In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to offer: with further analyses, the MAGIC scientists could now confirm that the speed of light is constant in vacuum - and not dependent on energy. So, like many other tests, GRB data also corroborate Einstein's theory of General Relativity. The study has now been published in Physical Review Letters.
The analysis of Tropical Cyclone Cristina's cloud top temperatures revealed some bands of thunderstorms were developing and wrapping around the center of the storm's circulation.
Using Kyoto University's new 3.8M Seimei Telescope, in collaboration with the National Astronomical Observatory of Japan, astronomers succeeded in detecting 12 stellar flare phenomena on AD Leonis. One of these flares was 20 times larger than those emitted by our own sun, categorizing it a 'superflare'. Subsequent data analysis presents new insight into these explosive phenomena.
The lightning data can serve as an indicator for hazardous weather phenomena and improve short-term forecasting,
When NASA's Aqua satellite passed over Tropical Storm Cristina in the Eastern Pacific Ocean on July 8, it gathered water vapor data that provided information about the intensity of the storm.
The National Science Foundation's Arecibo Observatory in Puerto Rico has proven itself instrumental in another major astronomical discovery. An international team of scientists, led by the University of East Anglia in the United Kingdom, found an asymmetrical double neutron star system using the facility's powerful radio telescope.
Researchers have discovered an unusual pulsar - one of deep space's magnetized spinning neutron-star 'lighthouses' that emits highly focused radio waves from its magnetic poles. It is unusual because the masses of its two neutron stars are quite different -- with one far larger than the other. The breakthrough provides clues about unsolved mysteries in astrophysics -- including the expansion rate of the Universe (the Hubble constant). The discovery was made using the Arecibo radio telescope, Puerto Rico.
Northwestern University researchers have synthesized a new form of melanin enriched with selenium. Called selenomelanin, this new biomaterial shows extraordinary promise as a shield for human tissue against harmful radiation.
According to the United Nations, about one-fifth of the world's population lives in areas where water is scarce. Therefore, technologies to produce clean water from undrinkable sources, such as seawater, river or lake water, and contaminated water, are urgently needed. Now, researchers reporting in Nano Letters have developed a wood-based steam generator that, with the help of bacterial-produced nanomaterials, harnesses solar energy to purify water.
Researchers at the US Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) have developed a novel machine learning approach to quickly enhance the resolution of wind velocity data by 50 times and solar irradiance data by 25 times--an enhancement that has never been achieved before with climate data.
