![]() It is a hot, dense white dwarf star, according to NASA. This image released by NASA on Tuesday, July 12, 2022, shows the Southern Ring Nebula for the first time in mid-infrared light. ![]() Then the lengthy process began to align the mirrors, get the infrared detectors cold enough to operate and calibrate the science instruments, all protected by a sunshade the size of a tennis court that keeps the telescope cool. It launched into space in December from French Guiana in South America and reached its lookout point 1 million miles from Earth in January. They are now working to determine how other micrometeoroids could impact Webb’s mirrors, how many of these asteroid fragments there are, and whether the telescope should be adjusted to spend less time pointing toward orbital motion, where it may be at greater risk of being struck by a micrometeoroid.ĭepending on its fuel usage, and expected degradation to the telescope, Webb could survive for more than 20 years, according to engineers. The damage to C3, however, has engineers investigating whether the impact was rare, meaning it could happen once every few years, or if Webb is “more susceptible to damage by micrometeoroids than pre-launch modeling predicted.” Webb has been hit by at least six micrometeoroids since its December launch, equal to roughly one impact per month, matching expectations, according to their report.
