Hace 5 días · A team of scientists using Webb was able to discern that GN-z11 has a central black hole with a few pieces of evidence. "We found extremely dense gas that is common in the vicinity of supermassive ...
Hace 4 días · Since space-time is warped around a black hole, so are the images of the sky, the black hole’s disk, and the photon ring. It takes the camera three hours of real-time to fall into the event ...
Hace 4 días · NASA has unveiled a groundbreaking visualisation that allows the public to take a virtual journey near a black hole, combining scientific theory with digital imagery. Developed by astrophysicist Jeremy Schnittman, this tool offers two scenarios: one where a camera approaches the event horizon and is slingshot back out, and another where it crosses the event horizon, illustrating the intense ...
Hace 6 días · In this movie-style poster, the viewer gets the feeling of being on a precipice, teetering just on the edge of a black hole’s event horizon. The event horizon isn’t a solid surface like Earth’s or even the Sun’s. It's the boundary where the black hole's escape velocity equals the speed of light, the speed limit of the universe. Once matter crosses the event horizon, it will never ...
Hace 5 días · Astronomers have discovered black holes ranging from a few times the sun's mass to tens of billions. Now a group of scientists has predicted that NASA's Nancy Grace Roman Space Telescope could ...
