This week’s WITU Challenge image was sent in by a faithful reader of Universe Today who frequents the comment section as NeoGuru. I’ll not give any hints as to where NeoGuru got the image, or what it is, or whether this image can be found anywhere else on the web (for those of you that like to search online for the image and link the answer!). You’ll have to wait until tomorrow (Thursday) for the answer to be revealed for this week’s Challenge.
UPDATE: The answer has now been posted below — don’t peek before you make your guess!
To see a sight like this, you don’t have to look up, but look within…within the Earth, that is. These are glowworms found in the Waitomo Caves in New Zealand. The caves and these creatures look amazing! These worms light up to attract insects for food. They glow from bioluminescence which is a chemical reaction between a chemical they produce called luciferin, and air. The chemical reaction gives off light. Way cool!
