How does the diameter of the disk of the Milky Way Galaxy compare to its thickness?
The Milky Way galaxy is 100,000 light years across and 1,000 light years thick.
But the really fun part is that the Milky Way is all around us. We are right inside
the Milky Way; it is our home galaxy. The Milky Way is not far away from you.
You are a part of it.
How old is the Milky Way galaxy?
It's very difficult to define the age of the Milky Way Galaxy, but the age of the oldest star in the Galaxy yet discovered is estimated to be about 13.2 billion years.
The Universe is believed to be around 13.73 billion years old.
Not according to that theory (not really needed for this),
but the sun is about 5 billion years old (as is the whole solar system)
and Earth has an iron core - which we know came from prior stars (lots of them)
which gives us an other couple of billion years ...
so you come up with a minimum of about 10 billion years
(and a max of 13 ... which does come from "big bang calculations").
Is the Earth located in a spiral galaxy called the Milky Way?
The Earth and its parent star, the Sun, are located within the Milky Way galaxy, so named by the inhabitants of Earth. The Milky Way galaxy is believed to be a larger-than-average barred spiral galaxy. There may be as many as 300 billion stars in our Milky Way, maybe many more.
The nearest galaxy of such enormous class we have named the Andromeda galaxy. It is roughly 2.5 million light-years distant. But there are two tiny galaxies that orbit our own Milky Way; the Large Magellanic Cloud and the Small Magellanic Cloud. They are named for Ferdinand Magellan, the first white dude from the northern hemisphere to make a big noise about them.
The Earth is located in the "Orion arm" of our galaxy, somewhere between half and two-thirds of the way out from its hellish center. In a galaxy thought to be 100,000 light years across, we find ourselves in the lucky "habitable zone" of one of its spiral arms.
Why does your galaxy from your view not look like other sprial galaxies?
Good question; why can't you see your own face without using a mirror?
Answers to BOTH questions; because we're INSIDE our faces - and inside our galaxy - and we can't see the whole thing. From the astronomy perspective, it's even worse; imagine being a cell in one of your tonsils, and trying to see your entire body. Our Sun is about 2/3 of the way out one of the spiral "arms", and we can't see the whole thing.
How many stars are identified in your milky way galaxy and Andromeda?
We will never have any accurate answer, for several reasons.
1. We're inside the Milky Way, and there is at least a third of it that is hidden from view on the other side of the galactic core. Estimates as to the number of stars in our galaxy ranged up to 400 billion stars, but that was just a guess.
2. In the last year or so, the estimates have more than DOUBLED, because we now think that there are vastly more of the very small and dim "brown dwarf" stars. We now estimate that there may be a TRILLION stars in the Milky Way.
3. Andromeda is a very long way away; the only individual stars that can be seen are the few very brightest stars such as supernovas. But because Andromeda is, we think, even larger than the Milky Way, an estimate of a trillion stars is probably quite reasonable.
In what ways did industrialization turn workers into interchangeable parts?
Skilled craftsmen were replace by machinery that could be operated by anyone with a little training.
What do scientist think all of the stars in the milky way galaxy orbit around?
They orbit around the center of the galaxy due to the galaxy's own gravity. Contrary to popular belief, the Galaxy's central black hole does not have strong enough gravity to hold the entire galaxy together as it accounts for only a tiny fraction of our galaxy's mass.
Is the milky way considered a clump of stars?
No. It is a disk-shaped galaxy, like a pinwheel, with several curved radial arms and a large mass at the center.
The closest thing to a "clump" of stars are the so-called "globular clusters" which are more spherical in organization than other common galaxies.
How many Red Dwarf Stars are there in the Milky Way Galaxy that we know of in October of 2011?
The Milky Way has somewhere between 100 and 400 billion stars; most of those are red dwarf stars.
If God exists, why does God exist?
God does exist...The lord does exist. Besides....if you look at it from an outside perspective....Wouldnt you want to believe rather than not believe when it comes to judgment day? Is it really worth the gamble?
