NuSTAR

In NGC 6946, better known as the Fireworks galaxy, an extremely bright flare of X-rays was seen to appear and disappear within a matter of weeks.

Sometimes, like galactic bumper cars, galaxies smash into each other. When they do, the massive black holes at their centers usually behave a certain way. However, a merger of two galaxies observed by some NASA spaced-based tech shows that there's always an exception to the rule.

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) observatory has discovered 40 previously unknown X-ray binaries in the nearby Andromeda galaxy (M31).

Observations carried out by NASA's Swift and Nuclear Spectroscopic Telescope Array (NuSTAR) space telescopes may have located the source of intense X-ray bursts emitted by supermassive black holes.

Supermassive black holes are titans of oddity. Now observations from NASA and ESA space telescopes are shedding light on the cosmic winds they produce with more energy than an entire galaxy.

Astronomers have used NASA’s NuSTAR telescope to detect the brightest-ever recorded pulsar. The distant object was happened upon by the team while observing a recent supernova in the region. In the long run, the discovery may improve our understanding of how black holes grow.

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) is unraveling the mystery of how stars go supernova by mapping the remnants of radioactive material left in the wake of a supernova.

The NuSTAR x-ray space telescope has allowed the near-light rotation speed of supermassive black holes to be definitively measured for the first time.

NASA'a NuSTAR space telescope detects black holes through their x-ray emissions.
