Join your neighbors at the
Join your neighbors at the lower parking lot at Marsh Creek State Park in Eagle, Chester County for an exciting evening exploring the wonders of the heavens.
Watch a sunset become a star-laced sky, view planets, star clusters and galaxies using our members’ telescopes and live view star cameras. There will be activities to thrill and challenge all ages, so don’t miss out!
These events are free of charge provided to the community by your neighbors who are members of the Chesmont Astronomical Society. Free will donations to the society will be gratefully accepted.
Because these events are clear, dark sky, weather dependent be sure to check our website (www.chesmontastro.org) after 5:00 pm for last minute schedule changes.

Dr. Veronique Petit will be our Guest Speaker.
Massive stars, which can have up to one hundred times the mass of our own Sun, are the powerhouses of our Galaxy. They shape their surroundings though their intense radiation and winds, trigger the formation of new generations of stars, and produce almost all of the heavy chemical elements in the Universe through nuclear reactions in their cores. Understanding the life-cycle of these stars is thus of great importance to astrophysics, even more so since the recent detection of gravitational waves, which originate from the coalescence and merger of black holes and neutron stars formed when massive stars die. These waves, now detected by the 2017 Nobel prize-winning LIGO experiment, are revolutionizing the field of stellar astrophysics by providing much-needed observational constraints on the endpoint of massive star evolution. Dr. Petit will discuss the most important factors dictating the evolution of massive stars, including an important factor has only been recently recognized and is a subject of intense research at UD: the presence of a surface magnetic field. These surface magnetic fields have the potential to dramatically alter the life-cycle, and ultimate fate, of a massive star.
