Green fireball streak lights up Pacific Northwest as other meteors dazzle across the U.S.

A bright green fireball was captured on a dashcam over southwestern Washington near Portland, lighting up the dawn sky as a meteor seen across the Pacific Northwest. The green color is typically from magnesium (nickel can contribute), and NASA notes related fireball sightings across multiple states and Ontario, with a larger Ohio meteor fragmenting and possibly reaching the ground. With more dashboard and doorbell cameras, scientists may deduce trajectory, though ground hits from fireballs are rare.

Australia witnesses rare green fireball meteor explosion.

A rare green meteor, known as a bolide, exploded over Australia, creating a bright flash of light and a loud bang that could be seen and heard for hundreds of miles. The meteor was likely small, between 1.6 and 3.2 feet across, and could have been traveling up to 93,000 mph. Bolides are meteors that blow up in Earth's atmosphere due to a buildup of friction that eventually causes the space rocks to instantaneously shatter with enough force to trigger a sonic boom. The unusual green flash of the meteor was caused by a high concentration of metals such as iron and nickel in the meteor.
