Meteor impacts are an inevitable part of being a rocky planet in space. The craters they leave behind are a window into the tumultuous history of Earth.
From space to the outback, meteorite-tracking tools are building the knowledge we need to prepare for a future asteroid impact.
This is an enhanced satellite image of Western Australia’s Great Sandy Desert. Yellow sand dunes cover the upper right, red splotches indicate burned areas, and other colours show different types of surface geology.

Private satellite companies have boomed in recent years, and many experts have wondered what role they would play in a conflict. They have proved to be invaluable to Ukraine in recent months.
Scientists are building a pollen forecasting model using meteorology, botany, pollen count numbers and satellite imagery to help people plan ahead.
Modern computing allows to spot isolated trees and shrubs in semi-arid areas, facilitating research on the evolution of vegetation cover.

Advanced techniques allowed our research team to build an open database of billions of individual trees and challenge some common perceptions about vegetation in arid and semi-arid zones.
We used satellite images to study the life cycles of mangrove forests in the Northern Territory, Queensland, and New South Wales — and found a surprising degree of variation.
