Why physicists are hunting the strangest of the ghost particles

    From Live Science, Jan. 12, 2019: In the 1920s, careful and detailed observations of those decays found tiny, niggling discrepancies. The total energy at the start of certain decay processes was a tiny bit greater than the energy coming out. The math didn’t add up. Odd. So, a few physicists concocted a brand-new particle out of whole cloth: A little, neutral one. A neutrino.

    After mapping millions of galaxies, Dark Energy Survey finishes data collection

      From University of Chicago, Jan. 9, 2019: After scanning about a quarter of the southern skies over 800 nights, the Dark Energy Survey finished taking data on Jan. 9. It ends as one of the most sensitive and comprehensive surveys of its kind, recording data from more than 300 million distant galaxies. Fermilab, an affiliate of the University of Chicago, served as lead laboratory on the survey, which included more than 400 scientists and 26 institutions.

      Supercomputing Dark Energy Survey data through 2021

        From insideHPC, Jan. 9, 2019: After scanning in depth about a quarter of the southern skies for six years and cataloging hundreds of millions of distant galaxies, the Dark Energy Survey finishes taking data on Jan. 9. The National Center for Supercomputing Applications at the University of Illinois will continue refining and serving this data for use by scientists into 2021.

        Missing galaxies? Now there’s too many

          From Quanta, Jan. 9, 2019: Fermilab scientist Alex Drlica-Wagner comments on dark matter in this article on a paradoxical problem in astronomy: New surveys have allowed astronomers to find more satellite galaxies that had previously been hidden. At the same time, updated computer simulations predicted the existence of far fewer galaxies than their predecessors did.

          The snowman orbiting the sun

            From CNN, Jan. 3, 2019: Fermilab scientist Don Lincoln discusses NASA’s New Horizons spacecraft and Ultima Thule, a frigid, snowman-shaped block of ice located about 4 billion miles from the sun.
