When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ...
Like a supersonic jet being blasted with high-speed winds, Earth is constantly being bombarded by a stream of charged particles from the sun known as solar wind.
In a paper, titled "Partial coherence enhances parallelized photonic computing," published in Nature, researchers from the University of Oxford, along with collaborators from the Universities of Muenster, Heidelberg, and ...
A pair of astrophysicists from Ciudad Universitaria and Universidad Complutense de Madrid, both in Spain, report evidence that comet A117uUD was put on its current "hyperbolic trajectory" when it passed close to Saturn two ...
Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun's harsh ultraviolet rays. But closer to the ground, ozone ...
Rocks recently exposed to the sky after being covered with prehistoric ice show that tropical glaciers have shrunk to their smallest size in more than 11,700 years, revealing the tropics have already warmed past limits last ...
Astronomers have recently found hundreds of "polluted" white dwarf stars in our home galaxy, the Milky Way. These are white dwarfs caught actively consuming planets in their orbit. They are a valuable resource for studying ...
The stars aren't fixed and unchanging, unlike what many ancient people thought. Once in a while, a star appears where there wasn't one before, and then it fades away in a matter of days or weeks.
Multitasking robots collaborate with humans in large warehouses, and chatbots respond to queries on banking websites. Artificial intelligence assistants even sort documents for law firms. William & Mary Assistant Professor ...
Interest in interstellar objects (ISOs) was ignited in 2017 when 'Oumuamua flew through our solar system and made a flyby of Earth. Roughly two years later, another ISO passed through our solar system—the interstellar comet ...
