Adler Planetarium's "Fabric of the Universe" display
May 14, 2018
Former KICP student (and current Harvard postdoc) Benedikt Diemer has collaborated with Isaac Facio from the Art Institute to create the Adler Planetarium's new "Fabric of the Universe" display.

In 2017, a big year for science, we learned from cosmic discoveries
January 11, 2018
Our Universe is unfathomably large - billions of years old, billions of light-years across, and filled with hundreds of billion of galaxies, each with hundreds of billions of stars and planets. It often is beyond the reach of our instruments and our minds. Nonetheless, driven by curiosity, each year we make discoveries that expand our view of it, surprise us and help us to understand our place within it.

The big event of 2017 was the collision of two neutron stars in a relatively nearby galaxy, 140 million light years away. Such events are commonplace, happening many times a day, yet this was one was special because for the first time, the National Science Foundation's Laser Interferometer Gravitational-wave Observatory (LIGO) detected tiny ripples in the fabric of space-time that the cataclysmic event created. LIGO alerted astronomers, and GW170817 became the most well-studied astrophysical event, viewed with radio, infrared, visible, x-ray and gamma-ray "eyes."

Here is but one thing we learned: most, if not all, of the heaviest elements in the periodic table, e.g., gold and platinum, were made by colliding neutron stars.

Of course, LIGO thrilled us in 2016 with its announcement that it had detected gravitational waves from colliding black holes; this past December, three American scientists (Barry Barish and Kip Thorne of Caltech, and Rainer Weiss of MIT) were honored with the Nobel Prize for that discovery.

Closer to home, in October we were surprised by the first interstellar asteroid ever seen. We are used to asteroids - debris left over from the formation of our solar system - visiting us. In fact, the PanSTARRS1 telescope on Haleakala that discovered Oumuamua (for "scout"), as it is now officially known, searches for near-Earth objects that are potentially Earth-threatening. Oumuamua is not bound to our sun; it flew in from the direction of the Lyra constellation, passed between Mercury and the sun, and flew out again in the direction of the Pegasus constellation.

As large as an aircraft carrier and similarly shaped, Oumuamua reminded us that we are connected to the rest of the cosmos. Our solar system likely has shed asteroids and even planets that have flown by other stars with planets, and four NASA spacecraft - Pioneers 10 and 11 and Voyagers 1 and 2 - have left our solar system. The Voyagers carry the Golden Record of sounds recorded from Earth that Carl Sagan and his team put together to introduce us to the larger Universe.

It has been more than 20 years since we discovered the first exoplanets (planets orbiting around other stars). NASA's Kepler satellite has been the exoplanet workhorse, having discovered more than 4,000 exoplanets and 600 planetary systems. Astronomers have identified around 10 exoplanets in the habitable zone. Last year's big news was the discovery of the TRAPPIST 1 system, seven terrestrial-like planets orbiting a red dwarf star about 40 light years away. Five of the seven planets are similar in size to Earth and three are in the habitable zone, the sweet spot where liquid water - and hopefully life - can exist. We are well on our way to answering a very big question: Are we alone?

Moving to the far reaches of the Universe, the most distant quasar seen yet was discovered last year. The light we see began the journey to us when the Universe was only about 700 million years old. It presents us with a mystery: How did the billion-solar-mass black hole that powers this quasar form so early in the history of the Universe? (All galaxies, including our Milky Way, have massive black holes at their centers and go through an early "quasar phase" when their black holes shine brightly because of infalling matter.) LIGO and other gravitational-wave detectors coming on line in the future should shed light on this question.

While the great American eclipse of 2017 was not a surprise and did not lead to any startling discoveries, millions of Americans including me - were awed by it as the path of totality traversed the United States from Oregon to Georgia. In this amazing natural phenomenon, the moon nicely fits over the sun and blocks its light, allowing us to look directly at the sun without being blinded and view its - beautiful corona.

