The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
A camera designed to record astronomical objects (e.g., stars, planets, nebulae, galaxies) and their spectra.
Generally, a mirror used instead of lenses in astronomical and space applications. It is not limited in size, does not absorb UV or IR radiation, and is usually made aspheric to reduce aberrations. However, a spherical mirror can be used if it is...
An instrument that photographs the spectra of an extraterrestrial object.
The process of using a spectrograph with a telescope to acquire information on an astronomical object's speed and physical characteristics.
An instrument used to observe celestial bodies. Larger astronomical telescopes use mirrors instead of refracting lenses.
balloon-borne astronomical system
Any instrument or system carried by a balloon to the upper atmosphere to measure and record atmospheric information, such as radiation observations, while reducing atmospheric interference.
Keplerian astronomical telescope
A simple form of astronomical telescope that uses a fixed objective and a focusable eyepiece. The objective forms an intermediate image in the instrument, resulting in an image that appears upside down when viewed through the eyepiece.
