The Guild of Nature Artists is dedicated to creating and promoting wildlife and nature art in various styles and media. This group of amateur and professional creatives includes naturalists, illustrators and those specializing in fine arts.

Meetings begin in the lobby, then move into the galleries.

Curator of Invertebrate Paleontology Joe Hannibal and Curator of Mineralogy Dr. David Saja contributed their expertise to the rehabilitation of the 116-year-old Cuyahoga County Soldiers' and Sailors' Monument, located on Public Square in downtown Cleveland. Hannibal and Saja investigated the warping of the large marble tablets in the Monument that contain the names of County soldiers and sailors who served in the American Civil War.

Cosmic Collisions launches visitors on a thrilling trip through space and time—well beyond the calm face of the night sky—to explore cosmic collisions, hypersonic impacts that drive the dynamic and continuing evolution of the universe. Groundbreaking scientific simulations and visualizations based on cutting-edge research developed by Museum astrophysicists, scientists at the National Aeronautics and Space Administration (NASA), and other international colleagues—many seen for the first time—depict the dramatic and explosive encounters that shaped our solar system, changed the course of life on Earth, and continue to transform our galaxy. The new show explores the full range of space collisions, past, present, and future.

What we can see through our telescopes is an insignificant portion of our Universe. Most of the energy and matter is quite literally invisible. How do we know it's there, and what does it hold for the future Universe?

January and February are the final great viewing opportunities for Jupiter this year. How many cloud bands can we count?

This class is for entry level fly-tiers and those who want to polish their basic techniques in handcrafting artistic and functional traditional fishing flies. All materials and supplies are included. An interest in fishing is not necessary.

In 1901, Greek sponge divers recovered from a shipwreck of circa 65 BCE a remarkable bronze device (dating ca. 200 - 65 BCE) with gears now known to the world as the Antikythera Mechanism. Recently, a group of researchers has examined this badly corroded and brittle device with modern technologies that have revealed that the back of the device housed a Saros eclipse-prediction dial, as well as a Greek lunisolar calendar that was regulated according to the 235 months of the Metonic cycle and probably also the 76 years of the Callippic cycle. Furthermore, another dial was revealed to indicate the years in which some of the more important Panhellenic athletic games fell, including the famous Olympic games. The authors who published these results (Freeth, Jones, et al., Nature 2008), argued that the lunisolar calendar belonged to Corinth or one of its colonies, especially Syracuse, and that this lunisolar calendar commenced one month after the autumnal equinox, or roughly in October. This talk will demonstrate that the calendar is indeed that of Corinth, or one of its colonies in NW Greece, or a city of Epirus that adopted the Corinthian calendar, but that it cannot be that of Syracuse. It will also argue that calendar starting season should be backed up one or two months, that the device is more likely to come from the Rhodian school of astronomy rather than the Syracusan, and it will reveal the heretofore unidentified game in year 4 on the Games Dial, and offer a new explanation of its four divisions. All these new findings will have a significant impact on calibrating the starting time of the mechanism, and thus the date of the world's oldest known analogue computer.

This illustrated program will provide an overview of the Ice Age animals of Ohio with a special focus on finds in the Cleveland region. The program willinclude a tabletop display of samplings of local mastodon bones from the Museum's collection.
