Each month, I host the Public Lecture Series at the Space Telescope Science Institute in Baltimore, Maryland. Before introducing the main speaker, I present some Hubble discoveries and other astronomical findings and events called "News from the Universe".
The stories I covered for the November 1, 2016 lecture are:
-- Astronomers estimate two trillion galaxies in the universe
-- Hubble observes the "ghost" of a star
The slides are truncated during the first part of the presentation due to a webcasting format error (operator selected 4x3 aspect ratio instead of 16x9). Our apologies.
Here are the description and links to the main speaker's presentation for the November 2016 Public Lecture Series:
The Cosmology Large Angular Scale Surveyor
Tobias Marriage, Johns Hopkins University
The Cosmology Large Angular Scale Surveyor (CLASS) project is an ambitious effort to study the Cosmic Microwave Background (CMB). Its aims to make a unique measurement of CMB polarization that will characterize the conditions during the early universe and help pinpoint when the first stars formed. To accomplish these goals, CLASS researchers have invented and implemented new technologies for telescopes that operate high in the Andes in the Atacama Desert of northern Chile. This international team is led by Johns Hopkins University with key contributions from young researchers. Dr. Marriage will discuss the science and technology behind CLASS, and provide an update on its progress.
