Animation showing a wide view of SGR 1830, a magnetar that underwent an outburst in October 2020. NICER measurements from the first day of the event show that the X-ray emission exhibited three close peaks with every rotation. Astronomers think the triple peak occurred when three individual surface regions much hotter than their surroundings spun into and out of our view from Earth. NICER tracked the magnetar nearly every day for more than a month. Over that time, the hot spots dimmed, drifted relative to each other, and two even merged – a phenomenon not seen before.

The Neutron star Interior Composition Explorer (NICER) payload undergoes electromagnetic testing at NASA's Goddard Space Flight Center in Greenbelt, Maryland.Electromagnetic testing serves to verify that NICER’s electrical subsystems do not interfere with each other or with International Space Station electrical systems through, for example, conducted or transmitted emissions. This test also verifies that NICER is not susceptible to malfunction due to the electromagnetic environment of the space station.Two time-lapse videos show the NICER payload deploy during electromagnetic testing and return to its stowed configuration following the tests. ||

This image of the whole sky shows 22 months of X-ray data recorded by NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station during its nighttime slews between targets. NICER frequently observes targets best suited to its core mission (“mass-radius” pulsars) and those whose regular pulses are ideal for the Station Explorer for X-ray Timing and Navigation Technology (SEXTANT) experiment. One day they could form the basis of a GPS-like system for navigating the solar system.Credits: NASA/NICER || NICERNightMoveslabels.jpg (3299x1650) [13.7 MB] ||

Watch how NASA’s Neutron star Interior Composition Explorer (NICER) has expanded our understanding of pulsars, the dense, spinning corpses of exploded stars. Pulsar J0030+0451 (J0030 for short), located 1,100 light-years away in the constellation Pisces, now has the most precise and reliable measurements of both a pulsar’s mass and size to date. The shapes and locations of its hot spots challenge textbook depictions of these incredible objects. Music: "Uncertain Ahead" and "Flowing Cityscape" (underscore).

Two views of a Neutron Star: First, a closeup view of a neutron star cycling before, during and after a gamma ray burst and second, crossing a Protoplanetary Nebula toward an elusive Neutron Star ||

A pulsar is a neutron star which emits beams of radiation that sweep through the earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The "pulses" of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star's rotation axis and its magnetic axis. Pulsars pulse because the rotation of the neutron star causes the radiation generated within the magnetic field to sweep in and out of our line of sight with a regular period. External viewers see pulses of radiation whenever this region above the the magnetic pole is visible. Because of the rotation of the pulsar, the pulses thus appear much as a distant observer sees a lighthouse appear to blink as its beam rotates. The pulses come at the same rate as the rotation of the neutron star, and, thus, appear periodic. ||

A pulsar is a rapidly spinning and highly magnetized neutron star, the crushed core left behind when a massive sun explodes. Most were found through their pulses at radio wavelengths, which are thought to be caused by narrow, lighthouse-like beams emanating from the star's magnetic poles. When it comes to gamma-rays, pulsars are no longer lighthouses. A new class of gamma-ray-only pulsars shows that the gamma rays must form in a broader region than the lighthouse-like radio beam. Astronomers now believe the pulsed gamma rays arise far above the neutron star. ||

This animation takes us into a spinning pulsar, with its strong magnetic field rotating along with it. Clouds of charged particles move along the field lines and their gamma-rays are beamed like a lighthouse beacon by the magnetic fields. As our line of sight moves into the beam, we see the pulsations once every rotation of the neutron star. ||

On May 16, 2024, astronauts Don Pettit and Nick Hague participated in a training exercise at the NBL (Neutral Buoyancy Laboratory) at NASA’s Johnson Space Center in Houston. They were rehearsing activities related to repairing NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station.Before any spacewalk, astronauts practice and refine procedures in the NBL to simulate — as closely as possible on Earth — the conditions under which they’ll complete the task in space.In May 2023, damage to thin thermal shields protecting NICER allowed sunlight to reach its sensitive X-ray detectors. This saturated sensors and interfered with NICER’s X-ray measurements during orbital daytime.The NICER team developed five wedge-shaped patches to cover the largest areas of damage. The plan calls for astronauts to insert these patches into the instrument’s sunshades and lock them in place. ||

On May 16, 2024, astronauts Don Pettit and Nick Hague practiced a repair for NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station. The training exercise took place in the (NBL) Neutral Buoyancy Laboratory at NASA’s Johnson Space Center in Houston.Before any spacewalk, astronauts rehearse activities in the NBL to simulate — as much as possible — the conditions under which they’ll complete the task in space.In May 2023, NICER developed a “light leak,” where unwanted sunlight began entering the instrument. The damage allows sunlight to reach the detectors during the station’s daytime, saturating sensors and interfering with NICER’s X-ray measurements. The damage does not impact nighttime observations.The NICER team developed a plan to cover the largest areas of damage using five patches, each shaped like a piece of pie, to be inserted into the instrument’s sunshades and locked in place. ||

In Spring 2024, scientists and engineers at NASA prepared and packed a patch kit for NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station.In May 2023, damage to thin thermal shields protecting NICER allowed sunlight to reach its sensitive X-ray detectors. This saturated sensors and interfered with NICER’s measurements during orbital daytime.The NICER team designed five wedge-shaped patches to cover the largest areas of damage.
