CIERA Fifth Annual Public Lecture

"Old Moon, New Moon"

Watch the CIERA Fourth Annual Public Lecture

Dr. Maria Zuber

(E.A. Griswold Professor of Geophysics, Vice President for Research at MIT)

April 3 rd, 2014

4:00pm at Tech Ryan Auditorium

This Event is FREE to the Public.

ABSTRACT: Since before the emergence of the first single-celled organisms in primordial seas, the Moon has illuminated the night sky. The Moon holds a strong cultural connection to all of us, at once our nearest neighbor and far enough away so that landing on its surface represented the pinnacle of human technical achievement. Study of the Moon informs our understanding of how the rocky planets, including Earth, formed and developed. This presentation will discuss our evolving understanding of the Moon from the earliest observations through GRAIL, a dual-spacecraft mission that mapped the lunar interior from crust to core.

BIOGRAPHY: Dr. Maria Zuber is the E.A. Griswold Professor of Geophysics (in the Department of Earth, Atmospheric, and Planetary Sciences) and Vice President of Research at the Massachusetts Institute of Technology in Cambridge, Massachusetts. Dr. Zuber has led the development of a wide range of instruments that have ventured to Mars, Mercury, and the Moon on a variety of NASA missions. Her interests lie in understanding the structure and tectonics of solid planets in our inner solar system through the use of laser and radio tracking experiments on spacecraft. In addition, her group is currently developing an instrument to search for DNA and RNA on the surface of Mars.

Among her many honors, she was appointed by President Obama to the National Science Board, was Chair of the MIT Department of Earth, Atmospheric, and Planetary Sciences from 2003 to 2011 (and was the first woman to lead a science department at MIT), was named one of America's Best Leaders by U.S. News and World Report in 2012, was listed as one of the 50 Most Important Women in Science by Discover Magazine in 2002, and has won numerous awards including: the Harry H. Hess Medal of the American Geophysical Union, MIT's James R. Killian Jr. Faculty Award, a NASA Distinguished Service Medal, and many NASA Achievement awards for her work on nine different NASA missions. She has held distinguished lectureships at the Niels Bohr Institute, Harvard University, Cornell University, Stanford University, and at the American Institute of Aeronautics and Astronautics, among many others.

Dr. John M. Grunsfeld (NASA)

February 19th, 2013
4:00pm at
Tech Ryan Auditorium

This Event is FREE to the Public.

ABSTRACT: This is a time of accomplishment and opportunity for NASA Astrophysics. We have 13 space-based observatories spanning the electromagnetic spectrum that are studying the universe, the physics of the cosmos, cosmic origins, and searching for exoplanets. NASA's next great astrophysics observatory, the James Webb Space Telescope, is on track to launch in 2018 and will address many of the outstanding issues of modern astronomy related to the 'Early Universe' and is expected to yield scientific breakthroughs as did its predecessor, the Hubble Space Telescope. This presentation will explore the latest discoveries and NASA’s plans for the future.

BIOGRAPHY: John Grunsfeld is the Associate Administrator for the Science Mission Directorate at NASA Headquarters in Washington, D.C. He previously served as the Deputy Director of the Space Telescope Science Institute in Baltimore, managing the science program for the Hubble Space Telescope and the forthcoming James Webb Space Telescope. Grunsfeld’s background includes research in high energy astrophysics, cosmic ray physics and in the emerging field of exoplanet studies with specific interest in future astronomical instrumentation.

Grunsfeld joined NASA's Astronaut Office in 1992. He is veteran of five space shuttle flights, and visited Hubble three times during these missions. He also performed eight spacewalks to service and upgrade the observatory. He logged more than 58 days in space on his shuttle missions, including 58 hours and 30 minutes of spacewalk time. Grunsfeld first flew to space aboard Endeavour in March 1995 on a mission that studied the far ultraviolet spectra of faint astronomical objects using the Astro-2 Observatory. His second flight was aboard Atlantis in January 1997. The mission docked with the Russian space station Mir, exchanged U.S. astronauts living aboard the outpost, and performed scientific research using the Biorack payload. He also flew on Discovery in December 1999, Columbia in March 2002 and Atlantis in May 2009. This last flight successfully serviced and upgraded the Hubble Space Telescope, during which he was lead spacewalker for Hubble servicing activities. In 2004 and 2005, he served as the commander and science officer on the backup crew for Expedition 13 to the International Space Station.

