Zeta Ophiuchi has had an interesting life. It began as a typical large star about twenty times more massive than the sun. It spent its days happily orbiting a large companion star until its companion exploded as a supernova ...

(Phys.org)—Physicists have discovered a surprising consequence of a widely supported model of the early universe: according to the model, tiny cosmological perturbations produced shocks in the radiation fluid just a fraction ...
When a star explodes as a supernova, it shines brightly for a few weeks or months before fading away. Yet the material blasted outward from the explosion still glows hundreds or thousands of years later, forming a picturesque ...
