The Sun
The sun is a ball of hydrogen gas. 1,000,000 Earths can fit inside the sun.
an eruption of energy was unleashed in 2003. this eruption was equal to 200 billion hydrogen bombs. when this occurred, astronauts had to hide in the most safest compartment, the power went out, and there was no communication.
The hottest temperature ever recorded on Earth was 134 degrees Farenheit in Death Valley, Cali.
The sun is a star which is a ball of gas. The sun is a middle aged star of average size
The sun has a lot of layers. From the inside which is the core to the most outer layer which is the corona.
The core is the center and it produces the light and heat. It fuses atoms of hydrogen to produce helium. It is about 28,000 degrees Farenheit.

The radiative zone extends 70% out of the core. Energy produced in the core extends out into the zone.
The enegry that is from the radiative zone transforms into gases in convection cycles to go into the convective zone
The photosphere is a thin layer and can be seen yellow in Earth. You can see it with the right telescope. You can also see small dots called granules and sunspots. Sunspots are caused by magnetic activity in the convection zone
The coolest layer is the chromosphere.
The outermost layer is the corona. This a thin and wispy layer. It is also very hot. Particles of this layer can escape and blow towards Earth and it is known as solar wind.
The loops that extend off of the surface of the sun are called prominences.
Since the hydrogen atoms are so hot and under so much pressure, they fuse together .
To know how much energy is in the sun, imagine the weight of 15 empire state buildings. That's how much energy is being converted in the sun.
The only time you can see the corona is during a solar eclipse
the magnetic fields on the sun can get tangled up. if they cool down, they can turn into a sunspot.
the fiery arches that are on the sun are known as prominences. if the conditions are right, they can snap and cause a solar flare. It releases 10% of the energy.
NASA launches highbacks to study the effects the sun has on the farthest reaches of our solar system
Deep in the sagittarius constellation, there are to stars that are locked together in this spinning rotation. This rotation happens every eight months.
One of the stars in that rotation will burst causing a supernova. Not only will they cause a supernova but they will be emitting gamma ray burst
millions of years ago, a gamma ray burst occurred. At the time there was only sea life. The sea life that was at the bottom weren't affected but life near the surface or on the surface were severely affected.
The heliosphere is the bubble that protects the solar system and the sun from intergalactic winds
Over the years, this bubble has gotten smaller and weaker. If it continues it can harm the solar system and earth. Even though earth has two shields which are the atmosphere and the magnetic field, it is still danger.
