An astronomical instrument is a device for observing, measuring, or recording astronomical data. [citation needed] They are used in the scientific field of astronomy, a natural science that studies celestial objects and the phenomena that occur in the cosmos, with the object of explaining their origin and evolution over time.

The Star-Spectroscope of the Lick Observatory in 1898. Designed by James Keeler and constructed by John Brashear.. Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, ultraviolet, X-ray, infrared and radio waves that radiate from stars and other celestial objects.
Astronomers use astrometric techniques for the tracking of near-Earth objects. Astrometry is responsible for the detection of many record-breaking Solar System objects. To find such objects astrometrically, astronomers use telescopes to survey the sky and large-area cameras to take pictures at various determined intervals.
Is the universe homogeneous and isotropic at sufficiently large scales, as claimed by the cosmological principle and assumed by all models that use the Friedmann–Lemaître–Robertson–Walker (FLRW) metric, including the current version of the ΛCDM model, or is the universe inhomogeneous or anisotropic?
Tools aboard the probe will collect data on the energy flowing out from the star, Rayl said. Research like this is integral because so much of life on Earth is dependent on the sun, she added.

Going clockwise, items include Cheese spread, Creamed spinach, crackers, beef steak, candy coated peanuts, and shortbread cookies Food and tray from the Skylab era (1973–74)
The Millennium Run, or Millennium Simulation (referring to its size [1] [2]) is a computer N-body simulation used to investigate how the distribution of matter in the Universe has evolved over time, in particular, how the observed population of galaxies was formed.
