When a meteoroid survives its trip through the atmosphere and hits the ground, it’s called a meteorite. Meteorites typically range between the size of a pebble and a fist. Most space rocks smaller than a football field will break apart in Earth’s atmosphere.

Finding meteorites is not an easy task. There is a network of high-quality ground-based sensors called the Global Fireball Observatory, but it only covers about 1% of the planet. The US satellite data published by NASA covers a much larger area than ground-based detectors, but it only picks up the biggest fireballs. What's more, they don't always g...
In 2019, Australia's Bureau of Meteorology started making its weather radar data openly availableto researchers and the public. I saw this as an opportunity to complete the puzzle. I combed through the record of events from the Desert Fireball Network and NASA, and cross-matched them with nearby weather radars. Then I looked for unusual radar signa...
I gave what I hoped was an accurate treasure map to my colleague Andy Tomkins from Monash University. In September this year, he happened to be driving past the site on his way back from an expedition in the Nullarbor. Thankfully, Andy found the first meteorite within 10 minutes of looking. In the following two hours, his team found nine more. The ...
This find was only made possible by the free availability of crucial data—and the people who made it available. The US satellites that detected the fireball are presumably there to detect missile and rocket launches. However, somebody (I don't know who) must have figured out how to publish some of the satellite datawithout giving away too much abou...
O que são meteoróides? De acordo com a explicação da Nasa (a agência espacial norte-americana), os meteoróides são rochas que ainda estão no espaço. Eles variam em tamanho, e podem ir desde grãos de poeira até pequenos asteroides.
