NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), led by Caltech and managed by JPL, turned 10 years old in June. This space telescope detects high-energy X-ray light and studies some of the most energetic objects and processes in the universe.

The Nuclear Spectroscopic Telescope Array, or NuSTAR, is the first space telescope capable of taking focused high-energy X-ray observations of the cosmos, providing unprecedented information on the dynamics of black holes, exploding stars, and the most extreme active galaxies. Watch a recording of the presentation on YouTube to learn how NuSTAR has expanded our knowledge of the universe after almost a decade of operation.

The selection of proposals for NuSTAR General Observer (GO) cycle-8 has been announced. 81 proposals were selected from the 165 proposals submitted to cycle-8 and include joint coordinated observations with the XMM-Newton, Gehrels-Swift, and NICER observatories.

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.

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.
