A beautiful image of the recent brief lunar eclipse, taken by Rolf Wahl Olsen from his observatory in Auckland, New Zealand. This was the shortest total lunar eclipse of the century, as the total phase of April 4, 2015 lasted less than 5 minutes.
Using a gradient filter on imagery captured by NASA’s Solar Dynamics Observatory, scientist were able to enhance places of contrast around the sun, making its explosive plasma loops not only more stunning, but also easier to study.
These huge arcs of solar material, which are constrained by magnetic fields, can swirl slowly on the edge of the sun for hours, sometimes even days.
