they use a special thermometer to help them test and evaluate how hot the temperature of the sun is and came up with 27 million degrees (F) atthe core.
touch it and find out...
by knowing the placement of the sun ,earth and the moon
Scientists use instruments like telescopes and spectrographs to study the light and heat emitted by the Sun. By observing the type and amount of energy the Sun gives off, they can estimate its temperature, which is around 5,500 degrees Celsius (9,932 degrees Fahrenheit) at the surface.
Theoretically, scientist do not know what the sun looks like through this perspective. The only way to know is to actually be there. However, research using inductive and deductive empirical reasoning to make accurate assumptions.
Scientists know what the sun is made of by studying its spectrum. By analyzing the light emitted by the sun, they can identify the different elements present in its atmosphere based on the unique patterns of absorption and emission lines. This approach allows scientists to determine that the sun is mainly composed of hydrogen and helium, with trace amounts of other elements.
The sun is made of hot gases
just incase if it goes out
You never know how long is sun going to live because the sun is extremely hot so the scientists cant look inside the core to find out how long did it live, when it was created, and how much longer is going to live.
touch it and find out...
Scientists have not been able to observe the sun close enough in order to discover if their is life on the sun. It has reached temperatures that are to hot for human contact.
The gasses in the sun are very hot and therefore glow; the specific wavelengths of light that they emit are characteristic of specific elements.
by knowing the placement of the sun ,earth and the moon
While it is difficult to know exactly what is going on inside the sun, scientists make educated guesses. They have radio and optical telescopes and other instruments monitoring the sun all the time.
they can use infra red glasses to look at the sun directly Question: but how do they know that there is a core in the sun. the infra red glasses cant just look straight through the sun??!
By the way earthquake waves refract as they pass through it.
Scientists have not found the diameter of the sun and they probably never will because the sun is to hot to get close to so they can't make a measure for it.
Scientists know how the Earth orbits the Sun through observations, calculations, and experiments. The laws of physics, particularly gravity, help explain and predict the Earth's movement around the Sun. By studying the positions of celestial bodies and analyzing data, scientists have determined the Earth's elliptical orbit and its yearly journey around the Sun.
