Just wanted to share this again because BlueSky had a big outage when I shared it the first time. My latest for Scientific American:

My grandfather fixed radios on the Black side of town. White-owned repair shops also brought him radios they couldn't fix. He made enough money to open a few grocery stores as a "retirement business".
My latest for Scientific American! The prime numbers -- math's "fundamental particles" -- may help to unravel some of the universe's most elusive secrets.

Thanks for the read!

Does the warp engine's app need to be updated?
🖋️ thanks!
The continents may have separated 200 million years ago, but plumes of their soils still cross the ocean like postcards between ancient friends.

Thanks! The respite was brief -- cloudy again tonight leading to rain in a few days.
You're welcome!
Owl Nebula is a planetary nebula with multiple shells that give it an owlish appearance-- an outer sphere and an inner torus-like structure. The Surfboard Galaxy is a jumbled ness of star forming patches and evidence of past interactions with the Universe's interstellar tides.
After weeks of rain -- the Owl Nebula soars high above the Surfboard Galaxy, which surfs enormous interstellar tides.

Waxing moon -- we had a stormy day (with lightning and thunder!) so this is one I took about a month ago.
I just realized that today is Chinese New Year, the 1st day of Ramadan, AND Fat Tuesday. That means the Chinese new moon lined up with the Ramadan crescent and also fell exactly the right amount of time before the Easter full moon.
An extremely rare lineup of 3 major moon-based traditions!
International Women in Science Day fell on Feb 10th. I had the honor of being featured in a blog post by the smart telescope company Vaonis (the brand of telescope I use)!

It's one of these "smart telescopes". 2" aperture, very transportable. The Seestar range is probably the most popular, but I have a Vespera.
Thanks!
An oblong red gas cloud with stringy filaments against a black background. There's some blue too from OIII emissions.
Just like the snake-haired Medusa of Greek mythology, this nebula's head writhes with tangled thick filaments, leading to its name, the Medusa Nebula. The result of a star cooling into a white dwarf.

It looks a little bit like a Roman amphitheater -- I can at least see the illusion of steps.
Gorgeous shot! I can see the crater clearly. Mine was taken in California.
Remarkable!
Lucky shot! Looks like it was also taken last night.
Thanks!
"...Aristarchus has brought out a book consisting of certain hypotheses... His hypotheses are that the fixed stars and the sun remain unmoved, that the earth revolves about the sun on the circumference of a circle, the sun lying in the middle of the orbit..." -- Archimedes, _The Sand Reckoner_
Gorgeous image!
Can you believe, that in the next weeks to a few months, there are going to be four humans which are going to go in a spaceship and sail around the other side of this other world that just hangs in our sky.
Go look at the Moon.
Four people will be on the other side of it soon.
An 87% full moon with a bright spot on the lower left.
See the solitary bright crater on the lower left? It's named after Aristarchus of Samos, who proposed that the Earth orbits the sun 1,800 years before Copernicus. An unbelievably insightful idea for its day (sadly ignored).
Image taken tonight by my tiny telescope.

A drooping string of glowing galaxies. They only appear to line up as seen from Earth. If you were able to look from a different angle, they wouldn't appear to be spaced so closely together. On the lower left is M87, a bright galaxy with a supermassive black hole. It coincides with the dark-matter-dominated gravitational center of the Virgo Cluster.
The beautiful Markarian chain, a drooping string of distant galaxies. And the loner who refuses to join the party, M87 on the lower left, hiding a supermassive black hole inside its heart.

Not many connect math and Dr. Martin Luther King. But in 7th grade, I saw my geometry teacher silently weep through the school's MLK Day assembly, hiding his eyes behind a napkin. An unintended gesture that placed a symbolic welcome mat in front of his math-covered chalkboards.
😲 did you ever chat with him?
Thanks!
Thank you
Thank you