The corona of the sun is much hotter (millions of degrees) and wispier than its surface, extending many solar radii beyond the disk of the sun. The corona is responsible for much of the sun's activity that impacts our planet, including solar flares and coronal mass ejections, and how the corona works is still a mystery. Later this year, NASA will launch the Parker Solar Probe, which will orbit the sun on a highly elliptical path that will take it inside the sun's corona - really! - more than 20 times to make measurements that could solve some of mysteries of the corona.

Science is now a global activity that the United States no longer dominates. But as these discoveries illustrate, we continue to lead. Our success has involved three critical elements: thinking bold, throwing deep and sticking with it.

The LIGO Nobel Laureates were bold enough to think that you could detect a change in distance of one-thousandth the size of a proton between two mirrors separated by four kilometers. The NSF threw deep when it invested close to $1 billion over 25 years to build LIGO. And NASA stuck with it when Hubble had initial mirror problems, and more recently when it found a work-around to keep Kepler producing science after two gyros failed at the end of its four-year planned mission.

Certainly, cosmic discoveries help us to understand our place in the Universe, but they also inspire and awe us, young and old.

Gravitational Waves Events
October 13, 2017
I am pleased to let you know about three special, late-breaking news events that will take place on campus this coming Monday and Tuesday.

FIRST, On Monday, October 16th at 09:00 CDT, the National Science Foundation will host a press briefing at the National Press Club in Washington, D.C., bringing together scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo collaborations, as well as representatives from some 70 observatories. This will be live-streamed and we will set up a live viewing with some of the involved University of Chicago scientists in the lobby of ERC, as well as in room 201 of the Physics Research Center.

The press briefing will begin with an overview of new findings from LIGO, Virgo and partners that span the globe, followed by details from telescopes that work with the LIGO and Virgo collaborations to study extreme events in the cosmos.

The discovery of gravitational-waves by LIGO opened a new window to the Universe and involved several UChicago scientists. This year's Nobel Prize in Physics recognized three scientists for their contributions to the LIGO detector and the first observation of gravitational waves.

SECOND, there will be a special, more technical colloquium on the topic Monday, October 16th at 4:00 p.m. CDT in ERC 161, featuring University scientists Daniel Holz and Joshua Frieman, followed by discussion and comments by Holz, Frieman, Hubble Fellow Dan Scolnic, University Professor Wendy Freedman, and students and postdocs involved in the new findings. Following the discussion there will be a reception in the atrium.

THIRD, there will be an event on Tuesday, October 17th from 5:00 - 7:00 p.m. in Kersten Physics Teaching Center (KPTC 120), consisting of about 5 short presentations by graduate students and postdocs and a Q&A/discussion. This will be geared more to the general public and university undergraduates.

I encourage you to join us for any of these special gatherings.

Eclipse reflects sun's historic power
August 16, 2017
Michael Turner, KICP director
Eclipses have fascinated people since the earliest days of recorded history.

These rare astronomical events have helped explain the world around us -- from ancient Mesopotamia, where they were believed to foretell the deaths of kings, all the way to the 20th century, when they helped prove Einstein's theory of general relativity.

Such interest hasn't dimmed. People across the United States will have an opportunity on Aug. 21 to witness the first total solar eclipse from coast to coast in 99 years. UChicago faculty and students are among the hordes of enthusiasts traveling across the country toward the area of "totality," the 70-mile-wide stripe stretching from Oregon to South Carolina in which the moon will fully block the sun.

Ahead of this historic event, UChicago News asked scholars in fields ranging from theoretical cosmology to Islamic studies to discuss eclipses and their power.

The eclipse that proved Einstein was right
Michael Turner, Bruce V. & Diana M. Rauner Distinguished Service Professor in Physics

"Astronomers have learned a lot from eclipses, including one in 1919 that proved Einstein was right.

At the time, only a handful of people were aware of general relativity; Sir Arthur Eddington was one of them. He led an eclipse expedition into the Atlantic to find out whether gravity would bend starlight, as predicted by general relativity. What you want to do is look at stars very close to the sun, and see whether the light coming toward us is bent by the sun's gravity. With the moon blocking the sun, you can get that measurement, and it was exactly what Einstein predicted. The scientific community was agog. It instantly put general relativity on the map, and made Einstein a rockstar.

