Hace 2 días · A map of the Event Horizon Telescope observatories used in recent test observations at 0.87 mm of distant galaxies, to bump up its resolution. Credit: ESO/M. Kornmesser. This pilot experiment ...
Hace 5 días · The Event Horizon Telescope (EHT) Collaboration has conducted test observations achieving the highest resolution ever obtained from the surface of the Earth, by detecting light from the centers of distant galaxies at a frequency of around 345 GHz.. When combined with existing images of supermassive black holes at the hearts of M87 and Sgr A at the lower frequency of 230 GHz, these new results ...
Hace 2 días · The defining feature of a black hole is the appearance of an event horizon—a boundary in spacetime through which matter and light can pass only inward towards the mass of the black hole. Nothing, not even light, can escape from inside the event horizon.
Hace 3 días · The singularity constitutes the center of a black hole, hidden by the object’s “surface,” the event horizon. Inside the event horizon, the escape velocity exceeds the speed of light so that not even rays of light can escape into space.
Hace 5 días · Credit: ESO/M. Kornmesser. The Event Horizon Telescope has achieved unprecedented high-resolution observations from Earth by utilizing the 345 GHz frequency, offering more detailed and color-enhanced images of black holes. This advancement in the field of astrophysics leverages very-long-baseline interferometry to link multiple radio dishes ...
Hace 5 días · These computer-simulated images show the emission near the event horizon of a black hole resembling Sgr A* at observing wavelength of 1.3 mm (left) and 0.87 mm (right).
Hace 4 días · Event Horizon Telescope's newest advancements are 'a stepping stone to full color, high-definition movies of black holes.'. This composite simulated image shows how M87* is seen by the Event ...
