How does a star form? How does the universe form? And how can we use every bit of astronomical data to answer those questions? To find out, Dr. Charles Liu and co-host Allen Liu welcome astrostatistician Sabrina Berger, all the way from Melbourne, Australia, where she's currently pursuing her PhD. As always, though, we start off with the day's joyfully cool cosmic thing, the new radioastronomy photographs of Callisto, one of the moons of Jupiter, taken by ALMA. Sabrina talks about her own low-frequency radio astronomy research looking for hydrogen in the very early reionization period of the universe when the first galaxies were forming. (Be warned: we dive into the difficulties ionization poses for trying to discern these early processes, including a side trip into quantum mechanics, the hyperfine transition of neutral hydrogen at 21cm depicted on the plaque attached to the Pioneer spacecraft, and even the Cosmic Background Radiation.) You'll also hear how Sabrina is innovatively using GPS satellites to help calibrate large radioastronomy telescope arrays. For our first student question, Derek asks, “I heard that black holes can form right after the Big Bang, before stars do. How is that possible?” Sabrina describes these primordial black holes, and, although none have been confirmed yet, that there have been a number of papers published recently on the subject. In fact, one paper suggesting that the as-yet-undiscovered “Planet 9” could even be one of these primordial black holes. And then, finally, we get to the subject of astrostatistics, Sabrina's area of expertise. She explains that it allows you to harness every piece of information that you're observing in astronomy and to answer questions like “How does a star form?” or “How does the universe form?” You'll hear about huge data sets, the use of artificial intelligence, field level inferences… and the MCMC, or the Markov chain Monte Carlo used in statistics. (If you don't know what that is, you're not alone, and our own resident mathematician Allen helps Sabrina untangle the complexity with a cotton ball analogy that blew Chuck and Sabrina's collective minds!) For our next student question, Wally asks, “Why is redshift one like nine billion years ago, bur redshift two only two billion years before that, and redshift three only one billion years before that?” As Chuck says, “that's a little complicated,” just before he, Allen and Sabrina proceed to explain how we measure universal expansion, the passage of time, and the “stretching” of light. Our next conversation is one of the most controversial we've ever had and revolves around who Sabrina thinks makes the best espresso, Australia, Italy or a “Third Wave Coffee Shop” like we have here in the US. You'll hear about why there's an ISSpresso machine on the ISS – and how the Italian Space Agency invented a way to make an espresso in zero-g! Plus, you'll hear a little about the work-life balance in Australia and how wonderful astronomy down under is.

For astronauts on orbit, the Isspresso machine makes space a little bit more like home.

Astronauts in orbit often miss the comforts of home – from favorite foods to a steaming cup of coffee.

Samantha Cristoforetti is an Italian astronaut with the European Space Agency. She currently holds a few spaceflight records — including being the first person ever to brew an espresso in space. In 2014 and 2015, Cristoforetti spent 199 days aboard the International Space Station, where she performed a variety of scientific experiments. She studied generations of fruit flies to chart gene changes in relation to disease; she looked after Caenorhabditis elegans worms used in a Japanese-led experiment; and she tended to plants to study how they grow in microgravity. Cristoforetti was supposed to return to Earth in May 2015, but her stay on the ISS was extended to June after a cargo ship flying on a Russian Soyuz rocket failed to reach the space station. The delay extended Cristoforetti’s stay to 199 days, allowing her to collect the record for the longest single spaceflight by any female astronaut. (NASA astronaut Sunita Williams had previously held the record, at 195 days.) Cristoforetti’s record won’t last for long, though. NASA astronaut Peggy Whitson, who’s currently on the ISS, will soon surpass her. One of her records, however, will stay forever. Shortly before retuning to Earth, Cristoforetti used a coffee machine called ISSpresso to brew the first ever espresso in space. She then put on a Star Trek uniform top and used a special zero-gravity cup to sip it. Cristoforetti is not scheduled for another flight to the ISS for now, but she keeps working at the European Astronaut Centre in Cologne, Germany. Here, she works on new technologies that could one day be used for a future mission to the Moon. She’s “definitely” looking forward to going to space again though. “Hopefully it’ll be my turn again eventually,” she says. In the meantime, The Verge spoke with Cristoforetti about how she became an astronaut, what scientific experiments she performed on the ISS, and what happened to that famous space espresso machine.

Astronauts aboard the International Space Station may see 16 sunrises per day, but, they haven’t been able to wake up and smell the coffee – until now.

We went to a wedding and had some feelings about it, Jeremy got to fly a plane and did it totally wrong, how old is your selfie?, and drinking in space. As discussed on the show, we’d love to hear your submissions for “am I a jerk” and your listener feedback in general, you can find all the way’s to contact us at www.nerdoutloudpod.com! Updates on the Russian cargo craft discussed last week, enjoy a little taste of home in orbit with the ISSpresso, and drinking in space, it's harder than you think!
