A machine on Earth capable of recreating the conditions inside the sun's heart is helping scientists study how iron behaves at mind-boggling temperatures. The results of the experiment, so far, have defied expectations and just might help settle a long-standing solar puzzle.
Celebrate the Year of the Sunflower with beautiful images and fun facts about the yellow beauties.
NASA's Nuclear Spectroscopic Telescope Array has turned its gaze from distant black holes and focused on our sun, producing the most sensitive measurement of high-energy solar X-rays ever achieved.
