The Hubble effect, also known as Hubble's Law, describes the observation that galaxies are moving away from us, and their speed is proportional to their distance from Earth. This phenomenon is a key piece of evidence for the expanding universe theory, indicating that the universe has been expanding since the Big Bang. The relationship is expressed mathematically as ( v = H_0 \times d ), where ( v ) is the velocity of a galaxy, ( H_0 ) is the Hubble constant, and ( d ) is the distance to the galaxy. The Hubble effect provides crucial insights into the dynamics and evolution of the cosmos.
What affects does the HST really have on society?
The Harmonized Sales Tax (HST) can have several impacts on society. Primarily, it simplifies the tax system by merging provincial sales tax with the Goods and Services Tax (GST), which can reduce administrative costs for businesses. However, it often leads to higher prices on consumer goods and services, disproportionately affecting low- and middle-income households. Additionally, the revenue generated can enhance public services and infrastructure, which can benefit society as a whole.

The Hubble Space Telescope orbits the Earth at an average altitude of about 347 miles (560 kilometers) and travels at a speed of approximately 17,500 miles per hour. This translates to roughly 4.86 miles per second. This high speed allows Hubble to complete an orbit around the Earth approximately every 95 minutes.
Where is secondary mirror on Hubble telescope?
The secondary mirror of the Hubble Space Telescope is positioned in front of the primary mirror, mounted on a support structure called the "spider." It reflects light collected by the primary mirror towards the telescope's instruments. This configuration allows Hubble to focus and capture detailed images of astronomical objects. The secondary mirror's placement is crucial for the telescope's overall optical performance.
What organization launched Hubble space telescope?
The Hubble Space Telescope was launched by NASA in collaboration with the European Space Agency (ESA). It was deployed into low Earth orbit aboard the Space Shuttle Discovery on April 24, 1990. The telescope has since provided invaluable astronomical data and stunning images, significantly advancing our understanding of the universe.
What is the objective focal length of the hubble space telescope?
The objective focal length of the Hubble Space Telescope is approximately 57.6 meters (or 188 feet). This long focal length allows Hubble to capture high-resolution images of astronomical objects, making it one of the most powerful space telescopes. The design includes a primary mirror with a diameter of 2.4 meters, which contributes to its ability to observe in various wavelengths, including visible, ultraviolet, and near-infrared light.
The Hubble Space Telescope is named after the American astronomer Edwin Hubble, who made significant contributions to our understanding of the universe in the early 20th century. His observations led to the discovery of the expanding universe and the formulation of Hubble's Law, which describes the relationship between the distance of galaxies and their redshift. The telescope was launched in 1990 and has since provided invaluable data, furthering astronomical research and our knowledge of the cosmos.
The Hubble Space Telescope cannot see objects that are too close to Earth, such as the surface of the Moon or other nearby planets, due to its design and the distortion caused by Earth's atmosphere. It also struggles with observing objects in the infrared spectrum, which is important for seeing through dust clouds in space. Additionally, Hubble cannot observe in certain wavelengths, like radio or some parts of the ultraviolet spectrum, limiting its ability to study specific celestial phenomena. Lastly, its operational limitations prevent it from capturing images of very faint or distant objects that require more sensitive instruments.
What did Edward Hubble discover about galaxies at Mr Wilson observatory in 1929?
In 1929, Edwin Hubble discovered that galaxies are moving away from us and that their speed is proportional to their distance, a phenomenon known as Hubble's Law. This groundbreaking finding provided strong evidence for the expansion of the universe and led to the understanding that the universe is not static but dynamic. His work at the Mount Wilson Observatory helped establish the field of extragalactic astronomy and fundamentally changed our perception of the cosmos.
