The fact that they can look at a star 13.8 billion light years away (and ago) and tell us what it's made of is truly stunning. And rather than taking an exposure for weeks like Hubble, it took just a few minutes before breakfast.

Great discoveries are about to be made.

Edit: Water vapour and cloud detected in an exoplanets atmosphere 1000 light-years away. 👍

I heard "galaxy" and "13.1 billion light years". Am I wrong?

Yes, sorry. My typo, was galaxy.
