It’s scientifically significant because it presented a great opportunity to study core-collapse supernovae through its different phases. "A pulsar's power depends on how fast it spins and on its magnetic field strength, both of which would need to have very finely tuned values to match the observations," said Page, "while the thermal energy emitted by the hot surface of the young neutron star naturally fits the data. In late February 1987, the light from the closest supernova in four centuries reached Earth. That was difficult, since Hubble didn't focus well back then (subsequent servicing missions installed cameras that corrected for the incorrectly ground primary mirror). Earlier (3-D) observations with ALMA already showed the types of molecules found in the supernova remnant and confirmed that it produced massive amounts of dust. But at the centre, astronomers could find no trace of the expected newborn neutron star. However, an enduring mystery remains: What did SN 1987A leave behind? ", "The neutron star behaves exactly like we expected," added James Lattimer of Stony Brook University in New York, and a member of Page's research team.

Another theory suggested that a pulsar was formed instead, and that its magnetic field was small or unusual, preventing us from detecting it. This is the kind of subatomic particle wind that powers quite a bit of the energy of the Crab Nebula, the expanding debris from a much closer supernova (6,500 light years away) the light from which reached us in the year 1054. Because neutron stars compress about 1.4 times the mass of the Sun into a sphere roughly 15 miles (25 kilometers) wide, they are impossible to see directly. Then, by closely seeking out periodic variations in the blob’s brightness, they might be able to tie any flickers to the consistent rhythm of a pulsar within. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. As it turns out, it’s precisely where they found the blob in the ALMA images.

Since the supernova first became visible, astronomers have been searching for the collapsed core.

Two teams of astronomers, including Department of Physics and Astronomy’s James M. Lattimer, distinguished professor of astronomy, have made a compelling case in the 33-year-old mystery surrounding Supernova 1987A (SN 1987A). This blob is not exactly at the center of SN 1987A, though; it’s slightly offset. Now that astronomers have likely found the location of the neutron star within SN 1987A — and nicknamed it “NS 1987A” — the real quest for understanding can begin. Until then, however, researchers are simply happy that a decades-old mystery about what lurks in the core of SN 1987A is likely laid to rest. The supernova explosion created a massive expanding shock-wave of gas, super-heated to over a million degrees F. As the gas cooled, some of it turned solid, forming a dense cloud of dust. But even so, you can bet astronomers won’t stop tracking the aftermath of the cosmic explosion anytime soon. Where was the neutron star that should lie at the center of the expanding shock-wave? on Reddit, dimmed to a blip of light in the southern sky, Astronomers get a front row seat to a star getting torn apart by a huge black hole, Don't panic! Extremely high-resolution images revealed a hot "blob" in the dusty core of SN 1987A, which is brighter than its surroundings and matches the suspected location of the neutron star. But that’s not a bug in the theory, that’s a feature. "In spite of the supreme complexity of a supernova explosion and the extreme conditions reigning in the interior of a neutron star, the detection of a warm blob of dust is a confirmation of several predictions," Page explained.

These are incredibly dense, hot, and rapidly spinning objects, the mass of more than the entire Sun compressed down into a sphere only a dozen or so kilometers wide.
