I just got it too (in Pasadena). Might’ve been an error. Watch Duty is still showing no warning in my region

I can think of no better justification for the expanded playoffs. When you let it be decided on the field, no one actually knows who the best teams in the league are

Astronomer here to try to put the mass in context

Current estimates of the mass in stars in the Milky Way are consistent with ~5e10 solar masses. The Phoenix A black hole is ~1e11 solar masses

So this black hole is about twice the mass of all of the stars in our Galaxy combined

I stand corrected! Mistook it for the Butterfly Nebula

Astronomer here — you’re correct. It’s stellar death, not birth. It’s a planetary nebula, which forms when a low-mass star not too different from the Sun sheds its outer layers at the end of its life

You’re still on this? Pat… it’s *more* football… I figured you would’ve come around by now 🏈🏈🏈

I feel that sentiment about life in space so much (galactic astronomer)

Whenever I’m asked about life on another planet, I honestly just lose interest in the conversation. It’s for the same reason — galaxies are cool in there own right, aliens or no aliens, and they have no bearing on my work

Fit to the department at 13/10 🎮🏎️

Yea even this year it feels like only a few teams are the real contenders. Nonetheless, it feels much less arbitrary. Which team gets to advance is decided on the field as opposed to people who we’re just told know things about football, even though a lot of them disagree anyway 🏈

As more of a football enjoyer and less of a die hard fan like yourself, I gotta disagree. This at least gets rid of the feeling that the #5 team (or #3 a few years prior) isn’t left out of a rightful place to fight for the title. If you’re #13, you weren’t going to win anyway. Lookin’ at you Bama

As soon as you pull a gun, you’re in a gun fight. Are you prepared for that?

Be transparent with your self defense instructors, and they can help you prepare to effectively use firearms in a defensive manner.

Stay safe friends

As a former grad TA, the act of grading was always fine in my book. It’s the quantity that gets you lol
