A massive 500,000-mile-wide (800,000-kilometer) coronal hole in the sun's atmosphere is unleashing a stream of fast-moving solar wind toward Earth, potentially supercharging auroras on Jan. 31 and ...

Auroras occur when solar wind interacts with Earth's magnetic field.The charged particles from the sun collide with gases in the upper atmosphere, such as oxygen and nitrogen, transferring energy ...

Feb. 3, 2025 — A recent study has uncovered compelling evidence suggesting that the climate effects of new particles in urban areas have been significantly ...

The Earth's atmosphere has strengthened its ability to remove air pollutants, including the potent climate-warming gas methane, according to research published in Nature Communications.

Climate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or surface changed, or when the Sun’s energy varied. But in the past century, ...

This encompasses the interactions between various parts of the atmosphere as well as interactions with the oceans and freshwater systems, the biosphere and human activities. The recent ...
