Stephen Hawking (1942-2018):  English theoretical physicist and cosmologist.  His studies concluded that there is likely no border or boundary to the universe.

Annie Jump Cannon (1863-1941):  American astronomer.  She has been called the “census taker of the sky.”  She manually classified around 350,000 stars.

Classifying the stars has helped materially in all studies of the structure of the universe.

Johannes Kepler (1571-1630):  German astronomer.  His research determined that as the planets travel around the Sun, they move in an elliptical orbit.

The treasures hidden in the heavens are so rich that the human mind shall never be lacking in fresh nourishment.
