The group behind AnalyzeThis tested their system on complex, real-word workflows, including Montage, a program used to produce astronomical images like this, the Large Magellanic Cloud. This mosaic compiled from the NASA Spitzer Space Telescope was made as part of the Suveying the Agents of Galaxy's Evolution (SAGE). (Credit: NASA/JPL-Caltech/M.

The Planck satellite's full-sky data of hot, ionized dust in the galaxy, shown here, deflated a widely publicized finding of faster-than-light inflation of the universe immediately after the Big Bang. Scanning the sky from its post in Antarctica, the second-generation Background Imaging of Cosmic Extragalactic Polarization (BICEP2) detected a telltale twist in the polarization of microwaves filtering to Earth from space. Thought to reside in the oldest light in the universe, the cosmic microwave background (CMB), the pattern was celebrated as evidence of inflation. But the Planck data showed that the twist was instead introduced by galactic dust. The search for evidence of inflation in the CMB continues. (Image: Planck Collaboration.)
