A new family of extraterrestrial particles, probably of cometary origin, has been identified for the first time in snow in Central Antarctica. The micrometeorites, which are remarkably well preserved, are made up of organic matter containing small assemblages of minerals from the coldest and most remote regions of the solar system.