We're still learning things from eclipses. One thing people will study during this event is the corona of the sun, which is the glowing aura of gases that surrounds the sun. There are still things we don't understand about it -- such as exactly why it actually burns hundreds of times hotter than the surface of the sun itself.

A few years from now, NASA will launch a probe named after UChicago's own Eugene Parker that will explore the sun's corona -- closer than any probe has ever come to the sun."Learn more >>

Jason Henning is a post-doctorate fellow at the Kavli Institute for Cosmological Physics at the University of Chicago. He's been to the South Pole three times, working on the university's 10-meter telescope there.

On Tuesday morning, he found himself advancing science in a place it doesn't frequently go: sitting on a too small chair in a basement classroom with the lights dimmed.

"Who's ready for an eclipse?" he asked a group of 4- and 5-year-olds sitting around a table at Bright Horizons at Lakeview, a preschool.

The youngsters didn't exactly squeal "Yes!" in unison, but they at least cast their attention in his general direction. Henning proceeded, using a small model Earth, moon and, as a light source, a lamp with a dinosaur base.

"Does anybody know how you make night and day?" asked Henning. "Does anybody remember?"Learn more >>

Space Explorers Program Evaluation and Experiments Featured at the 2017 National Science Teachers Association (NSTA) Meeting Los Angeles, CA
June 14, 2017
Randall H. Landsberg presented "Space Explorers: 25 Years of Inner-city Students Out of School Time Explorations" as part of the "mission possible" thread at the NSTA national conference. The talk included data on how students in the program are out preforming their peers and exemplar, hands-on, inquiry based experiments. The experiments both involved measurements but in very different realms: the size of the universe and the response rates of rods compared to cones in the human eye.


Space Explorers Compared to Chicago Public Schools.


Undergraduate First-Year STEM Majors National Data Comparison.

Presentation Abstract:
Since 1991 Space Explorers has offered first generation, low income inner-city students and university astrophysics researchers the opportunity to explore together (with over one hundred contact hours a year). An external evaluation probed the impacts of this program on the hundreds of students and instructors involved. We will examine the evaluation findings, which map well to the recent NRC study on out of school time programs. We will also explore some of our favorite lab activities, hear about taking students to Yerkes Observatory for residential science institutes, and discuss best practices for university and community based organization partnerships. Take home new ideas for student labs and partnerships.

Deflategate: Cold Wet Footballs, Ideal Gas Laws and Accusations of Cheating
February 8, 2017
Just in time for Super Bowl LI, students in the Space Explorers Program examined the physics and media frenzy of Deflategate. During the 2015 AFC championship game, NFL officials discovered that the pressure in several footballs used by the New England Patriots had decreased below permissible levels. This sparked a national controversy known as "Deflategate". The NFL (as well as many enemies the four-time Super Bowl champions Patriots had made in the football world) argued that the pressure drop could only be caused by cheating, especially because Tom Brady favors underinflated balls. (note: each team controls 12 footballs used when they are on offense mandated to be between 12.5 and 13.5 psi ). Patriots' fans argued that the drop was caused either by well known laws of physics, or by an elaborate NFL conspiracy.

Twenty-eight (28) high school students in KICP's Space Explorers program put these arguments to the test. Over the course of two weeks, students critically evaluated over a dozen arguments made by both sides, ranging from court documents, to college lectures, to tweets. Despite the strong opinions, contradictory claims, and often factually incorrect information found in these arguments, the Space Explorers managed to identify the critical questions that needed to be resolved to determine if Deflategate could be caused by purely innocuous physics and designed an experiment to address them. Their experiment revolved around measuring the effect that wetness had on the rate at which cold footballs warm up and increase in pressure.

To date their results are inconclusive. One trial found nothing suspicious about the pressure drop, and a second could not explain the low pressures in the Patriots' footballs. The Space Explorers themselves are split down the middle about how to interpret their results and will debate the best way to resolve this difference at the pre-Super Bowl Saturday class.

