Como vales gigantescos se formaram na Lua em poucos minutos?

Pesquisadores analisaram cânions lunares usando mapeamento fotogeológico e depósitos de material ejetado por impactos.

O impacto de asteroides ou cometas perto do polo sul lunar criou os cânions em menos de dez minutos, com fluxo rápido de detritos e intensa liberação de energia.

A energia liberada foi: 1.200 a 2.200 vezes maior que a de uma explosão nuclear planejada para um segundo Canal do Panamá e 130 vezes maior que o inventário global de armas nucleares

Os cânions foram nomeados pelos cientistas:

Um deles se chama Vallis Schrödinger: 270 km de comprimento, 20 km de largura e 2,7 km de profundidade, com 15 crateras secundárias identificadas.

Outro se chama Vallis Planck: 280 km de comprimento, 27 km de largura e 3,5 km de profundidade, com crateras secundárias espalhadas por 860 km.

Essas descobertas ajudam a entender a formação da superfície lunar e os efeitos de impactos cósmicos extremos no passado do Sistema Solar.
