(OPINION) NASA has identified a large cluster of sunspots or dark spots on the sun that have grown in size over the last month and could increase the risk of the Earth experiencing strong solar flares.

NASA found the sunspot cluster known as AR3576 in late January from photographs taken by NASA’s Perseverance rover on Mars, according to Fox News.

The magnetic fields of sunspots are thousands of times more powerful than Earth’s.

As CBN News recently reported, the sun’s surface is growing more active, and serious anomalies can happen when that takes place. While that’s great news for amateur astronomers who are set to see some amazing solar fireworks through their telescopes, it could be bad news for power grids and communication satellites circling the Earth.

Solar flares occur when magnetic energy builds up in the solar atmosphere and is released in an intense burst of electromagnetic radiation, according to Space.com.

This burst of energy can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

On Friday, NASA’s Sun and Space X account posted a video showing the sunspots. The spots are usually as large as the Earth. But AR3576 is more than 93,000 miles long or nearly four times the circumference of our planet and more magnetically complex.
