Tracing interstellar dust back to the solar system's formation
Interplanetary particles from Earth's upper atmosphere contain dust from the initial formation of the solar system. The exotic grains may represent the building blocks of planets from 4.6 billion years ago. Analysis of these materials makes it possible to gain deeper insights into the processes that formed and altered our solar system.

Gas 'waterfalls' reveal infant planets around young star
The birthplaces of planets are disks made out of gas and dust. Astronomers study these so-called protoplanetary disks to understand the processes of planet formation. Beautiful images of these disks show distinct gaps and ring features in dust, which may be caused by infant planets.
