Why is it important to study space?
Space exploration allows us to prove or disprove scientific theories developed on Earth . Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets.
How do astronomers learn about stars?
The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy . Today, this process uses instruments with a grating that spreads out the light from an object by wavelength. This spread-out light is called a spectrum.
Can you see stars in space?
The stars aren’t visible because they are too faint . The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures. With those camera settings, though, the stars don’t show up.
How many types of astronomy are there?
Modern astronomers tend to fall into two fields : the theoretical and the observational. Observational astronomers focus on direct study of stars, planets, galaxies, and so forth. Theoretical astronomers model and analyze how systems may have evolved.
