[alt text by NASA] The Moon, seen here backlit by the Sun during a solar eclipse on April 6, 2026, is photographed by one of the cameras on the Orion spacecraft’s solar array wings. Orion is visible in the foreground on the left. Earth is reflecting sunlight at the left edge of the Moon, which is slightly brighter than the rest of the disk. The bright spot visible just below the Moon’s bottom right edge is Saturn. Beyond that, the bright spot at the right edge of the image is Mars. Credit: NASA

Whoa 🤯

The Moon, in full eclipse, with the #Artemis II Orion spacecraft. Part of the Moon and spacecraft are lit by Earthshine, and both Saturn and Mars are visible to the lower right. Incredible. Details: images.nasa.gov/details/art0...

I got so annoyed with some of You People that I made a meme

Science is not why you and your family are struggling, friends. President Trump and Congressional Republicans are the reason why you and your family are struggling.

Gray whale that swam 20 miles up Willapa River has died A young gray whale that swam about 20 miles up southwest Washington’s Willapa River this week has died, ending a strange journey that drew widespread attention.

Sad that it died, but maybe this enterprising gray whale in the Willapa River just wanted to show the salmon how real carcass enrichment works? I hope this turns into a bear bonanza, that would be awesome. Nobody tell Oregon.

happy #sturgeonsaturday (on sunday)! 🧪👩🏻‍🔬🌐🦑🌎

did you know that sturgeon rely heavily on scent & feel to find food rather than eyesight?

in the photo you can see the barbels (like whiskers) & the 2 nostrils - which are basically the same size as the eye!

these strong sniffers are quite impressive 👃

happy #sturgeonsaturday !

this is the time of year that sturgeon wake up from their overwintering cuddling and move around in search of food!

in the Fraser River, BC this usually aligns with the eulachon spawning run, a crucial sturgeon food source, full of fat after a long winter 🍽️

An Army Corps project could wipe out one of Florida’s last thriving coral reefs The fate of one of the last thriving coral reefs in Florida may be imperiled by plans to widen the shipping channel leading into Port Everglades.

The US army corps of engineers is considering, right now, what would be the largest destruction of coral reefs in US history. To make a port slightly bigger.

People know this, right?
