NASA scientists have recorded a large cluster of sunspots on the sun’s surface and issued a warning to those wishing to observe them.
fox news report There was also a risk of solar flares on Saturday that could affect spacecraft, radio communications, power grids and navigation signals.
“Real-time images from NASA’s Solar Dynamics Observatory show that a giant sunspot group is currently moving across the Sun. If you have eclipse glasses and good eyesight, you can see it without magnification. (Do not look directly at the sun without proper eye protection!)” NASA Said people posted on social media Friday afternoon.
Video footage shows the sun slowly rotating, revealing sunspots that look like clusters of islands.

The Fox article noted that a massive solar flare occurred in December that sent radiation toward Earth and caused problems with aircraft radio communications.
“The sunspot’s magnetic field is thousands of times stronger than Earth’s,” the article said, adding, “The space agency first discovered the population late last month from NASA’s Perseverance rover on Mars, and now the population is on Earth. facing,” he added.
According to NASA Science Space Place WebsiteSunspots appear black because they are cooler than other areas of the sun.
However, “sunspot temperatures are still very high, approximately 6,500 degrees Fahrenheit,” the page read.
“Why are sunspots relatively cool? That’s because they form where magnetic fields are particularly strong. These magnetic fields are so strong that some of the heat within the sun reaches the surface. “It’s preventing us from doing that.”
Video footage from 2017 show Another sunspot rotating to face the Earth:
Regarding solar flares, NASA says:
Magnetic field lines near sunspots often intertwine, intersect, and rearrange. This can cause a sudden burst of energy called. solar flare. Solar flares release large amounts of radiation into space. If a solar flare is very strong, the radiation it emits can interfere with radio communications on Earth.
“Solar flares are sometimes accompanied by coronal mass ejections (CMEs for short). CMEs are giant bubbles of radiation and particles from the Sun. When the Sun’s magnetic field lines suddenly rearrange, they move at extremely high speeds. and explode into space,” the website says.