Grunsfeld graduated from the Massachusetts Institute of Technology in 1980 with a bachelor's degree in physics. He subsequently earned a master's degree and, in 1988, a doctorate in physics from the University of Chicago using a cosmic ray experiment on space shuttle Challenger for his doctoral thesis. From Chicago, he joined the faculty of the California Institute of Technology as a Senior Research Fellow in Physics, Mathematics and Astronomy.

CIERA Third Annual Public Lecture

"Dark Energy and the Accelerating Universe:

Einstein's Blunder Undone"

To view Prof. Kirshner's talk, click on the play button above.

Prof. Robert Kirshner (Harvard-Smithsonian CfA)

November 1st, 2011
4:00pm at
Tech Ryan Auditorium

Exploding stars halfway across the universe reveal an extraordinary fact: the expansion of the universe is speeding up. We attribute this to a dark energy that acts to make the universe spring apart. The resulting picture is a truly strange one: most of the universe is in the form of dark matter we cannot see and dark energy we do not yet understand. Only 4% of the mass-energy of the universe is in the form of atoms that can make stars, galaxies, planets, and people. This talk will show how we know the universe is accelerating and sketch how today's idea of dark energy resembles Einstein's cosmological constant, an idea he invented in 1916 and discarded in 1931.

Robert Kirshner is Clowes Professor of Science at Harvard University. A 1970 graduate of Harvard College, Kirshner received his Ph. D. from Caltech and recently received an honorary Doctor of Science degree from the University of Chicago. His work with the High-Z Supernova team helped uncover the fact that the expansion of the universe is speeding up. Kirshner shared in the 2007 Gruber Prize in Cosmology for that work. Kirshner won the 2011 Heineman Prize for "his sustained and enduring contributions to our understanding of supernovae and cosmology." A frequent public lecturer on astronomy, he teaches a large undergraduate course at Harvard called "The Energetic Universe" and is the author of popular-level book The Extravagant Universe: exploding stars, dark energy, and the accelerating cosmos.

For the article by Science in Society about this research, please see "Our Rapidly Expanding Universe", an interview with Prof. Kirshner by Beth Herbert here.

CIERA Second Annual Public Lecture

"The Warped Side of our Universe:

From the Big Bang to Black Holes and Gravitational Waves"

Prof. Kip S. Thorne (California Institute of Technology)

October 18th, 2010
at Fisk Hall

There is a Warped Side to our Universe: objects and phenomena that are made from warped space and warped time. Three examples are black holes, the big-bang in which our Universe was born, and ripples in the fabric of space-time called gravitational waves. Thorne will describe the Warped Side of our Universe and the quest to probe it theoretically using computer simulations, and observationally using gravitational waves.

Kip Thorne is Feynman Professor of Theoretical Physics, Emeritus, at Caltech. Dr. Thorne is one of the world's leading experts on the astrophysical implications of Einstein's general theory of relativity, known for his prolific contributions in gravitational physics and astrophysics. He is currently working on a film with Steven Spielberg.

CIERA Inaugural Public Lecture

"The Race for Habitable Worlds and Life in the Universe"

Prof. Geoffrey Marcy (University of California, Berkeley)

February 5th, 2010
at Tech Ryan Auditorium

Science Fiction has deluged us with images of our Milky Way Galaxy teeming with habitable planets and populated by advanced civilizations engaged in inter-stellar communication, commerce, and conflicts. Back in our real universe, Earth-like planets and extraterrestrial life have proved elusive. None has been found. This year, 2010, astronomers are launching the first searches for Earth-like worlds around other stars, using extraordinary telescopes on the ground and in space. A worldwide race for the first habitable worlds and extraterrestrial life has begun.

This lecture will be followed by a special viewing session with Dearborn Observatory's historic 18.5-inch telescope at 6:15pm.
