What are the characteristics of stars and how are they observed using telescopes?
Understand the Problem
The text is discussing the characteristics of stars, including their size, brightness, and composition. It also mentions famous telescopes used for viewing stars, particularly the Hubble Space Telescope. This indicates a focus on astronomy.
Answer
Stars are characterized by size, brightness, color, temperature, and composition. Telescopes observe them across the electromagnetic spectrum.
Stars are characterized by size, brightness, color, temperature, and composition. They are observed using telescopes that detect various electromagnetic spectrum parts, providing information on their attributes through filters that highlight different wavelengths.
Answer for screen readers
Stars are characterized by size, brightness, color, temperature, and composition. They are observed using telescopes that detect various electromagnetic spectrum parts, providing information on their attributes through filters that highlight different wavelengths.
More Information
Different filters help discern the temperature of stars, as cooler stars appear brighter in the red spectrum, while hotter stars shine more brightly in blue or green.
Tips
A common mistake is to assume stars of the same color have identical temperatures or brightness. Use multi-spectral data to get accurate information.
