"NASA Detects Gigantic Sunspot Cluster Posing Risk of Powerful Solar Flares"

NASA has detected a large cluster of sunspots, known as AR3576, which has increased in size and could cause strong solar flares, posing risks to spacecraft, astronauts, radio communications, power grids, and navigation signals. The sunspots, larger than Earth, were first discovered at the end of last month and are now facing Earth. NASA's Solar Dynamics Observatory captured a massive solar flare on Friday, and the sunspot group is around 93,200 miles long, nearly four times the circumference of Earth.
