A burst of radiation on the sun's surface that caused "moderate" disturbances with radio communications on Earth was shown in a new video NASA released on Tuesday.
Watch the video above.
The space agency described the April 17 solar flare as "mid-level" and said that it "caused brief radio blackouts." The radiation cannot harm humans, due to the Earth's atmosphere, but it's capable of interfering with communications systems and the electrical grid, NASA said.
NASA's Solar Dynamics Observatory, which has observed activity on the sun since 2010, recorded the footage.
The video shows "several wavelengths of extreme ultraviolet light" that are invisible to the human eye, but were color-coded for viewers.
