The Hubble Space Telescope is a telescope that orbits Earth from 593 km above sea level, allowing it to observe space without interference from the atmosphere. One key feature is that astronauts could visit it for service missions. The document also describes a photo of the Veil Nebula, which was formed around 8,000 years ago by the supernova explosion of a massive star 20 times the size of our sun.
