A record-breaking radio burst from the Sun in August 2025 came from a structure in the Sun's atmosphere called a helmet stream. This image, taken during the total solar eclipse on August 21, 2017, shows the classic V-shape of a large helmet stream. Credit: Miloslav Druckmüller, Peter Aniol, Shadia Habbal/NASA Goddard, Joy Ng

NASA detected a solar radio burst that lasted 19 days

  • No comments
An unusual radio signal from the sun has lasted for 19 days, far beyond the normal duration of such bursts. NASA has linked the event to a giant magnetic structure in the sun's atmosphere, and it could help improve predictions

Artificial Intelligence for Solar Wind Forecasting: New Model Improves Space Weather Warnings

  • No comments
Researchers from NYU Abu Dhabi trained an artificial intelligence model on ultraviolet images from NASA's Solar Observatory and were able to predict solar wind speeds up to four days in advance – with an accuracy that is dozens of times higher.
