Scientists discover snow on Mars and reveal results in new study

Scientists have discovered snow on Mars according to a new study; the snowflakes seen on Mars are roughly the size of a human red blood cell. The study information will be published in the Journal of Geophysical Research.

The snow is considerably smaller than the snow seen on Earth and it is comprised of carbon dioxide instead of water.

Researchers were reviewing video recorded by two spacecraft on the Red Planet that was taken in 2007 to 2008 when they discovered it.

Co-author of the study, Kerri Cahoy of Massachusetts Institute of Technology (MIT) said: "These are very fine particles, not big flakes." An astronaut standing on Mars "would probably see it as a fog, because they’re so small."
