Explanation:
Can you find
Supernova 1987a?
It's not hard - it occurred in the center of the bulls-eye pattern. Although this
stellar
detonation was seen more than a decade ago,
light from it continues to bounce off nearby
interstellar dust and be reflected to us.
These two rings are thus echoes of the powerful
supernova.
As time goes on, these echoes appear to expand outward from the center.
The above image was created by subtracting a picture taken
before 1987, from a picture taken after.
