Objects outside our galaxy
Is there any object outside our galaxy that can be seen with the naked eye
from earth (in the northern hemisphere)? |

Yes, I had thought of that one, but with a 4.5 magnitude you practically
never see it. Anything else? |

But it might depend on what is meant by 'object' and 'outside'. Lets say there actually is a few objects which appear to be inside our galaxy, and are completely visible to the naked eye, but in reality, this could just be only an illusion. |

Just a bunch of bright stars marking constellations like the Dipper and the Northern Cross because of all the light pollution. Anything else? Gravitional lensing can make really distant objects appear to be closer. Maybe future discoveries will prove that some Milky Way objects light originates from 'outside' the galaxy. |

On a really good night M33, the "Pinwheel" galaxy in Triangulum, may also be glimpsed -- but if you have trouble seeing M31 then I doubt you could see this one at all, as it's not only fainter overall but less concentrated at the centre. From the tropics you can see the Magellanic Clouds in season; they're close enough to our Galaxy to interact with it but are still considered extragalactic objects. -- Odysseus |

If the space between galaxies has no bright stars it would be a
wonderful space area to signal the rest of the intelligent life that they are not alone. From are arm near the rim of our galaxy we could sent a huge very powerful laser with the most intense "green" color that can easily be seen if there are astronomers on the Milky Way,and Andromeda galaxies. At this spacetime we have the rocketry,and the lasers,and should start construction right away. The laser light has to pulse(blink) with a code Beert |

M33 is much fainter. Have you ever watched M31 without telescope? Can you
actually see the star-cloud? I always thought that all those nice pictures of galaxies ware long-exposure. |

I've never seen more than the core without optical aid, but I've seen a fair bit of the disk, perhaps half a degree across, with binoculars. Long-exposure photos show much more than the eye can, even through a largish amateur 'scope, not only extending the disk to about three degrees across, but capturing colour and detail that can't otherwise be resolved. -- Odysseus |

Time for me to pack and get out to do some real watching
