Strange new features on the Sun revealed in first images from NASA's IRIS telescope

Using its single telescope and spectrograph (a light-separating instrument), IRIS has revealed a series of strange, previously unseen features on our parent star, what NASA describes as “a multitude of thin, fibril-like structures.” The agency, along with the spacecraft’s builders at Lockheed Martin, say they aren’t sure yet what these are, exactly. “There is much work ahead to understand what we’re seeing, but the quality of the data will enable us to do that,” said Alan Title, the principal investigator for the spacecraft at Lockheed Martin.
