The distinctive pop of opening a champagne bottle is more than the cork coming free. The sudden release of high-pressure gas creates a freezing jet that’s initially supersonic. It even creates a Mach disk, like those seen in rocket exhaust. That supersonic flow can only be maintained, though, with a large enough pressure difference between the gas in the bottle and the atmosphere outside. Once the pressure drops below that critical point, the jet slows down and becomes subsonic. For more on champagne popping and its colorful plume, check out this previous post.

This Colorado supercell thunderstorm features an unusual twist. Notice the sawtooth-like protrusions along the outer cloud wall. These are Kelvin-Helmholtz waves, like these fair-weather clouds we’ve seen before, but instead of occurring vertically, they project horizontally! That implies that the invisible layer of air just outside the cloud wall is moving faster than the wall itself. That creates shear along the outer edge of the cloud wall and causes these waves to form. This is the first time I’ve ever seen this sort of thing. What an awesome photo! (Image credit: M.

NASA Spotlight: Brandon Rodriguez, Jet Propulsion Laboratory Education Specialist 

Brandon Rodriguez is an education specialist at our Jet Propulsion Laboratory (JPL) in Pasadena, California where he provides resources and training to K-12 schools across the Southwest. Working with a team at JPL, he develops content for classroom teachers, visits schools and speaks with students and trains future teachers to bring NASA into their classroom. When he’s not in the classroom, Brandon’s job takes him on research expeditions all around the world, studying our planet’s extreme environments.  

Fun fact: Brandon wakes up every morning to teach an 8 a.m. physics class at a charter school before heading to JPL and clocking in at his full time job. When asked why? He shared, “The truth is that I really feel so much better about my role knowing that we’re not ‘telling’ teachers what to do from our ivory tower. Instead, I can “share” with teachers what I know works not just in theory, but because I’m still there in the classroom doing it myself.” - Brandon Rodriguez

Brandon took time from exciting the next generation of explorers to answer some questions about his life and his career: 

What inspired you to work in the educational department at NASA?

I was over the moon when I got a call from NASA Education. I began my career as a research scientist, doing alternative energy work as a chemist. After seven years in the field, I began to feel as if I had a moral responsibility to bring access to science to a the next generation. To do so, I quit my job in science and became a high school science teacher. When NASA called, they asked me if I wanted a way to be both a scientist and an educator- how could I resist?

You were born in Venezuela and came to the U.S. when you were 12 years old. Can you tell us the story of why and how you came to America?

I haven’t been back to Venezuela since I was very young, which has been very difficult for me. Being an immigrant in the USA sometimes feels like you’re an outsider of both sides: I’m not truly Latin, nor am I an American. When I was young, I struggled with this in ways I couldn’t articulate, which manifested in a lot of anger and got me in quite a bit of trouble. Coming to California and working in schools that are not only primarily Latinx students, but also first generation Latinx has really helped me process that feeling, because it’s something I can share with those kids. What was once an alienating force has become a very effective tool for my teaching practice.

Does your job take you on any adventures outside of the classroom and if so, what have been your favorite endeavors?

I’m so fortunate that my role takes me all over the world and into environments that allow to me to continue to develop while still sharing my strengths with the education community. I visit schools all over California and the Southwest of the USA to bring professional development to teachers passionate about science. But this year, I was also able to join the Ocean Exploration Trust aboard the EV Nautilus as we explored the Pacific Remote Island National Marine Monument. We were at sea for 23 days, sailing from American Samoa to Hawaii, using submersible remotely operated vehicles to explore the ocean floor.

We collected coral and rock samples from places no one has ever explored before, and observed some amazing species of marine creatures along the way.

What keeps you motivated to go to work every day?

There’s no greater motivation than seeing the product of your hard work, and I get that everyday through students. I get to bring them NASA research that is “hot off the press” in ways that their textbooks never can. They see pictures not online or on worksheets, but from earlier that day as I walked through JPL. It is clearly that much more real and tangible to them when they can access it through their teacher and their community.

Do you have any tips for people struggling with their science and math classes? 

As someone who struggled- especially in college- I want people to know that what they struggle with isn’t science, it’s science classes. The world of research doesn’t have exams; it doesn’t have blanks to be filled in or facts to be memorized. Science is exploring the unknown. Yes, of course we need the tools to properly explore, and that usually means building a strong academic foundation. But it helped me to differentiate the end goal from the process: I was bad at science tests, but I wanted to someday be very good at science. I could persevere through the former if it got me to the latter.

If you could safely visit any planet, star, or solar system, where would you visit and what would you want to learn?

Europa, without a doubt. Imagine if we found even simple life once more in our solar system- and outside of the habitable zone, no less. What would this mean for finding life outside of our solar system as a result? We would surely need to conclude that our sky is filled with alien worlds looking back at us.

Is there a moment or project that you feel defined (or significantly impacted) your career up to today?

While I never worked closely with the mission, Insight was a really important project for me. It’s the first time while at JPL I was able to see the construction, launch and landing of a mission.

If you could name a spaceship, what would you name it?

