Last Thursday, the sun delivered the goods, unleashing a beautiful solar flare. The eruptions lasted somewhere around 90 minutes, and the plasma flares were all captured in high def by NASA’s Solar Dynamics Observatory, a project dedicated to studying the sun and its impact on space weather. This footage comes soon after another groundbreaking NASA video – the First 360 Degree View of the Sun.

Beautiful and Dangerous, our sun
the tendency is to imagine the solar surface as flat, but it’s anything but. What is the density at the surface? I imagine it’s like very dense lava.
Wonderful! I just love this video
