The project Sun4All aims to promote science in general and astronomy in particular. The project is based on an asset of over 30000 images of the Sun (spectroheliograms) that are kept at the Astronomical Observatory of the University of Coimbra, as result of a work of over 80 years of daily solar observations, started in 1926. This is a Sun observation collection of great scientific value.
The project aims at involving all citizens in the analysis and counting of the sunspots is a very important aspect of the study of the phenomena occurring on the surface of Sun and to understand the solar activity and solar cycle. On the other hand studying the sunspots, besides being interesting itself, presents an important tool to understand much of what happens on the Earth climate.
How can I collaborate?
In this application you’ll find an image of the sun - a spectroheliogram - dated with the day when was taken. The purpose of this application is to count sunspots and sunspots groups. To do that, we provide you with tools to manipulate the image and to do the counting.
To Know More

This is a project promoted by researchers at the Department of Mathematics of the University of Coimbra and the Astronomical Observatory of the University of Coimbra. The application was developed by the team of SOCIENTIZE project.
What is the perceived relation between words? This is still a complex issue for semantic specialists. This experiment uses a video-game in order to create a semantic map where volunteers define the distances between words. Semantic analysis is a major challenge for science and innovation as it's a very complex task requiring advanced models and experts validations. A common technique is to determine which words are very similar or have a related meaning. Related words can be considered as neighbors in a graphic map. What we will create is a citizen science application based on a gaming approach, which will trace the distance of thousands of words. We will ask people to select which words lead from one fixed starting word to the goal word creating a visual map of distance between words. Results of this research will be important for the scientific as well as the business world with lots of applications being based on semantic analysis. New generation of web sites will be constructed over the semantic keys.
How can I collaborate?
As a game, we created a semantic map in which people define the distances between words. Thus, any citizen can test the application and step will be contributing to the semantic analysis, a common technique to determine which words are similar or have a related meaning.
