Black holes can tell us the expansion rate of the Universe

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.

NuSTAR Cycle 8 Proposals Due on January 28th, 2022

Announcement • October 21, 2021

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.

NuSTAR Observes the Sun with MaGIXS

News Release • September 14, 2021

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.

Seeing Some Cosmic X-Ray Emitters Might Be a Matter of Perspective

News Release • July 9, 2021

Known as ultraluminous X-ray sources, the emitters are easy to spot when viewed straight on, but they might be hidden from view if they point even slightly away from Earth.

Uncovering the Hidden Black Holes

News Release • June 25, 2021

A Tale of Two Coronae: Solving the Mystery of the “Soft Excess”

News Release • March 26, 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.

Shredded star may have caused luminous X-ray transient in a galaxy far, far away

News Release • March 12, 2021

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.

Reclusive Neutron Star May Have Been Found in Famous Supernova

News Release • February 23, 2021

What remains of the star that exploded just outside our galaxy in 1987? Debris has obscured scientists’ view, but two of NASA’s X-ray telescopes have revealed new clues.

NuSTAR and XMM-Newton observe a dusty shroud sparkling in X-rays

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.

NUC self nominations 2020

Announcement • September 4, 2020

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.

A Cosmic Baby Is Discovered, and It's Brilliant

News Release • June 17, 2020

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.
