This actually all comes courtesy of one telescope, the Chandra X-Ray Observatory, which was first launched into space in 1999. The Hubble telescope was also launched around this time and the two telescopes are still some of the most powerful ones that NASA has developed. NASA continually upgrades both of them with new technology over the years, enabling them to capture incredible photos like the ones now shared.
Chandra differs from the Hubble telescope in part based on their trajectories in space. The Hubble keeps a pretty close orbit to Earth, whereas Chandra is much wider in its path. In its mission to capture images like the ones NASA shared in the latest photos, Chandra can travel as close as 6,000 miles from the Earth all the way up to 86,400 miles away from the Earth. And that is all in just 64 hours of its orbiting cycle.
