Topic: Neutron Star
Since astronomers captured the bright explosion of a star on February 24th, 1987, researchers have been searching for the squashed stellar core that should have been left behind. A group of astronomers using data from NASA space missions and ground-based telescopes may have finally found it. ![]() Supernova 1987A exploded more than 30 years ago and is still surrounded by debris. The energetic environment has been imaged by NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR (shown in blue) and the Chandra X-ray Observatory (shown in red), which has finer resolution.

NASA picks Four Small Mission Concepts to Study the Universe
“The principal investigators of these concept studies bring innovative, out-of-the-box thinking to the problem of how to do high-impact astrophysics experiments on a small budget,” said Thomas H. Zurbuchen, associate administrator of NASA’s Science Mission Directorate. “Each of the proposed experiments would do something no other NASA telescope or mission can do, filling important gaps in our understanding of the universe as a whole.” ![]() As neutron stars collide, some of the debris blasts away in particle jets moving at nearly the speed of light, producing a brief burst of gamma rays.

NASA’s Swift Observatory discovers newly created Neutron Star
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. NASA’s Neil Gehrels Swift Observatory spotted the young object on March 12th, when it released a massive burst of X-rays. ![]() This illustration shows magnetic field lines protruding from a highly magnetic neutron star, or a dense nugget left over after a star goes supernova and explodes. Known as magnetars, these objects generate bright bursts of light that might be powered by their strong magnetic fields. (ESA) «Read the rest of this article» Sections: Technology | No Comments
NASA Science continues from Home Offices, Video Conferencing in response to Coronavirus
With most personnel supporting missions remotely to keep onsite staff at a minimal level in response to Coronavirus (COVID-19), the Agency is moving ahead strongly with everything from space exploration to using our technology and innovation to help inform policy makers. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Chandra X-ray Observatory data reveals Cosmic Jekyll and Hyde
Using nearly a decade and a half worth of Chandra data, researchers noticed that a stellar duo behaved like one type of object before switching its identity, and then returning to its original state after a few years. This is a rare example of a star system changing its behavior in this way. ![]() Terzan 5 (right), low, medium and high-energy X-rays detected by Chandra are colored red, green and blue respectively. On the left, an image from the Hubble Space Telescope shows the same field of view in optical light. Terzan 5 CX1 is labeled as CX1 in the Chandra image.

NASA’s Chandra X-ray Observatory, Hubble Telescope, Spitzer Telescope photos used to make 3D image of Crab Nebula
The multiwavelength computer graphics visualization is based on images from the NASA Chandra X-ray Observatory, the NASA Hubble Space Telescope and the NASA Spitzer Space Telescope. ![]() This new multiwavelength image of the Crab Nebula combines X-ray light from the Chandra X-ray Observatory (in blue) with visible light from the Hubble Space Telescope (in yellow) and infrared light seen by the Spitzer Space Telescope (in red). This particular combination of light from across the electromagnetic spectrum highlights the nested structure of the pulsar wind nebula. The X-rays reveal the beating heart of the Crab, the neutron-star remnant from the supernova explosion seen almost a thousand years ago. (NASA, ESA and J. DePasquale (STScI) and R. Hurt (Caltech/IPAC)) «Read the rest of this article» Sections: Technology | No Comments
NASA’s NICER telescope records sudden spike of X-Rays
The X-ray burst, the brightest seen by NICER so far, came from an object named SAX J1808.4-3658, or J1808 for short. The observations reveal many phenomena that have never been seen together in a single burst. In addition, the subsiding fireball briefly brightened again for reasons astronomers cannot yet explain. ![]() Illustration depicting a Type I X-ray burst. The explosion first blows off the hydrogen layer, which expands and ultimately dissipates. Then rising radiation builds to the point where it blows off the helium layer, which overtakes the expanding hydrogen. Some of the X-rays emitted in the blast scatter off of the accretion disk. The fireball then quickly cools, and the helium settles back onto the surface.

NASA’s discovers bright Neutron Star among two Supermassive Black HolesNASA Jet Propulsion Laboratory
The most stunning features of the Whirlpool galaxy – officially known as M51a – are the two long, star-filled “arms” curling around the galactic center like ribbons. The much smaller M51b clings like a barnacle to the edge of the Whirlpool. Collectively known as M51, the two galaxies are merging. ![]() Bright green sources of high-energy X-ray light captured by NASA’s NuSTAR mission are overlaid on an optical-light image of the Whirlpool galaxy (in the center of the image) and its companion galaxy, M51b (the bright greenish-white spot above the Whirlpool), taken by the Sloan Digital Sky Survey.

NASA Telescopes used to study unusual Flash of Light nicknamed “The Cow”Written by Jeanette Kazmierczak
Over three days, the Cow produced a sudden explosion of light at least 10 times brighter than a typical supernova, and then it faded over the next few months. ![]() AT2018cow erupted in or near a galaxy known as CGCG 137-068, which is located about 200 million light-years away in the constellation Hercules. This zoomed-in image shows the location of the “Cow” in the galaxy. (Sloan Digital Sky Survey) «Read the rest of this article» Sections: Technology | No Comments
NASA Telescopes discover Electromagnetic waves from a Gravitational Wave SourceNASA’s Goddard Space Flight Center
The discovery was made using data from telescopes including NASA’s Chandra X-ray Observatory, Fermi Gamma-ray Space Telescope, Neil Gehrels Swift Observatory, the NASA/ESA Hubble Space Telescope, and the Discovery Channel Telescope (DCT). ![]() A distant cosmic relative to the first source that astronomers detected in both gravitational waves and light may have been discovered. This object, called GRB150101B, was first detected by identified as a gamma ray burst (GRB) by the NASA’s Fermi satellite in January 2015. (X-ray: NASA/CXC/GSFC/UMC/E.
