Video of Neutron Stars: Crash Course Astronomy #32
FAST is so big it s sensitive to fainter pulsars than have ever been seen before. The survey scans the plane of the Milky Way to look for them high mass stars that explode as supernovae and form neutron stars tend to be pretty much right along the disk of the galaxy. We are inside the galaxy, so we see this disk as a thick line across the sky (called, confusingly, the Milky Way) and so that s the best place to look for pulsars.

It found some interesting ones, too. 40 of the new found pulsars are what we call millisecond pulsars, spinning faster than about 300 times per second.
A highly-detailed VLA image indicates that the jets of material propelled outward by young stars much more massive than the Sun may be very different from those ejected by less-massive young stars.

On 24 February 1987, a star exploded in the Large Magellanic Cloud, the first supernova visible to the unaided eye in nearly 400 years. Known as SN 1987A, the spectacular blast generated world-wide interest as astronomers scrambled to study the aftermath of the explosion some 170,000 light years from Earth.
Now, more than three decades after the fact, astronomers may have finally found signs of the collapsed remnant of the doomed star in multiple observations suggesting the presence of a “pulsar wind nebula” made up of charged particles and magnetic fields generated by a spinning neutron star.

Reclusive Neutron Star Thought Found among Debris of Famous Supernova
Astronomers now have evidence from two X-ray telescopes (Chandra and NuSTAR) for a key component of a famous supernova remnant.
Supernova 1987A was discovered on Earth on February 24, 1987, making it the first such event witnessed during the telescopic age.
For decades, scientists have searched for a neutron star in SN 1987A, i.e. a dense collapsed core that should have been left behind by the explosion.
This latest study shows that a pulsar wind nebula created by such a neutron star may be present.
