Around 20 years ago NASA launched a spacecraft to study the comet Wild-2. What it brought back would cause scientists to wonder whether the building blocks of life could have arrived at Earth on a comet.

Aerogel has extraordinary properties but it can be tough to work with. This video looks at modifying aerogels to take advantage of their unique characteristics.

Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels,...

We put aerogel to the test vs 'not-a-flamethrower', a huge 2000°C flame to a large fiberglass blanket infused with silica aerogel - formerly the lightest solid (that title is now held by graphene aerogel).

Researchers from the National University of Singapore have found a way to convert plastic bottles into an ultralight super material with various applications.
