Chandra - along with ESO's Very Large Telescope Array - spied a bright, variable supernova blast located in a galaxy 12 million light-years away. This image is a composite showing the central region of the galaxy in question, which is typically referred to as the Circinus galaxy. In the lower right hand […]

I will make a pedagogical point regarding the visual representation of spacetime singularities (Black Holes). In popularized science articles and books the Black Holes are sometimes represented as …

Beautiful image of a Black Hole 🕳️

Unless you can make a force that travels faster than the speed of light, a singularity is inevitable.

This movie shows a complete revolution around a simulated black hole and its accretion disk following a path that is perpendicular to the disk. The black hole’s extreme gravitational field redirects and distorts light coming from different parts of the disk, but exactly what we see depends on our viewing angle. The greatest distortion occurs when viewing the system nearly edgewise. As our viewpoint rotates around the black hole, we see different parts of the fast-moving gas in the accretion…
