Max Planck Institute for Astronomy animations

If we want to understand our own origins, then we need to understand the chemistry of stars.

Find out more by watching these two cartoons created by Angel Eye Media for M. Bergemann's Stellar Spectroscopy Research Group at Max Planck Institute for Astronomy, Heidelberg in collaboration with the Institute of Astronomy, Cambridge.

Gaia DR2 Gaia Sky videos and Virtual Reality resources

A series of videos made with Gaia Sky using Gaia Data Release 2 data: https://www.cosmos.esa.int/web/gaia/gaiadr2_gaiasky . Included are: Comparison of the Gaia DR1 TGAS catalogue with the new Gaia DR2 catalogue, Demonstration of parallaxes and proper motion in the northern sky, Demonstration of parallaxes and proper motions - 360 degrees video, Demonstration of the LMC rotation, Tour through the Gaia DR2 asteroids.

Several resources have been developed to visualise the extraordinary Gaia Data Release 2 data set, both for public outreach and scientific exploitation purposes. They include:

  • interactive videos, which can be viewed with a Virtual Reality Cardboard kit, 
  • GaiaVR Virtual Reality application (versions for Windows and Mac OS are available), which can be viewed with an HTC Vive virtual reality headset and a motion-tracked handheld controller (it can be used without HTC Vive as the 2D visualisation tool),
  • Gaia Sky VR, the Virtual Reality version of Gaia Sky, is a real-time, 3D, astronomy Virtual Reality software that runs on multiple headsets and operating systems thanks to Valve's OpenVR.

Gaia Data Release 2: A guide for scientists videos

"Gaia Data Release 2: A guide for scientists" is a series of 15 videos made by scientists for scientists. They are meant to give some overview of Gaia Data Release 2 and give help or guidance on the usage of the data. Also given are warnings and explanations on the limitations of the data. These videos are based on Skype interviews with the scientists. The videos are available from https://www.cosmos.esa.int/web/gaia/guide-to-scientists.

Gaia Archive Visualisation Service gallery

A range of resources for use in presentations of GDR1 data can be downloaded from the Gaia Archive Visualisation Service gallery (http://www.sim.ul.pt/gaia/dr1/gallery/ ). They include:

  • Images showing integrated GDR1 source brightness and source density maps (all-sky and selected regions).
  • All-sky maps in Hierarchical Progressive Survey (HiPS) format for viewing with Aladin or other software supporting HiPS (the maps are based on a HEALPIX grid with NSIDE=8192).
  • FITS images of some regions. Contours or other overlays and manipulations for analysis or presentation purposes can be done with DS9, IRAF, Python and other software.
  • Large format images for dome projection. Large 16384x8192-pixel all-sky panoramas in a Cartesian plane projection, suitable for use in modern digital planetaria.

Gaia Sky 3D visualization software

Gaia Sky is a real-time, 3D, open source astronomy visualization software that runs on Windows, Linux and OS X. It is developed by the Gaia group at the Astronomisches Rechen-Institut  (ARI) at the Centre for Astronomy of Heidelberg University. The release accompanying the Gaia Data Release 1 was built with TGAS (Tycho-Gaia Astrometric Solution, see Gaia Data Release 1) catalogue.

A Virtual Reality version of Gaia Sky, Gaia Sky VR, is available. Gaia Sky VR runs on multiple headsets and operating systems thanks to Valve's OpenVR.

Download Gaia Sky.

Gaia Mission app

University of Barcelona has developed a mobile app for iPhone, iPad, and iPod touch. The app allows you to explore the satellite, and learn about the mission and its science. The app is available for download from iTunes.

The Gaia app for Android devices is now also available for download from Google Play. Download Gaia app for Android devices.

Google Chrome 100,000 Stars visualization

100,000 Stars is an interactive visualization of 100,000 stars in the solar neighbourhood. The application uses data from three sources: Hipparcos, Yale Bright Star Catalog, and Gliese/Jahreiss Catalog. It is a Chrome Experiment developed by the Google Data Arts Team. You can try the visualization at http://stars.chromeexperiments.com/.  More information about the application can be found at https://experiments.withgoogle.com/chrome/100000-stars and https://www.html5rocks.com/en/tutorials/casestudies/100000stars/.
