Remarkable new image from the Hubble Space Telescope
The latest pictures include trademark Hubble visions – from colliding galaxies to exploding stars. Nasa says the orbiting telescope, regarded as one of the most important scientific tools ever built, should keep working until at least 2014. The Atlantis astronauts conducted five spacewalks, to install new instruments and thermal blankets, to repair two existing instruments, and replace the telescope’s gyroscopes and batteries. The main addition was the new Wide Field Camera 3. WFC3 will also allow Hubble to look deeper into space than ever before, to search for the very first stars to shine in the Universe.
The Butterfly Nebula captured with the new WFC3, The Wide Field Camera is the instrument that many astronomers suspect will deliver the really big discoveries in the remaining operational years. It will allow astronomers to carry out new studies of dark energy and dark matter.
The US space agency and its international partners plan now to concentrate their efforts on preparing a bigger and more capable observatory known as the James Webb Space Telescope (JWST).
