You Can Hunt for Icy Worlds
Scientists have calculated where in the sky an object moving toward a potential meeting with the New Horizons spacecraft should currently be located, and they have used some of the largest telescopes in the world to image this region. Now, those images are provided to the public for searching via IceHunters.
New Horizon’s launched in 2006 on a journey that would carry it past Jupiter in 2007 and on to Pluto in 2015. After flying through the Pluto system, the mission will have just enough fuel left to change course toward one or more additional Kuiper Belt objects. The catch is, these future destinations have yet to be discovered. This is where the IceHunters website comes in: this SIUE-developed website is packed with millions of images that could contain the object New Horizons should visit. The public is asked to help examine these images for that sought-after target. Along the way they will discover large numbers of variable stars, asteroids, and other KBOs.
The IceHunters website was developed by SIUE assistant research professor Pamela L. Gay and website developer Cory Lehan. “Projects like this make the public part of modern space exploration,” says Gay. “The New Horizons mission was launched knowing we’d have to discover the object it would visit after Pluto. Now is the time to make that discovery, and thanks to IceHunters, anyone can be that discoverer.”
Studying objects in the Kuiper Belt can provide a wealth of data for astrobiologists concerning this mysterious region of the Solar System. In the past, KBOs could have traveled to the inner Solar System, impacting planets like Earth. These impacts may have shaped the evolution of life on our planet and, in the future, could affect the habitability of Earth as we know it. Impacts could also have delivered molecules to the early Earth that played a role in the origin of life.
“Using just about any modern Web browser, users can circle potential KBOs and mark with a star the locations of asteroids,” says Lehan. “The website is filled with examples to help get people started. Anyone should be able to take part -- no Flash required.”
Ice Hunters was developed within the SIUE Center for Science Technology Education and Mathematics (STEM) Research, Education and Outreach. This new research center works to define the most effective ways to teach children and adults about STEM topics. This work is part of SIUE’s ongoing collaboration with the Zooniverse collection of citizen science projects. Over 400,000 Zooniverse volunteers are already making important contributions to such diverse topics as the classification of galaxies in Hubble images, reconstruction of historical records of Earth’s weather, and analysis of close-up pictures of the Moon’s surface. The public is invited to become a part of this and all other Zooniverse projects at Zooniverse.org. The Zooniverse is administered by the Citizen Science Alliance.
