4. 4 Astronomical Instruments

5. Sundials Sundials were used to determine the time of day for thousands of years. By the 17th century, portable dials became popular with people like soldiers and merchants. Some could be adjusted to tell the correct time at a variety of different latitudes in different parts of the world.

6. Dials 6 Timekeeping with heavenly bodies wasn't limited to the Sun. This Italian rosewood dial from the 17th century was made to line up with the Big Dipper's pointer stars, enabling users to tell the time even in the middle of the night—provided they had a clear sky .

7. Astrolabe 7 Astrolabes were initially created in the 11th century BC and improved throughout the ages to be able to find and anticipate the movement of celestial bodies like the Moon, planets, and stars. Examples like this 18th-century bronze astrolabe, which was made in Persia, were used for a variety of purposes, including surveying, telling time, and predicting and documenting the motions of stars and planets .

8. 1 Star Maps Utilizing telescopes allowed astronomers to obtain a closer look than ever before at the sky and the objects that populate it starting in the 17th century. More accurate star mapping was spurred by new and improved instruments . Burritt's Atlas, a well-known collection of celestial charts created in the 1800s by Connecticut educator Elijah Burritt to "illustrate Burritt's geography of the Heavens," is among the items the Museum has on hand.

9. 9 A recent notion that Stonehenge was constructed by ancient astronomers in the 1960s stated that its enormous pillars were used to forecast solar and lunar eclipses as well as to mark the summer and winter solstices . The quadrant is a very simple instrument that enables the user to find their latitude by calculating the height of a celestial body. The angle of elevation between the horizon and celestial objects like the sun, planets, moon, or stars is referred to as height when employed in celestial navigation or astronomy.
