Can you see the Earth’s shadow?¹

¹ From Samil Cabrera (@astronycc ): “Full Worm Moon Penumbral Eclipse— Tonight’s worm moon featured a penumbral lunar eclipse, with the outer edge of the earth’s shadow cast on to the moon, causing it to appear slightly darker than usual.
This image is a stack of 300 frames during the maximum eclipsed moon at 3:12 a.m. ET.”
Pictured above: sand from Santa Monica and Venice Beach, California.
Captured by microbiologist and bio-artist Tal Danino, an Associate Professor at Columbia University, these images are of microbes from the sand of the beach, sampled, cultured, and grown under pattern-forming conditions (using different microbial mediums or growth methods) and stained and dyed for color.
Some of these microbes (see: Paenibacillus on Slide 3) can be seen forming localized clusters in “fractal-like” (or various extremely irregular curves and shapes) patterns as they swarm around their petri dish.
Tal—a long time friend of @seed —is a multidisciplinary artist and scientist engineering the invisible world of bacteria into works of bio-art. For the first time, a breathtaking collection of his most impressive pieces have been published into print from @rizzolibooks .
Releasing tomorrow.
“What a surreal place this is. Those two buildings are located on the peak of Fanjingshan, in the high mountains of Guizhou. The temple and pavilion up there have undergone renovations and reconstructions over time, but the first structures were built hundreds of years ago. It took considerable effort to hike up there, which makes it even more incredible to imagine how people in the past managed to construct on such a high and steep peak. When I visited, the fog was so thick that I waited for 3 hours until it cleared up a bit. Finally, I sent the drone up, and for a brief moment, I was able to capture the peak!” - Long-Nong Huang

¹ These are Darya Kawa’s most-detailed moon images ever. Here’s how Kawa captured them:
“1- I stacked (133,000) frames and 147GB worth of data to achieve this. I've been working on this project since 4 days ago. This image takes up to 22 hours of editing and stacking since the amount of data was massive, also you can see the planet mars as an apparent size compared with the moon which is composed image. Lastly, i hope you guys like it and enjoy the details.
Gear: celestron nexstar 8se
Camera: ZWO AS1120mc
Color: canon eos 1200D
Software: autostacker, astro surface, registax, photoshop.
2-I took almost a quarter million frames (231,000) and i spend unimaginable amount of work over the course of 3 weeks to process and stack all the data which was equivalent to 313 GB.
I used the most basic astronomical camera (ZWO ASI120mc along with my 8 inch telescope (celestron nextsar 8se) without a barlow i.e at prime focus 2032mm.
The mosaic moon was compromised with 77 panels each panel consist of 3000 frames. It is worth mentioning that i used canon eos 1200D to add mineral color on the surface.”

Saguaros are the largest cactus in the United States. They can grow up up to 60 ft tall. Can you guess how much they can weigh when fully hydrated?
Share your guess and check back here tomorrow for the right answer.

Updated Wednesday, March 19: When fully hydrated saguaros can weigh up to 4,800 pounds, ranging between 3,200 and 4,800 pounds on average.
360° of rainbow.¹ 🌈

P.S. Happy St. Patrick’s Day. 🍀

¹ Perspective shift: Rainbows are actually full circles. Why, then, do we typically see only a quarter or semicircular arc?
When sunlight and rain combine to create a rainbow, the light is refracted, reflected, and dispersed in the water droplets, resulting in a circle of colors. However, from our usual viewpoint on the ground, half of this circle is usually hidden below the horizon. But if you raise your vantage point (think: on top of a mountain or in an airplane), the full scope comes into view.
Here’s another 🤯 fact: Because each person’s vantage point is unique to them, no two people will ever see the same rainbow.
