– The most distant star visible to the naked eye is V762 Cas, located about 16,000 light years away.
– Andromeda galaxy is the farthest thing visible to the naked eye, appearing as a fuzzy patch about the size of an outstretched fist over 2.5 million light years away.
– Gamma ray bursts can briefly be visible even from billions of light years away when they flare with intense brightness.
– Telescopes allow us to see dimmer and more distant objects by collecting more light and magnifying images. However, less than 3% of Milky Way stars and 1% of galaxies have been mapped so far.
– The most distant single star detected is Earendel, located over 28 billion light years away from when the universe was only 900 million years old.
– The most distant galaxy detected is JADES-GS-z13-0, located over 33.6 billion light years away from when the universe was 400 million years old.
– Microwave background radiation from 380,000 years after the Big Bang provides a view of nearly the edge of the observable universe. Neutrinos and gravitational waves from the early universe may also be detectable.
