What have scientists learn with the hubble telescope?

Scientists have used the Hubble Space Telescope to make numerous groundbreaking discoveries, including the expansion rate of the universe, the age of the universe, and the existence of supermassive black holes. Hubble has also provided detailed images of distant galaxies, nebulae, and planets within our own solar system, leading to a better understanding of the cosmos.


What can scientists learn from a stars light?

Scientists can learn a star's composition, temperature, and age by analyzing its light. By studying the spectrum of light emitted by a star, scientists can identify the elements present in the star, determine its surface temperature, and estimate its age based on its brightness and color.


Is it true that scientists can learn about the chemical composition of stars by analyzing the light they transmit?

Yes, scientists can analyze the light emitted by stars, known as stellar spectra, to learn about their chemical composition. By studying the absorption and emission lines in the spectrum, scientists can identify the elements present in the star and their relative abundances. This information helps astronomers understand the processes happening within stars and how they evolve over time.


What did scientists learn by studying the rocks astronauts brought back from the moon?

Scientists learned important information about the moon's formation, history, and composition by studying the rocks brought back by astronauts. They found that the moon is much older than previously thought, provided evidence of past volcanic activity, and discovered similarities between moon rocks and certain rocks on Earth.
