Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace. Now, a team of scientists led by Professor Subir Sarkar of Oxford University’s Department of Physics has cast doubt on this standard cosmological concept.
On the final day of NAM2015, science writer Kulvinder Singh Chadha investigates a new model that generates accurate predictions of irregularities within the Sun’s 11-year heartbeat, suggesting that solar activity could fall by 60 percent during the 2030s to ‘mini ice age’ conditions. Kulvinder also looks back at the lighter moments and highlights of a successful conference.
In his third report from the Royal Astronomical Society’s NAM2015, Kulvinder Singh Chadha examines the Sun in X-ray and ultraviolet wavelengths from three different spacecraft, dons a virtual reality planetarium headset, and investigates if the proposed James Webb Space Telescope (JWST) could discern Earth-sized worlds that are habitable.
