Becoming An Ice Hunter

Just last week, I was praising and encouraging people to participate with the ambitious citizen scientist project, the Zooniverse. Now, if looking for exoplanets, identifying galaxies, examining the surface of the Moon, watching for solar storms, and studying the structure of our Milky Way Galaxy all sound boring to you (and really it shouldn't), then be prepared for their latest project: Ice Hunters.


Ice Hunters will have members of the public contribute in modern space exploration unlike any other way before. You can examine images from the giant Magellan and Subaru telescopes looking for Kuiper Belt Objects, or KBOs. These Pluto-like objects are lumps of ice, frozen chunks that exist on the fringes of our Solar System and may take millennia to circle the Sun once. Astronomers have already identified over a thousand KBOs, and there are likely tens of thousands left to be discovered.

Now, if discovering new objects in our own Solar System wasn't cool enough, you will help choose the next destination or two for a spacecraft to visit. The New Horizons probe is set to buzz past Pluto in July 2015, giving us an unprecedented view of the ice dwarf. Astronomers and researchers are on the edge of their seats for this encounter and are expecting to be amazed. But after New Horizons sails past Pluto, it is going to keep heading deeper into the outer solar system, deep into the Kuiper Belt, the territory of KBOs.

New Horizons has been given the capability to explore further objects than Pluto, and will be visiting one or two of them. With Ice Hunters, the KBOs found by the public will be considered as possible targets. KBOs have never been seen up close before, so your discovery may be one of the first of these objects ever studied up close and personal. Your discovery could lead to a bunch of new understanding about how our Solar System works, and maybe even an indication of how water was brought to the Earth.

It's an exciting prospect, especially for members of the general public. The site makes it just as easy as the other Zooniverse projects. Humans turn out to be really good at identifying these objects, were as computers tend to get confused by false positives in the data. You can read more about how it works here. That is why they need you. They need your eyes and your intelligence, there is far more data available than their are researchers.

Check out Ice Hunters and New Horizons maybe visiting your discovery soon!

Citizen Scientists

I have mentioned these kinds of things in the past, but I think it's good to reiterate, especially if you are a newer reader. I also like encouraging people to be involved in science and understanding the world around them. So, with the Planet Hunters site turning 6 months old, now is a great time to remind people that they can participate in making real discoveries.


Planet Hunters is part of the Zooniverse. According to their about page, "The Zooniverse is home to the internet's largest, most popular and most successful citizen science projects." The projects hosted include Galaxy Zoo, Moon Zoo, the Milky Way Project, of course Planet Hunters, and a couple others. For the most part these are all astronomy projects, and generally presented in a fun and interesting way to public to learn and make discoveries with.


For instance, Planet Hunters has found about 70 candidate systems for exo-planets. Candidates because they still have to confirmed by follow up observations to ensure they are real. But for the most part, these are likely real planets around other stars. This data comes from NASA's Kepler space telescope. There was so much data that researchers couldn't possibly go through it all, so they released it to the public for their aid.

So, now people like you can go online and, with minimal training, start hunting through Kepler data for exo-planets. It's one of those things, that once you start, you kinda get drawn into it. You will tell yourself one more, and 10 minutes later still be sitting there. It is also nice to feel like you are contributing to science. The best part is, if you find a planet, you get credited with its discovery. This is only something a handful of people on the Earth can claim to have done, discover a planet.

The other Zooniverse projects work much the same way. They use data from other great sources like the Hubble Space Telescope, the Spitzer Space Telescope, the Lunar Reconnaissance Orbiter, the STEREO spacecraft (two of them observe the Sun), and other world class telescopes. And again, the reasoning for why they NEED you is because there is such an overwhelming amount of scientific data that researchers just can't go through the piles and piles of it.

Space is huge. We all know that, so the more people that take a couple of minutes to lend a hand, the more we learn about the Universe. It also increases the number of people who have knowledge of this science, a better educated world. You can really learn a few things about astronomy from participating in these projects. It really is win-win, so go be a citizen scientist!

The thing with Planet Hunters being 6 months old though is that this week they're giving you the chance to ask just about anything of the project's scientists and developers. You can ask questions via Planet Hunters Talk at http://talk.planethunters.org/discussions/DPH100i962 or via Twitter using the hashtag #phlivechat. On Thursday they'll be hosting the first ever Zooniverse live chat. Representatives of the Planet Hunters team will be answering your questions live, thanks to Skype Video and UStream.
