In modern academic writing, the Sun symbol is used for astronomical constants relating to the Sun. Teff☉ represents the solar effective temperature, and the luminosity, mass, and radius of stars are often represented using the corresponding solar constants ( L☉, M☉, and R☉, respectively) as units of measurement.
It is one of the most important and widely used diagrams in astronomy, with applications that extend far beyond the purposes for which it was originally developed more than a century ago. It is customary to plot H–R diagrams in such a way that temperature increases toward the left and luminosity toward the top.

Data science is diligently being used in the field of astronomy and here’s how-. Use of data science in astronomy can be largely found in the concept of data-driven astronomy (DDA). It is the production of astronomical knowledge based on archival data sets. DDA is similar to industrial data science in a way that the data sets are not taken ...
When there are no nearby stars to use as a reference, lasers are used to generate small bright spots in the sky. These laser guide stars can be used by astronomers with adaptive optics imaging to ...
