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

It was just shown on perhaps the grandest scale possible that the SEC is not any better at football than other conferences. If anything, theyโ€™re low caliber #CFP #CFBPlayoff

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

None of the 1-4 seeds made it to the final four of the #CFP. In the old system, they wouldโ€™ve been simply placed there

When you let them play it out on the field, no one actually knows whoโ€™s going to go all the way

I can think of no better justification for the expanded playoff system

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

NGC 6302 - Wikipedia

I stand corrected! Mistook it for the Butterfly Nebula

Astronomer here โ€” youโ€™re correct. Itโ€™s stellar death, not birth. Itโ€™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

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

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

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 weโ€™re just told know things about football, even though a lot of them disagree anyway ๐Ÿˆ

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) isnโ€™t left out of a rightful place to fight for the title. If youโ€™re #13, you werenโ€™t going to win anyway. Lookinโ€™ at you Bama

This thread is for authors of scientific papers, and particularly astronomers. I struggled a bit with how explicit I had to be, but I think including a name is important. We (meaning all the major journals) have rules against submitting a manuscript to more than one journal at a time. 1/6

Since I recently joined Bluesky, people should be warned that I have a life goal of making my followers as hungry as possible

So in that spirit, I present last nightโ€™s braised beef ragu with pasta. Homemade from scratch ๐Ÿ˜‹ whoโ€™s hungry?

As soon as you pull a gun, youโ€™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

I sympathize with this desire. However, for those who would like to defend themselves with a firearm, please also take self defense training.

Especially in close quarters, your attacker may take it and use it on you. This is actually an *extremely* common source of gun injuries.
