Scientists announced today that they have successfully measured a B-mode polarization signal in the Universe’s cosmic microwave background (CMB). The signal, detected using a telescope at the South Pole, represents an important confirmation of the theory of cosmic inflation and provides insights into how the Universe may have behaved in the first fractions of a […]
Astronomers have pushed the Hubble Space Telescope to it limits by finding what they believe to be the most distant object ever seen in the universe – a mini-galaxy at a distance of 13.2 billion light years that formed only 480 million years after the Big Bang. Writing about their observations in Nature, the team […]
The Hubble Space Telescope has broken the distance limit for galaxies by uncovering a primordial population of ultra-blue galaxies whose light is reaching us now after 13 billion years – just 600 to 800 million years after the Big Bang. Estimating the age of the newly found galaxies was made possible by combining Hubble’s Ultra […]
Physicists from the Institute of Physics of Cantabria (IFCA) and the University of Cambridge may have discovered an example of a cosmic defect, a remnant from the Big Bang called a “texture”. Reported in Science, the discovery could provide dramatic new insights into how the universe evolved following the Big Bang. Professor Neil Turok of […]
The disturbing lack of evidence of microwave “shadows” from nearby galactic clusters is raising new questions about the faint glow of microwave radiation once hailed as proof of the Big Bang theory. The scientists, from the University of Alabama in Huntsville (UAH), used new, highly accurate measurements of the cosmic microwave background from NASA’s Wilkinson […]
An unexpected discovery may see physicists heading back to the drawing board in order to update models representing the Universe immediately after the Big Bang. In an experiment not previously possible, physicists have created the state of matter thought to have filled the Universe just a few microseconds after the Big Bang. To their astonishment, […]
