Observations of hot stars allow NuSTAR to constrain the properties of the hypothesized axion particle, enabling this astrophysics mission to study particle physics and hunt for dark matter.

NuSTAR is using DQ Tau as an extraordinary laboratory to study how the intense radiation from X-ray super-flares affects planet formation in young, forming systems.

A new study using data from NASA's NuSTAR space telescope suggests that Eta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is accelerating particles to high energies - some of which may reach our planet as cosmic rays.
