What is SN1987a made of? Supernova? Like what is it made of, gas, stars etc?

Best answer: Plasma and matter. The supernova happened in 1987 when a blue giant star in the Large Magellanic could went supernova. Scientists now suspect there may be a pulsar and not neutron star or balck hole. where the blue giant star WAS. The bow shock wave of matter is still moving away from the conductive and convective layers of the blue giant A pulsar is a type of neutron star.

"...So Supernova 1987A appears to be a core-collapse supernova. That is, as the star exploded, the core of the star should have collapsed. Given the size of the original star, astronomers would have expected a neutron star to form. Neutrino emissions from the supernova event indicate that a compact object did form at the star’s core. To this day, though, although astronomers have searched for the neutron star left behind by the supernova, no neutron star has been found. ...

...Bottom line: Astronomers at the International Centre for Radio Astronomy Research (ICRAR) in Perth, Australia led research leading to a high resolution image of Supernova 1987A at radio wavelengths. Their work suggests that there is no black hole at the center of the supernova remnant, but instead there is a compact source or pulsar wind nebula (a nebula powered by the pulsar wind of a pulsar) at its center...."

Was a star. Went supernova. Now a star core and surrounding gas cloud that is expanding and glowing like a neon sign as it runs into stuff.

A star called "Sanduleak - 69 202 a,

a supernova IS a star.