Chicago high school students visit to experience "A day in the life of a scientist"
November 15, 2016
Professor Freedman talks about life as a scientist with the students.
KICP Senior Member Wendy Freedman has been invited to be the 2016-2017 Robert A. Pritzker Visiting Scientist in Residence at Chicago's Francis W. Parker School. The program aims to expand science education opportunities at Parker and foster an ongoing dialogue among students and teachers about current issues in science.

As part of her activities, Professor Freedman recently arranged for students to visit the Eckhardt Research Center for a discussion and tour of the KICP and Astronomy & Astrophysics labs and the Pritzker Nanofabrication Facility. Students visited the PNF and the KICP labs of Professor Erik Shirokoff (where Associate Fellow Peter Barry described the lab equipment and activities), and gathered in Professor Stephan Meyer's lab to see a camera that will be used in a balloon-borne experiment to detect cosmic ray showers. Professors Meyer and Freedman also spoke to students about various aspects of their research and their lives as scientists.

Congratulations to Matthew Richardson, PFC Fisk-Vanderbilt Bridge Program participant!
October 10, 2016
Dr. Matthew Richardson
Congratulations to Matthew Richardson for successfully defending his Ph.D. dissertation on "Constraining Microwave Emission from Extensive Air Showers via the MIDAS Experiment".

"Through a careful analysis of data collected by the MIDAS detector installed at the Pierre Auger Observatory, Matt has established the best limits on microwave emission from Extensive Air Showers induced in the atmosphere by Ultra-High Energy Cosmic Rays (UHECR). His results, an improvement by more than one order of magnitude over previously published limits, place strong constraints on the prospects of this technique for UHECR detection."

Matt has received a position of Postdoctoral Research Scientist at the Planetary Science Institute.

2016 Yerkes Summer Institute: Spy vs. Spy
August 16, 2016
Instructors: Camille Avestruz, Zoheyr Doctor, Gourav Khullar, Richard G. Kron, Randall H. Landsberg, James Lasker, Phil Mansfield, Sam Passaglia, Rebecca Pierce, Jason Poh.

The 2016 Yerkes Summer Institute (YSI) was filled with secrecy, deception, and espionage. At YSI, high school students in the Space Explorers program played the role of 20th-Century spies to handle secret information: revealing, concealing and distorting information. Through three day-long lab activities, the students explored connections between spying and science. In the "Secret Photos" lab, they studied angular size, resolution, and the film-development process in order to effectively gather information on "enemy operatives" using 35 mm cameras. In the "Radio Beams" lab, students designed, built, and tested a system to transmit audio via an amplitude-modulated (AM) laser, which allowed them to secretly communicate across long distances. Lastly, techniques to securely communicate were examined in the "Codes and Ciphers" lab, which also served as an introduction to modern cryptography. After cycling through these three day labs, the students broke into three new groups and took one of the labs a step further: one group doctored photographs to spread false information, another built AM radio transmitters and receivers, and the last created treasure hunts using codes and ciphers for the clues. Nighttime activities included: observations with the Yerkes telescopes, astrophotography, explorations of the constellations which focused on what current research can tell us about them (e.g. most know exoplanets were found by Kepler in the constellation Cygnus); and bad weather activities that included examinations of the veracity of viral internet photos, and stories of famous spies. The week's spy-themed activities not only introduced the students to the importance of privacy in the digital age, but also to the concepts and skills that are integral to any modern STEM career.

