Weird trivia for children: They Think They Can Fly
The naked eye can indeed see celestial bodies outside the Milky Way, but they are not individual stars, but galaxies “at the same level” as the Milky Way (those seemingly cloudy galaxies are also called “spiral galaxies”).
Among the extragalactic galaxies, the most well-known is the Andromeda Galaxy M31. It is the only “big galaxy” outside of the Milky Way that we can usually see (it has 7 companion galaxies, such as M32 and M110).
The Andromeda Galaxy M31 is the main galaxy in the local group of galaxies (including about 30 galaxies). Together with our Milky Way, it concentrates most of the mass of the local group of galaxies. Its apparent magnitude is 4.36 (the smaller the value, the higher the brightness), and it is about 2.54 million light years away.
For us who live in a corner of the Milky Way, the center of the Milky Way is always dark in the optical band.
Assuming all conditions permit, the most distant celestial body visible to the naked eye is the Triangulum Galaxy M33. It is close to the Andromeda Galaxy and is the third largest galaxy in the local group of galaxies. The Triangulum galaxy M33 is 2.95 million light-years away, farther and darker than the Andromeda galaxy, with an apparent magnitude of only 5.72, making it difficult to see.
The star Kepler-444 and its planetary system are located about 117 light years from the earth in the constellation Lyra on the celestial sphere
