Astrophysicists have observed our central supermassive black hole. They found the accretion disk is constantly emitting flares without periods of rest. Shorter, faint flares and longer ...

Called an accretion disk, this ring of matter around Sagittarius A* spewed everything from brief flickers that only last a few seconds to incredibly bright daily eruptions to even faint flickers ...

Uncover the Webb Telescope's fascinating discovery of a 34-million-year-old planet-forming disk around a red star.

In an attempt to tackle these questions, a research team simulated the action of a so-called accretion disk around a supermassive black hole; not only could this simulation grant crucial insights ...

Its supermassive black hole, dubbed Sagittarius A*, is surrounded by a swirling mass of gas and dust called an accretion disc. Sagittarius A* is just 26,000 light-years from Earth — relatively ...

It can lead to pain, numbness, and weakness in your back, legs, and arms. Often you can relieve a herniated disk with rest, pain relievers, and physical therapy. But if your symptoms don't get ...

External USB/Thunderbolt drives (aka direct-attached storage, or DAS) are a super-convenient way to quickly back up your important files, as well as store any data that you don’t need on your ...

Laptop drive almost full? Need to back up your photos? Desktop-size and portable platter storage has never been cheaper. Our deep-dive reviews help you track down the right external hard drive ...

By peering deep into the heart of our galaxy, Webb has captured a continuous sequence of flares erupting from the black hole’s surrounding accretion disk. These flashes come in varying intensities, ...
