NASA finds Tropical Cyclone Flamboyan in a southeastern stretch

IMAGE: NASA's Aqua satellite provided a visible image of Tropical Cyclone Flamboyan on May 2 at 3:50 a.m. EDT (0750 UTC). The storm is devoid of rainfall with the exception of... view more  Credit: NASA/NRL Strong vertical wind shear had taken its toll on Tropical Cyclone Flamboyan when NASA's Aqua satellite passed over the Southern Indian Ocean. Flamboyan, now a subtropical cyclone, had been stretched out…

A shining star

Nobel Prize laureate David Gross, a permanent member of UC Santa Barbara's Kavli Institute for Theoretical Physics (KITP), wanted to be the first to break the news to KITP Director Lars Bildsten. So, with apologies for the early hour, he phoned his colleague at 6:30 a.m. to congratulate him for being elected a member of the National Academy of Sciences (NAS). Bildsten, who was in…

Taming the multiverse: Stephen Hawking’s final theory about the big bang

Professor Stephen Hawking's final theory on the origin of the universe, which he worked on in collaboration with Professor Thomas Hertog from KU Leuven, has been published today in the Journal of High Energy Physics. The theory, which was submitted for publication before Hawking's death earlier this year, is based on string theory and predicts the universe is finite and far simpler than many current…

IMAGE: The exoplanet WASP-107b is a gas giant, orbiting a highly active K-type main sequence star. The star is about 200 light-years from Earth. Using spectroscopy, scientists were able to find... view more  Credit: ESA/Hubble, NASA, M. Kornmesser Astronomers using the NASA/ESA Hubble Space Telescope have detected helium in the atmosphere of the exoplanet WASP-107b. This is the first time this element has been detected in…

Hawking’s last paper co-authored with ERC grantee posits new cosmology

Professor Stephen Hawking's final theory on the origin of the universe, which he worked on in collaboration with Professor Thomas Hertog from KU Leuven, has been published this week in the Journal of High-Energy Physics. Professor Hertog, whose work has been supported by the EU's European Research Council, first announced the new theory at a conference in Cambridge in July of last year, organised on…

Helium detected in exoplanet atmosphere for the first time

Astronomers have detected helium in the atmosphere of a planet that orbits a star far beyond our solar system for the very first time. An international team of researchers, led by Jessica Spake from the University of Exeter, discovered evidence of the inert gas on 'super-Neptune' exoplanet WASP-107b, found 200 light years from Earth and in the constellation of Virgo. The pivotal breakthrough, made from…
