Cosmos, Swiftly: Remembering the Genius of Vera Rubin
Alycia Weinberger: When I initially went there in the early 1990s, there was a bathroom in a heated, comfy, computer system-driven observing space and it did not have any plate on the door to say no matter whether it was for males or girls. But I currently knew this story about Vera and the bathrooms and so I went searching for the bathroom in query [laughs] in the observatory.
Tulika Bose: You are listening to Alycia Weinberger—an observational astronomer in the Earth and Planets Laboratory at the Carnegie Institution for Science—talk about famed astronomer Vera Rubin.
Clara Moskowitz: And like so a lot of other stories about girls and science, this story also frustratingly includes a bathroom. But initially, let’s take you back in time.

Bose: It is 1965. The Sound of Music premieres.

Moskowitz: Martin Luther King, Jr. leads 25,000 civil rights activists to a courthouse in Selma, Alabama.

Bose: Astronaut Ed White tends to make the initially US space stroll.

Moskowitz: And a female astronomer who would go on to modify the course of cosmology is initially turned down from going to the Palomar observatory—because they do not have the correct “facilities.” In other words—
Weinberger: They could not give her observing time. And she discovered somehow that the facilities in query had been that there was only one particular bathroom in the dome of the telescope and it had a sign on the door that mentioned, “men.”
Bose: But Vera located a way to, let’s say— skirt this concern.
Weinberger: Some time later, she went for her initially observing run at Palomar. And so she produced a small female stick figure with a skirt out of tape and place it on the bathroom door. And she mentioned each and every time subsequently that she would go, the small stick figure had been removed, but she would remake it, place it back on the door.
Bose: A bathroom is far from the only red tape that Vera Rubin will face all through her decades-extended profession.
Clara: But this devoted astronomer—who began out at fourteen years old with nothing at all but a cardboard telescope—would go on to uncover compelling proof of dark matter, which we now think tends to make up most of the matter in the universe.
Bose: I’m Tulika Bose, the senior multimedia editor at Scientific American.
Clara: And I’m Clara Moskowitz, senior editor for space and physics at Scientific American. And you are listening to Cosmos, Swiftly.
Bose: So it is the final day of women’s history month, but we never ever require an excuse to speak about Vera Rubin. Clara, inform me about when you initially discovered about her.
Moskowitz: I was one particular of a couple of female physics majors at Wesleyan University. And Vera Rubin was this well-known figure, each simply because she located proof for dark matter–one of the greatest mysteries in science–and simply because she actually paved the way for girls astronomers soon after her. She’s the classic case of who the Nobels robbed.
Bose: Why do you believe she never ever received a Nobel?
Moskowitz: Certainly simply because she’s a lady. Ha. I imply, some scientists have recommended that also a lot of other researchers helped place with each other the information on dark matter to reward just her, but these type of quibbles could apply to every person who’s ever won the prize. It is broadly believed to be simply because of gender bias.
Bose: We can speak about the Nobels—and particularly the reality that physics has the widest gender ratio in any of the Nobels at all.
Moskowitz: But we can also speak about Vera Rubin.
Bose: A couple of weeks ago, I went to the Carnegie Institute of Science (formerly the Carnegie Institute of Terrestrial Magnetism) to film an outstanding group functioning on exoplanets with the James Webb Space Telescope.
But what loomed huge more than the institute was the guiding hand of Vera Rubin.
Moskowitz: What did you locate?
Bose: Not only did we get to see some of the instruments that she made use of to measure galaxies, but some of the persons we had been speaking to about exoplanets at the institute had when identified her. And they had a lot of memories.
Johanna Teske: Vera Rubin holds a particular location for a lot of astronomers, I believe. I knew her. I was an intern right here at Carnegie, when I was a college student at American University.
Bose: That is Johanna Teske. She’s not precisely an intern anymore—she’s a employees scientist there and her investigation focuses on the diversity of exoplanet compositions. She’s also co-major a enormous exoplanet project using the James Webb Space Telescope.
Bose: Yeah. It turns out that Vera Rubin has a extended history in mentoring girls in this specific division at Carnegie.
