Life on Mars. August 6, 1996.

In August 6, 1996 a team of researchers announced that the meteorite ALH84001, discovered in the Allan Hills of Antarctica, may contain evidence of life on Mars, but further tests were inconclusive. To date, no proof has been found of past or present life on Mars. Cumulative evidence shows that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms. The existence of habitable conditions does not necessarily indicate the presence of life. Scientific searches for evidence of life began in the 19th century, and continue today via telescopic investigations and deployed probes. While early work focused on phenomenology and bordered on fantasy, the modern scientific inquiry has emphasized the search for water, chem...

First evidence of HMS Erebus found. August 15, 1855.

The search by Europeans for a western shortcut by sea from Europe to Asia began with the voyages of Christopher Columbus in 1492 and continued through the mid-19th century with a long series of exploratory expeditions originating mainly in England. These voyages, when to any degree successful, added to the sum of European geographic knowledge about the Western Hemisphere, particularly North America, and as that knowledge grew larger, attention gradually turned toward the Arctic. By 1800, the discoveries had already showed conclusively that no Northwest Passage navigable by ships lay in the temperate latitudes between the Pacific and the Atlantic Oceans. In 1804, Sir John Barrow became Second Secretary of the Admiralty, a post he held until 1845, and began a push by the Royal Navy to comple...
