Toronto, April 10: Scientists working on the Event Horizon Telescope Collaboration will present a "ground-breaking result" from their collaborative project on April 10, according to a media advisory on their website.
The group is expected to release pictures of a black hole, the first images from their collaborative project which had eight radio observatories spanning the globe teaming up to capture data of the black hole Sagittarius A. Sagittarius A or Sgr A is at the centre of our galaxy, the Milky Way. It has a mass equivalent to about 4.1 million of our suns and is hence categorised as a “supermassive black hole”. There are so many black holes in the universe that it is impossible to get an accurate number with each one of varying size.
But how can telescopes capture the image of a Black Hole when as its concept implies it is nothing but a black hole? A black hole is identified by the particles around it as its gravitational pull brings in objects such as gas and dust of which some settle into an orbiting disk, with atoms jostling one another at extreme speeds. All that activity heats the matter white-hot, so it emits high-energy radiation which can then be captured by the telescopes, according to the explanation provided by sciencenews.org.
Hence the EHT’s image of the Sagittarius A is expected to capture the black hole’s shadow along with its accompanying disk of bright material. The EHT scientists will publish their findings after combining the data captured by eight radio telescopes around the world using Very-Long-Baseline-Interferometry, which essentially created a virtual telescope the same size as the Earth itself according to the European Southern Observatory, which is part of the EHT.
The EHTC press release said it will present its first results in multiple simultaneous press conferences around the world. Press conferences are scheduled to be held simultaneously in Brussels (in English), Lyngby (in Danish), Santiago (in Spanish), Shanghai (in Mandarin), Tokyo (in Japanese), Taipei (in Mandarin), and Washington D.C. (in English), starting at 13:00 Universal Time.
