Each image, a billion light-years across, shows vast dark matter clumps and voids scattered through the cosmos.

The team from the Canada-France Hawaii Telescope inferred the dark matter’s existence by the way it bends light.

The images were presented at the 219th meeting of the American Astronomical Society in Austin, US.

The four images were taken at four different seasons of the year, each capturing a swath of the sky about as large as a palm held at arm’s length.

SETI Opens All Data and Coding to the Public

The New Scientist reports, “SETIQuest is the product of astronomer Jill Tarter’s TED Prize wish. After being awarded the TED Prize last year, Tarter was given the opportunity to make a single wish before an auditorium full of the top names in technology and design. Tarter wished that they would “empower Earthlings everywhere to become active participants in the ultimate search for cosmic company.”
