NASA’s NuSTAR uses ‘nuisance’ light

After 10 years fighting back photons in its peripheral vision, a NASA space telescope now has a way to use “nuisance light” to potentially increase its science productivity.

NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) X-ray space observatory successfully gathered information about a super-dense star, known as a neutron star, that was in its peripheral vision.
