What are the contributions of Edwin Hubble?
Edwin Hubble made significant contributions to astronomy, most notably through his discovery of the expansion of the universe, which led to Hubble's Law. He demonstrated that distant galaxies are moving away from us, with their speed proportional to their distance, providing strong evidence for the Big Bang theory. Hubble also played a crucial role in classifying galaxies and establishing the field of extragalactic astronomy. His work fundamentally changed our understanding of the universe and its structure.
Why does the hubbie telescope produce clearer images than a telescope of the same size on earth?
The Hubble Space Telescope produces clearer images than ground-based telescopes of the same size primarily because it operates outside of Earth's atmosphere. The atmosphere can distort light from celestial objects due to turbulence and varying densities, which causes blurring and reduces image clarity. Additionally, Hubble can capture a broader range of wavelengths, including ultraviolet light, which is absorbed by the atmosphere. This combination allows Hubble to achieve higher resolution and clearer images.
How did Edwin hubble prove other galaxies exist?
Edwin Hubble proved the existence of other galaxies by observing the redshift of light from distant celestial objects. In the 1920s, he analyzed the spectra of these objects and discovered that their light was redshifted, indicating they were moving away from us. By correlating the redshift with their distances, Hubble established the relationship known as Hubble's Law, demonstrating that the universe is expanding and that these distant, redshifted objects were indeed separate galaxies beyond the Milky Way. This groundbreaking work fundamentally changed our understanding of the universe's structure.
Is the hubble telescope the biggest telescope ever built?
No, the Hubble Space Telescope is not the biggest telescope ever built. While it is one of the most powerful and well-known space telescopes, it has a 2.4-meter (7.9-foot) primary mirror. The largest optical telescope currently is the Gran Telescopio Canarias, which has a mirror measuring 10.4 meters (34 feet) in diameter. Additionally, the future Extremely Large Telescope is expected to have a mirror larger than 39 meters (128 feet).
How do astronomers solve problems using telescopes on earth?
Astronomers use telescopes on Earth to collect and analyze light from celestial objects, which allows them to study their properties, such as composition, distance, and motion. By employing various types of telescopes—optical, radio, and infrared—they can observe different wavelengths of light, revealing information that might not be visible to the naked eye. Advanced imaging and spectroscopy techniques enable astronomers to resolve complex problems, such as mapping star formation in galaxies or detecting exoplanets. Additionally, ground-based telescopes are often equipped with adaptive optics to compensate for atmospheric distortions, enhancing the clarity and detail of observations.

Despite these challenges, Hubble has made significant contributions to astronomy, providing invaluable data and stunning imagery of the universe.
Why does the hubble see better than ground-based telescopes?
The Hubble Space Telescope sees better than ground-based telescopes primarily because it operates above Earth's atmosphere, which can distort and absorb light. This atmospheric interference causes blurring and limits the clarity of images taken from the ground. Additionally, being in space allows Hubble to avoid light pollution and weather-related disruptions, providing clearer, more detailed observations of celestial objects.
What evidence did Hubble base his thinking on?
Edwin Hubble based his thinking on several key pieces of evidence, notably his observations of distant galaxies and their redshifts. He discovered that most galaxies are moving away from us, with their light shifted to longer wavelengths, indicating an expanding universe. This led him to formulate Hubble's Law, which correlates the distance of a galaxy with its recessional velocity. His findings challenged the prevailing view of a static universe and provided crucial support for the Big Bang theory.
What type of scientist built Hubble space telescope?
The Hubble Space Telescope was primarily designed and built by a team of astronomers and engineers, with significant contributions from astrophysicists. The project was led by NASA and the European Space Agency, involving specialists in optics, instrumentation, and spacecraft design. Notably, astronomer Edwin Hubble's work in the 1920s laid the foundational concepts for the telescope, which was named in his honor.
What two measurements are required to determine the Hubble constant?
To determine the Hubble constant, two key measurements are required: the distance to a galaxy and its redshift. The distance can be obtained using various methods, such as the cosmic distance ladder, while the redshift is measured through the light spectrum emitted by the galaxy, indicating how fast it is moving away from us due to the expansion of the universe. By plotting these values, astronomers can calculate the Hubble constant, which describes the rate of this expansion.
