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.
it works by measureing electromagnetic waves given by stars
They use spectroscopy.
Using spectroscopy we can determine much about a planet's atmosphere.
It orbits a planet or other body. Satellites are orbiters. Usually the orbiter collects data about the body it is orbiting. This can involve photography, spectroscopy, etc.
It is spectroscopy.
The study of high-energy, electromagnetic radiation, which includes x-rays, is called atomic spectroscopy. The study of nuclear radioactivity and decay is called nuclear physics. For the study of electromagnetic radiation of energies below x-rays you have: UV - UV spectroscopy Visible Light - gaffer Infra-red - infrared spectroscopy Microwave - microwave spectroscopy Radio - amateur broadcaster
Laser spectroscopy studies the effects of lasers on molecules. The main purpose of laser spectroscopy is to learn more about the reactions of molecules to light, and how this can aid in development of light-sensitive technology.
Telescopes, spectroscopy, and a "Voyager" space probe.
The utilization of photo-ionization and kinetic energy distribution analysis of emitted photoelectrons to study the electronic state and composition of the surface region of a sample is known as photoelectron spectroscopy. This technique can be subdivided into two areas: X-ray photoelectron Spectroscopy and Ultraviolet Photoelectron Spectroscopy.
Spectroscopy is basically the study of the spectrums of visible and non-visible light rays. Specifically, it is determining the output of radiation an object has along the spectrum. This is called a wavelength.

no,it is reflection spectroscopy
Spectroscopy originated through the study of visible light dispersed by a prism according to its wavelength. An instrument called a spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.
