The Vredefort impact structure is the largest verified impact structure on Earth. [1] The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed.
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
The smallest craters found have been microscopic in size, found in rocks returned to Earth from the Moon. The largest crater called such is about 290 km (180 mi) across in diameter, located near the lunar south pole.
Scientists believe they’ve discovered what time and erosion have concealed.
Stunning drone footage has revealed details of the Batagaika crater, a one kilometre long gash in Russia's Far East that forms the world's biggest permafrost crater. In the video two explorers ...
Scientists expected the James Webb Space Telescope to reveal unknowns in the deepest realms of space.But they certainly didn't anticipate this. While scanning a region of the cosmos near the Big ...
2002 MS 4 was discovered on 18 June 2002 by astronomers Chad Trujillo and Michael Brown at Palomar Observatory in San Diego County, California, United States. [1] The discovery formed part their Caltech Wide Area Sky Survey for bright, Pluto-sized Kuiper belt objects using the observatory's 1.22-meter (48 in) Samuel Oschin telescope with its wide-field CCD camera, which was operated jointly ...
In Jack Williamson's 2001 novel Terraforming Earth, the crater is utilized for "Tycho Base", a self-sustaining, robot-controlled installation aimed at restoring life to the (dead) planet Earth after an asteroid sterilizes the biosphere. In the 2019 film Ad Astra, the Moon base is situated in the Tycho crater. This is Roy's first stop on his ...
