News Release • November 10, 2021
Astronomers have discovered a new way to determine the current expansion rate of the Universe, known as the Hubble constant, using X-ray observations of supermassive black holes at the centre of distant galaxies that are gobbling up huge amounts of gas, known as active galactic nuclei. This could settle an on-going dispute between the two existing methods, which disagree on the age of the Universe by more than a billion years.

NASA has announced the eighth 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 eighth cycle of the NuSTAR GO program are due on January 28th, 2022.

With the goal of understanding why the Sun’s corona is so much hotter than its surface, NuSTAR obtained high-energy X-ray observations of the solar corona in coordination with the July 30th suborbital sounding rocket flight of the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) low-energy X-ray instrument.

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.
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.
