NASA captured an image of the sun emitting a powerful solar flare that could interfere with technology on Earth.

Solar flares and other solar activity, such as solar storms, are only expected to become more common by 2025 as the Sun reaches the height of its 11-year cycle, known as the solar maximum.

Solar flares measured around X1 — like the May 13 and 14 events — indicate strong flare intensity. An X10 flare is described as as a severe event, according to NOAA.

Solar flares are ranked on a scale from A to X, Space.com reports, with X-class flares being the most powerful and each rank up represents a tenfold increase in strength.

Recent solar flares in 2022. The strength and frequency of flares, along with many other aspects of solar activity, varies in a "solar cycle" that lasts roughly 11 years.

Solar flares are classified based on their strength, much like earthquakes, according to NASA.The scale ranges from B-class on the lowest end to C-class, then M-class, and finally, X-class.
