Hubble telescope captures amazing sight of distant galaxies
The Hubble Space Telescope is known for capturing amazing images of distant galaxies and stars.
Now, it has captured an unusual sight.
A massive galaxy cluster known as SDSS J1038 +4849 appears to be smiling down from the heavens.
Experts say the two glowing eyes are actually two distant galaxies.
The smile is the result of what astronomists call “strong gravitational lensing,” which happens because the gravitational pull between the two galaxy clusters is so strong that it distorts time and space around them.
The circle forming the face is known as an “Einstein Ring,” named after the man whose theory of general relativity explains this type of phenomena.
