Using a relatively small telescope, NASA scientists were able to capture images of an active region of the sun. Other telescopes focus on larger swaths of the sun, while this one zoomed in on 'real fine structure'.
While many NASA space telescopes soar in orbit for years, the agency's diminutive Hi-C telescope tasted space for just 300 seconds, but it was enough time to see through the sun's secretive atmosphere.
Designed to observe the hottest part of the sun — its corona — the small High-Resolution Coronal Imager (Hi-C) launched on a suborbital rocket that fell back to Earth without circling the planet even once. The experiment revealed never-before-seen "magnetic braids" of plasma roiling in the sun's outer layers, NASA announced today (Jan. 23)
"300 seconds of data may not seem like a lot to some, but it's actually a fair amount of data, in particular for an active region" of the sun, Jonathan Cirtain, Hi-C mission principal investigator at NASA's Marshall Space Flight Center in Huntsville, Ala., said during a NASA press conference today.
The solar telescope snapped a total of 165 photos during its mission, which lasted 10 minutes from launch to its parachute landing.
