In August of 2017, millions peered through protective eyewear at the solar eclipse -- the first total eclipse visible in the continental United States in nearly 40 years. During the event, researchers from the Cornell Lab of Ornithology and the University of Oxford watched radar to observe the behavior of birds and insects.
The symmetries that govern the world of elementary particles at the most elementary level could be radically different from what has so far been thought. This surprising conclusion emerges from new work published by theoreticians from Warsaw and Potsdam. The scheme they posit unifies all the forces of nature in a way that is consistent with existing observations and anticipates the existence of new particles with unusual properties, which may even be present in our close environs.
Astronomers may have finally found a doomed star that seemed to have avoided detection before its explosive death.
A close study of auroras has revealed new ways of understanding the physics of explosive energy releases in space, according to new UCL-led research.
An international team of astronomers has discovered the nearest single star to the sun hosts an exoplanet at least 3.2 times as massive as Earth -- a so-called super-Earth. Data from a worldwide array of telescopes, including Keck Observatory in Hawaii, have revealed this frozen, dimly lit world. The newly discovered planet is the second closest known exoplanet to Earth and orbits the fastest moving star in the night sky.
When rains fell on the arid Atacama Desert, it was reasonable to expect floral blooms to follow. Instead, the water brought death. An international team of planetary astrobiologists has found that after encountering never-before-seen rainfall three years ago at the arid core of Peru's Atacama Desert, the heavy precipitation wiped out most of the microbes that had lived there.
Large quantities dust from the deserts of the Middle East can settle on the Tibetan Plateau, darkening the region's snowpack and accelerating snow melt. A new atmospheric modeling study suggests that, in some years, heavy springtime dust deposition can set off a series of feedbacks that intensify the Indian summer monsoon. The findings could explain a correlation between Tibetan snowpack and the Indian monsoon first observed by British meteorologist Henry Blanford in 1884.
Tropical Cyclone Gaja continued to track toward a landfall in southeastern India when NASA-NOAA's Suomi NPP satellite flew over the Bay of Bengal and provided a visible image of the storm.
For the first time astronomers have detected gravitational waves from a merged, hyper-massive neutron star. The scientists, Maurice van Putten of Sejong University in South Korea, and Massimo della Valle of the Osservatorio Astronomico de Capodimonte in Italy, publish their results in Monthly Notices of the Royal Astronomical Society: Letters.
In 2011, researchers proposed that artificial guide stars could be used to measure the Earth's magnetic field in the mesosphere. An international group of scientists has recently managed to do this with a high degree of precision. The technique may also help to identify magnetic structures in the solid Earth's lithosphere, to monitor space weather, and to measure electrical currents in the part of the atmosphere called ionosphere.
