Gravity Simulator Sun for All Project download poster The project “Sun for all”, funded by Ciência Viva (2005 117/ 18) aims to promote science in general and astronomy in particular, among students. The project rests on the asset of over 30000 Sun images (spectroheliograms) that are kept in the Astronomical Observatory of the University of Coimbra, as a result of a work of over 80 years of daily solar observations that started in 1926. Presently there are about 15000 digitised images that are available to the general public due to another project, also funded by “Ciência Viva”, which was developed from 2002 to 2004. The solar observations collection has an enormous scientific value. Thus, this project aims to make this collection available in a digital way via WWW to Portuguese and foreign students, as well as a set of activities that enables them to use these images, in order to introduce them to the scientific method, having the Sun and its atmosphere as the background (see in "SUPPORTING MATERIAL").

Plate Tectonics - Crust, Lithosphere, Mantle Topics Plate Tectonics Crust Lithosphere Mantle Density Buoyancy Earth Science Description Explore how plates move on the surface of the earth. Sample Learning Goals Describe the differences between oceanic and continental crust, including their respective properties of density, composition, temperature and thickness.Predict how changes in composition and temperature change crust density and buoyancy.Draw a time series for different types of plate boundaries and their motions, indicating the related surface features.Deduce the type of plate boundary given images or descriptions of surface features.Explain which types of plate boundaries create crust, and which destroy crust Version 1.02 Le logiciel d'astronomie COELIX APEX Disponible sur cédérom ou téléchargé.

3D Solar System Web Global Hands-On Universe: Software SalsaJ is free, student-friendly software developed specifically for the EU-HOU project. SalsaJ is designed to be easy to install and use. It allows students to display, analyse, and explore real astronomical images and other data in the same way that professional astronomers do, making the same kind of discoveries that lead to true excitement about science. SalsaJ is multi-platform and multi-lingual: SalsaJ has been translated into many languages: English, French, Spanish, Italian, Polish, Greek, Portuguese, Swedish, Northern Sami, Arabic, Chinese. Current and older, legacy versions of the EU-HOU developed software may be downloaded by clicking here: SalsaJ download page. A current, beta version supporting interface emulation of the previous versions may be downloaded by clicking here: SalsaJ v2.05us-beta.

Europa’s ocean: Evidence of Jupiter’s moon ocean found on the surface. Image credit: NASA/JPL-Caltech He killed Pluto, but he may have just breathed life into Europa exploration. Astronomer Mike Brown*—discoverer of the giant outer-solar-system iceball Eris which is what started the machinery that kicked Pluto out of the planet club—has found some pretty strong evidence that Jupiter’s moon Europa has sprung a leak. Its undersurface ocean may be mixing with the icy surface, making it possible to understand its composition without having to dig down through dozens of kilometers of solid ice. Mind you, we’ve been eyeballing Europa’s ocean as a potential habitat for life for decades. This news is not evidence of life, but it does add reason to look at Europa even more closely. This evidence that the surface ice and undersurface ocean are in intimate contact comes in a series of steps, which I outline below. Image credit: NASA/JPL/Galileo The water is kept liquid by heating via tidal forces, the effects of the gravity of its massive parent planet. Got all that?
