18 Facts About Stellar astronomy
2.
Theoretical Stellar astronomy seeks to explain observational results and observations are used to confirm theoretical results.
| FactSnippet No. 1,009,783 |
3.
In early historic times, Stellar astronomy only consisted of the observation and predictions of the motions of objects visible to the naked eye.
| FactSnippet No. 1,009,784 |
4.
Particularly important early development was the beginning of mathematical and scientific Stellar astronomy, which began among the Babylonians, who laid the foundations for the later astronomical traditions that developed in many other civilizations.

5.
Greek Stellar astronomy is characterized from the start by seeking a rational, physical explanation for celestial phenomena.
| FactSnippet No. 1,009,786 |
6.
Stellar astronomy's work was defended by Galileo Galilei and expanded upon by Johannes Kepler.
| FactSnippet No. 1,009,787 |
7.
Significant advances in Stellar astronomy came about with the introduction of new technology, including the spectroscope and photography.
| FactSnippet No. 1,009,788 |
8.
Theoretical Stellar astronomy led to speculations on the existence of objects such as black holes and neutron stars, which have been used to explain such observed phenomena as quasars, pulsars, blazars, and radio galaxies.

9.
Radio Stellar astronomy uses radiation with wavelengths greater than approximately one millimeter, outside the visible range.
| FactSnippet No. 1,009,790 |
10.
Radio Stellar astronomy is different from most other forms of observational Stellar astronomy in that the observed radio waves can be treated as waves rather than as discrete photons.
| FactSnippet No. 1,009,791 |
11.
Infrared Stellar astronomy is founded on the detection and analysis of infrared radiation, wavelengths longer than red light and outside the range of our vision.
| FactSnippet No. 1,009,792 |
12.
Ultraviolet Stellar astronomy is best suited to the study of thermal radiation and spectral emission lines from hot blue stars that are very bright in this wave band.
| FactSnippet No. 1,009,793 |
13.
Gamma ray Stellar astronomy observes astronomical objects at the shortest wavelengths of the electromagnetic spectrum.
| FactSnippet No. 1,009,794 |
14.
Gravitational-wave Stellar astronomy is an emerging field of Stellar astronomy that employs gravitational-wave detectors to collect observational data about distant massive objects.
| FactSnippet No. 1,009,795 |
15.
Some widely accepted and studied theories and models in Stellar astronomy, now included in the Lambda-CDM model are the Big Bang, dark matter and fundamental theories of physics.

17.
One branch of amateur Stellar astronomy, astrophotography, involves the taking of photos of the night sky.
| FactSnippet No. 1,009,798 |
18.
The pioneer of amateur radio Stellar astronomy was Karl Jansky, who started observing the sky at radio wavelengths in the 1930s.
