*Event Type*: [[PublicLectures][Lecture and Stargazing]]<br>
*Title*: Searching for the Violent Births and Deaths of Stars with Night-Vision Goggles<br>
*Lecturer*: Kishalay De<br>
*Position*: PhD Candidate<br>
*Institution*: Caltech<br>
*Abstract*: <br>
Since the beginning of civilization, humans have observed and recorded
visible changes in the sky.  Today, after decades of investigation, astronomers 
have created exquisite catalogs of stars that flare and dim to mark their 
births, deaths, and cataclysmic interactions. Yet, it is well known that a 
substantial fraction of stars in our own galaxy and beyond are obscured 
by interstellar dust absorbing and blocking their visible light.  In this talk, we will 
learn why so many stars in the universe are hidden from human eyes, 
and how infrared observations allow us to pierce through the intervening 
dust to see them clearly. I will talk about recent technological developments 
(similar to night vision goggles) that are finally allowing us to scan the skies 
at infrared wavelengths and reveal the dynamic and explosive hidden universe.
