This piece of interplanetary dust is thought to be part of the early solar system and was found in our atmosphere, demonstrating lightweight particles could survive atmospheric entry as they do ...

I work with Mihaly Horányi studying the interplanetary dust environment with instrumentation and simulation. I'm the lead for the Student Dust Counter aboard New Horizons currently making in-situ ...

Making amino acids is tricky, even in the laboratory. We know amino acids exist in some kinds of meteorites and interplanetary dust particles. When they rain down on a planet's surface ...

Material that is ejected from comets reflects light, giving them their characteristic dust tails. This material is spread throughout the solar system and makes up the interplanetary dust enviroment.
