Pulsars, a class of neutron star, can spin up to several hundred times per second. Is black hole evaporation negated by black holes absorbing additional material and energy? However, the new NICER studies of J0030 (a millisecond pulsar that revolves 205 times per second) showed that pulsars aren’t that simple. Since 2017, NICER has been conducting observations from the International Space Station (ISS) for the purpose of creating of learning what goes on inside a neutron star. Pulsars, like black holes, are extremely dense but extremely small objects. 22:07 What is a galactic halo? Scientists now want to determine the masses and sizes of several more pulsars besides J0030. 17:50 Could we find debris in the Lagrange Points? Even more impressive is the fact that two teams arrived at similar findings independently of one another. The study focuses on a pulsar called J0030+0451 (J0030), in an isolated region of space 1,100 light-years away in the direction of the constellation Pisces. It tells us NICER is on the right path to help us answer an enduring question in astrophysics: What form does matter take in the ultra-dense cores of neutron stars? The effect also makes the pulsar … Now, using a special X-ray telescope launched to the International Space Station (ISS) in 2017, scientists have been able to map a pulsar and take precise measurements of its size and mass, for the first time. Primordial Black Holes, Episode 687: Open Space 89: Scott Gaudi and the HabEx Mission, Episode 685: Open Space 88: UFO Culture with Author Sarah Scoles. Read our privacy policy. As Zaven Arzoumanian, the NICER science lead at NASA’s Goddard Space Flight Center, expressed: “It’s remarkable, and also very reassuring, that the two teams achieved such similar sizes, masses and hot spot patterns for J0030 using different modeling approaches. Follow us on Twitter: https://twitter.com/universetoday Astronomers Map the Surface of a Pulsar. Astronomers release a black hole family portrait. 04:05 How much dust is in interstellar space? In a series of papers published in the Astrophysical Journal Letters, NICER observed the pulsar J0030, which is 1100 light-years from Earth in the constellation Pisces. Artist’s concept of a pulsar, with 2 jets: narrow, sweeping beams of radiation. | Simulation of a possible quadrupole magnetic field configuration – 2 pairs of oppositely charged poles – for a pulsar with hot spots only in its southern hemisphere. The pulsar map is not just for flaunting your knowledge and adoration of space; the pulsar map is a beautiful, geometric design that does not give off an imposing message. 23:49 Are there gas dwarfs? It tells us NICER is on the right path to help us answer an enduring question in astrophysics: What form does matter take in the ultra-dense cores of neutron stars?”. 05:57 Can we go faster than the Voyagers? Using a revolutionary X-ray telescope aboard the International Space Station, scientists have finally created the 1st pulsar surface "map." But thanks to NICER’s detailed data, open-source tools, high-performance computers and great teamwork, we now have a framework for developing more realistic models of these objects.”. With NICER we can probe the nature of these dense remnants in ways that seemed impossible until now.”. Thanks to NICER’s precision, which is about 20 times that of previous instruments, astronomers are able to measure the arrival of each X-ray from a pulsar to better than a hundred nanoseconds. As Miller explained, these observations would not have been possible without NICER’s precision: “NICER’s unparalleled X-ray measurements allowed us to make the most precise and reliable calculations of a pulsar’s size to date, with an uncertainty of less than 10%.
