Kavli Institute for Cosmology, Cambridge 28 Apr 2017, 08:20 UTC The most barren regions of the Universe are the far-flung corners of intergalactic space. In these vast expanses between the galaxies there are only a few atoms per cubic meter – a diffuse haze of hydrogen gas left over from the Big Bang. Viewed on the largest scales, this diffuse material nevertheless accounts for the majority of atoms in the Universe, and fills the cosmic web, its tangled strands spanning billions of light years.
Max Planck Institute for Astronomy 27 Apr 2017, 18:00 UTC Astronomers believe that matter in intergalactic space is distributed in a vast network of interconnected filamentary structures known as the cosmic web. Nearly all the atoms in the Universe reside in this web, vestigial material left over from the Big Bang. A team led by researchers from the Max Planck Institute for Astronomy in Heidelberg have made the first measurements of small-scale fluctuations in the cosmic web just 2 billion years after the Big Bang. These measurements were enabled by a novel technique using pairs of quasars to probe the cosmic web along adjacent, closely separated lines of sight. They promise to help astronomers reconstruct an early chapter of cosmic history known as the epoch of reionization.
Kavli Institute for Cosmology, Cambridge 27 Apr 2017, 08:53 UTC A young star recently observed to be surrounded by spiralling gas and dust could be one of the first to show planet formation ‘in action’ via a mechanism once thought to be unlikely. Astrophysicists at the University of Cambridge have used theoretical models to determine the origins of the striking large-scale spiral features surrounding a nearby star.
