NGC 2742A

NGC 2742A

NGC 2742A is a barred spiral galaxy in the constellation Ursa Major about 367 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. It is receding from us at about 7,602 km/s.

Because its light is 367 million ly from home, you are seeing NGC 2742A as it looked roughly 367 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.
