Distance between earth and edge of milky way?
The distance of the earth to the edge of the Milky way is 1000 light years
What discovery made Edwin hubble believe there there is more universe than the milky way?
Hubble did not discover that there were other galaxies; that had been discovered earlier. But Hubble was the first to demonstrate that the more distant another galaxy is, the faster it is moving away from us.
Edit: I'm not sure that's right. Hubble was surely the first to prove that a
"spiral nebula" was too far away to be in the Milky Way. That nebula
is what we now call the "Andromeda galaxy".
I know that Slipher and others did important earlier work on red shifts,
but I'm pretty sure Hubble did discover that other galaxies existed.
You can do whatever is comfortable but generally the girl holds the boys arm given the sense he is leading her and protecting her.
Where are the Population One and Population Two stars located in the Milky Way Galaxy?
Population I stars (metal-rich stars) are common in the Milky Way's spiral arms; Population II stars are more common in the galactic halo.For more details, you may want to read the Wikipedia article on "Metallicity". Note that in astronomy, "metal" is an informal name for elements other than hydrogen and helium. This usage is quite different from the usage in chemistry.
Well considering stars die and are born all the time, the number would change all the time.
However, at the current estimate of 300 billion stars. At one a second a star, it would take about 9,500 years.
How cold is the coldest place in the milky way?
The Milky Way is not a uniform object; different parts have different temperatures. In outer space, the temperature can go down to a few Kelvin (that is, almost absolute zero); in the center of some stars, the temperature can be a hundred million Kelvin, or even more. (Note: At temperatures of millions of degrees, Kelvin is the same as as Celsius, for practical purposes.)
How was the sleeping giant formed?
the sleepig giant also known as the nounou mountain was formed when a giant ate too much and layed down to rest and has not yet woken
Where is Sirius in the milky way galaxy?
Find Orion's Belt, and follow its line of stars down to the left and you will find Sirius. It is unmistakeable. It is easily visible in the winter but not summer.
Altenatively, look for the brightest thing other than the moon, and you've found it.
Galaxies closest to the milky way?
- The Large and Small Magellanic Clouds, which are 2 small galaxies orbiting the Milky Way.
- The Andromeda Galaxy, which is slightly larger than the Milky Way.
- The Triangulum Galaxy, which is slightly smaller than the Milky Way.
How far does the solar system move in a year?
I hope you are aware that movement must be expressed in relation to some reference point. If you mean the Solar System's orbital velocity around our Milky Way, that happens at a speed of about 220 km/second. You can base your calculations on that.
A quasar will only exist in a really big galaxy... our galaxy, the milky way, isn't in any danger, because although we have a black hole at the centre of our galaxy; there is not enough matter to create the conditions for a quasar.
Many years ago, when modern Astronomy was still in its infancy, astronomers looked at all the lights in the sky and tried to figure out what they were. Some were stars, bright points of light, and some were smudgy, smeared objects; almost cloudy-looking. Those got the label "nebula", from the Latin word for "cloud". But it was difficult to determine how far away the objects were; the relative brightness was one of the few clues.
Later on, Edwin Hubble realized that the universe is expanding, and that most of the other galaxies were receding from us. By measuring the red-shift of the stars or galaxies, astronomers were able to determine how fast the objects were going, and because of the nature of the expansion, had a new way of determining distances.
There was one BIG problem. There were stars that appeared to be point-sources, so they weren't galaxies or nebulae, but were receding too quickly - and therefore too far away - for any star to be visible. There was just NO WAY for a star to be bright enough to be visible from that far away. From their distance and their brightness, they would need to pack the brightness of a galaxy into the size of a solar system, which was clearly beyond our (then) comprehension.
Astronomers named them "Quasi-Stellar Objects", and because most people are too lazy to use three words when one will do, shortened it to "quasar".
It took decades for some agreement to be reached on what the objects are that are so bright and yet so distant, but the current thinking is that a quasar is the accretion disk of gas and matter heated to incandescence by the gravity of a supermassive black hole in the center of what may have once been an "ordinary" galaxy.
There are about 1500 volcanoes on land that are known to have have been active .
The spiral shape of the milky way galaxy cannot be seen from earth because?
we are located within one of its spiral arms.
What are the other galaxies accept Milky Way?
The observable Universe has at least a hundred billion galaxies. The galaxies closest to us are part of the so-called "Local Group" (that is, the group that includes our galaxy); this Local Group includes our own galaxy (i.e., the Milky Way), the Andromeda Galaxy, the Triangulum Galaxy, and about 50 dwarf galaxies such as the Large Magellanic Cloud and the Small Magellanic Cloud. Then, of course, there are hundreds or thousands of galaxies "near-by" as distances between galaxies go, but outside of our Local Group.
What is the 6th biggest planet in the milky way?
We have no idea and never will.
The 6th biggest planet in the Solar System is Venus.
How thick is the bulge of the milky way?
Recent evidence suggests that the Milky Way is a barred galaxy, and does not have a bulge in the classical sense. One estimate for the thickness of the central part of the Galaxy is ca. 16.000 ly. But if I were you, I would not put too much stock in this answer: astronomers are still learning new things about our galaxy every day, and the figure may well double - or halve - come next month.
What Is thin gas and clusters of stars surrounds the disk of the milky way galaxy?
what is the thin gas and clusters of stars surrounds the disk of the Milky Way Galaxy.
What is the distance that the Milky Way galaxy travels through space in one year?
The stellar disk of the Milky Way Galaxy is approximately 100,000 light-years (9×1017 km) (6×1017 mi) in diameter, and is considered to be, on average, about 1,000 light-years (9×1015 km) thick. It is estimated to contain at least 200 billion stars and possibly up to 400 billion.
The rotation of Pluto is inclined approximately 119.5 degrees to it plane of orbit
What is Andromeda doing relative to the Milky Way?
Andromeda is heading straight for us here in the Milky Way, and the two galaxies are going to collide. Don't lose any sleep over this; it isn't going to happen for roughly four billion years. By then the earth will very likely no longer be inhabited, and who knows where are descendants will be, if there will be any at all?
