This is the first image astronomers have captured of a supermassive black hole big enough to swallow stars at the centre of a distant galaxy. Nothing that gets too close to the monstrous gravitational vortex can ever escape – not even light. But at the “point-of-no-return” precipice around its edge – the boundary scientists call the Event Horizon – hot gas, matter and radiation rage in a swirling eddy. While a black hole itself is by its nature invisibly dark, astronomers can observe the Event Horizon maelstrom with sufficiently powerful instruments. The image of the supermassive black hole at the core of galaxy M87 was obtained by … [Read more...] about Black hole ‘Event Horizon’ image captured for first time
Explain black holes
By Will Dunham WASHINGTON (Reuters) - An international scientific team is expected on Wednesday to unveil a landmark achievement in astrophysics - the first photo of a black hole - in a feat that will put to the test a pillar of science: Albert Einstein's theory of general relativity. Black holes are phenomenally dense celestial entities with gravitational fields so powerful no matter or light can escape, making them extraordinarily difficult to observe despite their great mass. News conferences are set in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo to disclose a "groundbreaking result" from the Event Horizon Telescope (EHT) project, begun in 2012 to directly observe the immediate environment of a black hole using a global network of telescopes. A black hole's event horizon is the point of no return beyond which anything - stars, planets, gas, dust and all forms of electromagnetic radiation - gets swallowed into oblivion. The project targeted two supermassive black … [Read more...] about Scientists expected to release landmark image of black hole
By Will Dunham WASHINGTON (Reuters) - Scientists are expected to unveil on Wednesday the first-ever photograph of a black hole, a breakthrough in astrophysics providing insight into celestial monsters with gravitational fields so intense no matter or light can escape. The U.S. National Science Foundation has scheduled a news conference in Washington to announce a "groundbreaking result from the Event Horizon Telescope (EHT) project," an international partnership formed in 2012 to try to directly observe the immediate environment of a black hole. Simultaneous news conferences are scheduled in Brussels, Santiago, Shanghai, Taipei and Tokyo. A black hole's event horizon, one of the most violent places in the universe, is the point of no return beyond which anything - stars, planets, gas, dust, all forms of electromagnetic radiation including light - gets sucked in irretrievably. While scientists involved in the research declined to disclose the findings ahead of the formal announcement, … [Read more...] about In astrophysics milestone, first photo of black hole expected

“It just felt like day care,” said one student. By Caroline Preston 11/10/2018 05:00 am ET PHILADELPHIA and GREENVILLE, Pa. — Back when he still lived with his family, when school was across the street from his home in West Philadelphia, Johnathan Hamilton used to plow through reading assignments and research religious questions online. He stumbled over fractions — math was always a struggle — but started getting into philosophy as an early teen. Then, at 15, his relationship with his parents grew violent, and Hamilton went to live in a city shelter for foster youth. When a bed became available at a residential facility in suburban Glenmoore, Pennsylvania, run by the nonprofit Devereux Foundation, Hamilton was sent to live there. For roughly nine months, he went to school on the grounds of the facility — and he says it was mostly lost time. Classes were full of kids of different ages. The material he was assigned seemed many grade … [Read more...] about How Schools For Kids In Foster Care Act As ‘Educational Black Holes’
