Hertzsprung-Russell Diagram
The Hertzsprung-Russell diagram is a graphical tool that astronomers use to classify stars based on their brightness (luminosity) and temperature (color). Stars are plotted on a two-dimensional chart, with temperature decreasing from left to right and brightness increasing vertically. This diagram reveals patterns, such as the main sequence where most stars, including our Sun, are found. It also highlights other categories like giants and white dwarfs, helping scientists understand stellar evolution—how stars form, live, and ultimately end their lives. Overall, it provides essential insights into the nature and lifecycle of stars.

The Hertzsprung-Russell Diagram (HR Diagram) is a powerful tool in astronomy that graphs stars based on their brightness (luminosity) and temperature. On the diagram, stars are classified into distinct groups: main sequence stars (where most stars, including the Sun, reside), giants, and white dwarfs. The horizontal axis shows temperature, decreasing from left to right, while the vertical axis represents brightness, increasing upward. This visual representation helps scientists understand the life cycle of stars, their evolutionary stages, and relationships between their characteristics. Overall, it illustrates the connection between a star's temperature and its luminosity.

The Hertzsprung-Russell Diagram (H-R Diagram) is a graphical representation that shows the relationship between stars' brightness, color, and temperature. It typically features temperature on the horizontal axis and luminosity (or brightness) on the vertical axis. Stars fall into distinct groups, like the main sequence, where most stars, including our Sun, reside. Above and below this line are giants and supergiants, along with white dwarfs. The H-R Diagram helps astronomers understand stellar evolution, revealing how stars change over time and how they are categorized based on their physical properties.
