And, yes, the lens is from Napolean III, the nephew of Bonaparte, the first president and second emperor of France. He gifted the lens to Notre Dame around 1866.

I went down a rabbit hole of the history of astronomy at the University of Notre Dame and found this gem in the 1873-74 annual catalog.

In essence what they're saying is losses matter. Well, if that's the case, how about 3-loss Alabama? They got crushed by Georgia and lost to a not great FSU. (And Oklahoma…) ND’s losses were by a total of 4 points to top 10 teams.

Recorded during 2024, this year-spanning series of images reveals a pattern in the seasonal drift of the Sun's daily motion through planet Earth's sky. Known to some as an analemma, the figure-eight curve was captured in exposures taken only at 1pm local time on clear days from Kayseri, Turkiye. Of course the Sun's position on the 2024 solstice dates was at the top and bottom of the curve. They correspond to the astronomical beginning of summer and winter in the north. The points along the curve half-way between the solstices, but not the figure-eight curve crossing point, mark the 2024 equinoxes and the start of spring and fall. Regional peaks and dormant volcano Mount Erciyes lie along the southern horizon in the 2024 timelapse skyscape.

They did not move back finals. Period. In fact, they moved them up a day (and had some on Saturday) to make sure no one had an exam today.

There's so much stuff on our social media timelines that we scroll past quickly, maybe with a "oh cool" and then moving on, but if you stop and think about what you are seeing here, it's really amazing.

You're watching a high-resolution panorama view from *another* *world*.

Wow. Just wow. πŸ”­

The UNC Athletic Department runs a $17M deficit this year, so they up the coach’s salary from $5M to $10M?

Whoa. I’m just learning that β€œIstanbul (not Constantinople)” was not originally a They Might Be Giants song??

There’s a parallel here to the astronomy literature I suspect: when old folks like me think β€œno one remembers anything from before 2000…”

You know, when you think about it, the blame for Donald Trump’s continued presence on the political scene can be traced to one clear moment. That’s right, I’m talking about when the Democrats wouldn’t let Mitt Romney (a Truly Decent Manℒ️) become president in 2012.

I mean, they clearly had a prejudice against allowing him to do whatever the hell he wanted.

That’s how they treat the masses, but as a billionaire, he shouldn’t just take that kind of crap.

NOIRLab just dropped a detailed atlas of almost 400,000 nearby galaxies! (Each galaxy is a collection of billions of stars...) The Siena Galaxy Atlas - designed to be the preΓ«minent digital galaxy atlas for large local galaxies - was produced NOIRLab telescopes. noirlab.edu/public/news/...
