  • NuSTAR Probes Black Hole Jet Mystery (31 Oct 2017)
    Using NASA's NuSTAR space telescope and a fast camera called ULTRACAM on the William Herschel Observatory in La Palma, Spain, Gandhi et al. have been able to measure the distance that particles in the jets from the black hole binaries V404 Cyg and GX 339-4 travel before they "turn on" and become bright in visible light. This distance called the "acceleration zone" is determined to be 0.1 light seconds (30,000 km) in these systems. See the published study in Nature Astronomy.

  • NuSTAR Probes Puzzling Galaxy Merger (28 Mar 2017)
    A supermassive black hole (SMBH) inside a tiny galaxy is challenging scientists' ideas about what happens when two galaxies merge. Was 49 is the name of a system consisting of a large disk galaxy, referred to as Was 49a, merging with a much smaller "dwarf" galaxy called Was 49b. The dwarf galaxy rotates within the larger galaxy's disk, about 26,000 light years from its center. Using NuSTAR, Secrest et al. (2017, ApJ, 836, 183), have discovered that the dwarf galaxy is so luminous in high-energy X-ray, it must host an SMBH much larger and more powerful than expected for such a lightweight.
  • Andromeda's Bright Hard X-Ray Mystery Source Identified by NuSTAR (24 Mar 2017)
    The Milky Way's close neighbor galaxy Andromeda (M 31), features a dominant source of high-energy X-ray emission, but its identity has been mysterious until now. As reported in a new study by Yukita et al. (2017, ApJ, in press), NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) mission has pinpointed the object responsible for this high-energy radiation to be Swift J0042.6+4112, a possible pulsar, the dense remnant of a dead star that is highly magnetized and spinning.
  • NuSTAR Helps Find Universe's Brightest Pulsar (01 Mar 2017)
    The brightest pulsar ever found (NGC 5907 ULX, detected by both XMM-Newton and NuSTAR), has just been reported in the journal Science by Israel et al. (2017). In one second, NGC 5907 ULX emits the same amount of energy (1041 erg) as our sun does in three-and-a-half years. The authors note that standard accretion models fail to explain this high luminosity, but models with strong multipolar magnetic fields can.

  • NuSTAR, Swift and XMM-Newton Help Solve the "Rapid Burster" Mystery (02 Feb 2017)
    Simultaneous Swift, NuSTAR and XMM-Newton observations of MXB 1730-335, a curious neutron star in a binary system known as the 'Rapid Burster', may have solved a 40-year-old mystery surrounding its puzzling X-ray bursts, according to van den Eijnden et al.(2016, MNRAS, 466, L98)). The neutron star magnetic field creates a gap in the accretion disk around the star, largely preventing it from feeding on matter from its companion. Gas builds up there until, under certain conditions, it hits the neutron star all at once, producing intense flashes of X-rays.

  • NuSTAR Feature: A Chorus of Black Holes Sings in X-rays (03 Aug 2016)
    Supermassive black holes (SMBH) in the universe are like a raucous choir "singing" in X-rays. When black holes pull in surrounding matter, they let out powerful X-ray bursts. These "songs" of X-rays, coming from a chorus of millions of black holes, fill the entire sky - a phenomenon astronomers call the cosmic X-ray background. NuSTAR has made significant progress in resolving the high-energy X-ray background, finding that at least 35% is attributable to SMBH, according to a new paper by Harrison et al. (2016, ApJ, in press).
  • NuSTAR CALDB Update (02 Aug 2016)

