Has anyone been to see Godrevy lighthouse on the opposite side of the bay to St Ives? It's a beautiful area with great beaches.
But here's a nighttime shot of the lighthouse and island you don't normally see with the Andromeda galaxy overhead.
Here're some 'mind blown' 🤯 facts about Andromeda to consider whilst getting stuck into your Sunday lunch today.
Andromeda is our nearest neighbouring galaxy, home to about a TRILLION (that's 1,000,000,000,000) stars and it is some 2.5 million lightyears away 😅.
That means we are seeing Andromeda as it was 2.5 million years ago because that's how long the light took to get to us from it (and yes, that's the *nearest* galaxy to us, there are hundreds of billions more galaxies in the universe!).
Also in the shot are the dwarf galaxies M32 and M110, which look like small fuzzy stars to the left and right of Andromeda.
In the distant future, around 4.5 billion years from now, our own galaxy, the one we call the Milky Way, will collide with Andromeda as it's approaching us at a mind-bending speed of 68 miles per second, the result will be a super galaxy called, maybe you already guessed it, 'Milkdromeda' 😂.
However, the distance between the stars in galaxies is so vast that it's unlikely to cause any stellar collisions, so no need to worry about our Sun being hit by another star from Andromeda!
Details about the photo.
On dark, clear nights, you can see Andromeda's bright core with the naked eye, or binoculars as a faint star-like smudge if you know where to look.
But for the best results, you need to take a very long exposure shot from a camera (or multiple exposures and stack them together using special software) which is what I did here to make Andromeda really pop 🤩
