This website is exactly what it says it is – every day it has a new picture related to Astronomy with an explanation of what the viewer is seeing.
I use this website as a hook at the beginning of class during astronomy units. I have it up before the students come in and then we spend a couple minutes discussing the image. Some of the images are amazing and the students typically have interesting thoughts and questions about them. We can’t travel to space, so this website is useful as it gives us that opportunity. Students are excited to see what astronomy actually “looks” like.
