A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously thought to be largely off-limits.

Last week, four lasers were projected into the skies above the European Southern Observatory’s (ESO’s) Paranal site in Chile. The lasers are each used to create an artificial star, which astronomers use to measure and then correct the blur caused by Earth's atmosphere. The striking launch of these lasers, one from each of the eight-metre telescopes at Paranal, is a significant milestone of the GRAVITY+ project — a large and complex upgrade to ESO’s Very Large Telescope Interferometer (VLTI). GRAVITY+ unlocks a greater observing power and a much wider sky coverage for the VLTI than previously possible.

The recent test, announced by the European Southern Observatory (ESO) today, mark a significant milestone of the GRAVITY+ project, a complex upgrade to ESO’s Very Large Telescope Interferometer (VLTI), unlocking greater observing power and much wider sky coverage.

X-ray absorption spectroscopy (XAS) provides valuable information about a material’s properties and electronic states. However, it requires extensive expertise and manual effort for conventional analysis. Now, researchers from Japan have developed a novel artificial intelligence-based approach for analyzing XAS data that can enable rapid, autonomous, and object material identification. This novel approach outperforms the previous studies in terms of higher accuracy, accelerating the development of new materials.

New findings from NASA’s Cassini mission show that Enceladus, one of Saturn’s moons and a top contender for extra-terrestrial life, is losing heat from both poles – indicating that it has the long-term stability required for life to develop. The findings have been published today (7 November) in Science Advances.
