Nova Remnant

A nova remnant is made up of the material either left behind by the gigantic explosion of a star in a nova, or from the bubbles of gas blasted away in a recurrent nova. It has an expansion velocity of around 1000 km/s, and has a lifetime of a few centuries. Considering their short lifetimes, nova remnants usually do not exist anymore by the time their light reaches us. Nova remnants are much less massive than supernova remnants or planetary nebulae.

Famous quotes containing the words remnant and/or nova:

    The remnant of Indians thereabout—all but exterminated in their recent and final war with regular white troops, a war waged by the Red Men for their native soil and natural rights—had been coerced into the occupancy of wilds not far beyond the Mississippi.
    Herman Melville (1819–1891)

    I’m a Nova Scotia bluenose. Since I was a baby, I’ve been watching men look at ships. It’s easy to tell the ones they like. You’re only waiting to get her into deep water, aren’t you—because she’s yours.
