WDC is witnessing strong demand. At the same time, its valuation remains attractive relative to its earnings growth ...

These 3D renderings of a direct-horizon collapsar with an initially weak magnetic field illustrate the system’s evolution. Early in the collapse, accretion disk winds unbind much of the stellar ...

Scientists, using the Very Large Telescope, have captured the earliest stages of a supernova explosion, revealing a star 15 times the mass of our sun exploding in an olive-like shape. The study ...
