Neutron-rich material is ejected from the disk, enabling the rapid neutron-capture process (r-process). The light blue region is a particularly fast ejection of matter, called a jet, which typically originates parallel to the disk's rotation axis. (National Radio Astronomy Observatory, USA)

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)
