Space & Universe

The starlight from Andromeda is 2.5 million light years away and so appears extremely dimly to us on earth. In order to make it appear bright like this we have to use very long exposures, minutes, hours, maybe days even to capture enough light. But when we do that we also capture all the light from things that are nearer. If you do that on a moonlit night the sky would literally be white and you wouldn’t be able to pick out any objects in the sky because of the bright white of the sky. 🌌 At 140,000 light years across, it’s 40% bigger than our 100,000 light year diameter Milky Way. If the whole galaxy were bright enough, this is what you’d see at night. (Not to perfect scale and with the moon as a reference) The only galaxy which we can see with our naked eyes, the Andromeda. Andromeda is the closest large galaxy to us! 🌎 Do you love Moon & Andromeda ❤️
