Black holes, regions in spacetime where gravity is so strong that nothing can escape from them, are among the most fascinating and widely studied cosmic phenomena. While there are now countless theories about their formation ...
(PhysOrg.com) -- As computer chips become more powerful, they also become hotter. Nearly all the power that flows into a chip comes out of it as waste heat, and that heat hurts the performance of the chip.
Using NASA's Transiting Exoplanet Survey Satellite (TESS), Chinese astronomers have detected quasi-periodic oscillations (QPOs) in the light curve of HS 2325+8205—a long-period eclipsing dwarf nova. The discovery was detailed ...
For the first time, NASA's Neutron star Interior Composition Explorer (NICER) has observed the merging of multimillion-degree X-ray spots on the surface of a magnetar, a supermagnetized stellar core no larger than a city.

Using European Southern Observatory's Very Large Telescope (VLT), astronomers have investigated the galaxy NGC 1365. The study, presented in a paper published January 18 on the arXiv.org pre-print server, reveals essential ...
Scientists analyzing the first data from the Neutron star Interior Composition Explorer (NICER) mission have found two stars that revolve around each other every 38 minutes—about the time it takes to stream a TV drama. ...
