It’s December 1st and that can mean only one thing at The Zooniverse: our advent calendar returns! It’s time for another citizen-science-fuelled, festive charge at the unsuspecting Christmas break for many around the world. 24 digital days of fun from us to you, our lovely, lovely volunteers! It’s a fun way of saying thank you each year. To kick things off, behind door 1 is is a bit of digital wallpaper for you: a pair of galaxies made from galaxies.
This lovely mosaic was created by Galaxy Zoo‘s Kyle Willett who was the lead author of this year’s mammoth Galaxy Zoo 2 paper. Whether it’s galaxies like these or science like this that bring you to the Zooniverse, we hope you enjoy what you find.
Have a fun December, and check back on zooniverse.org/advent to see what we have behind the door each day.

It seems, that the given link for the Zooniverse Advent Calendar doesn’t work.
So I searched for “Zooniverse Advent Calendar” and found following link.:
https://www.zooniverse.org/advent
I’m confused because that is the same link! Did you find a different broken link?
I clicked the link in the blog post, and got “Firefox can’t establish a connection to the server at zooniverse.org.” More than once. Over several hours.
Has the GPair a catalogue number? What is its SDSS number?
Answering my own question: It is NGC 5257/8 aka Arp 240.

So, how do I keep the “windows” visible after opening them?
Previous days’ windows stay open by default, so today the Day 1 window should be fixed open.
