Terahertz radiation—the band of the electromagnetic spectrum between microwaves and visible light—has promising applications in medical and industrial imaging and chemical detection, among other uses.
Proxima b, an Earth-size planet right outside our solar system in the habitable zone of its star, may not be able to keep a grip on its atmosphere, leaving the surface exposed to harmful stellar radiation and reducing its ...
Imagine a planet like Jupiter zipping around its host star every day and a half, superheated to temperatures hotter than most stars and sporting a giant, glowing gas tail like a comet.
Astronomers have developed a way to detect the ultraviolet (UV) background of the Universe, which could help explain why there are so few small galaxies in the cosmos.
A new computer simulation helps explain the existence of puzzling supermassive black holes observed in the early universe. The simulation is based on a computer code used to understand the coupling of radiation and certain ...
Explaining a 'once-in-a-billion-year event': A perfect storm of fire and ice may have led to snowball Earth
What caused the largest glaciation event in Earth's history, known as 'snowball Earth'?Geologists and climate scientists have been searching for the answer for years but the root cause of the phenomenon remains elusive.
Ultrashort bursts of electrons have several important applications in scientific imaging, but producing them has typically required a costly, power-hungry apparatus about the size of a car.
In a new study, researchers measure the spin properties of electronic states produced in singlet fission – a process which could have a central role in the future development of solar cells.
