Between 2002-2005, 2.8 percent of the longer exposures taken by Hubble contained a satellite track. By 2018-2021, that fraction rose to 4.3 percent. Wide Field Camera 3, ...

This image captures the streak of an Earth-orbiting artificial satellite crossing Hubble’s field of view during an observation of “The Mice” interacting galaxies (NGC 4676).

Though Hubble is covered when it comes to editing satellites’—uh, light— out of imagery, astronomers are worried about the noise produced by satellite constellations, like SpaceX’s Starlink.

A raw Hubble image shows a satellite streak. (NASA / ESA / STScI / Kruk et al. / Nature) An analysis of more than 100,000 images from the Hubble Space Telescope, conducted with the aid of ...

Those 36 satellites will compose Hubble’s first “production constellation,” and they’ll enable connection with a Hubble satellite roughly two-three hours per day from anywhere in the world.

When these satellites pass in front of telescopes like Hubble, they can leave bright streaks across the images due to reflected sunlight which makes the data scientifically useless.

A former spy satellite is now being overhauled by NASA to search for planets beyond the solar system. Once operational—the space agency plans to launch the craft within the next five years—it ...
