"Breathtaking" images of a stellar nursery in the Orion Nebula taken by the James Webb Space Telescope are revealing intricate details about how stars and planetary systems form. The images, released ...

At just 25, Cecilia Payne-Gaposchkin applied quantum physics to a treasure trove of astronomical observations to show that stars are mostly hydrogen and helium.

Pictures are the key to new insights in the field of astrophysics. Such images include simulations of cosmic events, which astrophysicists at UZH use to investigate how stars, planets and galaxies ...
