Martian Meteorite

A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020, 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. The largest complete, uncut Martian meteorite, Taoudenni 002, was recovered in Mali in early 2021. It weighs 14.5 kilograms (32 pounds) and is on display at the Maine Mineral & Gem Museum. There are three groups of Martian meteorite: shergottites, nakhlites and chassignites, collectively known as SNC meteorites. Several other Martian meteorites are ungrouped. These meteorites are interpreted as Martian because they have elemental and isotopic compositions that are similar to rocks and atmospheric gases on Mars, which have been measured by orbiting spacecraft, surface landers and rovers. The term does not include meteorites found on Mars, such as Heat Shield Rock.

Chilean Blob

Chilean Blob The Chilean Blob was a large mass of tissue found on Pinuno Beach in Los Muermos, Chile in July 2003. It weighed 13 tonnes (14 tons) and measured 12 metres (39 ft) across. The Chilean Blob made headlines around the world because biologists were initially unable to identify it, and were speculating that it was the remains of some species of giant octopus previously unknown to science. In June 2004, DNA found in the blob was found to match that of a sperm whale: the blob was a large mass of adipose tissue, the partial remains of a dead sperm whale.

Lake Retba

Lake Retba Lac Rose (meaning Pink Lake) lies north of the Cap Vert peninsula of Senegal, some 30 km (18 miles) north-east of the capital, Dakar, in northwest Africa. It is named for its pink waters caused by Dunaliella salina algae and is known for its high salt content, up to 40% in some areas.

Lakes In Badain Jaran Desert

Lakes In Badain Jaran Desert A desert oasis is usually a sight to behold, providing a welcome respite from the apparently unending stretch of brown sand. The Badain Jaran Desert, which stretches from Mongolia to China, contains a total of 140 permanent lakes dotting its dry landscape. The lakes, which are located between sand dunes, are said to have originated from subsurface springs fed by precipitation from the nearby mountain's snowy peaks, despite the fact that these ranges are hundreds of kilometers distant.
