The Little Dipper, a constellation in the northern sky, is important for navigation and stargazing. It is part of the Ursa Minor constellation and contains the North Star (Polaris), which is a crucial reference point for finding direction. Astronomers and skywatchers often use the Little Dipper to locate other stars and constellations.

This question is surely one of the most intractable mysteries of our time.

There has been no city there within recorded human history. In fact, there are not

many places on Earth that are farther away from any land in any direction. And yet,

this same question keeps popping up here on WikiAnswers. It's as if some class of

student Flying Dutchmen have been condemned by some ghostly geography teacher

to sail throughout eternity, searching for a port into which to put (??), in a place where

land can never be found.

40°S/80°E does the job nicely. That point is far out in the Indian Ocean, surrounded by

a vast expanse of seawater in every direction. It's about 2,070 miles southwest of Perth,

1,940 miles north of the Antarctic coast, 3,250 miles south of Colombo, and 2,820 miles

southeast of Durban.

no one knows and i need the real answer fast

Surprisingly little. Water covers a little under three-quarters of Earth's surface, but it's almost all on (or just below) the surface, so a relatively tiny fraction of Earth is water.

The sun doesn't move; earth does. The Earth slowly rotates until the side the sun was facing is now away from the sun.

Example: If the sun is shining on Florida at noon-sunset, the earth rotates slowly in that time until Florida is facing away from the sun and so it is night in Florida and day on the other side of the earth.

NASA was officially established on July 29, 1958, but its roots trace back to the National Advisory Committee for Aeronautics (NACA) founded in 1915. Therefore, it took around 43 years to transition from NACA to NASA.

Silica is widely present, indeed dominant, in our Earth's crust, and it also has a great propensity to crystallize. These factors thus produce thousands of silicate minerals.

Nowadays, a silicate process is used to produce the majority of our magnesium.

In the future, there are possibilities that silicon refined from sand may be transported to become a fuel for energy production.

THey obtain energy by eating consumers and producers.

The most common gas in nebulae is hydrogen. Hydrogen makes up about 90% of the atoms in the universe and is the building block for stars and galaxies. It emits light in the red part of the spectrum, creating the characteristic pink or red glow of many nebulae.

The moon is estimated to have formed around 4.5 billion years ago, shortly after Earth. It first appeared in the sky as a result of a giant impact between Earth and a Mars-sized body, leading to the debris coalescing to form our natural satellite.

Mercury and Venus would likely have the most extreme temperature differences between their day and night sides due to their lack of atmosphere and proximity to the Sun. Additionally, tidally-locked exoplanets, where one side always faces their star, could also experience vast temperature variations depending on their distance from the star.

The latitude that best represents the location where the Sun is directly overhead at noon on April 27 is the Tropic of Cancer, which is at approximately 23.5 degrees north. This is because on April 27 the Sun is positioned directly over the equator during the spring equinox.

well the sun is about 99.9% of the total mass in our solar system. it's gravitational pull stops our planet and all the other planets and everything else in the solar system drifting out into space. the sun's light& heat lets life live on this planet.

Fusion is the main energy source for stars. It is the process by which stars convert hydrogen into helium through nuclear reactions, releasing a tremendous amount of energy in the process. Fission, on the other hand, involves the splitting of atomic nuclei and is not the primary energy source for stars.

Very nice one......

1. The astronomers predict the distance between us and star.

2. The astronomers predict the age of star.

3. By noticing the intencity of light they predict the star is going away or coming near.

Yes, dawn is the time of day that occurs before sunrise when the sky starts to lighten but the sun is still below the horizon. It is often characterized by a soft glow and the gradual emergence of light.

The moon's orbit around Earth helps stabilize our planet's rotation and axis, leading to stable climate conditions. Additionally, the moon's gravitational pull causes tides in Earth's oceans, which play a crucial role in marine ecosystems. The moon also impacts cultural practices, such as calendars and religious events.

No, Titan is actually a moon of Saturn, not Jupiter. It is the second-largest moon in our solar system and is known for its thick atmosphere and lakes of liquid methane and ethane on its surface.

The speed of a star affects its spectrum through the Doppler effect. If a star is moving towards or away from us, the wavelengths of the light it emits will be shifted towards the blue (blue shift) or red (red shift) end of the spectrum, respectively. This shift can provide information about the star's velocity and direction of motion.

The force that keeps a comet in orbit around a larger celestial body, like the sun, is gravity. The gravitational pull between the comet and the larger body keeps the comet moving in a curved path around it.

Animals that are commonly found in mild forest lands include deer, squirrels, rabbits, birds (such as woodpeckers and robins), raccoons, and foxes. These animals have adapted to the temperate climate and diverse vegetation of mild forest ecosystems.

The Earth is mainly covered in water, even more than land. when seen from space, Earth is mostly blue because of the oceans, ans so is called the blue planet. this is also from the fact that we are the only planet in the solar system that can support life, because we have drinking water.

To convert inches of Hg to atmospheres, you can use the conversion factor: 1 atm = 29.92 inches of Hg. Thus, 36.5 inches of Hg is equal to approximately 1.22 atm.

For the same reason that the earth's distance from the sun is always changing. The orbits are elliptical and not circular. Virtually all orbits in the solar system are elliptical, Pluto's being the most extreme of the major and minor planets. Some of the moons come close to having no eccentricity.

Water has been present on Earth for billions of years, since the planet's formation. The water cycle continuously recycles and redistributes water on Earth, ensuring its existence. As long as Earth maintains the conditions needed to support life, water will continue to be a fundamental element on our planet.
