As you probably saw through playing around with weights on other planets, weight in deep space is always zero and mass for a given person is always the same, but weight can change on other planets. This is because other planets have different amounts of gravity. Gravity is that invisible, powerful force I was talking about earlier. It's a force of an attraction, making everything in the universe 'pull' each other together. However, that pull is very weal for most things, so weak we can't feel or even notice it. For really massive things, like planets, it is definetly noticible, because the more mass something has, the more it 'pulls' other things towards it. Gravity is what pulls us towards the Earth and prevents us from flying away, or jumping as high as we want. Because other planets have more or less mass, they have a stronger or weaker gravity, and 'pull' things more or less. So, on Mercury, which has not a lot of mass, the 'pull' isn't very strong. But on Jupiter, which does have a lot of mass, it is very strong.")

Elements are the building blocks of the universe, comprising all of the things in the universe. When these elements are spread really thin, they can let light go through them, and 'split' it, making a rainbow. A rainbow is a type of spectrum. All a spectrum is is a collection of lights. When things get really hot, thousands of times hotter than a summer day, things start to glow, and light up. The sprectra shown are a sort of rainbow that you can see by looking at really hot versions of the elements through a prism, which is a triangular wedge of glass. Stars are me up of really hot elements, and by looking at them through a telescope and a prism, astronomers can see the 'rainbows' made by the elements in the star, and figure out what they're made of, which is pretty neat. Do you know another way of figuring out what things too far away to imagine are made of? I don't. Let's have some fun matching the known element's spectra, on the left, with the mystery ones on the right.")
