Master of How stars are born and die
artiteacher The stellar nurseries
Deep in the dust where the pillars rise, A million baby stars ignite the skies.
artiteacher Nuclear fusion ignites when a protostar's core becomes hot and dense enough to fuse hydrogen into helium.
artiteacher Gravity acts as a cosmic architect, pulling gas and dust into dense, spinning pockets that eventually form protostars.
artiteacher Swipe swirling cosmic dust together to learn how stars are born and die.
Stellar baby boom: The Milky Way galaxy produces about seven new stars every single year.
A diffuse cloud of interstellar dust and gas in outer space. In 1995, the Hubble Space Telescope photographed star birth within the Eagle Nebula's Pillars of Creation.
What force is primarily responsible for pulling cosmic dust and gas together to form a protostar?
What is the name of the famous stellar nursery located 6,500 light-years away containing the 'Pillars of Creation'?
At what temperature does the core of a protostar typically begin nuclear fusion to become a real star?
In what year did Swiss astronomer Jean-Philippe de Cheseaux discover the Eagle Nebula?
What is the primary element that makes up giant molecular clouds where stars are born?
