The gently curved horizon of Earth emits a faint glow, with a dense blanket of stars in view above it. This long-exposure photograph taken from the International Space Station reveals a colorful atmospheric glow crowning Earth's horizon, back-dropped by the dazzling Milky Way.

Over the last 20 years, the search for planets orbiting other stars has reached fever pitch.

We have discovered more than 2,000 extra-solar planets to date, and that number continues to grow. Using expertise in star-dating to measure the ages of thousands of stars and planets in the Milky Way, Museum Curator Ruth Angus describes how these planets are detected and what we now understand about the diverse planetary ecosystems in the Milky Way. Find out how she hopes to reveal the processes behind the formation of these alien worlds and their distribution across the galaxy.
