The Hubble Space Telescope images the cosmos from low Earth orbit, but an abundance of artificial satellites circle the planet at higher altitudes.

Satellite trails plague astronomy observations, but Hubble Space Telescope scientists figured out a way to reduce the impacts on HST images.

A new technique could aid Hubble Space Telescope users, but the problem will get worse for observatories on Earth.

Astronomers at STScI in Baltimore have developed new software tools to reduce the adverse impact of satellites on images captured by Hubble.

A clear sky is a prerequisite for most astronomers imaging the cosmos. However, with the proliferation of satellite trails, astronomers see a lot more streaks in their images. That's particularly true for people using professional ground-based and orbiting telescopes. When Hubble Space Telescope opened its eye on the sky, there were less than 500 satellites orbiting our planet. Now, there are nearly 8,000 of them, leaving their mark across the sky.
