MOND models—which don’t require dark matter—have not previously been able to reproduce the temperature variations measured in the cosmic microwave background (shown here), a relic from the big bang. But now researchers have created a MOND-inspired model that matches these data just as well as dark matter models do. (WMAP Science Team/NASA)

A new theory puts dark matter on the chopping block, possibly upending our understanding of gravity

ALMA, in which ESO is a partner, and the SPHERE instrument on ESO’s Very Large Telescope have imaged GW Orionis, a triple star system with a peculiar inner region. Unlike the flat planet-forming discs we see around many stars, GW Orionis features a warped disc, deformed by the movements of the three stars at its centre. The ALMA image (left) shows the disc’s ringed structure, with the innermost ring separated from the rest of the disc. The SPHERE observations (right) allowed astronomers to see for the first time the shadow of this innermost ring on the rest of the disc, which made it possible for them to reconstruct its warped shape. (ALMA (ESO/NAOJ/NRAO), ESO/Exeter/Kraus et al.)

Scientists believe they’ve discovered a planet that orbits three stars
