Architecture of DF2 and DF4 systems. a, the radial velocity difference between DF2 and DF4 is 358 km s−1 This large difference in speed is accompanied by a large line-of-sight interval of 2.1 ± 0.5 megabytes per inch. The geometry indicates that the galaxies are moving away from each other. Tracking their positions in time, … Read more
Frank Wilczek has a special fondness for rainbows. It’s not just rainbows stretching across the sky that catch the Nobel Prize winner’s attention. He is equally amazed by the range of colors that appear on soap bubbles, water sprays and in prisms. “There are rainbows everywhere, once you start paying attention,” he said recently from … Read more

Artist view of the COBE satellite. Credit: Matthew Verdolivo, University of California, Davis New research suggests an invisible “mirror world” of particles interacting with our world only via gravity may be the key to solving a great mystery in cosmology today – the problem of the Hubble constant. The Hubble constant is the rate of … Read more
Credit: CC0 Public Domain New research led by the University of Cambridge is the first to take a detailed image of an unusual pocket of rock in the boundary layer with the Earth’s core, about three thousand kilometers below the surface. The mysterious region of rocks, located almost directly below the Hawaiian Islands, is one … Read more
meIf you’re a science journalist, you obviously can’t go wrong when you get an exclusive story combining Stephen Hawking and black holes and solving one of science’s biggest paradoxes. And so the BBC’s science correspondent of 24 years and honorary president of the Society of British Science Writers, Balab Ghosh, got his hands on it. … Read more
Researchers led by the University of Iowa have learned how a type of aurora borealis forms on Mars. In a new study, physicists report a separate aurora formation through the interaction of the solar wind and crust in Mars’ southern hemisphere. Credit: CU/LASP.
