(Phys.org)—The Hubble Space Telescope Hubble Tarantula Treasury Project (HTTP) survey has revealed new insights on the star formation history of the oldest star cluster in the Tarantula Nebula (also known as 30 Doradus), ...
When a star with a mass of roughly ten solar masses finishes its life, it explodes as a supernova, leaving behind a neutron star as remnant "ash." Neutron stars have masses of one-to-several suns but they are tiny in diameter, ...
