Hubble's Universe Unfiltered

    News from the Universe, February 2017

    by Frank Summers

    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 February 7, 2017 lecture are:

    -- A shadow across the disk of TW Hydrae may indicate the presence of an unseen planet

    -- Nebula NGC 248 as observed by the SMIDGE project

     

     

    Here are the description and links to the main speaker's presentation for the February 2017 Public Lecture Series:

    Mapping the Heavens: The Radical Scientific Ideas That Reveal The Cosmos

    Priyamvada Natarajan, Yale University

    The cosmos, once understood as a stagnant place, composed of the ordinary, is now an expanding universe filled with dark mysteries. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes - these are some of the puzzling cosmological topics of the early twenty-first century. Dr. Natarajan will delve into the ideas that reshaped our universe over the past century and provide a tour of the “greatest hits” of cosmological discoveries. The acceptance of such new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. However, as shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe.
