]]> Every year, roughly 10 particles of space dust land on each square meter of Earth’s surface. “That means that they are everywhere. They are on the streets. They are in your home. You may even have some cosmic dust on your clothes,” said Matthew Genge, a planetary scientist at Imperial College London who specializes in these alien dust grains, known as micrometeorites. Round and multicolored like...

]]> Meenakshi Wadhwa is the first to say she is lucky to be alive. On August 2, 2017, Wadhwa and colleagues were prospecting for volcanic rocks in the cooled lava fields of Iceland. After collecting some samples of basaltic rock, which they hoped to use as a proxy for Martian rocks, the team hopped in their vehicles to drive back to their lodgings. Wadhwa sat in the back seat of one of the SUVs...

Additional tests revealed that the rock is the...
