A geode (/ ˈ dʒ iː. oʊ d /; from Ancient Greek γεώδης (geṓdēs) ' earthlike ') is a geological secondary formation within sedimentary and volcanic rocks. Geodes are hollow, vaguely spherical rocks, in which masses of mineral matter (which may include crystals) are secluded.
For example, the first evidence of knowledge of the spherical shape of Earth in Scandinavia is a 12th-century Old Icelandic translation of Elucidarius. [78] A list of more than a hundred Latin and vernacular writers from Late Antiquity and the Middle Ages who were aware that Earth was spherical has been compiled by Reinhard Krüger, professor ...
Coso artifact in 2018. The Coso artifact is an object falsely claimed by its discoverers to be a spark plug encased in a geode.Discovered on February 13, 1961, by Wallace Lane, Virginia Maxey, and Mike Mikesell while they were prospecting for geodes near the town of Olancha, California, it has long been claimed as an example of an out-of-place artifact.

It's also more evidence that life could arise on the dwarf planet Ceres and Saturn's moon Enceladus. NASA probed an asteroid and found an ancient repository of ingredients for life.
The fascinating results shed light on the origins of life. Other worlds Researchers identified sodium salts, such as the needles of hydrated sodium carbonate highlighted in purple in this false ...
Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that ...
Instead, researchers might find indirect evidence, such as climate changes, anomalies in sediment, or traces of nuclear waste. The hypothesis also speculates that artifacts from past civilizations could be found on the Moon and Mars, where erosion and tectonic activity are less likely to erase evidence. The concept of pre-human civilizations ...
Case in point: a new study led by the National Research Council of Italy discovered evidence of life in a perennially frozen lake in the Antarctic. This is particularly perplexing because this ...
