NGC 2955

NGC 2955

NGC 2955 is a spiral galaxy in the constellation Leo Minor about 326 million ly from Earth. It spans roughly 150,000 ly, about 1.5 times the width of our Milky Way. It is receding from us at about 7,026 km/s.

Because its light is 326 million ly from home, you are seeing NGC 2955 as it looked roughly 326 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.
