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.
Scientists determine the composition of the Sun's atmosphere primarily through spectroscopy. By analyzing the light emitted by the Sun, they can identify specific wavelengths that correspond to different elements and compounds. When sunlight passes through the Sun's atmosphere, certain wavelengths are absorbed by elements like hydrogen, helium, and heavier elements, creating absorption lines in the spectrum. Comparing these lines to known spectra of elements allows scientists to infer the Sun's atmospheric makeup.
by knowing the placement of the sun ,earth and the moon
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 study the light emitted by the Sun using spectroscopy, which separates sunlight into different wavelengths. By analyzing the distribution of these wavelengths, scientists can determine the temperature of the Sun's surface, which is about 5,500 degrees Celsius. They also use theoretical models and observations of the Sun's behavior to estimate its internal temperature, which is much higher, reaching millions of degrees Celsius.
i dont know
just incase if it goes out
The sun is made of hot gases
Scientists estimate that the sun formed around 4 billion years ago.
they are made of helium and hydrogen scientists know this becuz of a spectrometer

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 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.
