Over this longest night of the year, working on a welcoming page for my astronomy students next semester! #goodnotes

[Patrick M. Len @Patrick_M_Len]

My notes from tonight on answering student questions on Feynman diagrams. #goodnotes

@achmorrison Or set a scale, then assign a different star or exoplanet for each student to draw (with appropriate color for the star; or features of nearest solar system planet analog, etc.), and bring to class--then everyone gets to see all of them in an ensemble. Then, sorting activities!

The sun introduces some other low-mass stars. Also, the sun's expressions pretty much sums up how I feel about things right now.

@achmorrison Thank you! Maybe define the scope of the project to some straightforward, like look up and draw several stars/planets/moons to scale, and find/compare to a definitely not-to-scale illustration?

[Patrick M. Len @Patrick_M_Len]

Somehow I associate "low-mass" with "low-key."

[Patrick M. Len @Patrick_M_Len]

Forecast tonight for the Central Coast is for fog/cloudy skies, so it’s not looking likely there will be a good view of the partial lunar eclipse starting in two hours.

In the meantime, enjoy tonight’s astronomy-related doodle. See if you can identify everything in it.