  • Searing Sun As Seen in the Hard and Soft X-ray and UV Bands (08 Jul 2015)
    The surface of the Sun is lit up in a bouquet of colors in a new composite image containing data from NuSTAR, the Hinode X-Ray Telescope (XRT) and the Solar Dynamics Observatory (SDO). The high-energy X-rays seen by NuSTAR are shown in blue in this image, green represents lower-energy X-rays seen by the Hinode XRT, and yellow and red the UV light viewed by the SDO instruments. Iain Hannah of the University of Glasgow presented this image on July 8, at the UK RAS's National Astronomy Meeting in Wales.
  • NuSTAR Stares Deep into Hidden Lairs of Black Holes (06 Jul 2015)
    Lansbury et al. (2015, ApJ, in press) have used NuSTAR and its hard X-ray capability to observe nine galaxies where supermassive black holes (SMBHs) were thought to be extremely active but largely obscured, at least in the soft X-ray band. Five of these candidates were found to contain hidden SMBHs, feasting on surrounding material. This study supports the theory that potentially millions of SMBHs exist in the universe hidden from view at most wavelengths.
  • Star Explosion is Lopsided, Finds NASA's NuSTAR (08 May 2015)
    The Nuclear Spectroscopic Telescope Array spacecraft has found evidence that the massive star which created supernova SN 1987A exploded in a lopsided fashion, sending ejected material flying in one direction and the core of the star in the other: the 44 Ti gamma-ray emission lines produced in the innermost ejecta are narrow and redshifted by 700 km/s, according to Boggs et al. (2015, Science, 348, 670).
  • NuSTAR Captures Possible 'Screams' from Zombie Stars (29 Apr 2015)
    Peering into the heart of the Milky Way galaxy, NuSTAR has spotted a mysterious glow of hard X-rays that, according to Perez et al. (2015, Nature, 520, 646), could be the "howls" of dead stars as they feed on stellar companions. This hard X-ray emission, sharply peaked on the Galactic Center, "could indicate a significantly more massive population of accreting white dwarfs, large populations of LMXBs or MSPs, or particle outflows interacting with the surrounding radiation field, dense molecular material or magnetic fields."
  • 6th NuSTAR Public Data Release (01 Apr 2015)

  • NASA, ESA Telescopes Give Shape to Furious Black Hole Winds (19 Feb 2015)
    Five simultaneous observations by Nuclear Spectroscopic Telescope Array (NuSTAR) and the XMM-Newton observatory are showing that fierce winds from a supermassive black hole in PDS 456 blow outward in all directions -- a phenomenon that had been suspected, but difficult to prove until now. See Nardini et al. (2015, Science, 346, 860) for the full details.
  • Will the Real Monster Black Hole Please Stand Up? (09 Jan 2015)
    As described in Ptak et al. (2015, ApJ, in press), a new high-energy X-ray image from NuSTAR has pinpointed the 'true' monster in two colliding galaxies, collectively called Arp 299, that are located 44 Mpc away. Each of the galaxies has a supermassive black hole at its heart. NuSTAR has revealed that the black hole located in Arp 299-B, the western of the galaxy pair, is actively gorging on gas, while its partner Arp 299-A is either dormant or hidden under gas or dust.
  • NuSTAR Observes Sun Sizzling in High-Energy X-Rays (22 Dec 2014)
    For the first time, NuSTAR, a mission designed to observe black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of the Sun, and producing the most sensitive solar portrait ever taken in hard X-rays. Future NuSTAR images should provide even better data as the sun winds down its solar cycle and might capture the hypothesized nanoflares that may energize the solar corona.

  • NASA's NuSTAR Telescope Discovers Shockingly Bright Dead Star (08 Oct 2014)
    Bachetti et al. (2014, Nature, 514, 202) used NuSTAR (together with Chandra and Swift) to find a pulsating "dead" star beaming with the energy of about 10 million suns. This is the brightest pulsar ever recorded. The surprising find is helping astronomers better understand the mysterious sources of blinding X-rays, called ultraluminous X-ray sources (ULXs), which, until now, were all thought to be black holes.
  • The Pulse of a Dead Star Powers Intense Gamma Rays (16 Sep 2014)
    When the most massive stars explode as supernovae, they don't fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains? NuSTAR is helping to untangle the mystery.
  • NuSTAR Sees Rare "Blurring" of Black Hole Light (12 Aug 2014)
    NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding the supermassive black hole in Markarian 335. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the black hole over a period of just days so that the black hole's intense gravity has blurred and stretched its X-ray emission.
