As war begins between Ukraine and Russia, a range of stories provides context to help readers understand the conflict.
With an antenna, a laptop and some software, you can take a picture of Earth from space.
Glaciers in North America, Europe and the Andes, in particular, have significantly less ice than people realized.
A phenomenon first theorized over 200 years ago is also a telltale sign of nuclear tests.
The nanosatellite constellation will detect, monitor and identify foreign vessels within the country’s maritime borders.
Megaconstellations of satellites will visually clutter the night sky, disrupting astronomical research. And the environmental damage caused by these satellites is still unknown.
Australia’s bushfire response relies on foreign satellites, which are not designed to assess our highly flammable eucalypt-clad landscapes.
Activities in space today are far more numerous and complicated compared to 1967, before humans had landed on the moon or Elon Musk had been born. Two experts explain the need for better laws to keep space peaceful.
Russia’s testing of an anti-satellite weapon risked the life of astronauts on the International Space Station and could have astronomical impacts on Earth.
A Russian satellite has been destroyed in a missile strike, creating a vast amount of debris that joins the tens of thousands of pieces already in orbit around the Earth.
Russia destroyed one of its old satellites during a successful test of an anti-satellite weapon. A space security expert explains what this weapon was and the dangers of the expanding debris field.
International space law doesn’t explicitly prohibit anti-satellite missile tests — which makes uproar over Russia’s actions all the more significant.

Satellite imagery can help to get data in fragile, crisis-affected situations.
New technologies can help reduce the cost of producing maps that warn where floods might happen.
The CUAVA-1 cubesat will monitor space weather and changes to Earth’s ionosphere that affect satellites and electronics.
Did we observe the most distant gamma ray burst yet seen, or was it something closer to home?
What did Mercury look like as BepiColombo swung by?
In the past decade, the number of satellites in orbit has skyrocketed thanks to tiny electronics and cheap launches. The crowded night sky is posing problems for astronomers and astronauts.
