The Hubble Space Telescope is being photobombed by artificial satellites every two to four hours, according to researchers at the Space Telescope Science Institute in Baltimore. The satellites leave streaks across images, but the institute has developed a new tool based on the Radon Transform image analysis technique to identify and remove them. The tool is up to 10 times more sensitive than previous software and identifies twice as many trails as other studies. While the number of satellites circling Earth is expected to rise tenfold by 2030, the institute’s tools will still be useful, said Dave Stark of STScI.
