The researchers said they believe the liquid carbon rocketed skyward and formed tiny airborne beads that blanketed the planet. The team of U.S., U.K., Italian and New Zealand researchers said those beads, known as carbon cenospheres, cannot be formed through plant matter combustion... The carbon cenospheres were deposited next to a thin layer of the element iridium — an element more likely to be found in solar system asteroids than on Earth. The iridium-laden dust is believed to be the shattered remains of the approximately 125-mile-wide asteroid’s impact.
