What You Can’t Imagine

Samaritan's Song

I found a fascinating article this morning while I was reading the news: a telescope in Australia has shown what the universe would look like if the human eye could see radio waves.  Here’s the quote explaining why, precisely, this is so cool:

“The human eye sees by comparing brightness in three different primary colours – red, green and blue,” Dr Hurley-Walker said.

“GLEAM does rather better than that, viewing the sky in 20 primary colours.

“That’s much better than we humans can manage, and it even beats the very best in the animal kingdom, the mantis shrimp, which can see 12 different primary colours,” she said.

If you scroll down to the bottom of the article, you can see the wide array of images taken.  But I’ll include one here so that you can grasp how cool this is:
