Using Google Earth in Sky mode is a fun and interactive way to explore the universe. By importing images from
But something’s been missing, say astronomers Jiangang Hao and James Annis at the Fermi National Accelerator Laboratory. Google Sky’s view of galaxy clusters is fuzzy and incomplete. That’s because the program uses low resolution pictures to speed up image transfer over the web. To have higher resolution images, you need to add in better pictures yourself.
Luckily, Hao and Annis have made this easy. They’ve loaded about 100 scans from one stripe of the sky onto a public server at Fermilab, and made them available in Keyhole Markup Language (.kml files), the Google Earth equivalent of html files for web browsers. If you already have Google Earth, the whole thing takes a remarkably simple one-click download.
The full instructions are available in a paper posted to arXiv.org, and the files are posted on the team’s website. Enjoy!
