Upgraded Arecibo radio telescope with subreflector

Upgraded Arecibo radio observatory. Aerial fisheye lens view of the Arecibo radio telescope, with its gregorian subreflector system newly installed in 1997. This largest radio telescope in the world is situated in a natural crater in the mountains of Puerto Rico. The new subreflector system with two mirrors is housed in a 90-tonne dome receiver seen suspended 130 metres above the fixed dish. It can send and receive signals to examine planets and asteroids & also analyse Earth's upper atmosphere. To scan the sky the dome is steered above the 305m dish. The upgrade includes a 16m high buffer screen around the dish and a new radar transmitter that increases Arecibo's power by 20 times

Supermassive black hole, artwork Featured Telescopes Radio Print

Supermassive black hole, artwork

Supermassive black hole. Artwork of an accretion disc of infalling material (orange) and a high-energy particle jet (blue) associated with a supermassive black hole at the centre of a galaxy. Black holes are formed when matter collapses to densities where gravity prevents light escaping. Supermassive ones can contain the mass of billions of stars. X-rays from the base of the jet illuminates the accretion disc, allowing studies such as those carried out by NASA's NuSTAR mission (Nuclear Spectroscopic Telescope Array). This allows calculations of the rate of rotation within the accretion disc, and the rate of spin of the black hole. Image published in 2013

Centaurus A galaxy, HST image

Centaurus A galaxy. Hubble Space Telescope (HST) image of the active galaxy Centaurus A, which is thought to house a massive black hole. Centaurus A is a large elliptical galaxy which collided with a smaller spiral galaxy millions of years ago, sparking a huge burst of starbirth activity. Large areas of young blue stars are seen on either side of the dark lane of dust. This dust is thought to be the remnant of the smaller galaxy which Centaurus A swallowed. Centaurus A is also a powerful emitter of radio waves powered by its black hole. It lies 10 million light years from Earth in the constellation Centaurus. Image taken in July 2010 with the Wide Field Camera 3 on the HST