Physics in your future: Brittany Kamai
May 2, 2016
Brittany Kamai, KICP graduate student
When Brittany Kamai took her first astronomy class as a freshman at the University of Hawaii, her professor told her that we can only see about 4% of the stuff in the universe. The rest is made of mysterious substances called dark matter and dark energy. "I found it fascinating that in the entire textbook for our class, there was barely a paragraph about this crazy thing," she recalls. Inspired, Brittany decided to study physics. During the summer before her last year of college, she accepted an opportunity to do research at the Institute for Astronomy at the University of Hawaii. She was hooked. Brittany went on to join the Fisk-Vanderbilt Master's-to-PhD Bridge Program, a two-year program designed to help students with limited undergraduate research experience. She is now in the PhD program at Vanderbilt University in Tennessee. But she actually spends most of her time in Chicago, because her research is based at Fermilab, a large U.S. Department of Energy research facility in northern Illinois. Brittany is building what she calls "the world's most precise ruler" - also called a "holometer." She and her colleagues hope to use intersecting laser beams to measure space itself very precisely, so they can look for tiny differences between what they measure and what Einstein's theory of general relativity predicts about it. Brittany and her colleagues are now testing the machine and making it as accurate as possible. They have just begun to run their experiment and hope to have results very soon. She will soon finish graduate school, but plans to continue pursuing experimental research in astrophysics. She likes the variety of work she gets to do. "Sometimes it's nice to say OK, I don't have to go into the lab, I can be behind my computer," she says. "And sometimes it's like, I'm sick of this - let me go back in lab! I enjoy that." When Brittany's not doing science, she's often talking about it, and encouraging young people - especially girls - to pursue it. She sees this as an important part of her job. In the past five years, she has shared her enthusiasm for science at museums, at middle schools and high schools, and even at senior centers. "You talk to people who are 50-plus, they get super-jazzed about it, they tell their kids, their grandkids," she says. "And it's like yes! This is how you get people excited about science."Learn more >>

Michael Turner discusses LIGO & the detection of gravity waves
April 12, 2016
Michael Turner is best known for having coined the term "dark energy" in 1998. A theoretical cosmologist at the University of Chicago, Turner has dedicated his career to researching the Big Bang, dark energy and dark matter. He wrote his Ph.D. thesis on gravitational waves - back in 1978 - and nearly four decades later had a bird's eye view of their recent discovery. Turner was assistant director of the National Science Foundation (NSF), which funded the development of LIGO, which stand for the Laser Interferometer Gravitational-Wave Observatory. This large-scale physics experiment and observatory, which was led by researchers at MIT and CalTech, discovered, on September 15th, 2015, the existence of gravitational waves via a chirping noise signaling the collision of two black holes a billion light-years away. The scientists announced their discovery on February 11th, 2016. In this episode, Turner interprets this momentous finding, and talks about some of the big player scientists who worked on LIGO.Learn more >>

TCN Panel on Space: Wendy Freedman and Angela Olinto
April 1, 2016

If you can't see it, you won't be it. Future women leaders need examples.

In that spirit, The Chicago Network recently gathered an audience of young women and Network members to hear from four of the world’s foremost astrophysicists - all Network members - to demonstrate the tremendous impact women are making in STEM and the possibilities that lie ahead for the next generation. Young scientists left feeling energized by the program moderated by Adler Planetarium President and CEO Michelle Larson, and ready to take on the challenge of studying even the most profound universal mysteries.

According to Michelle, panelists Wendy Freedman, Vicky Kalogera, and Angela Olinto illustrate more than an exploration of the universe in this program, they demonstrate what it is to discover your own individual capacity for leadership:

The panelists in this program take us on a journey through the Universe, and provide inspiration through their life stories. You will hear about measuring the age and size of the Universe, probing current mysteries like dark energy and dark matter, and opening a new observational era with the discovery of gravitational waves. As you take this journey, also listen for the words passion, people, and perseverance - all play an important role in their success. Finally, listen for the number of times you hear these women say "I led" or "I lead." These panelists are amazing leaders, and each of them is certain you could be too. What a great endorsement of your potential - run with it!

Life Long Learning program
March 9, 2016
This spring, graduate students, postdocs, and Professors from KICP and the Department of Astronomy & Astrophysics will present at least 19 lectures to older adults throughout Chicago, as part of the Life Long Learning program associated with Daniel Grin's NSF Astronomy and Astrophysics Postdoctoral Fellowship. Adults past retirement age make up an increasingly large demographic, and continued cognitive/social engagement are crucial for healthy aging. We'll bring basic and cutting-edge content in astrophysics to interested older adults at city senior centers, retirement homes, and public libraries. We are always looking for more presenters to reach wider audiences. To conclude this year's program, we will bring hundreds of older adults to the Adler Planetarium in June free of charge.
