Enrollment: Unlimited: No advance sign-up
Prereq: none
In the summer of 1999, NASA launched the third of its great observatories -- the Chandra X-ray telescope. Like the Hubble Space telescope which preceded it, Chandra is designed to have an unprecedented ability to create images and spectra of astrophysical objects, except working with high energy X-rays instead of optical light. This means that Chandra views some of the universe's most exotic and energetic phenomena: supernovae, neutron stars, black holes, jets traveling at nearly the speed of light emanating from near the center of clusters of galaxies. In this talk, we'll take a tour of the discoveries made by the Chandra X-ray telescope, starting with studies of our own solar system, moving outward to nearby stars, to the center of our own Galaxy where a black hole 40 millions times the mass of our Sun lurks, to distant clusters of Galaxies where the most massive black holes, billions of times the mass of our Sun, reside.
No enrollment limit, no advance sign up.
PLEASE NOTE: Following this talk there will be a tour of the Chandra Space Telescope ACIS CCD Lab by

What does a typical planetary system look like? Thanks to an enormous amount of observational work, we know now that planet formation can be considered efficient: most stars like the Sun host an exoplanet. Furthermore, systems of multiple planets are also par for the course. However, the systems we are finding don't always resemble our own Solar System. I'll discuss how we measure the shapes and orientations of planetary orbits when we cannot directly see the planets themselves, and then describe a few of the most intriguing multi-planet systems we've found.

Instruments That Enable the Exploration of the Universe
Hunting Dark Matter
Understanding the composition and properties of the matter in the universe is one of the most basic goals of physics, yet we know scandalously little about most of the matter. A concordance of diverse evidence from astrophysics and cosmology suggests that 85% of the matter in the universe is "dark": it is non-electromagnetically interacting and fundamentally different than the familiar matter of atoms that we experience in our day-to-day life. Though the existence and astrophysical properties of dark matter are established, its particle properties are unknown. I will describe the different pieces of evidence that have led to our current understanding of dark matter, culminating in the state-of-the-art direct searches that are probing its particle properties.
No enrollment limit, no advance sign up for this talk. Please note, however, that there is a tour of the Operations Control Center for the Chandra Space Telescope from 3:15-4:15.

Enrollment: Unlimited: No advance sign-up
Prereq: none
We know quite a lot about the very early universe from observations of the Cosmic Microwave Background and about the later universe from observations of distant galaxies and supernovae. But the period between--and therefore a huge volume of the observable universe--remains unexplored. We know that during that time the universe went from dark to bright as the first stars and black holes formed and helped ionize the hydrogen between galaxies. By studying the state and distribution of that hydrogen with novel radio telescopes, we hope to soon shed light on the so-called "Cosmic Dawn" in order to test our astrophysical and cosmological theories that describe history of the universe from the Big Bang to today.

Life on Mars
Sarah Johnson, Visiting Scholar
Enrollment: Unlimited: No advance sign-up
Attendance: Participants welcome at individual sessions
This seminar will explore the history and cultural resonance of the search for life on Mars. We'll trace how scientific ideas about Mars have evolved as we have learned more about the planet, from our 19th centrury speculations about an advanced civilization on the planet's suface to our current belief that, at most, there may be microbes within the planet's interior. We will explore why, despite our diminished expectations, the search for life on Mars continues today with as much, or more, energy and resources as any point in the past. We'll read firsthand accounts of scientists through the generations, examining not only what it means for a world as rich, complex, and enigmatic as our own to join the sphere of human significance, but also how, in different ages, our conceptions of Mars have reflected a telling portrait of life on Earth. In so doing, the seminar will illustrate one of the core lessons of the space age: that the act of exploring another world invariably reveals so much about our own.

Enrollment: Limited: Advance sign-up required
Sign-up by 01/10
Limited to 35 participants
Attendance: Participants must attend all sessions
The UN Space Treaty of 1967 states "that all parties to the Treaty shall pursue studies of outer space, including the Moon and other celestial bodies, and conduct exploration of them, so as to avoid harmful contamination and also adverse changes in the environment of the Earth resulting from the introduction of extraterrestrial matter, and where necessary, shall adopt appropriate measures for this purpose". The need to ensure that scientific integrity of samples and data obtained during investigations of other planets is not compromised has led NASA to develop five categories of target body/mission categories with a range of contamination controls. Over the two days this course will give an introduction to these NASA categories and various methods used for detection and control of microbial contaminants with some short hands-on experiments following the morning presentations and discussion to illustrate the difficulties surrounding achieving the appropriate level of spacecraft sterilization.

