‘Crash Clock’ reveals how soon satellite collisions would occur after a severe solar storm — and it’s pretty scary

Artist’s illustration of space junk orbiting Earth. (Image credit: NASA) How long would it take for satellites to begin to collide with space junk and each other if they were to suddenly lose their ability to avoid each other? A new study finds that, with the immense quantity of satellites that hurtle in Earth’s orbit

Solar, onshore wind and gas backup is (still) the cheapest way to power Australia: new report

Solar, onshore wind and gas backup is (still) the cheapest way to power Australia: new report

What’s the cheapest way to power Australia? Every year, CSIRO researchers and modellers seek to answer this very large question in their GenCost report. On one level, the answer in the draft 2025–26 report is unsurprising: solar and wind are the cheapest form of generation. However, this report has gone further by modelling the cheapest
