1. The document outlines an Erasmus+ school project between several high schools in Europe to analyze the universe through creating constellation maps, interactive sky spheres, and analyzing data from the Chandra X-ray Observatory. 2. Students will create interactive constellation image maps using GIMP and analyze spectra using online tools to understand chemical compositions. They will also create interactive sky spheres using code. 3. The document provides instructions and resources for students to find astronomical data, analyze X-ray data from Cassiopeia A using JS9 and ImageJ, and identifies common elements present in supernova spectra like oxygen, neon, magnesium, and silicon. It displays examples of student work analyzing Chandra data.

Analysing the Universe
Objectives
• One student analyse one constellation including myth or
history
• Creation of an interactive image map of a constellation
using GIMP Image Map option and mapper.js Javascript
library and locating sky objects. Another possibility is to
use skysphere.js library.
• Analysis of quick spectra using js9.si.edu website or
SAOImageDS9 software and imageJ to know the
chemical composition percentages.

Analysing data from Chandra
ACIS intrument
Advanced CCD Imaging Spectrometer (ACIS) is an X-
ray imager. X-ray photons hitting the camera are
detected individually and their position, energy and
arrival time recorded. This allows for high resolution
(~1 arcsec) imaging, moderate resolution
spectroscopy and timing studies.
