Illustration of the Sun's atmosphere, made visible during a total solar eclipse. The Sun's atmosphere consists of the chromosphere and a much more tenuous and significantly hotter corona (meaning 'crown'). Neither is directly visible from Earth becau...

Digital illustration of the solar atmosphere revealed during a total eclipse of the Sun. A large flare or a coronal mass ejection is seen on the left. This image was commissioned for the cover of the journal Nature for an annual feature called Nature...

This is a 3D illustration of the Sun, showing its turbulent surface and atmosphere as seen at ultraviolet wavelengths. Cooler, dense plumes of plasma (such as filaments and prominences) occur above the visible surface of the Sun, and are seen in the ...

This is a 3D animation of the Sun, showing its turbulent surface and atmosphere as seen at ultraviolet wavelengths. Cooler, dense plumes of plasma (such as filaments and prominences) occur above the visible surface of the Sun, and are seen in the upp...

Illustration of a coronal mass ejection emanating from the Sun. These events, CMEs for short, are powerful releases of solar charged particles (plasma) and magnetic field, travelling on the solar wind. When a CME hits Earth, it can cause a geomagneti...
