Explore the Celestial Delights: Witness the Majestic Great Square of Pegasus Galloping Through the Night Sky

Observing the Great Square of Pegasus: A Celestial Delight

Introduction

The Great Square of Pegasus, one of the most famous groupings of stars in the night sky, is set to rise higher throughout the month of September. This asterism, which forms a recognizable pattern in the sky, is not an official constellation but holds significant cultural and astronomical importance. In addition to its beauty, the Great Square offers sky-watchers the opportunity to explore the nearby star 51 Pegasi, which is home to the first exoplanet discovered orbiting a sun-like star. As the Great Square and the Pegasus constellation reach their best viewing position in October, it is the perfect time to familiarize oneself with this celestial wonder.

Getting Acquainted with the Great Square

The Great Square of Pegasus is composed of four stars of equal brightness: Scheat, Alpheratz, Markab, and Algenib. These stars form the “body” of the fabled winged horse from Greek mythology. To locate the Great Square, observers should look towards the eastern sky in the evenings throughout September. On September 7, it should be visible at sunset, approximately 16 degrees above the horizon. By the end of the month, the square, along with the rest of the Pegasus constellation, will be twice as high by sundown.

Astronomical Significance

While the Great Square is a sight to behold, its significance goes beyond its aesthetic appeal. For the Anishinaabe people of the Great Lakes region, the Great Square represents the torso of Mooz, the Moose, adding cultural richness and storytelling to the celestial marvel. Furthermore, the Great Square offers an opportunity to spot 51 Pegasi, a yellowish star also known as Helvetios, which is home to the first exoplanet ever discovered orbiting a sun-like star. This exoplanet, named 51 Pegasi b, is a Jupiter-sized planet located 20 times closer to its star than Earth is to the sun.

Equipment Recommendations

To fully appreciate the beauty of the Great Square and the Pegasus constellation, it is recommended to use suitable equipment. The Celestron Astro Fi 102 telescope is a top pick for exploring the moon, stars, and constellations up close, making it an excellent choice for beginners. Additionally, for those interested in taking their stargazing experience outdoors, the use of binoculars with wide-angle optics is highly recommended. These portable devices provide a wider field of view and make it easier to observe the stars.

Astrophotography

For those eager to capture stunning images of the Great Square and the night sky in general, there are several resources available. Guides on how to shoot the night sky, as well as recommendations for the best cameras and lenses for astrophotography, can assist in achieving breathtaking results. Sharing these images with the Space.com community through email or participating in the Space Forums allows for engagement and further discussion of the wonders of the universe.
