Happy birthday to Niels Bohr! 🥳 As per tradition, today was the institute's annual picture day. A tour of his office served as a reminder how much of (astro)physics derives from quantum theory he pioneered – together with many seeking refuge from authoritarians in Denmark...

We confirmed the tiny green blob below to be a galaxy so distant it is seen when the Universe was only 2% of its current age, and… its spectrum came out as a huge surprise! 📈🔭 Read more in the excellent summary by @Kevin_Hainline who first discovered this galaxy 👇
Let's chat. This is a spectrum of a galaxy, JADES-GS-z13-1-LA, a source I discovered last year as part of my big high-redshift catalog. This is the spectroscopic confirmation of it being at z = 13 from @JorisWitstok's recent paper (. Wait, what's that?

How to fool an astronomer: check out Kevin's video on why it took more than a year to see through the disguise of JADES-GS-z14-0 and break the redshift record!
I've made a (30 minute!) video describing the discovery of JADES-GS-z14-0, it's implications, and why the galaxy holds the distance record for now, it's so exciting to continue to push to earlier and earlier times in the history of our Universe.

Excited that we can finally share our latest @ESA_Webb discovery! To call this galaxy surprising would be an understatement: not only does it shatter the redshift record, but also all our expectations of what such early galaxies might look like... 🌌😱
🆕 Webb has found a galaxy observed just 290 million years after the Big Bang! 💥 Read more: or 🧵👇
