The Astronomical Society of Greenbelt will present material and lead a discussion on the topic of dark matter and related matters, including dark energy, cosmological structure, relativistic and quantum mechanical considerations, and the present state of physics regarding all this. Dark matter has been hypothesized by astrophysicists to account for galactic motions which cannot be… Read More »August Meeting: Dark Matters
We'll be observing Summer Triangle objects and more, possibly including the Moon, Jupiter, and Saturn if they are not obscured by houses or trees. Chad Leader and Conrad Terrill will be doing the observing from their back yards, and George Stallings might be able to join as well. All are welcome to join the Zoom… Read More »Virtual Star Party
Dr. Tim Hamilton, professor of physics and director of the Clark Planetarium at Shawnee State University, will present a lecture entitled "Using Gravitational Lenses as Natural Telescopes." This event is free and open to the public. Join the Zoom meeting.
The radiant point for the Draconids is the head of the dragon in the constellation Draco. The peak is on the evening of October 8. Unlike most meteor showers, this one is best viewed in the early evening. This year, a waxing crescent moon will set during dusk, so it won't obscure the shower. The… Read More »Draconid Meteor Shower
Astronomy Day is a biannual event held in the United States and other countries. It is intended to promote interest in astronomy and interaction between the general public and various astronomy enthusiasts, groups, and professionals. The day is observed in the spring and the fall. Astronomy Day in the spring always falls on a Saturday… Read More »Astronomy Day
Unfortunately, the full moon coincides with the peak of the Orionids this year, which occurs in the early morning of October 21. The radiant point of the Orionids is the club of the hunter Orion. The Orionids usually produce 10–20 meteors per hour.
Dr. Maria Hamilton, professor of physics at Marshall University, will present a lecture entitled "The Curious Incident of the Neutron Star Crashing at Night." Dr. Hamilton is the recipient of a prestigious fellowship from the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara. Her research centers on investigating the gravitational waves… Read More »October Meeting: The Curious Incident of the Neutron Star Crashing at Night
The two Taurid Meteor Showers last for several weeks before and after their peak dates, but often produce only around 5 meteors per hour, even at their peak. What makes them worth the effort, however, is the fact the they often include a large number of fireballs, extremely bright, long-lasting (1–3 seconds) meteors. The South… Read More »Taurid Meteor Showers
