Hot stuff from cold space

Researchers have made their first finds of a recent NASA probe into space to collect particles from comet that recently swung through our solar system.

And they're surprised to find that some of the comet particles are mineral fragments that were composed at high temperatures. It's believed that the particles could only be formed in the nebulae surrounding early-stage stars. So that means the particles were either made by our sun and then ejected into the farthest reaches of our solar system, or they came from star systems in other parts of the galaxy.

The particles were collected with aerogel, the lightest solid material on earth. Aerogel is one of the materials currently being featured in the Strange Matter exhibit at the Science Museum of Minnesota.
