This article is a list of notable unsolved problems in astronomy. Problems may be theoretical or experimental. Theoretical problems result from inability of current theories to explain observed phenomena or experimental results. Experimental problems result from inability to test or investigate a proposed theory.
[3] [4] [5] Based on strict dictionary definitions, "astronomy" refers to "the study of objects and matter outside the Earth's atmosphere and of their physical and chemical properties", [6] while "astrophysics" refers to the branch of astronomy dealing with "the behavior, physical properties, and dynamic processes of celestial objects and ...
Chaisson’s research and writing have won several awards, such as the 1977 B.J. Bok Prize [19] for “original radio-astronomy discoveries,” the 1980 Smith-Weld Prize [20] for “best article by a Harvard faculty member,” a 1990 (and 1994) certificate of recognition from NASA with U.S. flag flown aboard the Space Shuttle-31 mission for “exceptional performance on the Hubble Space ...

Magnitude values do not have a unit. The scale is logarithmic and defined such that a magnitude 1 star is exactly 100 times brighter than a magnitude 6 star. Thus each step of one magnitude is 100 5 ≈ 2.512 {\displaystyle {\sqrt[{5}]{100}}\approx 2.512} times brighter than the magnitude 1 higher.
The solar apex is in the constellation of Hercules near the star Vega. [1]For more than 30 years before 1986 the speed of the Sun towards the solar apex was taken to be about 20 km/s [2] but all later studies give a smaller component in the vector toward galactic longitude 90°, reducing overall speed to about 13.4 km/s.

Stellar parallax is so difficult to detect that its existence was the subject of much debate in astronomy for hundreds of years. Thomas Henderson , Friedrich Georg Wilhelm von Struve , and Friedrich Bessel made the first successful parallax measurements in 1832–1838, for the stars Alpha Centauri , Vega , and 61 Cygni .
