SUMMARY:Online Beginner's Class
DESCRIPTION:This event is free and open to public; to attend please register using the zoom.us link on the box above. \nThis session of the Beginners Astronomy Class covers the science behind the telescope. \nHow do our eyes actually perceive objects we see in the telescope and what is the physics that allows that perception. \nFor details\, please visit here and download the sample information PDF package. \nViews: 167

SUMMARY:Quadrantids Meteor Shower
DESCRIPTION:The Quadrantids is an above average shower\, with up to 40 meteors per hour at its peak. It is thought to be produced by dust grains left behind by an extinct comet known as 2003 EH1\, which was discovered in 2003 \nViews: 167

SUMMARY:Online General Meeting - January 2021
DESCRIPTION:This is an online event\, to attend please register with zoom using the link on the box above. \nDark Matter and the Dance of Dwarf Galaxies\n \nMajor galaxies\, such as our cosmic home the Milky Way\, the nearby Andromeda galaxy\, or Centaurus A\, are surrounded by swarms of smaller dwarf satellite galaxies. Over the past 15 years\, our knowledge of these satellite galaxies has exploded. The number of known Milky Way satellites has quadrupled\, and highly precise measurements of their motions have provided unprecedented insights into their complex orbital dance. In my research\, I investigate the distribution and motion of satellite galaxies to test our ideas of how the cosmos in general\, and galaxies in particular\, have formed and evolved. Our current leading model of cosmology was largely developed on cosmic scales\, and implies that most of the mass in the Universe is dominated by unknown stuff: Dark Matter. Based on this cosmological model\, computer simulations can nowadays follow the emergence and evolution of structure in model universes. These simulations predict the distribution and properties of galaxies down to the smallest scales (astronomically speaking). They predict a highly chaotic tangle of satellite galaxies. In contrast\, my research finds that the observed situation resembles an ordered choreography: the satellite galaxies around the Milky Way\, Andromeda\, and Centaurus A are aligned along planes. Many satellites also move along these structures in a common direction. This finding poses a serious challenge to our model of cosmology – and might point at a fundamental misinterpretation of cosmic proportions. \nMarcel S. Pawlowski\n \nMy research is situated at the intersection of observations and cosmological simulations. I am most interested in testing our cosmological knowledge and our understanding of the properties and dynamics of dwarf galaxies with observations of nearby systems of satellite galaxies. After receiving my PhD from the University of Bonn in 2013\, I moved to the United States for a postdoc position at Case Western Reserve University in Cleveland\, Ohio. In 2016\, I was awarded a NASA Hubble Fellowship to work at the University of California Irvine. At the end of 2018 I moved back to Germany to my current position as Schwarzschild Fellow at the Leibniz-Institute for Astrophysics in Potsdam. \nViews: 167

SUMMARY:Full Moon
DESCRIPTION:The first full moon of the year is colloquially known as Wolf Moon in many northern cultures. A Full Moon occurs when the Sun and the Moon are on opposite sides of the Earth. \nViews: 167
