Exploring eruptions from the Sun

In our solar system, solar flares and coronal mass ejections (CME) are the most spectacular eruptive activities. Large solar flares and CMEs may bring us disastrous space weather, destroy our satellite and navigation system, ...

How bad can solar storms get?

Our sun regularly pelts the Earth with all kinds of radiation and charged particles. How bad can these solar storms get?

Solar fleet peers into coronal cavities

(Phys.org)—The sun's atmosphere dances. Giant columns of solar material – made of gas so hot that many of the electrons have been scorched off the atoms, turning it into a form of magnetized matter we call plasma – ...