Einstein's theory of general relativity predicts the existence of gravitational radiation. Since gravity is a weak force, it takes extreme masses and energies to produce a detectable gravitational wave signature. Indirect evidence for the existence of this radiation has been collected using pulsar measurements. The Laser Interferometer Gravitational-Wave Observatory (LIGO) is an experiment designed to directly detect this radiation, and use it to study exotic astrophysical phenomena. To do this, LIGO must measure length changes with a precision of 10-19 meters, less than a thousandth of a proton diameter. In this talk, I will briefly discuss gravitational radiation and its sources, and I will also describe the LIGO detectors and the physics involved in their operation. Finally, I will discuss some of the quantum limits on making this type of precision measurement, and the ways in which LIGO hopes to beat these limits.
No enrollment limit, no advance sign up for this talk.
Please Note: A tour of the Laser Interferometer Gravitational Wave Observatory (LIGO) Lab will follow this talk. To take the tour (2:45-4:00pm), you must attend this talk and register for the tour.

One of the largest and most important questions regarding galaxy evolution is the role of the local environment, primarily other nearby galaxies and diffuse gas. Observations of galaxies using the full ensemble of modern telescopes have demonstrated that galaxies are inextricably linked to their neighborhoods through a number of processes that span from star formation and black hole accretion to dark matter and dark energy. In this talk, I will discuss the myriad ways in which we observe galaxies coupling to their environments with a particular emphasis on galaxies in the densest real estate in the Universe: galaxy clusters.
No enrollment limit, no advance sign up for this talk. Please note, however, that there is a tour of the Operations Control Center for the Chandra Space Telescope from 3:15-4:15.

In the 1920s, astronomers discovered that some of the spiral-shaped smudges seen in their telescopes were too distant to be part of our own Milky Way. These "island universes," now known as galaxies, have proved to be a critical component connecting cosmology to astrophysics. In this talk, we will follow the formation history of galaxies similar to our own Milky Way. Aided by computer visualizations, we will see how these galaxies grow from tiny density perturbations into the majestic gas disks we see today.

The Universe is Beautiful: The Art of Astrophysics
Astrophysicists try to share the mysteries of the Universe around us in a clear & understandable fashion, but we don't always succeed. It's a hard challenge - the wonders of the Solar System, the Galaxy, and the ever expanding Cosmos demand more of our imaginations than can be captured by numbers in a table or terms in an equation. However, a work of art can uniquely inspire us to look closely, to dream freely, to understand openly - anything from the smallest curiosity to the biggest discovery.
We're asking members of the MIT community to create works of art that help us visualize our Universe and how we observe it. Whether you're a photographer or a poet, a crafter or a coder, a musician or a moviemaker, we want you to use your talents and creativity to illuminate the beauty of astrophysical results. Please consider participating in this year's Art of Astrophysics competition during MIT's 2014 Independent Activities Period.
Entries must be received by January 29, 2014 at 5pm EST. Full details: The Universe is Beautiful: The Art of Astrophysics
The competition will culminate in an exhibition on Friday, January 31 in Lobby 10 from 4:00-5:30pm.

Most of the universe does not emit light. Dark matter outweighs baryonic matter in the universe approx. 5:1. So how do we learn about this dark universe when our primary tools for observing it require light?
Come learn about gravitational lensing, one of the tricks of astronomy that allows us to peer into the darkness of our universe. I will review the basics of gravitational lensing, and some of the neat things we can learn from it. I will then focus on weak lensing in clusters, the science behind some of the most beautiful Hubble images ever taken.
No enrollment limit, no advance sign up for the talk. Please note that there is a tour of the Space Nanotechnology Lab from 3:15-4:15pm. The tour is limited to 6 people.
