Sugar Creek Astronomical Society will discuss the world’s great telescopes at Hobbs State Park


The Sugar Creek Astronomical Society will present “The Great Telescopes of the World” and “Orientation to the Late Spring Sky” on Saturday at the Hobbs State Park Conservation Area.

There is now a new generation of ground-based telescopes, and more should be operational in a few years, according to the company. Such telescopes can be found in remote areas of Chile, South Africa, Hawaii, Spain, Puerto Rico, and other suitable places. They house some of the largest mirrors to date for collecting light from distant cosmic objects.

Some of these telescopes are:

• The WM Keck Observatory’s 33-foot Twin Telescopes, the second largest optical telescopes on Earth, located near the summit of Mauna Kea in Hawaii.

• The huge reflector helps make the Arecibo Observatory in Puerto Rico an incredibly sensitive radio telescope. These radio sources include distant quasars (a region at the center of a galaxy that produces a very large amount of radiation) and galaxies that emit radio waves that do not reach Earth until 100 million years later.

• The Square Kilometer Array (SKA) is an intergovernmental radio telescope planned for construction in Australia and South Africa that will be 50 times more sensitive than any radio telescope ever built. Such power could examine signals from the younger universe of 12 billion years ago.

The society will discuss these structures and then direct those present to the late spring sky. Observation of the night sky will include observation of the moon through high quality telescopes provided and operated by members of the Astronomical Society. Other sightings in the May 14 sky will include stars, constellations and star clusters.

People are encouraged to bring a flashlight (covered in red cloth or a red balloon), binoculars and/or a telescope, a folding chair (one per person), and a sky chart.

The recommended minimum age for this program is 8 years old.
