A banana cannot be used to study the celestial bodies.
The main purpose of sending magnetometers to other planets is to measure the magnetic field of other celestial bodies. Vector magnetometers were first used on interplanetary craft in 1988.
An astrolabe is an old instrument used to calculate the position of celestial bodies. Here are some sentences.I found an antique astrolabe in an old store.An astrolabe was used before the sextant was invented.Polish that astrolabe so it doesn't tarnish.
"Celestial" means "heavenly", or of the stars. Technically the word "celestial" should not be applied to things within our solar system; these things should be referred to as "planetary". However, the term "celestial" is often used to refer to anything outside of the Earth.
celestial navigation LIAR!
Spectroscopy is the systematic study of spectra and spectral lines. Spectral lines are used to provide evidence about the chemical composition of distant objects. So the answer to your question is through spectroscopy.. not spectrometry like the previous editor posted.
The Maya studied astronomy, calendrics, agriculture, and the movements of celestial bodies from observation. They built impressive observatories and used their knowledge to develop sophisticated calendars and accurately predict celestial events.
Telescope
An observatory is a location used for observing terrestrial and/or celestial events
nearly all heavenly bodies that can observed by the naked eye can be used for navigation.... assuming you can identify the body of course!
They form the next generation of stars and planets.
Mountains. Celestial bodies were thought to be perfectly spherical before that.
The term Astrology is currently used to be indicate a very ancient "system" used to identify human personality types and the behaviors expected within each "sign", consequent to the influence of planetary energies on personality elements, such as the rational processes, the emotional patterns, or the subconscious motivators. In time, the study of the observable planets and other celestial bodies switched focus from the affects of planetary energies on human behavior to the "scientifically measurable" characteristics of these bodies themselves, their origins, and their relative influence on the dynamics of other celestial bodies. We call this Astronomy.
buildings to study Astronomy
The main astronomical instruments are the armillary sphere, the triquetrum, the quadrant, the astrolabe, and the various kinds of telescopes. These instruments are all used to observe, measure, and study celestial bodies. They can be used to collect data on planets, galaxies, radiation, stars, nebulas, etc.
A spectrometer.
Spectrograph.
An armillary sphere is an instrument consisting of graduated metal circles used to represent the motions of celestial bodies around the earth.
