In 1987, a huge nearby supernova stunned astronomers. The explosion should have left behind a neutron star, but nobody has ever been able to find it until now Source: https://www.newscientist.com/article/2224110-weve-found-the-missing-neutron-star-at-the-centre-of-a-supernova/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Scientists find evidence of missing neutron star
The leftovers from a spectacular supernova that revolutionised our understanding of how stars end their lives have finally been spotted by astronomers at Cardiff University. Source: https://phys.org/news/2019-11-scientists-evidence-neutron-star.html…
Astronomers catch a record-setting X-ray burst
The sudden spike of X-rays released as much energy in 20 seconds as our sun does in nearly 10 days. Turns out it was a massive thermonuclear flash on a pulsar, the crushed remains of a star that exploded as a supernova long ago.

Thermonuclear Explosion in Sagittarius Constellation Is One of the Brightest Ever Recorded
NASA astronomers have detected one of the brightest explosions of X-ray energy ever seen, and they think it came from a greedy neutron star in the Sagittarius constellation. Source: https://www.livescience.com/brightest-x-ray-explosion.html
NICER catches record-setting X-ray burst
NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station detected a sudden spike of X-rays at about 10:04 p.m. EDT on Aug. 20. The burst was caused by a massive thermonuclear flash on the surface of a pulsar, the crushed remains of a star that long ago exploded as a supernova.

Some of the Universe’s Heavier Elements Are Created By Neutron Star Collisions
sciencehabit shares a report from Science Magazine: Scientists have long suspected that neutron stars, the superdense remnants of burned out suns, are needed for this sort of rapid neutron capture. But until 2 years ago, they had never witnessed such an event. That’s when the GW170817 merger happened. Taking place 140 million light-years away, astronomers first detected it from the gravitational…
First identification of a heavy element born from neutron star collision
For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars. This finding was observed by ESO’s X-shooter spectrograph on the Very Large Telescope (VLT) and is published today in Nature. The detection confirms that the heavier elements in the Universe can form in neutron star mergers,…
PSR J0453+1559 may be a neutron star–white dwarf binary, study suggests
Astronomers have investigated a compact binary radio pulsar system known as PSR J0453+1559, with the aim of shedding more light on its mysterious nature. The new study, published September 26 on arXiv.org, challenges previous assumptions, suggesting that system contains a white dwarf companion.
