A new space telescope designed to peer into some of the farthest regions of the universe could finally answer one of the most puzzling questions surrounding Albert Einstein’s general theory of relativity. The Euclid mission, which is due to be launched by the European Space Agency in 2021, will capture images of billions of distant … Read more
Scientists are hoping to understand one of the most enduring mysteries in cosmology by simulating its effect on the clustering of galaxies. That mystery is dark energy – the phenomenon that scientists hypothesise is causing the universe to expand at an ever-faster rate. No-one knows anything about dark energy, except that it could be, somehow, blowing … Read more
Detailed simulations of planetary formation are revealing how tiny grains of dust turn into giant planets and could shed light on where to find new Earth-like worlds. Scientists theorise that planets form from rotating discs of gas that surround newly formed stars, known as proto-planetary discs. Pebble-sized objects in these discs then clump together to … Read more
The most mysterious phenomenon in cosmology – dark energy – may not exist at all, according to Professor Subir Sarkar, head of the particle theory group at the University of Oxford in the UK. In the late 1990s, astronomers found evidence from supernovae that the universe has been expanding faster and faster as it gets … Read more
Mysterious radiation emitted from distant corners of the galaxy could finally be explained with efforts to recreate a unique state of matter that blinked into existence in the first moments after the Big Bang. For 50 years, astronomers have puzzled over strange radio waves and gamma rays thrown out from the spinning remnants of dead … Read more
There are likely to be many more ingredients for life on Saturn’s moon Enceladus than those identified so far, says Dr Frank Postberg from the University of Heidelberg, Germany, the lead author of a paper published on 27 June which revealed the presence of complex carbon-based molecules in the moon’s core. He says a fresh mission could … Read more
