In 1987, humanity took notice The closest supernova Since 1604.
From 165,000 light-years away, the core of a giant blue star has collapsed.
The first signals detected were neutrinos: they arrived in a burst lasting about 12 seconds.
After hours, The light arrivedindicating a supernova collapsing.
Next, we carefully observed the expanding and developing remnants.
In the suburbs, gas shells that exploded centuries ago continue to expand.
Inside, supernova shock waves heat a spherical halo of matter.
Energy injection causes irregular changes in brightness and X-ray and radio emission.
But the inner region of this explosion remains mysterious.
The essence of the collapse Should create huge residue: a neutron star.
Similar supernova 1054 led to today Pulsating crab.
However, there is no neutron star pulsar Associated with SN 1987a.
However, there are two pieces of evidence that suggest this One can develop.
ALMA notes reveal Huge amounts of internal gas And dust.
Indicates a central “hot spot”. The presence of a newborn neutron star.
Now, join JWST, Showcasing her unique looks.
Newly revealed features Includes “crescents” that appear in gas.
Are they regular projectiles or shapes sculpted by magnetic fields?
The evolution of the supernova remnant will eventually reveal the object contained within.
We may be witnessing the formation of the newest pulsar of our local cluster.
