New solar telescope image reveals sun’s hidden dangers, and could help protect our technology

“When powerful solar storms hit Earth, they impact critical infrastructure across the globe and in space. High-resolution observations of the Sun are necessary to improve predictions of such damaging storms,” says Carrie Black, NSF National Solar Observatory

What you need to know about this story...

  • Scientists have just captured the sharpest-ever image of the Sun’s surface, revealing sunspots that can signal powerful solar storms.
  • It was captured by an instrument on the Daniel K. Inouye Solar Telescope, the most powerful solar telescope on Earth
  • The instrument that captured the image, called the Visible Tunable Filter, acts like a super-powered camera, letting us see details on the Sun as small as 10 km across.
  • These sunspots and solar storms can disrupt satellites, GPS, power grids and even the internet here on Earth, so understanding them matters to everyone.
  • The technology behind this telescope could help us predict and prepare for solar storms before they cause costly blackouts or communication failures.
  • This breakthrough brings us closer to understanding how the Sun affects our daily lives and how we can protect our planet from its outbursts.
