When there is a lot of pressure pushing clouds of dust and gas together, a protostar is formed.]]> 2022-11-14 00:08:00 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2381925916 harrietthoroughgood https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2381928371 Protostars are young stars, they contain a core that isn't yet hot enough to begin nuclear fusion.
Once it has gathered enough mass from its parent molecular cloud, and it's gained enough temperature and pressure, nuclear fusion happens. Then it becomes a main sequence star.]]> 2022-11-14 00:11:20 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2381928371 harrietthoroughgood https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2381933669 Once a protostar has become a main sequence star, there are two paths it can take:
Path A) Which is a high mass star. They contain more fuel and are a higher temperature.
Path B) These are average or low mass stars. They have less fuel and have a cooler temperature.]]> 2022-11-14 00:16:56 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2381933669 harrietthoroughgood https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2381934183 Average or low mass star

When the fuel begins to run out, the core will shrink and its temperature will rise, making the excess energy radiate outwards, pushing the outside layers away from the core - this will form a red giant]]> 2022-11-14 00:23:33 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2381940930 harrietthoroughgood https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2381943612 When all the hydrogen goes, nuclear fusion will change, fusing helium together to make heavier elements.

Gravity forces the outer layers towards the core, causing it to bounce off and create an explosion known as a supernova. ]]> 2022-11-14 03:34:20 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2382174784 harrietthoroughgood https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2382175068 Once a supernova is created there are two different paths it can take:
It can compress into a giant ball of neutrons called a neutron star.
Or a gigantic star that undergoes supernova can make a black hole. ]]> 2022-11-14 03:34:36 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2382175068 harrietthoroughgood https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2382175395 A neutron star is the compressed giant ball of neutrons that were left over from the supernova.]]> 2022-11-14 03:34:53 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2382175395 harrietthoroughgood https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2382175789 Black holes are so dense that even light can't escape its gravity.

They're formed because of the pressure of gravity causing the core to be packed densely with 0 volume.]]> 2022-11-14 03:35:10 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2382175789 harrietthoroughgood https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2383906376 It is believed that when a White Dwarf cools down it looses its glow and becomes a Black Dwarf]]> 2022-11-15 01:33:59 UTC https://padlet.com/harrietthoroughgood/3i88hj4mdhhch92i/wish/2383906376
