Space enthusiasts in certain regions of the world will get free seats to a potentially once-in-a-lifetime event on the celestial stage later this month.
On July 27, lucky stargazers will see the longest total lunar eclipse of the 21st century ― also known as a blood moon (Chandra grahan).
The nearly two-hour total eclipse will be visible to people in parts of Africa, the Middle East and Asia, according to NASA.
