We study the Sun and how it affects space around Earth and other worlds, producing key knowledge to protect astronauts, satellites and robotic missions.
Radiation from the Sun breaks apart molecules in the Martian atmosphere, in turn producing an ultraviolet glow. New research shows this nightglow pulses during certain seasons, helping scientists better understand circulation patterns in Mars’ atmosphere:
The Sun may seem calm and unchanging, but it's a dynamic star, constantly releasing solar material and radiation that affect the entire solar system. Join solar scientists on @NASA’s Curious Universe podcast to explore our lively and mysterious star:
Scientists sometimes use harmless tracing gases released from sounding rockets — seen here — to illuminate the invisible currents in the upper atmosphere. This Jan. 2018 flight revealed turbulence in an otherwise stable layer of the atmosphere:
The curling waves in this image trace out invisible currents in the upper atmosphere, revealed by a sounding rocket flight in Jan. 2018. The study showed turbulence sloshing in an otherwise stable layer of the atmosphere. Read more:
#SolarOrbiter has made its first close pass by the Sun, studying our star and space with a comprehensive suite of instruments — and the data is already revealing previously unseen details. This is #TheSunUpClose .
