Science Centers and Planetaria as Citizen Science Platforms
Wouter Schrier and Pedro Russo EU Universe Awareness / Leiden Observatory, the Netherlands [email protected]
Now: New (web) technologies:
- Much more information available - Faster and more direct ways of finding scientific information, even the actual data!
People expect of Science Centers to use real scientific data in their products
Scientists are no longer the information gatekeepers!
OPEN SCIENCE
Before: When you wanted to know about scientific topic: - Public science talks - Science Center - Library
Uniview – the Known Universe
Interactive planetarium systems showing the known Universe as mapped through astronomical observations
Digital Universe Atlas: - 4-D map of the Universe maintained/updated by astrophysicists at the American Museum of
Natural History; - Every object represented to scale and its correct measured location according to the best
scientific research to-date.
Hardware ranges from single projector flat screens to fulldome projections Currently more than 100 Uniview installations at science centers around the world:
- American Museum of Natural History (New York, USA) - Haus der Astronomie (Heidelberg, Germany) - Denver Museum of Nature and Science (Colorado, USA) - ...

World Wide Telescope
Explore the Universe using imagery from the best ground and space-based telescopes
Web-based Visualization Software that enables computers to function as a virtual telescope at multiple wavelengths - Constructed from observations from the Hubble Space Telescope, the Chandra X-ray observatory, Sloan Digital Sky Survey, …
Understand the cosmos through narrated guided tours from astronomers featuring interesting places/phenomena in the sky
Web/Desktop to Full Dome Planetarium capabilities

Globe4D
Interactive installation for immersive 4-dimensional globe viewing
Playful and interactive way of learning how global processes on Earth work and evolve(d) - Continental drift, seasonal changes, global effects of changing the waterlevel,
tsunamis/earthquakes, migration patterns, …
Globe4D installations in multiple Science Centers around the world: - Civel Experience Change Weather Center (Seoul, South-Korea) - Old Observatory Science Center (Leiden, the Netherlands) - Technoseum (Mannheim, Germany) - ...

“Citizen Science”
Let the public participate in the Scientific Process
Public can help systematically analyze/identify data-sets collected by scientists that computers cannot
Go through Hubble archives in search of ‘hidden treasures’
Help search in crowded radio bands for extraterrestrial in radio signals from space
Galaxy Zoo
Global Citizen Science project to classify galaxies according to their shape
launched in July 2007, with a data set made up of a million galaxies imaged with the robotic telescope of the Sloan Digital Sky Survey (SDSS) - Within 24 hours, 70.000 classifications per hour received - More than 50 million classifications from 150.000 people were received in first year
Volunteers were asked to classify SDSS galaxies as belonging to one of six categories – elliptical , clockwise spiral , anticlockwise spiral, edge-on galaxy , star/don’t know, merger
http://www.galaxyzoo.org/
Science question: Do spiral galaxies have a preferred direction of rotation?
Initiated by Adler Planetarium
Galaxy Zoo
Other (unexpected) results: - Much larger number of Blue
Ellipticals than initially thought
- Astronomers previously thought that all red galaxies are elliptical
- Discovery of ‘Hanny’s Voorwerp’: gas-cloud heated by the jet from a black hole

Original Galaxy Zoo User Interface
Science question: Do spiral galaxies have a preferred direction of rotation? NO
NOT TRUE!
Galaxy Zoo
Very Successful! - 24 papers published - More than 250.000 people have taken part already - Currently at third iteration: Galaxy Zoo - Hubble

“Galaxy Zoo: exploring the Motivations of Citizen Science Volunteers ”, M. Raddick et al. 2009
Motivation?
- Astronomy - Working with real data - Contributing to real science
Cerberus http://www.cerberusgame.com/
Goal: Use Citizen Science to create a surface map of Mars using data taken by the Mars Reconnaissance Orbiter (MRO)
Web-based computer game Serious gaming:
“A game designed with educational purposes” - Motivation: * Game: Fun – achievements – ranking/scoring – social element * Education: Learn something about cartography/Mars – contribute to Science
Developed by Blackshore Creative

- Bring the news from Observatories/Science Centers to the public!
- Weekly breaking astronomy news update for children of 8+
- Collaboration with ESO, NASA Chandra, ASTRON, Royal Astronomical Society, South-African Astronomical Observatory and Europlanet
- Share with children the excitement that the latest scientific discoveries bring
- Demonstrate that there is still much to learn about the Universe – research that they could contribute to in the future
- Translations in 15+ Languages

Conclusions
Science Centers can initiate and/or support Citizen Science projects e.g. Galaxy Zoo, other Zooniverse projects
Science Centers can act as a facilitator for Citizen Science e.g. Cerebrus
Citizen Science can act as a follow-up for Science Centers - Science Center excites the public, which then can stay active on the topic by getting involved in
the Citizen Science project OR - Science Centers can act as a follow-up/physical ‘helpdesk’ for Citizen Science projects
By interacting with real scientific data, people…: … Feel closer to reality and by such feel more engaged in the actual scientific process … Get a much better understanding of the science and processes … Are much more motivated … Can actually contribute to the Scientific Process
