Limerick Astronomy Club: Cosmic fireworks will put on show in our May skies
Limerick Astronomy Club meets in Mary Immaculate College
AS spring blooms across Limerick, the night sky offers its own spectacular display. May brings several noteworthy astronomical events worth observing.
The η-Aquariid meteor shower reaches its peak on May 5, producing up to 40 meteors per hour. What makes this shower particularly special is that about 25 percent of these meteors leave persistent trains that can last for several seconds or even minutes. With the Moon setting towards midnight, observing conditions in the early morning hours will be favorable. These meteors originate from the famous Halley's Comet, making them fragments of one of astronomy's most celebrated celestial visitors.
For planet watchers, May offers a rich viewing experience. Venus will reach its greatest western elongation on May 3, shining brilliantly at magnitude -4.4 in the pre-dawn sky. Jupiter continues its journey through Taurus, while Saturn graces the morning sky in Pisces. The minor planet Vesta reaches opposition in Libra on May 2, making it an excellent time for observation.
May also marks the birth month of pioneering astronomer Cecilia Payne-Gaposchkin, born in 1900. Her groundbreaking research revolutionized our understanding of the universe's composition. Against prevailing scientific opinion, Payne-Gaposchkin demonstrated that hydrogen and helium are the predominant elements in stars—findings that fundamentally altered our cosmic perspective. Her work showed that hydrogen comprises about 73 percent of the universe's mass, with helium accounting for another 25 percent—an astonishing discovery that laid important groundwork for later cosmological theories.
Looking to the future of astronomy, ground was first broken in May 2017 for the Extremely Large Telescope (ELT) currently under construction in Chile represents humanity's most ambitious ground-based observatory. With its massive 39-meter primary mirror, the ELT will help scientists search for Earth-like exoplanets, analyze the universe's earliest galaxies, and probe the mysteries of dark energy and dark matter when it begins operations.
The Limerick Astronomy Club meets monthly on the first Thursday of every month, in Mary Immaculate College, Room 202 at 8pm. We'd love to welcome you and embark on this cosmic journey together. Reach out to us at [email protected] for more info
