What is in space?

What space stars do of?

Basically, stars are big exploding balls that gas, largely hydrogen and helium. Our nearest star, the Sun, is so warm that the large amount that hydrogen is experience a consistent star-wide nuclear reaction, favor in a hydrogen bomb. Even though it is continually exploding in a atom reaction, the Sun and other stars room so big and have actually so much issue in them the it will certainly take billions of years because that the explode to use all the "fuel" in the star. The vast reactions taking place in stars are constantly releasing power (called electromagnetic radiation) right into the universe, i m sorry is why we deserve to see them and also find lock on radio telescopes such together the people in the Deep an are Network (DSN). Stars, including the Sun, likewise send out a solar wind and burst out occasional solar flares.

Scientists think the the core of the sun is a 15 million level Celsius plasma, a soup of electrons and also protons that room stripped native hydrogen atoms. This "soup," called plasma, provides up 90 percent that the Sun. Every second, thousands of protons in the Sun"s core collide with various other protons to develop helium nuclei in a nuclear combination reaction that releases energy. Just external the core, power moves outside by a procedure called radiation. Closer to the surface, the power moves out by a process called convection - warm gases rise, cool, and sink ago down again. Together these masses the gas move, they press off of each other leading to "Sun-quakes." These do the product in the sunlight vibrate. These Sun-quakes aid scientists determine the Sun"s inner structure and the processes arising at various locations underneath the Sun"s surface.

This drawing shows the major features of the Sun. The sun actually consists of 90% hydrogen and a mixture of other gases. In diameter, the is end 100 time bigger than the Earth.

What function does the sunlight play in room missions choose DS1"s? much more about radio waves and electromagnetic radiation will certainly DS1 obtain heated directly by the Sun? Does heat travel in different way in room than it does ~ above Earth?