Teske: She actually was portion of attempting to push astronomy to be a lot more inclusive, um, and make a lot more possibilities for girls in science and astronomy.
Bose: Vera wasn’t all business enterprise, though—at least according to Alycia Weinberger who we heard at the beginning—Johanna’s former mentor and a employees scientist who also functions on exoplanets.
Weinberger: She had a huge collection of spectrum like clothes and jewelry that she enjoyed wearing. And in specific, I remember…and so basically a rainbow, correct? A rainbow necklace of beads that she had. She also had a rainbow toy on her table at property. She enjoyed rainbow socks….
Bose: And that is simply because Vera worked to take spectra.
Weinberger: That is exactly where we break up the element light from an astronomical object into its element colors, which give us a lot of data about how that object is moving and what it is composed of.
Bose: Clara, can you break this down the Doppler impact a small bit for us non-physics plebs?
Moskowitz: Searching at the colors of light coming from a thing in space can inform us how quick a thing is going, simply because as an object moves away from us, its light waves spread out, lowering their frequency and lengthening their wavelength, producing issues appear redder.
Bose: To do this, Vera also worked with these new instruments at Carnegie, along with Kent Ford. One particular of these instruments, now in a Smithsonian collection of “101 Instruments That Produced America” is referred to as an image tube spectrograph, also referred to as a spectrometer.
Moskowitz: Fundamentally, it was this instrument that was attached to numerous huge telescopes in the 1970’s to analyze spiral galaxies. And it permitted these astronomers to analyze galaxies that had been farther away.
Bose: Particularly the Andromeda galaxy, which was about two.five million light years away. But she and Kent located a thing surprising about all of this.
Weinberger: Extremely meticulously and taking benefit of new instrumentation that was created right here, was in a position to measure how quick stars in the outer components of galaxies had been rotating about their centers. And more than a lot of years showed that most galaxies showed these what are referred to as flat rotation curves.
Moskowitz: A flat curve suggests that stars on the outdoors of the galaxy are moving just as quick as stars on the inside, which is not basically what you’d count on at all. Simple Newtonian physics suggests that basically, as you move toward the outskirts, the stars would start out to slow down as they orbit the center of the galaxy.
When Rubin began seeing that these outdoors stars had been nevertheless speeding about, it actually presented the initially sturdy proof that there should be a lot of hidden mass extending way out beyond the stars we can see with our eyes.
Bose: Let’s be clear about a thing. It took Vera years of persistence for her colleagues to recognize this. She offered flat curve soon after flat curve for decades, till the information she made couldn’t be denied.
Moskowitz: She didn’t win the Nobel, which persons noticed.
Teske: I was so angry, that she hadn’t had that, you know, gotten a Nobel Prize in the time that she was alive. But that is not the finish all be all. And there are lots of other approaches to honor persons.
Bose: Clara, let’s speak about the Vera Rubin Observatory, which is scheduled to be completed in 2024.
Moskowitz: This is a major telescope that is becoming constructed correct now in Chile, and when it turns on it is going to photograph the whole sky each and every couple of nights to make up these actually detailed maps of the universe. And one particular of its major targets is to investigate the nature of the dark matter that Vera Rubin helped uncover.
Bose: It is also the initially observatory to be named in honor of a female astronomer. And even though it is unfortunate that Rubin never ever won the Nobel….
Moskowitz: ….she’s won the people’s option Nobel. If that is a factor.
Bose: I’ll leave you with a thing that Alycia mentioned.
Weinberg: She had a tremendous influence on the way I believed about girls in science and the capabilities of girls. She mentioned, there is no science that can be accomplished by a man that can not be accomplished by a lady.
Moskowitz: And hopefully one particular day it will not be so notable if girls win Nobel prizes, simply because they’ll be performing it all the time. Since by the way, we nevertheless do not know what dark matter is. And if somebody ever figures that out, it is a Nobel Prize for confident.Cosmos, Swiftly is made by myself, Tulika Bose, Kelso Harper, Jeff DelViscio, and Lee Billings.
