Last night, NASA's Perseverance rover looked up at the night sky once more, to capture interstellar #comet 3I/Atlas flying by the red planet.

The distance was "only" 0.2 AU or 30 Mio km, far closer than the comet ever got to Earth. 🔭 #3IAtlas

Each NASA-supported citizen science project has a summary page telling you the task you'll do as a volunteer, what's required of you, and how to get started. E.g., Snapshot Wisconsin invites you to inspect trail camera images for roaming wildlife. science.nasa.gov/citizen-scie... #scienceathome

I see what you mean. I’m struggling with the analogy to planets versus brown dwarfs though.

Marc Kuchner | Author @marckuchner.bsky.social · 20d

Good example! And you'll see that the word that refers to the formation mechanism is just a modifier on the word "species". You wouldn't eliminate an object from the base category (species) simply because of the object's history....it just acquires a modifier.

Marc Kuchner | Author @marckuchner.bsky.social · 20d

Well, this isn't the first time I've pushed back on peer reviewed literature. Name another instance -- from any field of science--of a definition that's based on how something formed not what something is! (and yes I'll admit there are some)
