Observations of the Crab Nebula taken over several decades show that gas blobs that are now 100 arcseconds from the center of th

e nebula are moving away from the center by about 0.11 arcsecond per year. Use that information to estimate the year in which the explosion ought to have been observed.

Answer:

Estimation: year 1110.

Explanation:

We need to know how much time it takes to move 100 arcseconds if it moves at 0.11 arcsecond per year. Similarly to any velocity equation v=\frac{d}{t}, where in our case the distances are angular, we will obtain the time by doing:

t=\frac{d}{v}=\frac{100arc}{0.11arc/year}=909 years

Which, considering from 2019, the explosion ought to have been observed around 1110 (in reality it was observed by Chinese astronomers in 1054).
