Did you know that different regions of the sun rotate at different rates? The sun is not a solid object, so rotation speeds can and do vary with latitude. The sun rotates once every ~24 days at the equator, and once every ~30 days at the poles!

Solar Rotation Varies by Latitude - NASA
The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots.

Did you know all 4 outer solar system planets have rings, not just Saturn? Jupiter‘s rings are divided into 4 sections, Uranus has 13 known rings, and Neptune has 5!

When your professor asks you to create a plot for stellar Teff vs. Mv, and that's too easy, you do it in Python and learn a bit about MatPlotLib :)

Work hack:
Put common LaTeX commands into the "text replacement" option on a Mac. In the rare case you want to type these literally, you can just use ESC after typing.
(They magically don't interfere with Overleaf, and putting in lower case Greek letters makes upper case work, too!)

JWST managed to determine the composition of three planets in the HR 8799 system. They found that the planets are all similarly enriched in heavy elements compared to the star, similar to Jupiter here. A bit surprising considering formation models.

Take note of the strong warning NOT to use these tables directly for population or exoplanet demographic studies!
