My favourite publications. Love sifting through them. I hope Trump doesn’t put the kybosch on Astronomical Phenomena 2027. Always tricky tracking that one done and purchasing.

@pfwaus This is what I look like.

@JohnBarentine In Sydney I think we eventually influenced the Sydney City Council split the CBD into zones and defined appropriate luminaires for each zone. So the older more historic sections like The Rocks have lower CCT and lower levels. Unfortunately I don’t know if this is the case.

@ElinaMia34 Happy birthday anniversary.

⚠️ Planetary crossing!
In 2025, Mars and Venus crossed paths with Messier 44 (the Beehive Cluster), ~600 light-years away. This composite time-lapse shows Mars (top) and Venus (bottom), captured from Chile, Bolivia & the Czech Republic.

@globemakers Love your work. Ever do astronomy globes? When I win the lottery I guess. Have a safe and fun New Year for 2026.

"New research, led by NASA Ames scientist Alejandro Borlaff, expects that by 2040, about 40 percent of all images from the Hubble telescope will be contaminated by internet satellite constellations."

@pfwaus No Western horizon, but actually very nearby - 300m maybe. Can’t get there not simple mainly because not well.

[SOLIS Sydney @SOLIS_Syd]

Oops … missed it this morning. Woke up and thought it must be the Solstice - didn’t check.

[Peter F Williams @pfwaus]

Happy Solstice Day to those who celebrate the northern most point of the sun's journey & the birth of a new (northern hemisphere) cycle towards warmth & light.
