The Space Lab competition from YouTube invited young scientists to submit an experiment for the chance to have it performed by NASA aboard the International Space Station.
From among thousands of entrants, six regional winners have been chosen. In North America, Emerald Bresnahan of Plainville, Massachusetts, was chosen for her Snowflakes in Space experiment.
Emerald suggests that galaxies might form in a similar way to snowflakes. She wants to test how snowflakes form in the absence of gravity to better understand the link between them and other complex shapes like galaxies. Will these tiny structures give us the answers to some of our biggest questions about the Universe?
