A team from Southern Illinois University in Edwardsville has developed the website IceHunters<\/a> , which challenges the public to discover potential destinations for a NASA mission at the very edge of the solar system set to happen around 2015.<\/p>\n

\u201cI think it\u2019s a great idea,\u201d said Yanga Fernandez, a University of Central Florida<\/strong> physics assistant professor and comet expert. \u201cActually that’s kind of how I started. When I was 10, I used to search the sky for interesting objects with my dad. And in high school I worked hard to find Halley’s Comet, which wasn’t easy in suburban Florida. I learned a lot of astronomy along the way.”<\/p>\n

Today Fernandez holds a Ph.D. degree in astronomy and is among the world\u2019s experts on comets. He is part of an international team that recently published two articles about comets visited by spacecraft. The articles appear in recent issues of Icarus<\/em><\/a> and The Astrophysical Journal<\/a> <\/em>. Fernandez, who grew up in Washington and Florida, also is working with another international team to take a unique survey of about 100 comets using the Spitzer Space Telescope and Earth-bound telescopes to determine some of the properties of typical, run-of-the-mill comets.<\/p>\n

Fernandez said the IceHunters challenge will not only excite people about space exploration, but it also gives scientists potentially hundreds of extra eyes.<\/p>\n

\u201cUp to now, what we know about comets is based on comets of opportunity,\u201d Fernandez said. \u201cThere are several comets like Halley that people can probably name. We know quite a bit about them because they have come close enough to earth or are bright enough for us to take a pretty good look. But we don\u2019t know much about the vast majority of comets out there because they are so far away.\u201d<\/p>\n

For the contest, dozens of images from the Kuiper Belt \u00a0— an area beyond Neptune at the outer edges of the solar system — have been taken by powerful telescopes and posted on the website. Participants are invited to view the images and mark potential targets of interest. Guidelines and a brief tutorial will help volunteers interpret what to look for in the images. The site is called IceHunters because objects far from the sun should be cold and icy.<\/p>\n

But this isn\u2019t simply an academic exercise. The New Horizons mission that launched from the Kennedy Space Center in 2006 is on its way to the outer solar system. The spacecraft flew past Jupiter in 2007 giving scientists a wealth of new data. It is scheduled to rendezvous with Pluto in 2015.<\/p>\n

If the right object or objects can be found \u2013 anything from comets to asteroids to other unknowns \u2013 the spacecraft will take images and other measurements and beam them back to Earth for study. After the rendezvous, scientists believe the spacecraft will have just enough fuel to head deeper into the Kuiper Belt.<\/p>\n

\u201cThis type of amateur-professional approach benefits all of us,\u201d said Humberto Campins, an international expert on asteroids and colleague of Fernandez at UCF. \u201cIf this collaboration does identify an object accessible to a rendezvous with NASA\u2019s New Horizons spacecraft, the contributions to this mission and to our understanding of the outer Solar System will be significant.\u201d<\/p>\n

For Fernandez, the challenge recalls that spark in his childhood that led to a lifelong career.<\/p>\n

\u201cMost of us start out as amateur astronomers whether it\u2019s in our backyards with a pair of binoculars or on a balcony with a low-powered telescope,\u201d he said. \u201cThis is just a way to take advantage of all the passion and interest and, hopefully, inspire the next generation of space explorers.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"A team from Southern Illinois
