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 20:07:40 UTC https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345832924 belletiereb https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345833116 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 20:07:51 UTC https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345833116 belletiereb https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345837244 Stars that have at least 3 times the mass of the Sun and up. The more massive a star, more nuclear fusion is occluding and the more energy it gives out. Blue light is emitted as more energy on the light spectrum is produced.

Real Life Example: Rigel is the brightest star in the constellation Orion and the 6th brightest star in the sky.

Real Life Example: Betelgeuse is the most popular Red Giant that we can see, located in the constellation of Orion.]]> 2022-10-18 20:13:10 UTC https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345838802 belletiereb https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345839011 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 20:13:23 UTC https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345839011 belletiereb https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345842434 Stars at high density have neutrons that are brought into contact, causing a rebound effect and explodes into a powerful shock wave.  

Real Life Example: Chinese astronomers in 1054 observed the formation of the Crab Nebula. ]]> 2022-10-18 20:16:26 UTC https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345842434 belletiereb https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345845890 Formed by the gravitational collapse after a Supernova explosion due to tightly packed neutrons in a very small radius. A star in this stage can become a black hole, the last stage of its life. 

Real Life Example: The Black Widow Pulsar is the first neutron star discovered with planets. ]]> 2022-10-18 20:19:30 UTC https://padlet.com/belletiereb/jme7brev009fl5li/wish/2345845890
