artiteacher Supernovas and cosmic leftovers
Dust of stars, dust of stars! We are glowing with the dust of dying stars.
artiteacher Ancient astronomers worldwide documented brilliant new stars in the night sky, which we now know were supernovas.
artiteacher A supernova is a colossal explosion that rips a massive star apart, scattering heavy elements into deep space.
artiteacher Tug against gravity's relentless pull to discover how stars are born and die.
We are stardust: Nearly every heavy atom in your body, like the iron in your blood, was made inside a dying star.
A star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass. In 1604, Johannes Kepler observed the last supernova visible to the naked eye in our galaxy.
Which heavy elements are forged and scattered into space primarily during a supernova explosion?
What celestial object is formed when a dying star's core is so massive that gravity collapses it completely?
What is a rapidly spinning neutron star that emits beams of radiation like a lighthouse called?
What is the boundary around a black hole from which nothing, not even light, can escape?
In what year did Chinese and Islamic astronomers record the brilliant 'guest star' that created the Crab Nebula?
