NGC 4834

NGC 4834 is a spiral galaxy in the constellation Canes Venatici about 524 million ly from Earth. It spans roughly 160,000 ly, about 1.6 times the width of our Milky Way. The light reaching us tonight left it about 524 million years ago.

Because its light is 524 million ly from home, you are seeing NGC 4834 as it looked roughly 524 million years ago. The photons left before that much of history had passed, and are only now reaching us. This distance is estimated from the galaxy's redshift, so the lookback time is approximate.
