A brilliant "ring of
fire" has been spotted in deep space, giving astronomers a rare glimpse of
a galaxy 12 billion light-years away.
The ring we see in this image was created by a galaxy called SDP.81 giving off light 12 billion light-years away and a closer one, which sits 4 billion light-years from Earth and warps space-time to create the light-bending lens. This was captured at the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile last October.
Researchers note that the resolution they attained from ALMA is unprecedented, and compared it to taking a picture of the rim of a basketball hoop sitting at the top of the Eiffel Tower from the Empire State Building observation deck.
