'Tis the season to search for lumps on plants, aka galls! These growths are created in response to other organisms — often insects, fungi, or bacteria — injecting their chemicals into the plant. 🧵⤵️

Join the gall celebrations: tr.ee/ziMCEH
This gall looks like something you'd imagine a mythical fairy-like creature living in. It's shaped like a mushroom and has a small hole in the front. The stem of a plant has a couple round growths with small holes in them.

Strangely specific question, but I couldn’t find an IAU WGSN email. Is there a reason Nganurganity and Unurgunite are listed as separate stars in the catalog when they share a designation and HIP and are both names for Sigma Canis Majoris on Wiki? @iau-wgsn.bsky.social @dorisvickers.bsky.social

The latest update to our free and fun Seek by iNaturalist app adds more than 60k species to its image recognition model!

It will now also use your location to provide more accurate IDs!

A hand holds a smartphone in front of a plant with blue flowers. The phone's screen is open to the Seek by iNaturalist app and the app identifies the plant as Blueblossom. Next to the phone, text says "New Update. Seek can now identify over 80,000 species & uses your location to provide you even more accurate identifications.
