Space Dust

Stuff is constantly falling down on the Earth from outside its atmosphere. This might be very large rocks that we will notice to specks of dust that fall and float down. Currently, estimates of the Earth’s intake of space dust vary from around five tons to as much as 300 tons every day. The Cosmic Dust in the Terrestrial Atmosphere (CODITA) project will investigate what happens to the dust from its origin in the outer solar system all the way to the earth’s surface. The work, funded by the European Research Council, will also explore whether cosmic dust has a role in the Earth’s climate and how it interacts with the ozone layer in the stratosphere.
