IT'S ASTROTIME!

WHAT'S THAT?

IS IT ALIENS?

Nope, it's even cooler than that... It's gravity

I saw this image (thanks @AstroRJS and @SpaceGeck) and I new I had to share it with you all.

This is an Einstein Ring - I haven't given too much detail in the video specific to this image and I recommend you check Russell's thread

Here is another BEAUTIFUL example of this phenomenon (called Gravitational Lensing)

This is called the "The Cheshire Cat Group of galaxies": see the two eyes and the weird smile???

Well the smile (and the other stretchy bits) are DISTANT GALAXIES

3/6

They are being stretched and distorted by the strong gravity of an object (or several), which we call the lense

Lenses can many things so long as they have strong gravity: black holes or even whole galaxies!

@NJRattenbury knows a thing or two about those

Another really cool gravitational lensing result just came out! Check out this @ESO announcement

Why is it so cool? Because we saw a galaxy 12 BILLION light years away that wasn't NEARLY as chaotic as we thought it ought to be

Less than 2 billion years after the big bang, galaxies are not expected to be like the ones in our current Universe. But this gravitational lensing even showed us a baby galaxy with organised features similar to our Milky Way
