The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid. Whether the approach could save Earth from a future threat remains to be seen.

Refining current opacity models will be key to unearthing details of exoplanet properties — and signs of life — in data from the powerful new telescope.

Satellite telemetry, tiny geolocation tags and passive acoustic recording are providing new insights into bird migration and vital data for conservation.

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.

Cheap and quick to produce, these digitally manufactured plasma sensors could help scientists predict the weather or study climate change.

Build a powerful enough laser, and you can shine it into space. Aim it well, and you can blind satellites.

The southern hemisphere is more likely to be hit by space debris than the northern one.

With decades of images and data from the same locations, these satellites can show changes over time, including deforestation, changes in waterways and how loss of trees corresponds to urban heat.

They’re crucial for tracking deforestation, pinpointing dangerous heat, and helping people respond to fires, floods and insidious risks that might not be obvious from the ground.

The Met Office issued its heatwave warning six days before the mercury peaked – potentially saving many lives.
