How did Edwin Hubble's discovery that the Andromeda galaxy was far away of our own galaxy contribute to astronomers' knowledge about the size of the universe?
Prior to Hubble's discovery scientists generally believed that our galaxy was the entire universe. Hubble found that the Andromeda galaxy was, then called the Andromeda Nebula, was not a part of our galaxy but a galaxy unto itself far beyond the edge of the Milky Way. This discovered demonstrated that the universe is much larger than scientists have believed.
Are smaller stars closer to earth?
No, but because small stars emit less light than large ones, they are only visible to the naked eye at comparatively "short" distances in interstellar terms while larger, brighter stars are visible at much greater distances.
What gives Hubble its excellent clarity its size or its position in space?
Above all the position in space, with the absence of a disturbing atmosphere, is the prime factor of the excellent pictures. This is also the reason why it was built at all. Of course, the larger the instrument the better for observations.
What are the types of distance units that astronomers use?
For small distances, e.g. Earth to Moon, scientists use miles of kilometers. For larger distances, e.g. the orbit diameter of Jupiter, they use the "AU" or Astronomical Unit, which is the distance from the Sun to Earth. For enormous distances, astronomers use the lightyear, which, although it sounds like a time unit, is truly a distance unit. A lightyear is the distance light travels in one year, or 5.87849981 × 1012 miles. Another unit for large distances is the Parsec, which is 3.26 lightyears.
Why are astronomical units necessary?
Because it would be impractical (very large numbers) to use kilometers, miles, or meters to measure distances in our solar system. This unit of measurement is used as it allows for comparisons to be done with relative ease, and all distances can be standardized. For this same reason when talking about anything outside of the solar system, light-years are used as the distances become drastically larger and too much for AUs to handle.
What is happening when your constant rate of change is posotive?
Whatever it is it's always increasing/becoming larger/higher
What is the characteristics of springs with large spring constant in hooke's law?
larger the spring constant of a spring, the more stiffer it is.
What is constant of variation in math terms?
It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.
What is the relationship between flow rate and pipe size?
At constant pressure and constant fluid density, larger pipe results in larger flow rate.
What does the spring constant k mean?
The spring constant is a measure of stiffness - the ability to resist displacement under a load. It is denoted by K where F = kx where f = load force and x = displacement
How does television improve life?
With a larger worldview and updates on what is happening. It also helps with bordom! ;)
How did Hubble make the universe larger?
The Hubble Space Telescope made the universe appear larger by providing us with high-resolution images of distant galaxies and other celestial objects. By capturing sharp and detailed images, Hubble revealed the immense distances and vastness of the cosmos, allowing us to see objects that were previously too faint or blurred to be observed. Its observations helped us understand the true scale and size of the universe.
What is happening to the distance between galaxies because of the big bang?
The distance is getting larger as the universe expands.
Equation for a circle centered at the origin should one increase to make a circle larger?
Yes, increase the constant term to make the circle larger.
Are satellites better than hubble telescope?
"Better" at doing WHAT, exactly? First, the Hubble Space Telescope _IS_ a satellite. It was the first large astronomical telescope placed in orbit. Since then, other larger ones have been launched, but the Hubble itself has been a great asset to astronomy. Second, the HST has a few specific purposes. It doesn't aid in weather forecasting, it cannot relay telephone calls and it doesn't broadcast TV programs to your dish, which are things that other satellites CAN do. But other satellites can't do what the Hubble does, or as well.
Why are elevations drawn so vertically exaggerated that they appear many times larger than distances?
Otherwise you might not notice them.
What space vehicles were used in hubble telescope mission'?
Space Shuttles Discovery and Atlantis were most often used for HST Servicing Missions, due to their larger cargo bays.
