Astronomers have captured the first-ever image of a black hole, which is located in a distant galaxy known as ‘Messier 87’ (M87), through a network of 8 linked radio telescopes known as the Event Horizon Telescope (EHT) Collaboration. The black hole in the centre of M87 has a mass of more than six billion solar ..
Computer scientist Katie Bouman, who is still a graduate student at MIT has developed the algorithm to create the first image ever of a black hole. Katie has named the algorithm ‘CHIRP’ (Continuous High-resolution Image Reconstruction using Patch priors) which was needed to gather data from 8 radio telescopes across the world working under Event Horizon ..
An international team of more than 200 astronomers from 18 countries has published the first phase of a major new radio sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope in the journal Astronomy & Astrophysics. The survey discovered 3,00,000 hidden galaxies using radio astronomy in a tiny corner of the northern ..
SOFIA, the Stratospheric Observatory for Infrared Astronomy, is the largest airborne observatory in the world, capable of making observations that are impossible for even the largest and highest ground-based telescopes. It has the ability to produce a higher resolution image, three times higher in quality than those captured by other observatories. It is a joint ..
