Galaxies

Yes. Objects deeper in a gravity well see things further away as moving faster; likewise, objects far away see objects deep in the well moving more slowly.

This has real consequences here on Earth: a plane flying high in the sky is in a shallower region of Earth's gravitational well, while a ground station is deeper. We can place perfectly synchoronized clocks on the station and on the plane, and send the plane round the world, and actually see that the clocks have shifted out of sync.

The diameter of the local group, which is a cluster of galaxies that includes the Milky Way, is estimated to be around 10 million light-years. This means that from one end of the local group to the other, it spans a distance of approximately 10 million light-years.

The more spectral lines of a star are shifted to the red end of the spectrum, the more it indicates that the star is moving away from us. This phenomenon is known as redshift, and it is a result of the Doppler effect caused by the expansion of the universe.

We cannot see the center of the Milky Way Galaxy because of the dense clouds of dust and gas in the way, but there are interesting indications that our galaxy, like many large galaxies, may contain a supermassive black hole in its center.

The star Polaris is at the tip of the handle of the little dipper or Ursa Minor. Kochab is at the end of the ladle.

The bright center of a distant galaxy is likely a supermassive black hole. The friction and collision of material spiraling around the black hole generates high temperatures and intense light emissions, making it appear bright from afar. This process is known as "accretion" and is a key feature of active galactic nuclei.

The longest day on earth is called the summer solstice. It occurs around June 21st in the Northern Hemisphere and around December 21st in the Southern Hemisphere. On this day, the North Pole is tilted closest to the sun, resulting in the longest period of daylight of the year.

Total solar eclipses are much less frequent because it is much more likely that part of a planet/moon/satellite gets partly in our way of the sun than a planet/moon/satellite gets 100% in our way.

This is a difficult question to answer, like many things in science. We know they exist, but we wonder why.

Gravity exists, we roughly know how it works and its effects, why it exists? It just does. It happened to be a part of the laws of physics put into motion once the universe formed.

Radiation as it is commonly thought of, for example alpha radiation, is given off by the decay of certain elements. Radon gas is radioactive, thus it decays slowly to a more stable state and in doing so it releases charged particles - alpha.

We know things happen, we know how they happen and can predict when.

What we really will never know (probably) is why.

The spectral lines of galaxies are redshifted, indicating that they are moving away from Earth. This redshift is typically a result of the expansion of the universe, causing galaxies to move further apart.

It is the Sagittarius Dwarf Galaxy. The Canis Major Dwarf Galaxy is the second closest to the milky way.

Ed Conrad is a layman who in the early 1980s discovered some rocks in a coal field which he believes are human skulls which date back 280 million years or so, 200 million years before modern science claims that man evolved. These rocks have been examined by scientists, including those at the Smithsonian Institute, who have reported that the rocks are just rocks and not of human origin, but Conrad persists in believing there is a mass conspiracy among anthropologists and paleontologists to keep it secret as to when man actually first appeared on Earth. He posts regularly in several Usenet news groups devoted to the origins of man, frequently changing his username to get around the filters that people set to avoid his posts.

A globular cluster is a dense group of old stars within a galaxy that have formed a gravity bound spherical shape. They are composed of hundreds of thousands of stars that orbit the center of the galaxy together as a unit. We we don't know a lot about them. There are between one and two hundred globular clusters in the Milky Way, and thousands in very large galaxies, all hanging out around the galactic core.

Wikipedia has more information, and a link posted below will take the curious reader over there. Why not drop by and look at the picture of Messier 80 that was put up by our friends?

The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way, located about 2.5 million light-years away. It is home to about a trillion stars and has a diameter of approximately 220,000 light-years. Andromeda is on a collision course with the Milky Way and is expected to merge with our galaxy in about 4 billion years.

Most stars are composed primarily of hydrogen and helium, with hydrogen making up about 75% of their mass and helium about 25%. The remaining elements in stars are present in trace amounts, including carbon, oxygen, nitrogen, and other heavier elements.

They are categorized as "dwarf planets" now, leaving only 8 regular planets in our solar system. The names of all the dwarf planets are:
Ceres
Pluto
Haumea
Makemake
Eris

When a blue star blows up t is called a supernova, which eventually leads into the formation of a black hole. Although a regular star, say our sun, doesn't blow up, it turns into a huge super giant, it grows 5X its normal size and it will either gulp earth up, or burn us to death, but don't worry, that won't happen for a couple billion years, but not so good for your Great Great Great Great Great Great Great Great Great [could go forever] grand children :D

milky way is made up of dust and matter. these are the base and when combine, they form stars, planets. matter is antimatter and black matter, which is hence the createrand the destroyer or the god matter

With the average distance or "mean" distance from the Earth to the sun set at approximately 93,000,000 miles, and the speed of light at about 186,000 miles per second; the time in seconds it takes sunlight to reach the earth is appoximately "500 seconds". Most people refer to the time in minutes which would be about 8.333333 minutes.

Not "galaxies", just one galaxy. Our galaxy is called the Milky Way.

Several thousands of meteors hit the Earth each day. Most of them are the size of a grain of rice or smaller. A few each day may be the size of a baseball or occasionally the size of a basketball.

Once a week or so, the Earth is hit by a rock the size of a car, and once every few months, we get hit by something the size of a house. A couple of months ago, a meteor the size of a house exploded over central Indonesia; it scared a lot of folks, but apparently did no damage.

The VAST majority of these burn up completely in the atmosphere, surviving as nothing but dust. A few do make it to the Earth, often in small (fist-sized) chunks. Very few do any damage. Only a few people are known to have been hit by a meteorite; there was a boy in Germany last year who was struck in the hand by a meteorite the size of a pea. And how would you have liked to explain to YOUR insurance company that your new car was destroyed when a meteorite punched down through the roof and buried itself in your driveway? It happened!

Every few hundred years, bigger things hit the Earth, and some do a lot of damage. In 1908, a meteor or small comet exploded high in the atmosphere near a place called Tunguska, Siberia, causing an explosion the size of a nuclear bomb. 5000 years ago, a meteor struck in the Indian Ocean causing a tsunami, which may be the source of the "Great Flood" legends in Gilgamesh and Noah's Ark. 14000 years ago, something hit northern Canada causing the "Younger Dryas" mini-ice age.

It's called a "meteoroid" when it is out in space. When it enters the Earth's atmosphere and is heated to incandescence, the bright streak of light is called a "meteor".

If the object survives the fiery passage through the atmosphere and hits the ground, it is called a "meteorite".

We are not currently aware of any specific meteoroids or asteroids that are on a path to hit the Earth.

"NGC" in Xilinx refers to the Xilinx-specific netlist format used for implementing custom logic in Xilinx FPGAs. NGC files contain the design information and constraints necessary for synthesis and implementation in Xilinx tools. These files are generated from HDL-based designs during the synthesis process.
