Hubble Finds Double Einstein Ring

A recent ESA press release displays a lovely a Hubble image of what is charmingly known as gravitational lens system SDSSJ0946 1006. The gravitational effect of a foreground galaxy is lensing two more distant objects to form this double Einstein ring.

Hubble continues to prove its worth even as it approaches what could be the end of its time. I hope the possible repair missions go ahead and are successful. Hubble is one of the greatest achievements of Humankind in the modern age and should be in use as long as is possible.