For as long as I can remember, I’ve been watching and reading science fiction, and I continue to be amazed at how fiction informs reality. How long ago was it that in Star Trek, the crew would be handing around these futuristic computer tablets that decades later would become common iPads?  In their honor, I would be delighted if we named a ship Enterprise.

Thanks so much Brandon!

Peregrine falcons are built for speed. They’ve been clocked at more than 380 kilometers per hour when diving. This video from Deep Look examines some of the features that make these birds of prey so fast, from the shape of their eyes to the tubercles in their nostrils that help them breathe during high-pressure dives. 

Part of the falcon’s speed comes from its signature stoop, where it pulls in its wings to form a tight, streamlined shape. This reduces drag forces on the falcon, letting gravity pull it toward a high terminal velocity. But even with its wings extended, the falcon exudes speed and agility. Its wings form a sharp leading edge to cut through the air, with stiff, overlapping feathers that slice the flow. Compare this to the feathers of an owl, which specializes in silence rather than speed for catching its prey. (Video and image credit: Deep Look)

The dripping of a faucet and the break-up of a jet into droplets is universal. That means that the forces – the inertia of the fluid, the capillary forces governed by surface tension, and the viscous dissipation – balance in such a way that the initial conditions of the jet – its size, speed, etc. – don’t matter to the process of break-up. 

We’d expect that the inverse situation – the breakup of a gas into bubbles in a liquid – would be similarly universal, but it’s not. When unconfined bubbles pinch off, the way they do so is heavily influenced by initial conditions. But that changes, according to a new study, if you confine the gas to a liquid-filled tube before pinch-off. Confinement forces a different balance between viscous and capillary effects, one which effectively erases the initial conditions of the flow and restores universality to the pinch-off process.

Honestly, I think people seriously misinterpret Kylo Ren’s role as a villain, and not in a “he’s so misunderstood” Draco in leather pants kind of way.

He’s fascinating because he’s one of the few fictional villains that has some stuff in common with some of the real men who do dangerous and deadly things– he’s posturing, he feels persecuted, he’s explosive and uncontrolled, when he tries to look like a cool villain and give off that glib/‘badass’ vibe, it feels forced and awkward, it’s easy to laugh at him, but then he does something incredibly evil and reminds you that pathetic wannabes can be really scary dudes, too. He reminds me of school shooters, domestic abusers, extremely vitriolic alt-right internet trolls.

He doesn’t represent some grand vision or evil master plan like Voldemort. It’s all about outwardly channeling his inner turmoil and rage into self-aggrandizement, getting control over other people because he can’t control himself. He has thoughts, feelings, weaknesses, and at least a little bit of good in him. That doesn’t make him a misunderstood hero. The fact that he’s human and three dimensional and has people who care about him is part of what makes him more like the real evil that walks among us every day in the world. 

People are always saying, “Kylo Ren is such a pathetic villain, he’s a whiny emo trying to dress up like a cool bad guy,” but that is lampshaded IN-universe, that people think that’s lame, too, even Snoke. People keep thinking that Kylo was supposed to be a cool villain like Darth Vader and that the movies failed miserably in portraying him as one, but I don’t see how.

White dudes are just pissed that they don’t have any heroes to identify with in the new trilogy, but see a lot of themselves in Kylo Ben, so rather than admit that they can be (and usually are) the villains in other people’s stories, they feel the need to justify that the one character they identify with is actually a hero…

Huh, it’s almost like it kinda hurts to only be represented by villains in blockbuster movies or something…

[cspark]

Not all of us are sexist and racist cunts like you, dear. Plenty of us are completely comfortable and perfectly happy “identifying with” Finn for example. Hell, she’s not a hero, but one of my favourite characters in the movie was Phasma. She’s one of the coolest characters I’ve seen in Star Wars.

The only people that are impossible to identify with are Rey, who does not have a character or a personality, and Rose who is literally just pandering to the “fangirl” type, and an idiot who would rather save a few animals than save a bunch of kids, and then ruin Finn’s attempt to sacrifice himself to help the Rebellion.

One of my all time favorite parts of The Joy of Painting episodes is when Bob pulls what he calls a “bravery test”.

It goes like this: Bob’s just painted this gorgeous, simple landscape and it’s shaping up really well. But then suddenly he inhales sharply and says “it’s time for a bravery test.” He loads up his brush, and then goes right down the canvas, planting a giant tree right in the foreground.

He jokes about it, like “you worked so hard and now this crazy man wants a tree right in front of it”, but if you compare the painting before and after the “bravery test”, the newly added tree completely changes the focus and depth of the painting, and it always seems to make the rest of the painting deeper and richer for it.

I always thought that was really cool. And I’m pretty sure there’s some sort of life metaphor you could make from it, but I’ve worked all day and I’m too tired to go into all that.

Peggy Whitson just broke the U.S. record for cumulative days spent in space — and she isn’t set to return to Earth until September. Whitson is also the first woman to command the ISS, has done the most spacewalks as a female astronaut, is the first female chief of the astronaut office and the first woman to become a NASA science officer. She’s a legend.
