For days, astronomers have been monitoring a large filament of magnetism stretching across the face of the sun. On April 28th, it erupted.

Fragments of the filament flew away from the Sun, creating a "canyon of fire" in the sun's atmosphere and hurling a bright CME into space.

NASA's Solar Dynamics Observatory captured not only imagery of the filament that snaked across a huge area on the Sun but also a strange UFO-like object near the Sun.
