Celestial events have long been associated as harbingers of doom. In the past, comet sightings were associated with change or seen as a bad omen. Today, we know that comets are left over from the formation of our solar system. Short period comets that have orbits less than 200 years originate from the Kuiper Belt, just outside of Neptune. Long period comets, which may come around once every thousands to millions of years originate from the Oort Cloud, 100 A.U. from the Sun. Recent sample missions have found that materials in these comets are similar to material found in the inner solar system but have been preserved in these frozen objects from the outer fringes of our solar system. (Credit: BBC Sky at Night Magazine) NAA member and veteran observer, Ron Ziss, will review current comets that may be observed and highlight the “devil comet” 12P/ Pons-Brooks, which may also be visible during the eclipse on April 8, 2024. Comets are exciting objects to view, but it may take practice to learn to “star hop” to locate them. If you are looking to add comet observing to your routine, or are simply interested in comets, you may want to check out Ron’s April fundamentals presentation. Our April Fundamentals Program will be held on April 16th at 7:30 pm, at the Naperville Municipal Center, located in downtown Naperville, at Aurora Ave. & Eagle St. The location is downstairs, in Meeting Room B. The public is welcome to attend, free of charge.
Europa Clipper: NASA Investigates an Icy Ocean
Europa, one of Jupiter's four biggest moons, appears to harbor a liquid ocean not far beneath its bright, icy surface. Is there life there? NASA plans to fly the Europa Clipper spacecraft to orbit Jupiter and, making frequent flybys of Europa, will study the...
Astronomy Fundamentals: The Last Trillionth of the Journey
As stargazers, we look out across space at objects floating in what is mostly vast emptiness. The light we see travels at its breathtaking speed through a vacuum, only now and then perhaps encountering some wisps of gases and dusts. To an observer on our Moon, or to...
Artemis Program: Returning to the Moon After More Than 50 Years
The Artemis project is our follow-up to the Apollo missions. In Greek mythology Artemis is the twin sister of Apollo. The goal is to not be a repeat of Apollo, but to achieve a sustainable long-term presence at the Moon. Artemis 1 launched November 16, 2022 and...
Astronomy Fundamentals: Exploring the Winter Sky – Going Beyond the Usual Suspects
The Winter season brings some of the brightest stars in view. And with those stars, some bright deep sky objects. The season brings a chance to observe M42, M44, and M45, as well as the Winter Milky Way through Cassiopeia. However, the same old objects every year may...
