The compressed part of the nebula gets smaller and heats up. It eventually become protostar. ]]> 2019-01-10 19:58:23 UTC https://padlet.com/180157/mshxjc6m5woq/wish/319451092 180157 https://padlet.com/180157/mshxjc6m5woq/wish/319848484 The Star becomes more dense. Hydrogen and Helium stay in the atmosphere. Nuclear reactions start to occur.]]> 2019-01-11 19:47:10 UTC https://padlet.com/180157/mshxjc6m5woq/wish/319848484 180157 https://padlet.com/180157/mshxjc6m5woq/wish/319959775 Red Supergiant star. Stars are composed of about 75% Hydrogen and 25% helium.
At this time, Betelgeuse is in the late stage of it's evolution. It is the 9th brightest star in the sky. It is estimated that it will explode as a supernova in about 430 light years.
The layers of a star:
Core: Nuclear fusion occurs.
Radiative zone: Energy from the core moves outward to electromagnetic radiation.
Convection zone: Outermost layer of the sun's interior
Photosphere: Light is radiated.
Cromosphere: Hydrogen admits light which creates a red color.

For example, the Nebula is the early stage of the sun's development. That relates to a fetus, in being the early stage of a human's development. The protostar is most like an infant or a toddler. The main sequence star relates to the stage we are all in today. Eventually humans die, and stars will too.]]> 2019-01-14 21:55:44 UTC https://padlet.com/180157/mshxjc6m5woq/wish/320554350 180157 https://padlet.com/180157/mshxjc6m5woq/wish/322298457 The early stage of a stars development.
