Understanding the stars that produce some of that space dust has been tickling those impertinent minds for decades. And to bring that dust back to earth laboratories, NASA’s Stardust mission just traveled seven years and 2.88 billion miles.
It is for 35 years, Lee Anne Willson, a University Professor of physics and astronomy at Iowa State University, has been working on it.
“Stellar gerontology” - that is what Willson calls her work. It is because she studies red giants, the stars that expand and burn red and relatively cool as they move through the final stages of their life cycles.
