Artist's Description
G11.2-0.3 is a circularly symmetric supernova remnant that contains a dense, rotating dead star at its center, representing a textbook case of what the remnant of an exploding star should look like after a couple thousand years. When a massive star collapses, the outer layers of the star are blown away in an extremely energetic explosion. Depending on the mass of the original star, a dense object such as a neutron star or a black hole, can form and be left behind at the explosion's center. Such a neutron star, known as a "pulsar" when it rapidly rotates, can be kicked by the thermonuclear shock wave created when the star exploded, causing it to race through space at millions of miles per hour. By combining X-ray and radio observations, astronomers have evidence that G11.2-0.3 is likely the result of the explosive death of such a massive star, perhaps witnessed in 386 A.D. Radio observations measure the remnant's expansion rate, which, in turn, can be used to calculate how long ago the...
