2017 Fall Science Colloquia
Raffaella Margutti (Northwestern University)
Observations are drawing a complex picture of the latest stages of massive stars evolution and their explosions. In this seminar I concentrate on two among the least understood aspects of stellar evolution, adopting an observational perspective: How ...

2017 Fall Science Colloquia
Mark Devlin (University of Pennsylvania)
Researchers have been utilizing the measurements of the Cosmic Microwave Background (CMB) for the last several decades to study the birth and evolution of our Universe. I will review the science behind the CMB and describe how we extract cosmologica ...

2017 Fall Science Colloquia
Geronimo Luis Villanueva (Goddard Space Flight Center)
We recently established that Mars lost an ocean’s worth of water, while the Curiosity rover has recently detected organics on the Martian surface and in the atmosphere. If Mars had a rich chemical and diverse past, how much of these biomarkers were l ...

STScI Public Lecture Series
Nolan Walborn (Space Telescope Science Institute)
Luminous blue variable stars showcase a spectacular and rare unstable stage in the death of massive stars. These supergiant stars can rapidly and unpredictably change both their brightness and spectra in outbursts that can last for decades. Some ...

2017 Hot Sci @ STScI
Bradley Peterson (Space Telescope Science Institute)
The Large Ultraviolet, Optical, and Infrared Surveyor (LUVOIR) is one of the future mission concepts identified in the NASA Astrophysics Roadmap of 2014. NASA is currently funding studies of four such missions with the intent of identifying the scien ...
2017 Hot Sci @ STScI
Kirill Tchernyshyov  (JHU)
There is general agreement that the ISM of the Milky Way is arranged into a spiral-like pattern of some sort, though there is not yet agreement on how regular this spiral-like pattern is or how it evolves. To investigate this and other questions rela ...

2017 Hot Sci @ STScI
Dominika Wylezalek (JHU)
Feedback from accreting supermassive black holes is now a standard ingredient in galaxy formation models. But while many compelling models of AGN feedback exist, there is no clear data-driven picture of how AGN-driven winds are launched, how they pro ...
2017 Hot Sci @ STScI
Ben Sargent  (Space Telescope Science Institute)
The asymptotic giant branch (AGB) phase is one of the last phases of a star’s life. AGB stars lose mass in an outflow in which dust condenses and is pushed away from the star. Extreme AGB stars are so named because their very red colors suggest ver ...
