As Earth's magnetic shield fails, so do its satellites. First, our communications satellites in the highest orbits go down. Next, astronauts in low-Earth orbit can no longer phone home. And finally, cosmic rays start to bombard every human on Earth.
New efforts to figure out just how fast the universe has expanded since the Big Bang, a speed known as the Hubble constant, could upend current theories of physics, according to some scientists.
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.
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.
Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning - all in a package that’s around a thousandth of the size of current accelerators. All that's left is for scientists to build one.
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 reveal a ‘rich zoo’ of such organic molecules and provide solid proof of life beyond Earth.
Detailed biomass maps will enable developing countries to better access climate funds.
Thawing ground sends carbon dioxide and methane into the atmosphere.
With environmental changes locked in for several decades, are we too late to save the Arctic?
