Black hole’s corona disappearing act; white dwarf hurtling across Milky Way; SDSS fills in gap in expansion history; new image of CMB continues age debate; using science to analyze art

Join us today as we examine one possible reason a black hole’s corona may have disappeared. Be on the lookout for a runaway white dwarf whose supernova sent it hurtling across the Milky Way. We take a look at new survey results that fill in an 11-billion-year gap in the expansion of the universe. A new image of the cosmic microwave background suggests the universe is 13.77 billion years old, give or take 40 million years. And as a fun bonus, scientists use celestial sleuthing on a Vermeer painting to determine when it was actually painted.
