A team of geologists from Curtin University has discovered unequivocal evidence for a hypervelocity meteorite impact 3.47 billion years ago (Archean Eon) in the center of the Pilbara region in Western Australia. Before this discovery, the oldest impact crater was 2.2 billion years old, so this is by far the oldest known crater ever found on Earth.

The Sun as seen by Solar Orbiter in extreme ultraviolet light from a distance of roughly 75 million km. The image is a mosaic of 25 individual images taken on March 7, 2022 by the high resolution telescope of the Extreme Ultraviolet Imager (EUI) instrument. Taken at a wavelength of 17 nanometers, in the extreme ultraviolet region of the electromagnetic spectrum, this image reveals the Sun’s upper atmosphere, the corona, which has a temperature of around a million degrees Celsius.
