Astronomers know that simple organic molecules can be found in planets, comets and interstellar dust clouds.

The interstellar dust cloud that became the solar system was rich in radioactive material, including uranium, the fuel for nuclear reactors.

His research involves the study of the interstellar medium, especially interstellar dust, photodissociation regions, and shock waves.

To analyze the aerogel for interstellar dust, one million photographs will be needed to image the entirety of the sampled grains.

These stars are thought to be significant contributors to interstellar dust.
