Sunspots are caused by complicated and not very well understood interactions with the Sun’s magnetic field.The Sun is about 4.5 billion years old. Each second about 700,000,000 tons of hydrogen are converted to about 695,000,000 tons of helium and 5,000,000 tons (=3.86e33 ergs) of energy in the form of gamma rays. Sunspots can be very large, as much as 50,000 km in diameter.
Partial eclipses are visible over a wide area of the Earth but the region from which a total eclipse is visible, called the path of totality, is very narrow, just a few kilometers (though it is usually thousands of kilometers long). The differential rotation extends considerably down into the interior of the Sun but the core of the Sun rotates as a solid body.A small region known as the chromosphere lies above the photosphere.The Sun’s output is not entirely constant. A hopeless romantic ambivalent about his future in medical school falls for a hard-luck young woman who doesn't believe in love. It will continue to radiate “peacefully” for another 5 billion years or so (although its luminosity will approximately double in that time).
And you can see the solar corona. That’s true in the sense that there are many others similar to it. The corona generally ranges from 900,000 F (500,000 C) to 10.8 million F (6 million C) and can even reach tens of millions of degrees when a solar flare occurs. The Sun is by far the largest object in the solar system.
It contains more than 99.8% of the total mass of the Solar System (Jupiter contains most of the rest).It just happens that the Moon and the Sun appear the same size in the sky as viewed from the Earth. The stars come out. Pluto is no longer officially a planet but we’ll keep it here for history’s sake.
Solar photons reach Earth about eight minutes after they're freed from the sun's interior, crossing an average of 93 million miles to get hereâa distance defined as one astronomical unit (AU).Out beyond the sun's photosphere lies the atmosphere, which consists of the chromosphere and the solar corona. Network Study says better aircon can slow global warming July 18, 2020. https://www.nationalgeographic.com/science/space/solar-system/the-sun There was a period of very low sunspot activity in the latter half of the 17th century called the Maunder Minimum. But since the path of totality is so small it is very unlikely that it will cross you home. If you stay home, you’re likely to see a partial eclipse several times per decade. Two main kinds of solar convection cells exist — granulation cells about 600 miles (1,000 kilometers) wide and supergranulation cells about 20,000 miles (30,000 km) in diameter. Roiling "convection cells" of gas dominate this zone. Since the formation of the solar system the Sun’s output has increased by about 40%.Our Sun is a normal main-sequence G2 star, one of more than 100 billion stars in our galaxy.The Sun is by far the largest object in the solar system. Its closest approach to the sun will be 26 million miles (43 million km) — about 25 percent closer than Mercury. At the top is the super-hot corona, which is made of structures such as loops and streams of ionized gas. Sun Star has strived to bring to the demanding collector the very best quality die-cast collectible money can buy. They form in areas of strong magnetic activity that inhibit heat transfer.
