The galaxy cluster Abell 1689 is famous for the way it bends
light in a phenomenon called gravitational lensing. A new study of the
cluster is revealing secrets about how dark energy shapes the universe. Full story.

They have already come up with a design that would incorporate the spy telescope into the proposed Wide Field Infrared Survey Telescope (WFIRST), a high-priority NASA mission that would hunt for dark energy, exoplanets and supernovae.
Though a final review and analysis won't be released until April, the new design based on the donated scopes would boost WFIRST's abilities significantly, some researchers say. But the concept could also require more power and a bigger launch vehicle, potentially raising the project's roughly $1.5 billion price tag.
