In June, observe
the Hercules Globular Cluster!
A globular cluster is a collection of tens to hundreds of thousands of stars held together by gravity. Discovered in 1714, the Hercules Globular Cluster is one of the brightest, closest, and most beautiful globular clusters that can be observed from the northern hemisphere.
Video tour:
- Tonight’s Sky for June, 2009
- “Tonight’s Sky” is a monthly video guide to the night sky. This presentation highlights M5, a globular cluster very similar to the Hercules Globular Cluster.
Graphic Organizers:
- Comparison of Globular and
Open Star Clusters
- “Graphic Organizers” are T-charts and Venn diagrams that compare and contrast various celestial objects and phenomena. The downloadable organizers are available in teacher versions (full chart) and student versions (blank organizer with images). This Venn diagram shows the similarities and differences between the two types of star clusters: globular and open.
Myths vs. realities:
- Stars
- “Myths vs. realities” is a collection of common misconceptions about celestial objects and phenomena. The misconception is stated in the “myth” while the “reality” explains the true situation. “Myths vs. realities: Stars” addresses common misconceptions about stars and stellar evolution.
Lithographs:
- Globular Cluster M80
- Lithographs are Hubble Space Telescope images of celestial objects that include informational text and inquiry-based classroom activities. This lithograph features the globular cluster M80, a cluster of stars very similar to the Hercules Globular Cluster.
