www.eso.orgOxygen discovered in most distant known galaxyTwo different teams of astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0. The discovery, reported in two separate studies, was made possible thanks to the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. This record-breaking detection is making astronomers rethink how quickly galaxies formed in the early Universe.

*edited to add: sorry I see it as base 1 now!

@kvistgaard @tanishqkumar

Gosh thank you for telling me about this. If I understand correctly, it's base-0? Are there any articles for lay-readers on it? I regret those I found either explained it as something I'd interpret as base-0, and I found hard to understand how to create and compute abstractions from that foundation, or they seemed aimed at readers who were already thinking in terms of computing with those abstractions, and I was a bit lost!

My applications for fast computing would be things like Wide Area Motion Imaging or gimbaled sensors that have to make tiny movements with superb accuracy and speed in order to see things very very far away.

"Using 1,024 of what will eventually be 131,072 radio antennas, the first SKA-Low image shows a tiny sliver of sky dotted with ancient galaxies billions of light-years from Earth.

This first snapshot shows the system works, and will improve dramatically in the coming months and years"

First space image using world-leading telescope 'beyond what we hoped'
By Chloe Henville
