High altitude water Cherenkov Observatory tests speed of light![]() Los Alamos NM (SPX) Apr 01, 2020 New measurements confirm, to the highest energies yet explored, that the laws of physics hold no matter where you are or how fast you're moving. Observations of record-breaking gamma rays prove the robustness of Lorentz Invariance - a piece of Einstein's theory of relativity that predicts the speed of light is constant everywhere in the universe. The High Altitude Water Cherenkov observatory in Puebla, Mexico detected the gamma rays coming from distant galactic sources. "How relativity behaves at ... read more |

Jupiter's Great Red Spot shrinking in size, not thickness Paris, France (SPX) Mar 17, 2020
Jupiter, the largest planet in the solar system, is mainly made up of liquids and gases. Its clouds are shaped by jet streams, winds and vortices into numerous parallel bands, as well as coloured patches, one of which clearly stands out: the Great Red Spot. This is an Earth-sized anticyclone that has been observed for over 350 years, but has suddenly decreased in size in recent years.

Precision mirrors poised to improve sensitivity of gravitational wave detectors Washington DC (SPX) Mar 19, 2020
Researchers have developed a new type of deformable mirror that could increase the sensitivity of ground-based gravitational wave detectors such as the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO). Advanced LIGO measures faint ripples in space time called gravitational waves, which are caused by distant events such as collisions between black holes or neutron stars.