ANSWER:
Humans since evolution in their conscious awareness of existence assimilate concepts through senses as discrete tangible forms or in abstract notions to relate the discrete perceived in conscious/sub conscious state in the belief and conviction of existence of a concept or form.However abstract concepts too are conceptualized in relative forms as beliefs and convictions as faith in the existence of a void that created a primordial matter as discrete existence.The average human senses and his pseudo consciousness fails to format paradoxical concepts such as void and non existing into a discrete form. In his bio-psychological reaction tends to palisade in security in his own belief and conviction as faith in customs,rituals,doctrines,dogmas and his duty and obligations to that faith called religion. When the human bio-psychological conflicts becomes a doubt in his own beliefs and convictions emerge as fear that nothing exists(God).Those who have faith do not fear.
How many comets are in the milky way?
As of November 2009, astronomers had listed 3,648 known comets (580 unclassified). This is a small fraction of the number that could exist, which could be as high as a trillion or more. Most will never come into proximity of the Sun, trapped in orbits well beyond the planets of the solar system.
Do scientists still explore the Milky Way Galaxy and find new things?
Most of the observation astronomers make are inside our Galaxy. Of course we still find new things. The Milky Way is a very complex and diverse collection of celestial objects. We still have much to learn!
Kalpana Chawla's path to the 'Milky Way'?
Chawla joined the NASA Astronaut Corps in March 1995 and was selected for her first flight in 1996. She had traveled 10.67 million km, as many as 252 times around the Earth.
She started off on her path to the 'Milky Way' on November 19, 1997 as part of the six-astronaut crew that flew the Space Shuttle Columbia. She was the first Indian-born woman and the second Indian person to fly in space. On her first mission, she traveled over 10.4 million miles in 252 orbits of the earth, logging more than 372 hours in space. After that she was assigned to technical positions in the astronaut office to work on the space station, her performance in which was recognized with a special award from her peers.
In 2000 she was selected for her second flight as part of the crew of STS-107. This mission was repeatedly delayed due to scheduling conflicts and technical problems, finally she returned to space aboard Columbia on the ill-fated STS-107 mission. Her responsibilities included the microgravity experiments, for which the crew conducted nearly 80 experiments studying earth and space science, advanced technology development, and astronaut health and safety.
Kalpana Chawla died in the Space Shuttle Columbia disaster which occurred on February 1, 2003, when the Space Shuttle disintegrated over Texas during re-entry into the Earth's atmosphere, with the loss of all seven crew members, shortly before it was scheduled to conclude its 28th mission.
Where in the milky way galaxy is castor star found?
Present estimates of the dimensions of the Milky Way galaxy place its diameter at roughly 100,000 light years.
The star "Castor" in the constellation of Gemini is about 50 light years distant from our solar system,
or roughly 0.05 percent of the distance across the galaxy.
Castor is closer to us than your average next-door neighbor.
What is significant about the Milky Way galaxy?
For several decades, astronomers believed that the Milky Way galaxy was a spiral galaxy similar to M31 in Andromeda. But recent observations indicate that the Milky Way may actually be a "barred spiral" galaxy.
In either event, the Sun and our solar system are about 2/3 of the way out on one of the spiral arms, a very long way from the center of the Milky Way. Which is probably just as well, as recent research indicates that many galaxies including ours may have supermassive black holes at the center. So anywhere near the center of the galaxy would probably be a very nasty place to be!
Where can young metal-rich stars be found in the milky way?
The so-called "Population I" stars are found in the galactic suburbs, which is where we live. Population II stars are concentrated toward the galactic bulge.
What is the Milky Way bar's slogan?
Many years ago the slogan in the UK was "The sweet you can eat between meals without ruining your appetite."
This may have changed and may be different elsewhere.
Why is your galaxy called the milk way?
The Greek word Galaxy is "milk". The name Milky Way Galaxy is derived from the way intra-galaxy dust and clouds appear as they stream across the night sky.
We can not take a photo of the Milky Way as if we were at some distance from it. However we do know that the Milky Way is a Bard Spiral Galaxy with, we believe, 4 distinct spiral arms. This information enables artists to depict what the Milky Way would look like form a distance but these depictions are not photographs.
Some good photographs of how the Milky Way looks from Earth are linked to below.
Which of the following types of galaxy is the Milky Way an example an example of?
Please don't write "the following" if you don't provide a list - it just doesn't make sense.The Milky Way is a spiral galaxy.
How far is our solar system from the Milky Way?
It is not any distance from it. Our solar system is in the Milky Way.
The inner parts of the galaxy rotate faster than the outer parts. No structure that big could maintain itself with that type of forces - it would simply break apart.
