Galileo and the German Jesuit Christoph Scheiner each saw them in 1611, and vied bitterly in their lifetimes over who deserved the credit for discovering them. One Of These Sucked In A Comet That Flew Too Close, The structure of sunspots are granule, penumbra, and umbra. The outer, paler part is called the penumbra. The inner cooler part of a sunspot is called umbra. These spots can spread to be 50,000 miles in diameter. These occur only once every eleven years. These occur due to magnetic activity that reduces the surface temperatures. Sunspots are small dark patches, or black areas, or dark areas on the surface of the Sun, whiched marked strong pockets of magnesium. These can last for weeks and can cause coronal mass ejections. They are then referred to solar filaments. Sometimes, these prominences can form in front of the Sun.
No one is sure exactly how these prominences are formed, yet these can extend for thousands of miles across the surface of the Sun. Solar wind is one cause of the extent due to the escape velocity of the Sun being 55 times the Earth's.Ī prominence is an outburst of plasma from the photosphere, extending into the upper corona. Solar flares can reach extend one hundred thousand miles from the surface of the Sun. Solar flares release an abundance of radiation to the Earth, sometimes knocking out powerlines and causing power outages.
Solar flares are outburst of flames from solar wind, which can reach speeds one million kilometers per second.

Then, a series of 32 explosions occurred, that passing comet was sucked into the sunspot. Then these particles make a cloud called the coma.Ī comet called Skara-0A99 smashed into the Sun in 2014, it burned and broke into 55 pieces. When a comet gets close to the Sun, the ice will start to melt with particles and dust. The sun’s core will will run out of fuel and the sun will explode into a Stellar Blackhole. It will stay like this until the final stage of the universe, proton decay. The Sun will transform into an iron star when the only stable elements in the universe is iron. This will unstabilize the orbits of all the planets in the Solar System and most likely eject the Kuiper belt and the Ice Giants. It will stay as a white dwarf for around a trillion years, until its final energy source has disappeared, leaving the Sun as a black dwarf. The final remains of the Sun will be its former core, a white dwarf, which is the size of Earth's diameter but being half of the Sun's normal density. Once enough mass is gone, the Sun will start shrinking and eventually detach all of its atmosphere, leaving them as a planetary nebula that would stretch into the interstellar bubble. After engulfing Hephaestus's orbit, the Sun will start experiencing thermal pulsations and cause massive coronal mass ejections, blowing off 25% of the Jupiter's mass into outer space and possibly vaporizing Mars's outer crust. In around 7.8 billion years, the Sun will enter a red giant phase and engulf Hermes, Cybel, and Hephaestus's orbit and vaporize the entire three planets. In around 5 billion years, the Sun's core will get exhausted of hydrogen and enter a subgiant phase, where the Sun enlarges its size of about 3 ~ 10 times its current diameter. The Sun firstly formed as a Brown Dwarf and then later a T-Tauri Star, then entered Main Sequence as it gained enough mass for fusing hydrogen into helium. The Sun formed from at the center of the rotating disk of materials that was once known as the Solar Nebula. Though the corona is the main atmosphere, before it is what is known as the transition region, the point at which the temperature transitions from the hotter parts of the photosphere, which is 36,000 degrees Fahrenheit, to the corona, reaching 1.8 million degrees Fahrenheit. The corona is one trillion times less dense than the photosphere, yet it can reach three million degrees Celsius. The corona can only be seen during an eclipse. The Sun's atmosphere is called the corona. This keeps the Sun in a stable state and position, but will not last long. The reason the Sun emits so much heat is because of the nuclear fusion power that fuses hydrogen into helium in its core, allowing it to release extra energy and emit serious amounts of light and heat.
The Sun's surface burns at a temperature of 5504 degrees Celsius and its core boils at a temperature of 15 million degrees Celsius. Because of its massive gravity, it is able to keep all the objects in the Solar System in a stable orbit. It is 1.989 × 10^30 kg in mass, or a million times more dense than the Earth and a thousand times more dense than Jupiter. It is 1.3 million km in diameter and is 94 million miles (or 1 astronomical unit) to Earth in distance. The Sun is an average sized G-type Main Sequence Star, or a Yellow Dwarf, located at the center of the Solar System. 94.4 million miles from Earth (1 astronomical unit)īarley-like surface texture with sunspots
