Imaging the Deep Sky with Rolf Wahl Olsen - Monthly Meeting April
My talk will be about latest images and achievements in the last two years, including the first amateur image of light echoes of Supernova 1987A and a new collaboration with NASA on a multi-wavelength image of Centaurus A.
I have been interested in astronomy for as long as I can remember and have observed the night sky visually for decades with both binoculars and telescopes. In 1990 I got my first telescope, a 60mm alt-az refractor. A couple of years later I upgraded to a 100mm refractor on an equatorial mount and in 1995 I got a 10 inch f/5 Newtonian reflector. This telescope was used extensively for both planetary and deep sky observing and in 2003 I ventured into the world of astrophotography and began taking images with a long-exposure modified webcam. In 2011 I built a Serrurier truss 12.5 inch f/4 Newtonian and then upgraded the webcam to a highly sensitive QSI683wsg CCD camera which I now use to take all my images.
The modified webcam was a great opportunity to learn as it required me to really work on developing processing skills in order to achieve good results. It also forced me to think carefully about my choice of subjects, given the webcam’s limited resolution and low sensitivity. My later images taken with the CCD camera greatly benefited from these early lessons.
I enjoy photographing all astronomical subjects but perhaps my favourites are galaxies, especially peculiarly shaped ones or distant galaxy clusters, or those engaged in dramatic mergers such as the famous pair of Antennae galaxies. I enjoy taking images that are unusual, either being of a rarely imaged object, or perhaps a familiar object presented in a new way. Among my images you will find exotic objects like the circumstellar disc of Beta Pictoris, gravitational lenses, quasars, distant galaxy clusters and extragalactic globulars. I find that these obscure targets often have a very interesting story to tell.
Interview: Oumuamua, Aliens and Astrophysics with Dr. Avi Loeb
Professor Avi Loeb is a theoretical physicist from Harvard who has worked on many advances in space and astrophysics. He helped predict exoplanet discoveries using microlensing, worked on the mathematics for the Event Horizon Telescope, and has many fascinating opinions about the search for extraterrestrials. https://lweb.cfa.harvard.edu/~loeb/ 🚀 OUR WEBSITE:

Weekly Space Hangout: April 7, 2021 — "The Disordered Cosmos" with Dr. Chanda Prescod-Weinstein
This week we are very excited to welcome Dr. Chanda Prescod-Weinstein to the Weekly Space Hangout. Chanda is an assistant professor of physics and astronomy and core faculty in women’s and gender studies at the University of New Hampshire. She is also a columnist for New Scientist and Physics World. In her first book, THE DISORDERED COSMOS: A Journey into Dark Matter, Spacetime, and Dreams Deferred (Bold Type Books), Chandra brings readers into the world of particle physics and the cosmos — all while making an urgent call for a more just and inclusive practice of science that expands our understanding of the universe and our place in it. Chanda's research in theoretical physics focuses on cosmology, neutron stars, and dark matter, and she is active in Black feminist science, technology, and society studies. Essence magazine recognized her as one of “15 Black Women Who Are Paving the Way in STEM and Breaking Barriers.” She has been profiled in several venues, including TechCrunch, Ms. Magazine, Huffington Post, Gizmodo, Nylon, and the African American Intellectual History Society’s Black Perspectives. A cofounder of the Particles for Justice movement, Chanda has received the 2017 LGBT+ Physicists Acknowledgement of Excellence Award for her contributions to improving conditions for marginalized people in physics, as well as the 2021 American Physical Society Edward A. Bouchet Award for her contributions to particle cosmology. Be sure to visit Chanda's website: http://www.cprescodweinstein.com/ and follow her on Twitter (https://twitter.com/ibjiyongi), LinkedIn (https://www.linkedin.com/in/chandaprescodweinstein), and Facebook (https://www.facebook.com/chandapw/).

SpaceX is targeting Wednesday, April 7 for launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous window is at 12:34 p.m. EDT, or 16:34 UTC, and a backup opportunity is available on Thursday, April 8 at 12:12 p.m. EDT, or 16:12 UTC. The Falcon 9 first stage rocket booster supporting this mission previously supported launch of NASA astronauts Bob Behnken and Doug Hurley to the International Space Station, ANASIS-II, CRS-21, Transporter-1, and two Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing prevouisly supported launch of AMOS-17 and two Starlink missions, and the other previously supported a Starlink mission.

YouTube Channel: https://support.google.com/youtube/answer/1646861 Main Talk: “X-ray Mysteries ” Supernova Remnant Kinematics and Cluster Metallicity by Anne Blackwell X-rays illuminate some of the highest energy structures in the Universe. Astronomers use them to study a broad range of size of objects from single stars to the largest structures in the Universe – galaxy clusters. Each object illuminates a different mystery of the Universe. This talk will cover two in particular: the kinematics of supernova remnants (SNRs), and the missing metals in high-mass galaxy clusters. Anne Blackwell is a second-year graduate student in Astronomy & Astrophysics at the University of Michigan. She works with Dr. Joel Bregman using X-rays to study galaxy groups and clusters. Her primary goal is to understand where metals in high-mass clusters came from. In addition to research Anne is part of the Astronomy on Tap organization committee for Ann Arbor and the Dark Sky outreach program - a group committed to preserving Michigan Dark skies and education of light pollution problems and solutions. In 2015 she graduated from the College of William & Mary with a degree in Physics. Short Talk: Of Schmidt Cameras, Comets, and Asteroid Bennu by David Levy David H. Levy is a Canadian astronomer and science writer who co-discovered Comet Shoemaker–Levy 9 in 1993, which collided with the planet Jupiter in 1994. He has written 34 books, mostly on astronomical subjects, and provided periodic articles for Sky and Telescope magazine, as well as Parade Magazine, Sky News and, most recently, Astronomy Magazine. He will be speaking of his friendship with longterm W.A.S. members and professional astronomers Rik and Dolores Hill. ---

What is Dark Matter? The Evidence, the Candidates & the Search - Introduction to Astronomy April 21
85% of the matter in the Universe is elusive dark matter that we cannot directly observe, but presence is seen through its effects on the surrounding environment. Tonight, Chris Benton discusses compelling evidence for dark matter and its importance in the structure and evolution of the Universe. Following this, an outline of dark matter’s apparent properties leads into identifying the candidate particles and the experiments designed to detect them.
