As this project makes use of a new form of zooniverse task we're expecting some teething issues. Below are some FAQs, and a list of all the bugs we know about.

FAQs

The project does not work on mobile phones / tablets

The nature of this project makes doing it on a phone or tablet pretty tricky - we'd recommend sticking to Galaxy Zoo while you're out and about!

Q: What is the score? Should I just be trying to get the highest version possible?

The score is a numerical representation of how close to uniformly black the image is after you have subtracted the galaxy you have created. This is useful in a lot of cases, however when bits of the galaxy have been masked out, or there's a star in the image our preparation pipeline didn't identify the number may not be helpful. We don't know in advance what the best score is for a galaxy.

Ultimately the strength of using citizen scientists is their intuition and ability to use more complex information than just maximizing a score, so whenever possible please just build the best galaxy you can!

Q: Why don't I have the option of seeing all the images at the same time?

The way we render galaxies in the browser means that showing both your model and the difference between your model at the same time could put a lot of pressure on your GPU. To make sure lower-end computers can still run the project we decided it was best to restrict things to flipbook-only for the time being!

Q: I'm getting a WebGL error

This project requires a browser which is compatible with an extension called WebGL, which is standard in most browsers and operating systems. If you have a different browser to try that'd be fantastic, otherwise please PM @tingard your operating system and browser version and we'll look at what we can do. Could you also go to https://get.webgl.org/ and report whether it identifies your browser as being WebGL-compatible
