)
