Impact glasses from Belize represent tektites from the Pleistocene Pantasma impact crater in Nicaragua. [PDF]
Commun Earth Environ, 2021 Tektites are terrestrial impact-generated glasses that are ejected long distance (up to 11,000 km), share unique characteristics and have a poorly understood formation process. Only four tektite strewn-fields are known, and three of them are sourced from

Probing the hydrothermal system of the Chicxulub impact crater. [PDF]
Sci Adv, 2020 The Chicxulub impact event generated a long-duration hydrothermal system suitable for microbial life. The ~180-km-diameter Chicxulub peak-ring crater and ~240-km multiring basin, produced by the impact that terminated the Cretaceous, is the largest ...

Lunar impact crater identification and age estimation with Chang'E data by deep and transfer learning. [PDF]
Nat Commun, 2020 Impact craters, which can be considered the lunar equivalent of fossils, are the most dominant lunar surface features and record the history of the Solar System. We address the problem of automatic crater detection and age estimation.

On the detection of the Wilkes Land impact crater
Earth, Planets and Space, 2018 The definitive existence of a giant impact crater, two times larger than the Chixulub crater in the Yucatan peninsula, from an extraterrestrial origin, 1.6 km beneath Wilkes Land, East Antarctica, remain controversial.
