Astronomers have made the first measurements of small-scale fluctuations in the cosmic web 2 billion years after the Big Bang. These measurements were conducted using a novel technique which relies on the light of quasars crossing the cosmic web along adjacent lines of sight.
Martin Rees is Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge, the Astronomer Royal, a member of Britain’s House of Lords, and a former President of the Royal Society. The following interview was conducted at Trinity College, Cambridge, by The Conversation’s Matt Warren.
So what has the ERC ever done for us? Quite a lot, say Cambridge academics, as they mark the 10th anniversary of Europe’s premier research-funding body
Astronomers have made the most detailed observation yet of an ultra-fast wind emanating from a Black Hole at a quarter of the speed of light. Using the European Space Agency (ESA)’s XMM-Newton and NASA’s NuSTAR telescopes, the scientists observed the phenomenon in an active galaxy known as IRAS 13224-3809.
An international team of astronomers has found a system of seven potentially habitable planets orbiting a star 39 light years away three of which could have water on their surfaces raising the possibility they could host life. Using ground and space telescopes, the team identified the planets as they passed in front of the ultracool dwarf star known as TRAPPIST-1. The star is around eight per cent of the mass of the Sun and is no bigger than Jupiter.
The Magellanic Clouds, the two largest satellite galaxies of the Milky Way, appear to be connected by a bridge stretching across 43,000 light years, according to an international team of astronomers led by researchers from the University of Cambridge. The discovery is reported in the journal Monthly Notices of the Royal Astronomical Society (MNRAS) and is based on the Galactic stellar census being conducted by the European Space Observatory, Gaia.
