The NuSTAR General Observer (GO) cycle-7 proposal selection has been released. The full list of proposals, targets, and exposure times is available from the NuSTAR GO website at HEASARC. Cycle-7 observations are planned to commence on June 1st, 2021.

Astronomers are investigating the mystery of the “soft excess” of low-energy X-ray emission often seen from accreting supermassive black holes. This enigmatic component can carry a large fraction of the X-ray flux, but is poorly understood. Multiple theories have been suggested. Simultaneous observations with NuSTAR (at high energy X-rays) and XMM-Newton (at low-energy X-rays) provide a powerful combination to investigate its origin.

A serendipitous X-ray flare detected by NASA’s Swift observatory is likely associated with a supermassive black hole at the core of a distant galaxy shredding a star that wandered too close.

NASA has announced the seventh opportunity for scientists around the world to propose for observations using the NuSTAR X-ray space telescope. This General Observer (GO) Program is part of an extended mission plan approved by NASA that offers observing time for basic research investigations selected in a competitive process. Proposals for observations to be made within the seventh cycle of the NuSTAR GO program are due on January 29th, 2021.
News Release • September 15, 2020
X-ray observations of a young massive star in a close orbit with the compact remnant of a collapsed star by NASA’s NuSTAR and ESA’S XMM-Newton satellites reveal properties of extreme stellar winds and improve our understanding of how stars evolve.

NuSTAR is seeking letters of self-nomination for people to rotate onto the NuSTAR Users' Committee (NUC). The NUC provides community advice and feedback to the project and NASA Headquarters, and helps ensure the interests of the guest investigator community are well-served by the project. Due date for self nomination letters is October 2nd, 2020.
News Release • July 29, 2020
NASA’s NuSTAR satellite has observed the faintest growing supermassive black holes in our cosmic backyard, and found that some of them are actually luminous “monsters” hiding behind thick clouds of dust and gas.

Astronomers tend to have a slightly different sense of time than the rest of us. They regularly study events that happened millions or billions of years ago, and objects that have been around for just as long. That's partly why the recently discovered neutron star known as Swift J1818.0-1607 is remarkable: A new study in the journal Astrophysical Journal Letters estimates that it is only about 240 years old - a veritable newborn by cosmic standards.

Astronomers are observing the changes in the accretion disk around the neutron star X-ray binary 4U 1608-52. The system was tracked as it fades from outburst to quiescence by three NASA space telescopes, with NuSTAR observations suggesting that the disk puffs up and becomes transparent as the outburst fades.
Announcement • April 21, 2020
The selection of proposals for NuSTAR General Observer (GO) cycle-6 has been announced. 78 proposals were selected from the 172 proposals submitted to cycle-6 and include joint coordinated observations with the XMM-Newton, Gehrels-Swift, and NICER observatories.

A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). EHT is an international collaboration whose support in the U.S. includes the National Science Foundation.
News Release • February 20, 2019
In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material. These two monsters should be the most luminous X-ray sources in sight, but a new study using observations from NASA's NuSTAR mission shows that a much smaller object is competing with the two behemoths.

A brief and unusual flash spotted in the night sky on June 16, 2018, puzzled astronomers and astrophysicists across the globe. The event - called AT2018cow and nicknamed "the Cow" after the coincidental final letters in its official name - is unlike any celestial outburst ever seen before, prompting multiple theories about its source.
