Not just one, but a whole cluster of galaxies shines in this week’s HubbleFriday image!
The streaks of light are actually images of even more distant galaxies, and are the result of an astrophysical phenomenon known as gravitational lensing. This occurs when the gravity of a massive cosmic object (like a galaxy cluster!) is so strong it affects the path of light passing through it. More in the comments :
