This right here is a *masterpiece* of processing by none other than Jason Major: Rhea and Epithemeus in front of Saturn 😍

Although you're probably already like "duh it's gorgeous, yeah it's a masterpiece!", it's more than that: those are moons, and moons are in constant motion. Color images are produced by combining images taken in the red, green, and blue filters.
Each image is taken at slightly different times, so the moons will be in different positions in each shot. If you just superimpose them, you'll get something that doesn't have sharp edges like you see here.
This requires the expertise that I admire in images taken by people who've inspired me to start doing this, like @JPMajor. I was never able to get it right. But I'll keep trying, and continue to admire the images like these that experts like Jason process!
Also, *Epimetheus πŸ˜‘
*not taken, but processed.

Any fellow Jewslims here? As in, a parent who's a Jew, and one who's Muslim (regardless of your actual faith/lack thereof)? I've been told I'm weird and it doesn't feel good. RT if you think I'm not weird, and (pls) like/comment if you're a Jewslim too. I know I'm not alone πŸ•ŒπŸ•
Disclaimer: I'm not religious like AT ALL. I love bacon and there's nothing I can do to change that. (Although kosher/halal meat actually does taste better, but πŸ– is forbidden for Jews and Muslims but, like, BACON HELLO πŸ€·πŸ»β€β™€οΈ)
I don't like being told I'm weird anymore. I used to be ok with it when I was younger, but it's wrong, it's based on this stupid idea that Jews and Muslims can't live together. I'm living proof that it's wrong. Anyone out there like me please stand up and tell me I'm not alone πŸ’–

Academics! Do you know of any organizations that offer travel grants to grad students to go to a conference to present their work? Please let me know if you do, I *really* want to go to this conference! (It's IPA 2018, Interplay between Particle and Astroparticle Physics, btw)
It's like the perfect conference for me to gear up for PHENO, my ultimate.
Hi @APSphysics, I'm a member! Could you help direct me to the right place to apply for a travel grant? I heard about IPA 2018 after the deadline to apply for grants at my school. IPA is right up my alley, and I'd love to attend and present my research! Any help is appreciated!

"Jo, let's go."
"Nah I think I'm gonna wait till I quantum tunnel through the car door."
"Jo, the probability of that happening is e^-10^35, you'd have to wait longer than the age of the Universe for it to happen!"
Progress: only a few Universe ages left, but Jo will never know.
The things you run into in the parking lot of a Ralphs in Los Angeles. Sigh.
And, for those who are interested, here's a thread I turned into a moment on the probability of a human being quantum tunneling through a wall:…

One reviewer decimated me for not having publications when I applied for @NSF GRFP. Yesterday, 2.5 hours w/my team and we've divided up writing of my first paper. Plus *another* paper in the works. I'll have two as a 2nd year grad student. Take that! πŸ‘Š
To be clear: I had *just begun* grad school when I applied for the fellowship. So, yeah, they pummeled me for not having a paper as a first year grad student, although I clearly outlined the research that's coming together into a publication (coming soon to a journal near you πŸ˜€)
So, I got rejected, but got an honorable mention from the @NSF, because one reviewer sucked. And guess what? I'm still gonna science and show exactly why I was one of the people they should've funded! πŸ™‚ There's my rejection story =)

620 ly away, a planet 3x the mass & 2x the diameter of Jupiter orbits so close to its star that temps reach 4600 K. That's ~1000 K higher than most stars! This heat allowed astronomers to, for the 1st time, find atomic iron & titanium in its atmosphere.…
(GIF from video in the link above, which was uploaded by Vanderbilt University)
Titanium has been detected in atmospheres of exoplanets, but bc they aren't as hot, never in its atomic form. Exoplanets with temps over 2000 K are called "Ultrahot Jupiters", this one is by far the hottest. Detecting atomic Titanium and Iron are a really big deal.

This should *never* have to happen to a PhD student. Quals are the most stressful part of grad, and mean shit. If you want to make sure your students have their core courses down, no test do this. Make core courses adequate, and students will have them down w/o needless stress.
The only reason a PhD student should be prevented from obtaining their PhD is for failing to defend appropriately or not having the minimum GPA required. But quals on top of that? Bullshit. Once I'm done my courses I'm coming down and advocating for their removal *hard*.
Students don't go to grad school to relive PGRE nonsense, we go for research, papers, learn advanced physics that'll help w/research. We're expected to take courses, do research, crank papers, *and* quals? I've never lived anything more stressful. Won't stop till they're removed.
