Space Bluesky, I'm looking for a dark energy expert who is currently awake that could comment on an upcoming paper for me.

If that's you, do let me know. jdaoca[at]gmail[dot]com

Thanks!

Nice #GeoQuiz :)

There are 4 pins on the interactive map isspix.com/ISS073 for your post.

"Vaguely speaking" - so others can do your quiz - they are: western #Canada, near enough to #Australia, somewhere in southern #Africa, & around central #Africa.

Daylight saving time ends tomorrow, November 2 — which means it’s almost time to fall back an hour. 🍂🕑

Every year, Canadians debate whether we should keep changing the clocks or stick to one time year-round.

What do you think? Should Canada get rid of daylight saving time, or keep it?

A slightly different take on sharing a spooky Halloween image... This one is aimed to scare the bejeezuz out of all you vampires out there!

Happy Halloween to all who celebrate!
