I'm sure #TeamVeggie who called for more CO2 will be happy to update their position on this critical issue, now that they have this information...

"Seeing how dramatic some of the nutritional changes were, and how this differed across plants, was a big surprise"... We aren't seeing a simple dilution effect but rather a complete shift in the composition of our foods"...

M11 is an open cluster located about 61oo ly away in the constellation of Scutum.
Open clusters are groups of stars that were formed more or less at the same time in the same star forming nebula. This makes them useful in the study of how stars evolve through their lives. #astronomy

The one where we showed the world what Rubin can do...and, wow 🤩
On June 23, NSF–DOE Rubin Observatory unveiled its First Look images!
These large, detailed images showed why Rubin's 10-year survey will revolutionize our understanding of the Universe. 🌌 #RubinRecap2025 🔭🧪

No big deal, but the Alberta government just increased the fee to submit a citizen initiated petition from $500 to $25, 000. After the separatism initiative was approved, but before Corb Lund's coal mining petition gets re-approved. No political shenanigans going on here.

M1, the Crab nebula, is a supernova remnant located about 6500ly away in the constellation of Taurus.
The supernova that created M1 was observed and recorded by Chinese astronomers in 1054. The actual explosion would have happened 6500 years earlier. #astronomy

NGC 6058 (blue object, centre) is a planetary nebula located about 11 kly away in the constellation of Hercules.
Planetary nebulae are the penultimate stage of evolution of stars like our Sun. The star has blown off its outer layers and the remnants of the core cause that gas to glow. #astronomy
