🌟Elements in the universe are made up of protons, neutrons, and electrons.
🔬Scientists use different telescopes to analyze the light emitted by objects in space and determine their composition.
🔭Telescopes like the Large Binocular Telescope and the Hubble Space Telescope help in understanding the composition of stars and galaxies.
🌌Elements like hydrogen and helium make up the majority of our universe.
🔍The periodic table of elements contains all the elements that exist in the universe.
How do astronomers determine the composition of objects in space?
—Astronomers analyze the light emitted by objects and break it down into its component colors to identify the elements present.
Why is the periodic table of elements important?
—The periodic table contains all the elements that exist in the universe, allowing us to understand the building blocks of matter.
Which elements are most common in the universe?
