Colliding with Jupiter

WILLIAM GAO

The Shoemaker–Levy 9 collision with Jupiter was the first direct observation of an extraterrestrial collision of Solar System objects. Shoemaker–Levy 9 disintegrated in to 21 fragments during a close encounter with Jupiter in July 1992 and finally collided with Jupiter two years later in July 1994.

The remarkable collision lasted a week and left large, murky marks on Jupiter’s southern hemisphere that took weeks to dissipate. With some individual fragments as large as 2 km in diameter, Shoemaker–Levy 9 would have been catastrophic to Human civilization but might not be enough to cause mass extinction on Earth, such as the 10 km wide asteroid that triggered the Cretaceous–Paleogene extinction event 66 million years ago.

New radio carbon dating technique will revolutionise field archaeology

#WNITU

Scientists from the University of Liverpool are developing a new carbon dating technology that could revolutionize field archaeology.

In partnership with Norton Priory Museum & Gardens and supported by funding from the Arts Council England, they will develop a new technique which will make it quicker and easier to date archaeological finds.
