Hernando Cortés, the Spanish conquistador, used celestial navigation techniques that involved the sun, stars, and the moon to guide his expeditions. Specifically, he likely utilized the North Star (Polaris) for latitude and the sun's position for determining direction during the day. These celestial objects were crucial for navigation, especially in the uncharted waters of the New World.

What is the study of celestial bodies?
Astronomy is the study of celestial bodies, such as stars, planets, galaxies, and other objects in the universe. Astronomers use observations and scientific principles to understand the nature, composition, and behavior of these objects.
What scientist studies physical properties of celestial bodies?
An astronomer or an astrophysicist studies the physical properties of celestial bodies such as stars, planets, galaxies, and other objects in the universe. They use observations, mathematical models, and data analysis to understand the behavior and characteristics of these objects.
What describes a specific location in space?
A specific location in space can be identified by its coordinates, which can include its distance from a reference point and its direction relative to other objects. Astronomers often use celestial coordinates such as right ascension and declination to pinpoint the location of celestial objects in the sky.
What are the tools scientist use observe objects in the night sky?
Scientists use telescopes, such as optical telescopes, radio telescopes, and space telescopes, to observe objects in the night sky. They also use instruments like spectrographs and cameras to analyze the light from celestial objects and gather data for research and study.
What person studies the heavens?
An astronomer studies the heavens, including stars, planets, galaxies, and other celestial objects. They use telescopes and other instruments to observe and analyze these celestial bodies to better understand the universe.
What navigational tools did Cortes use?
He used celestial objects and compass.
How do astronomers use the celestial sphere to plot a star's exact positions?
Astronomers use celestial spheres and mathematical equations to approximate the distances between the star and other celestial objects.

How do you use the word bodies in a sentence meaning objects such as stars and asteroids?
The celestial bodies are especially bright on a cool, clear night.
What do astronomers use to describe location of objects in the sky?
Astronomers use a system of coordinates to describe the location of objects in the sky, similar to how latitude and longitude work on Earth. The primary system is the equatorial coordinate system, which includes right ascension and declination. Right ascension is akin to longitude and measures the angle along the celestial equator, while declination, similar to latitude, indicates how far north or south an object is from the celestial equator. This system allows astronomers to pinpoint celestial objects accurately.

What is an artificial construct that astronomers use to map the heavens?
Astronomers use coordinate systems like equatorial and ecliptic coordinates to map the heavens. These systems help astronomers locate and study celestial objects by providing a framework for referencing positions in the sky.
What tools astronmer use?
Astronomers use telescopes (like optical, radio, and space telescopes), spectrographs to study light from celestial objects, cameras to capture images, computers for data analysis and simulation, and specialized software for mapping the sky, tracking celestial objects, and creating models of the universe. They also rely on satellites, spacecraft, and ground-based observatories for their research.
