Solar Flare and a Coronal Mass Ejection
Solar Flare and a Coronal Mass Ejection

A medium-sized (M2) solar flare and a coronal mass ejection (CME) erupted from the same, large active region of the Sun on July 14, 2017. The flare lasted almost two hours, quite a long duration. The coils arcing over this active region are particles spiraling along magnetic field lines, which were reorganizing themselves after the magnetic field was disrupted by the blast. Images were taken in a wavelength of extreme ultraviolet light.
Solar flares are giant explosions on the Sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). While these are the most common solar events, the Sun can also emit streams of very fast protons � known as solar energetic particle (SEP) events � and disturbances in the solar wind known as corotating interaction regions (CIRs).

Solar Eclipse seen over Ross Lake
Solar Eclipse seen over Ross Lake

This composite image shows the progression of a partial solar eclipse over Ross Lake, in Northern Cascades National Park, Washington on Monday, August 21, 2017. A total solar eclipse swept across a narrow portion of the contiguous United States from Lincoln Beach, Oregon to Charleston, South Carolina. A partial solar eclipse was visible across the entire North American continent along with parts of South America, Africa, and Europe.
