<\/p>\n NASA<\/p>\n <\/span>\n<\/div>\n<\/p><\/div>\n There are new, high-quality images of Jupiter’s moon, Io, thanks to the nearest flyby of the celestial body by a spacecraft in decades.<\/p>\n NASA released images Saturday taken by the Juno spacecraft, which had been slated to fly roughly 930 miles from the surface of Io, the agency said.<\/p>\n The photos of a silhouetted, dusty red sphere pockmarked by massive grayish volcanoes prompted awe online among astronomers and other stargazers, some of whom called the images “magnificent” and “beautiful.”<\/p>\n The photos were captured by the JunoCam imager, a public engagement tool that’s capable of taking visible-light color images, and which NASA says has been weakened by the effects of radiation during the course of its mission.<\/p>\n
