Hey yo peeps! So were going to learn abbout the life cycle of stars! Amazing right!  Sorry so happy to teach you about this.  First were going to talk about steller nurseries. What are stellar nurseries you ask. A stellar nurseier is were baby stars are born. Awwww cut-
e star look over there!

 Lets talk about prostars!  A prostar is like a baby star. Acually it is excactly a baby star. One day it will go into the main- sequence of its life! Not so cute then. Stellar nurseries are were prostars are born. You already read about that in the first paragraph. Well lets move on.

Were going to talk about nuclear fusion right now! The fusion in the star's atoms create hydrogien. Nuclear fusion also genrates a lot pf energy causing the star to ingnite.  Just like use except we don't go into flames or exploded...  anyway.  Every star has to ignite at some point. Lets move on people.

  

 

Lets talk about the main-sequence stage in the stars life. In the stars main sequence witch is the longest part of the stars life a few things happen. 1) the star starts to lose fuel and 2) then it will turn into a red giant and many more things! Well lets move on. 

 

 

 

         this is what happens after its main sequence.  It dependeds on the stars mass after the main sequence. 1) If it is very very low in mass its main sequence may last a trillion years longer that our universe.  2) If its a mid size star like our sun it will expand into a red giant and swallow us up!!!! 3) If its larger than our sun then it will collapes into a nutron star or a black hole! Anyway lets move on .

After all that scary stuff with all the red giant and stuff it becomes a white dwarf.  After like trillions of years it finally cools down into a white dwarf. A white dwarf is the end of the stars life. So sad. Well not much to a white dwarf really. Well lets move on.

Were going to talk about a plantery nebula. A plantery nebula is made out of gas and dust. It relates to its life cycle of stars because thats how a star stars out. the life cycle is ... plantery nebula, prostar, main sequence, red giant, white dwarf,and more. Lets talk about some thing eles.

Well in a supernova a star has to be larger than our sun. A supernova is a star that collapes on itself and explodes!!!!!!!!!!!!! Ahhhhhh scary!

What is a netron star you ask? Well a nutron star is a very high density star that is packed with nutrons.  They are made by big stars collapeing after a supernova and it spins!!!

What is a pulsar???? Well... it is a spinning nutron star that gives out radio waves. Well not much there. Shall we?

After a supernova what happens? Well after a supernova it can become a nutron star or a black hole. A sigularty is formed to make a black hole. A black hole is a hole that is black and is invisible and nothing can escape it not even light. Well peace out :D :D :D :D

 

 

 

 

 

 

 

 

 

 

 

BlackHoles

 

 

 

 

Hello! We are going to talk about black holes! Scary AHHHHHH! Ok anyway... So what are blackholes you ask. Weellll a blackhole is invisable holes that suck things into it. There are two places in a black hole, Event Horizon and No Return! SCARY!!!

 

Blackhole sucking in star

 

 

 

What makes a blackhole you ask. Well things. Fine I'll tell you. A blackhole can be made two diffrent ways. 1) the fuel eventually runs out and it implodes. 2) A collection of matter at the center of a galaxy and it callapes on itself! AHHHHHH!!!!!

 

 

 



Star exploding

 

 

 

You see an black hole is so strong that even light can't escape it! Thats why its called a black hole. What? You don't know what I mean! There's no light in a black hole so its dark.  BOOOOM! Hey its a star exploding!!!  AHHHH run for your life! Just kiding.

Black holes may be small but thier powerful... Some black holes in the center of galaxys are about Two million miles across! Wow thats a lot Sciencecat!  Some people like to think as them as Worm holes! Why Meap? Welll its a hole and... I don't want to explain this!

There are two kinds of blackholes. 1) Schwarzschild- a non rotating black hole and 2)Kerr- a rotating black hole. A Schwarzchild  is very simple it only has an event horizen and a singularity. A Kerr on the otheer hand is less simple it rotates, has a event horizen and a singularity!PEACE OUT!!!!

Our Milky Way

The Milky Way is a galaxy That we live in. Were just a tiny tiny spec of  the Milky Way. From the
 Earth the galaxy looks milky and hazy. That is why we call it the Milky Way.  

                                                                                                                                      Black hole

Some astronomers think there is a Supermassive Blackhole in the middle of the galaxy! A black hole is when two or a group of stars clasp and turn into a blackhole!  You may think a black hole is cool like my friend over there but its not! Not even light can escape the pull of the black hole! Thats bad.  There are other things lets get away from the black holes or else it will suck us in.  The earth is located on the Orion arm.  Our solar system orbits or goes around the galactic center.  The Milky Way is made up of planets,gas, dust, and a unknown substance called dark matter. What is a Halo. You may think that it is a hat that angels wear thats one thing but a Halo is outside of a disk is the Halo.  Our Solar system is only a little spec of our galaxy! We look that small! Yes Emma we do look that small.  We are 26,000 light years away from the center! Thats a lot!
