just incase if it goes out
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??!
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.
I don't know. Ask someone else.
I have never heard that scientists think the sun will explode. I do know they predict that our sun will eventually burn out. But its so far away, it takes billions of years for the dark to reach Earth. So I'm not too worried about the sun blowing up or burning out.
Scientists did not find the sun. The sun has been visible to mankind since the dawn of time.
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.
A million? The age is over 4 billion years.
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.
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.
Our Sun is the center of our Solar System. Without it, life as we currently know it could not exist on our planet. Photosynthesis relies the Sun. Scientists identify our sun a big ball of gas or gasses.
