WebProper-motion observations covering the period 1942-1976 show that the expansion time scale for the optical remnant of SN 1604 is greater than the order of 10,000 years. This indicates that the remnant consists of circumstellar material that was excited by the supernova shell. The optical remnant is found to have a tangential velocity of 525 + or - … Web20 nov. 2015 · In the case of the Veil, we want to know its age. Its age is equal to the distance the nebula has expanded divided by the rate at which it’s expanding. One way we can figure out the rate at which its expanding is by observing the nebula over time and seeing how much it has expanded in that amount of time. Of course this isn’t always …
