A digital composite of our Moon designed for educational purposes. Created by artist Ildar Ibatullin, it combines a high-resolution telescope photo with precise surface height data to visualize the Moon's topography and mineral composition (Fe = red, Al = blue).
Cool!
"The bluebird is like a speck of clear blue sky seen near the end of a storm, reminding us of an ethereal region and a heaven which we had forgotten."

Spring has sprung!
I would guess Kash Patel because the Epstein survivors are suing him and he will definitely be deposed by their lawyers. And he will have to lie under oath and perjure himself like Pam Bondi did while she was being cross examined by Rep Ted Lieu.

I love this pic because it shows a beautiful bird in flight and motion. Thanks to Scott Farquharson for sharing.
Hey David, I read your FB post. So, have you really abandoned FB? I like Blueskys science page but its "likes" aren't as varied and convenient as all the different emojis on FB. Stay well!

Beautiful!
A magnified pic of a plant cell named Monstera deliciosa. The pic shows the stele or central vascular core in cross section. The cell is stained with FCA (fuchsine, chrysoidine, astrablue).

UTQIAGVIK, ALASKA—The northernmost city in the US is in a Polar Night. The sun set on Nov 18 won't rise again for 64 days.
During winter, the North Pole is tilted away from the sun, causing the sun to remain completely below the horizon.
The sun will reappear again in Utqiagvik on Jan 22, 2026.
Awesome Trilobite Selenopeltis from Ordovician with ancient fossilized Starfish, about 500 million years old!!
Driver's license photo of Mr. Cardinal in his official red plumage. Thanks Parvis Forghani for sharing.

Yes, it is. Many male birds dance for their partners ...NOT the other way around. I was in South Africa recently with my wife and we spotted some male and female ostriches together and one male had spread his wings and was swaying hypnotically in the wind. Fascinating behaviour!

Our ginger female cat Simba. We thought she was a male when we picked her up as a tiny kitten in a ditch at the side of the road in Huron County Ontario. Nope, she's a female who is smart and she already knew her name so we kept it.
Nope!
I wish the Red Roses well, but I'm cheering for our Canadian women. They rock!
Should be a good game to watch.
Good luck!
Some pics of my wife and my trip to Nungwi Beach, Zanzibar, Tanzania.
The tides ebbed and flooded every morning and evening like clockwork.
I felt that our tourist dollars helped to alleviate poverty, promote socioeconomic development and establish trust. It was fun!!
Penguin dancing is an aggressive display, usually done by the male loon, to defend its territory or chicks from another loon. This display is extremely energy intensive, and the bird may do it repeatedly until the threat moves away. Loons often yodel (males only) and tremolo when penguin dancing.

Why are you feeling depressed Laura? Are you lonely?? Or is there something else??
You're in the middle Laura ...in the second pic?
Sorry Emjay ... couldn't resist. Ha ha!
Male Northern Cardinals feed female cardinals during courtship and when the female is incubating their eggs. This behavior is a way for the male to demonstrate his fitness to provide for his mate and their potential offspring while they are nesting together. Cardinals are monogamous birds.
Travertine are colorful formations of rock in Hot Springs State Park, Wyoming. They were created by the mineral-rich hot springs and are a type of limestone deposited by the precipitation of calcium carbonate. The locals call this one the "Green Eyed Monster." Neat!
The JWST has discovered a bizarre exoplanet named WASP-12B that orbits so close to its star that temps soar. Its heavy metals vaporize, rise, and escape into space. This planet isn't round like Earth. Instead, the immense gravitational pull from its star has stretched it into a football-like shape.
We rock heads up here in Canada love our Lake Superior agates. Here's a mitt full.
And Canadians still love rock hunting in Michigan. We're just not so crazy about coming across the border at this time. The Yooperlites in Leland can wait. ICE might deport us for illegally taking Yooperlites. Sheesh!
There is compelling evidence of a vast underground ocean beneath Mars' surface.
The water resides within fractures in igneous rocks, where geothermal heat prevent it from freezing. This environment may be similar to Earth's deep subsurface habitats, where microbial life thrives without sunlight

The James Webb space telescope has found a planet called K2-18 that orbits a small red giant star 124 light yrs from Earth.
The planet shows evidence of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in its atmosphere. These two compounds are only known to be produced by life.
