Stars form in regions of space known as stellar nurseries, where high concentrations of gas and dust coalesce to form a baby star. Also called molecular clouds, these regions of space can be massive, ...

An international team led by the University of Geneva (UNIGE) has identified three ultra-massive galaxies—nearly as massive as the Milky Way—already in place within the first billion years after the ...

Look at this new radio image covered with dots, each of which is a distant galaxy! The brightest spots are galaxies that are powered by supermassive black holes and shine bright in radio light. But ...
