Unsolved problems in astronomy

Unsolved problems in astronomy are questions that astronomers do not know the answers to yet. Astronomers use special telescopes to look at stars, planets, and other objects in space, but there are still many things that they do not know. Some of these unsolved problems include the mystery of dark matter and dark energy, which is something that takes up most of the universe but cannot be seen. Astronomers also do not know how planets and stars form, and why some stars explode. Unsolved problems in astronomy are what makes it such an exciting field for scientists to explore.
