Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

A hidden world of blue and black holes pockmarks the coastline and interior. Andros has 200 blue holes, the highest concentration in the world. Blue holes typically occur around limestone.

It's like a black hole but on earth. Scientists have identified what could potentially be the "deepest known blue hole" in the world -- which extends so far down that the bottom has not yet been ...

OK, so the no-hair theorem tells us that black holes can exhibit any of the charges of the fundamental forces, so we should be able to have a red or an anti-blue black hole, from a quantum ...

A new generation of black hole research is unfolding thanks to artificial intelligence, massive simulations, and cutting-edge ...

The first object is a very hot, blue star with 25 times the mass of the Sun, and the second is a black hole nine times more massive than the Sun. VFTS 243 is located in the Tarantula Nebula within ...

AIR AND SPACE Supermassive black hole devours a star, blasts its remains at Earth The jetted beam was initially red in color before it decayed over four days and changed to a blue hue ...

The black hole, dubbed J221951, is estimated to sit about 10 billion light-years from Earth, ... But unlike a kilonova, which first appears blue before dimming to red over several days, ...

This composite simulated image shows how M87* is seen by the Event Horizon Telescope at 86 GHz (red), 230 GHz (green), and 345 GHz (blue). The higher the frequency, the sharper the image becomes ...

Black holes are "dormant" if they do not emit high levels of X-ray radiation, which is how they are typically detected. Identification of VFTS 243 was made thanks to six years of data obtained ...

A black hole is a region of spacetime where gravity is so intense that nothing, no matter how much energy it has, can escape.Inside the event horizon, gravity supersedes all other forces of nature.
