When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The ...
Astronomers have employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe a subdwarf star designated TIC 441725813. In result, they found that TIC 441725813 is a hybrid hot B subdwarf pulsator. The discovery ...
NASA's DART mission—Double Asteroid Redirection Test—was humanity's first real-world planetary defense mission.
When the expanded yellow tentacles of the sun coral began to appear on the Brazilian coastline, alarms rang. This species, also known as Tubastraea, was not supposed to be there. The movement of oil platforms and other shipping ...
A collaboration between researchers at the Laboratory of Medical Sciences (LMS) in London and the Laboratory of Molecular Biology (LMB) in Cambridge, has solved a decades-old mystery which could pave the way to better cancer ...
Scientific studies have filled the pages of AGU journals for more than a century. These articles reveal how the study of geophysics has evolved alongside technology and societal interests and they tell the story of our expanding ...
A surprising discovery about the evolution of our galaxy using data from the Gaia mission found a large number of ancient stars on orbits similar to that of our sun. They formed the Milky Way's thin disk less than 1 billion ...
Scientists have determined that a rare element found in some of the oldest solids in the solar system, such as meteorites, and previously thought to have been forged in supernova explosions, actually predate such cosmic events, ...
Our solar system is our immediate cosmic neighborhood. We know it well: the sun at the center; then the rocky planets Mercury, Venus, Earth, and Mars; and then the asteroid belt; followed by the gas giants Jupiter and Saturn; ...
The sun rotates the fastest at the equator, whereas the rotation rate slows down at higher latitudes and is the slowest at the polar regions. But a nearby sun-like star—V889 Herculis, some 115 light years away in the constellation ...
