Space weather explorers week

The Sun is over a million times bigger than the Earth! But it is so far from our planet that it looks small in the sky. Even at that great distance, the Sun influences us in myriad ways. Space Weather Explorers Week is a collection of lessons and activities about the Sun-Earth connection. Several times each year you can interact live with NASA scientists and ask them your questions. Our next 2024 live week will be announced here — check back soon!

The story of Carruthers Geocorona Observatory

The outermost layer of Earth’s atmosphere is called its exosphere, or sometimes the geocorona. So far, there have only ever been four images taken of the exosphere. The first image was from a telescope placed on the Moon during the Apollo 16 mission in 1972. The telescope was built by Dr. George Carruthers to observe Earth in ultraviolet light. As part of NASA’s efforts to better understand the Earth, its space environment and its interactions with the Sun, a new mission is under development. Set for launch into space in 2025, the Carruthers Geocorona Observatory will study Earth’s exosphere and how it changes over time.
