Interesting X vs Bsky comparison that reflects on userbase science engagement: identical post below by @scifri.bsky.social posted at same time on both X & 🦋 had 10x more reposts & likes on @bsky.app which has about 15x fewer users (40M vs 600M).

TIL part 2: Wikipedia’s picture is called “Today’s featured picture“ — akin to “Today’s featured article”. Wikimedia Commons’ POTD is independent.

Odd that the @wikipedia.org app displays the Commons’ POTD instead of Wikipedia’s featured picture.🤔

“This image was selected as picture of the day on Wikimedia Commons” — stated on the Commons page for the image (link in my OP).

TIL: Wikipedia’s POTD is different from @wikicommons.bsky.social‘s POTD. Unexpected, but 👌.

Revised magnitude is M 4.4

"we asked 490 researchers in T32 training programs how likely they would be to go into science if they were a graduate student now...

277 responded: Most were relatively unlikely to choose to pursue science again, only ~1/3 being somewhat or more likely to do so."

I usually research hashtags before using them, but did not for the above tweet, going for “feeling lucky” mode.

Did not have high hopes for #myrmecology, but that tag is hoppin’ on Bsky.

Swung by Emeryville Beach to check out the waves from Russia’s Kamchatka quake (M8.8) ystrdy. 🌊 video recorded at 14:06 PDT.

Tsunami warnings canceled. Waves not as bad as expected (just 5.7ft in Hawaii). Live updates: www.cnn.com/world/live-n...

No special filter, but I did use a general 'enhance' in Google photos which mostly just brightens things up a bit, brings out the natural color.

The water color comes from "rock flour" created by glaciers (see link in my 2nd photo of this thread). Here's an explanation from a mural at Peyto Lake:

Just up road from Bow Lake is Peyto Lake, with an awesome viewpoint deck above the lake, accessible via a short hike.

The cloudy, iridescent blue-green water is a from glaciers grinding rock into a fine silt suspended in the water = "rock flour" en.wikipedia.org/wiki/Rock_fl...

Added a banner image to my bsky profile: a condensed view of Bow Lake near Banff National Park, Alberta Canada. Photo was taken on 4 July 2023. The full, uncropped, unsquished version is included here. Shot with an iPhone 12 mini.

I came across a bit of space history last night. OAO-2 Orbiting Astronomical Observatory 2, the first successful space telescope launched in 1968, passed by the planet Saturn while I was using the Google SkyView app. See my screenshots below.

Btw, this was my first ever post on @bsky.app 🦋 — actually a cross-post from my #X acct, where I also noted:

1) Tsunami warning has been cancelled for CA & OR

2) Cool live aerial video stream over San Francisco Bay following earthquake
