Weatherday: Stardust

That cold overnight has left frosty conditions and possible icy patches on roads. Early cloud will bring occasional showers, some wintry.

But it will clear for the afternoon, with good sunny spells and a clear night with further below-freezing conditions. Highest temperature 3deg in light northwesterly breeze.

On this day in 2004, dust was collected from the comet Wild 2 by a NASA spacecraft. The material was later found to include glycine, an amino acid essential for the formation of life.
