Specimens of the black coral genus Leiopathes, such as Leiopathes glaberrima, are among the oldest continuously living organisms on the planet: around 4,265 years old. [67] Giant barrel sponges can live more than 2,000 years.
ALH84001 is thought to be one of the oldest Martian meteorites, proposed to have crystallized from molten rock 4.091 billion years ago. [5] Chemical analysis suggests that it originated on Mars [6] [7] when there was liquid water on the planet's surface. [8] [9]
Mars-1 was the first spacecraft launched to Mars in 1962, [266] but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971–1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of ...

Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates. [1]The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia.

<p>You've probably never heard of a long-extinct organism known as Dickinsonia. Unlike dinosaurs like the Tyrannosaurus rex or more recent extinct beasts like the wooly mammoth, fossils of ...
A recent study of gelatinous marine creatures revealed a curious ability in which two animals fuse and function as a single organism. The comb jelly, one of the oldest animals on Earth, can fuse ...
Formation of a greenstone belt of the Acasta Gneiss of the Slave craton in northwest Canada - the oldest known rock belt. [28] 3900–2500 Ma Cells resembling prokaryotes appear. [29] These first organisms are believed to have been chemoautotrophs, using carbon dioxide as a carbon source and oxidizing inorganic materials to extract energy. 3800 Ma
