Dust grains could be remnants of stellar explosions billions of years ago

Microscopic dust particles have been found in meteoritic material on Earth, particles that were likely formed in stellar explosions that occurred long before the creation of our star, the sun. Whether some of these particles of stardust, known as ‘pre-solar grains,’ came from classical nova explosions is the focus of ongoing experimental nuclear physics research.
