  • IGR J17591-2342 second re-brightening observed with NICER (21 Sep 2018)
    NICER observations of the second re-brightening of the accreting millisecond pulsar IGR J17591-2342 show it reaching its highest flux yet seen, with strong pulsations remaining after almost 60 days post-outburst.
  • NICER Guest Observer Program approved by NASA (07 Sep 2018)
    NASA has approved a Guest Observer program for NICER. We expect that the Announcement of Opportunity will be released this fall, with proposals due by the end of the calendar year. More information will be posted on the NICER home page when available.
  • NICER and NuSTAR Identification of X-ray Transient IGR J17591-2342 (17 Aug 2018)
    Observations by NICER and NuSTAR of the X-ray transient IGR J17591-2342 discovered by INTEGRAL on August 12 show that the new transient is an accreting millisecond pulsar in outburst. The pulsar has a spin frequency of approximately 527 Hz and an orbital period of 0.37 days.
  • A Rapidly Spinning Black Hole with a Warped Disk (17 Jul 2018)
    NICER provides a detailed look at a rapidly-spinning black hole feeding off its companion star.
  • NASA's NICER Mission Finds an X-ray Pulsar in a Record-fast Orbit (11 May 2018)
    Scientists analyzing the first data from the Neutron star Interior Composition Explorer (NICER) mission have found two stars that revolve around each other every 38 minutes. The discovery bestows the stellar pair with the record for the shortest-known orbital period for a certain class of pulsar binary system.
