1250 Galanthus 1250 Galanthus 1250 Galanthus, provisional designation , is a dark background asteroid from the central regions of the asteroid belt, approximately 20 kilometers in diameter. It was discovered on 25 January 1933, by German astronomer Karl Reinmuth at the Heidelberg Observatory. The asteroid was named for the herbaceous plant "Galanthus", also known as "snowdrop". "Galanthus" is a non-family asteroid from the main belt's background population. It orbits the Sun in the central main-belt at a distance of 1.9–3.2 AU once every 4 years and 1 month (1,488 days; semi-major axis of 2.55 AU). Its orbit has an eccentricity of 0.27
Chlamydomonas nivalis Chlamydomonas nivalis Chlamydomonas nivalis is a unicellular red-coloured photosynthetic green alga that is found in the snowfields of the alps and polar regions all over the world. They are one of the main algae responsible for causing the phenomenon of watermelon snow, where patches of snow appear red or pink and emit a ripe watermelon odour upon disturbance. The first account of microbial communities that form red snow was made by Aristotle. Researchers have been active in studying this organism for over 100 years. Although "C. nivalis" is closely related to "Chlamydomonas reinhardtii", the environmental conditions each species inhabits are
