Astronomers use special filters to observe the sun because the sun emits high-intensity light that can damage the eyes and sensitive equipment. These filters help to reduce the brightness of the sun and allow astronomers to safely study its features, such as sunspots and solar flares.
Astronomers know the temperature of the Sun's corona is high because they can observe the emission of extreme ultraviolet and X-ray radiation from the corona, which is only possible if the temperature exceeds millions of degrees Celsius. These observations are made using instruments such as spectrometers and telescopes designed for detecting these high-energy wavelengths.
The sun is not a solid object and different parts of it rotate at different speeds.
Unlike Earth and other solid objects, the entire Sun doesn't rotate at the same rate of gas and plasma, different parts of the Sun spin at different rates.
No.
Astronomers will always have to observe the sun from a distance. The sun is too hot for anyone to go onto it.
Astronomers use instruments such as spectrometers to analyze starlight and determine a star's chemical composition, temperature, and motion. Telescopes are used to observe stars and capture images at different wavelengths. Interferometers combine signals from multiple telescopes to create high-resolution images of stars and star systems.

Sunspots rotate at different speeds.
Astronomers study the sun, moon, and stars. They observe and analyze celestial objects in order to learn more about their properties, behavior, and evolution. Astronomy is a branch of science that focuses on the study of objects and phenomena in outer space.
Astronomers have inferred that the Sun rotates by observing the motion of sunspots across its surface. This phenomenon, known as differential rotation, causes different parts of the Sun to move at different speeds, indicating that the Sun rotates. Additionally, observations of the Doppler shifts in the light emitted by different regions of the Sun also provide evidence of its rotation.

Astronomers think the sun will die in 2012

Parallax is the method that astronomers use to measure the distance from the sun to the earth.
some of the light from the corona produces a continuous spectrum that lacks absorption lines. however the type is absorption spectrum
