Gravity must be stronger than the pressure to form stars.

Real Life Example: The Orion Nebula can be seen with the naked eye, located in the sword of Orion’s constellation. ]]> 2022-10-18 15:54:50 UTC https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345410103 belletiereb https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345418224 Formed by gravitational accretion of dust and gas. Microwave radiation sweep away gases and can cause interstellar dust to glow as the pressure and temperature rise.

Real Life Example: NASA discovered a star forming in the protostar stage as it is large and bright red, 12,000 light years away from earth.]]> 2022-10-18 15:58:55 UTC https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345418224 belletiereb https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345425138 90% of a stars lifetime, in this stage stars fuse hydrogen atoms into helium atoms in their cores.

Real Life Example: Our sun.]]> 2022-10-18 16:02:20 UTC https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345425138 belletiereb https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345431056 The helium core contracts as the core is depleted of hydrogen. No hydrogen remains in the core to fuel nuclear fusion.

Real Life Example: Betelgeuse is the most popular Red Giant that we can see, located in the constellation of Orion.]]> 2022-10-18 16:05:23 UTC https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345431056 belletiereb https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345443536 The largest stars in the universe in terms of volume. In this stage, hydrogen is completely gone as it undergoes nuclear fusion in the outer shells. The shells expand, creating a red color and cooling off the largest stars to exist. 

Real Life Example: Antares is a well known Red Supergiant, located in the heart of Scorpius the Scorpion. ]]> 2022-10-18 16:11:46 UTC https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345443536 belletiereb https://padlet.com/belletiereb/6a8nxang8psfegok/wish/2345820173 As the star is dying, the outer layers cast off cosmic gas and dust. This stage is too small for Carbon fusion. 

Real Life Example: Our sun is expected to form a planetary nebula by the end of its life. The Helix Nebula is a trillion mile long tunnel of glowing gases and holds a White Dwarf in the center.

It’s located int he center of a Planetary Nebula and is held by electron degeneracy pressure. 

Real Life Example: Our sun is also predicted to become a White Dwarf just like Sirius B which is the closest White Dwarf Star to us at a distance of 8.6 light years away.
