SpaceX has more than 3,700 Starlink satellites in orbit, providing broadband internet access to subscribers around the globe. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earths atmosphere. Telescopes are placed into orbit around the Earth or are sent farther out into space to get a clearer view of the Universe.
