Watch a ‘solar snake’ slither across sun’s surface ahead of massive eruption

The European Solar Orbiter spacecraft watched an odd snake-like filament crawl across the sun’s surface just before a massive plasma eruption. 

The filament originated in a sunspot, a cooler region on the sun‘s surface where the star’s magnetic field is twisted. The “snake” took three hours to slither across the sun’s disk at a speed of 105 miles (170 kilometers) per second, or 378,000 mph (608,000 km/h) according to a statement (opens in new tab) from the European Space Agency (ESA), which operates the spacecraft. In the time-lapse sequence constructed from images captured by Solar Orbiter‘s Extreme Ultraviolet Imager, the “snake” glides across the disk within a second.
