The aurora is among nature's most visually striking phenomena. It occurs when charged particles from the sun are funneled by Earth's magnetic field into the upper atmosphere, where they collide with atoms and molecules and produce distinctly colored curtainlike patterns of light.

Earth's core may have been leaking hydrogen for billions of years

When Earth formed billions of years ago, its metallic core was wrapped in a global ocean of molten rock, which eventually cooled and crystallized to form the mantle. Today, when deep-rooted mantle plumes rise toward the surface and produce volcanic eruptions, the resulting lava c

Webb reveals metal-rich gas around Milky Way's central black hole

The gas orbiting Sagittarius A (Sgr A*), the supermassive black hole at the center of the Milky Way galaxy, is rich in metals, researchers at McGill University's Trottier Space Institute have found. The metal enrichment probably resulted from stars that exploded and released mate
