Methane is a potent greenhouse gas that can leak from oil and gas wells, pipelines and landfills. Satellites can spot the releases fast enough to get them fixed and help protect the climate.
Space exploration is not a waste of resources, but a source of technological and medical advances, a tool for climate monitoring and a source of educational inspiration for youth.
The sky is becoming more cluttered with satellites and space junk. This is affecting astronomical study, but will only have a minor effect — if any — on the viewing of the solar eclipse.
Powerful jets are launched from the most massive objects in our universe, but we don’t fully understand how. This measurement gets us a step closer to solving the mystery.

Satellite photography of the Ukrainian city of Bakhmut shows block after block of destroyed buildings. Satellite radar provides a different view – a systematic look at the destruction of the whole city.
Russia isn’t likely to put nuclear missiles in space, but their reported anti-satellite weapon is just as alarming. An expert on nuclear strategy explains.
Despite what you may think, Australia has a long history of space activities. But this is the first time the Australian public has been asked its opinions on space.

Countries have submitted applications for hundreds of thousands of new satellites to be launched. The scale poses challenges for overcrowding orbit, with environmental and safety challenges.
Earth’s orbits are getting more and more crowded. To keep track of everything and avoid collisions and catastrophes, we need a new field: space domain awareness.
The combination of data and maps is useful for a lot more than just helping you get from point A to point B. Think natural disasters, global supply chains and climate change.
