Solar Flares By william gao and thibault logette

What are solar flares?

Solar flares are short eruptions with high radiation.

All stars (such as our Sun) are created from collapsing clouds of gas and dust called nebulaes.

After millions of years these nebulaes settle and form protostars.

Once nuclear fusion starts gappening, the protostar is going to evolve into a red giant. Our Sun is currently a red giant. For a very, very long time, this red giant will burn hydrogen to live.

Once the planet has run out of hydrogen, it devolves into a white dwarf. As a white dwarf, it is much smaller and dimmer thatn a red giant.

The outer radiation and emissions of the white dwarf is called planetary nebulae.

If the white dwarf collapses, the explosion and its remains are called supernovas.

When a supernova collapses, it can evolve into a black hole, which is a point where gravity is so strong, it even absorbs light!

Fun Fact! If you to go into a black hole and survive, you would be stretched like a spaghetti!

All of these star pictures and explanations are pretty, but it doesn't explain what a solar flare does. Why are solar flares classified as a major natural disasters? This is video explains all!

If a solar flare happened and the radiation came towards Earth, then all technology would cease. That means no wifi, no hot water, no grocery store and no cars! You would stuck, just like in Paper Day!
