Scientists do have a pretty good idea of what a lot of "space stuff" is made of, giving them better ideas about what it might smell like. Memorably, the dust cloud at the center of the Milky Way contains large amounts of ethyl formate. This is the compound that, on Earth, gives raspberries their flavor. Yes, raspberries.
Our solar system has eight planets, and five dwarf planets - all located in an outer spiral arm of the Milky Way galaxy called the Orion Arm. National Aeronautics and Space Administration. NASA explores the unknown in air and space,
Astronomers estimate that the universe could contain up to one septillion stars – that''s a one followed by 24 zeros. Our Milky Way alone contains more than 100 billion, including our most well-studied star, the Sun. Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. []
