Explanation: What are the unusual spots surrounding that galaxy? They are all images of the same supernova. For the first time, a single supernova explosion has been seen split into multiple images by the gravitational lens deflections of intervening masses. In this case the masses are a large galaxy and its home galaxy cluster. The featured image was captured last November by the Earth-orbiting Hubble Space Telescope. The yellow-hued quadruply-imaged Supernova Refsdal occurred in the early universe far behind the cluster. Measuring the locations and time-delays between the supernova images should allow astrophysicists to recover the amount of dark matter in the galaxy and cluster. With patience and luck, a fifth image of the supernova will also be recovered nearby in the next few years.

This was discovered late last year, and just hitting the news recently. Lensing is pretty common, as are extragalactic supernovas, but this is a first for both at the same time. I’m assuming that the supernova is actually behind the galaxy that it appears in, but they haven’t made it exactly clear yet.
Correction I just read somewhere else that it is actually behind.
If Dark Matter exists on this website then that would account for the appearance of multiple images of posts (which has been getting more and more common lately.)
These are not as previously thought the product of multiple hits on the “Post” button by the members but rather he lensing of the comments in question.
At LAST ... a common sense explanation !

DAMN that he lensing .... should’a held out for the she lensing.

The time delay is noticeable due to the vast distances covered in intertube travel.

:’) Typos, they’re everywhere! ;’)
Trillions of stars in the sky, and a few slightly resemble each other? MISS! Einstein, wrong again! Yes, I am an Einstein Denialist! ;')
