We know of thousands of planets but precisely zero around white dwarfs. White dwarfs are not weird unusual objects but the inevitable fate of over 90% of the stars in our Universe - including the Sun! They're so small and faint that no telescope, even Kepler, has been able to find planets yet. But a new telescope - called LSST - might change all that. Jorge Cortés, a graduate student here at Columbia in the Cool Worlds Lab, tells us today about his new paper where he calculates how feasible it would be for LSST to pull off this last great planet detection trick which has evaded us to date!
