The section of the night sky where you view the milky way galaxy edge on. There are so many stars in this part of the night sky that it look like a path of spilled milk - therefore it is called the milky way., The Milky Way is the galaxy in which the solar system is located. It is a barred spiral galaxy that is part of the local group of galaxies. It is one of billions of galaxies in the observable universe.
The Milky Way galaxy contains?
The Milky Way galaxy contains billions of stars, including our sun, as well as various celestial objects such as planets, asteroids, and comets. It spans a diameter of about 100,000 light-years and is estimated to have between 100 to 400 billion stars.
What is the distance across the Milky Way?
The Milky Way is approximately 100,000 light-years in diameter. This means that if you could travel at the speed of light, it would take you 100,000 years to cross from one side of the galaxy to the other.
Stars generate light through nuclear fusion in their cores. This process involves converting hydrogen into helium, which releases energy in the form of light and heat. The intense pressure and temperature within a star's core allows this fusion process to occur.
Biggest star in the milky way?
The biggest star in the Milky Way is currently believed to be UY Scuti, a red supergiant star located in the constellation Scutum. It is estimated to be over 1,700 times larger than the Sun in terms of volume.
How many stars are there in the galaxy?
A typical galaxy may have anywhere between a few million (106) stars, and over a trillion (1012) stars. Our own Milky Way is estimated to have between 200 and 400 billion (2x1011-4x1011) stars.
The aphelionis the point in the orbit of a planet or comet where it is farthest from the Sun. The Earth reaches its aphelion when the Northern Hemisphere is experiencing summer. The point in orbit where a planet or comet is nearest to the sun is called the perihelion. The word aphelionderives from the Greekwords, apomeaning away, off, apart and Helios(the Greek god of the sun). Earth's aphelion usually occurs sometime around July 4.
What is the distance to the center of the milky way?
The distance from Earth to the center of the Milky Way is approximately 25,000 light-years.
What would happen if the Milky Way was a quasar?
If the Milky Way were a quasar, it would be incredibly bright and emit vast amounts of energy due to the supermassive black hole at its center consuming huge amounts of matter. The high energy output would impact the surrounding galaxies and alter the dynamics of the entire universe.
What would happen if a 200000 light years wide spiral galaxy collided with the Milky Way?
Likely the two galaxies would become one. Though there is some speculation in all likelyhood some stars would be lost in the process.
Incedentally in 3-5 billion years the galaxy Andromeda may collide with the milky way and it is about that size (a little smaller). In all likelyhood whan that happens our star will probably be lost fly out into the universe or into another dwarf galaxy.
Whatever happens the two galaxies would take a different course through the universe depending on how much mass the colliding galaxy has. (if it is Andromeda it is likely that we will continue on the course that we are on now)
We can calculate the mass of the Milky Way by analyzing our solar system's orbit around the center of the Milky Way. The only problem is, that orbit takes about 220 million years to complete, and human beings have been observing it for less than 200. So our calculations could be - probably are! - way off.
Is the solar system about halfway between the center of the Milky Way galaxy and its outer edge?
The solar system is the Milky Way galaxy, Earth, and all other planets and galaxies are the solar system.
How many planet have water in the Milky Way?
There is believed to be water, both naturally forming, and through man's intervention.
On November 13, 2009, scientists from NASA's Lunar Crater Observation and Sensing Satellite said unequivocally there is water on the moon and plenty of it.
In October 2009 a satellite slammed into a crater on the moon and about 24 gallons of water filled the hole from the impact.
See related link for a New York Times article.
It hasn't yet been definitively established that there is no water ice anywhere on the moon. The 'Lunar Prospector' spacecraft indicated that water ice might be present at both the north and south lunar poles, in agreement with 'Clementine' results for the south pole. It isn't known how much water could actually be found.
Although the moon does not have pockets of water like earth, water deposits have been found in soil deposits that where taken from the moon in the first Apollo missions. These deposits looked like orange dirt and it was not discovered until recently that these orange particle contain water.
A report was released in September 2009, indicating that an Indian lunar exploration team had indeed found "large quantities of water" on the moon. Furthermore, data collected from the Chandrayaan-1 spacecraft also pointed to the strong possibility that water was still being formed on the moon.
See the related link for the article.
Is the Milky Way an asteroid belt?
No, the Milky Way is not an asteroid belt. It is a large barred spiral galaxy that contains our solar system along with billions of stars, gas, and dust. An asteroid belt is a region in a solar system where many asteroids are found orbiting the Sun.
How many au is the sun from the center of the Milky Way Galaxy?
An AU is the wrong measurement, that's like asking how far it is from London to New York - in millimeters.
An AU is merely the average distance from the Sun to the Earth, some 50 million km. The Milky way is about 100,000 Light years in diameter - a light year is about 10 trillion kilometers (10^16km = 10,000,000,000,000,000km).
Since we are on the outer edge of one of the spirals, make that 50,000 light years from the Sun to the center of the Milky Way. So if my math is right,
(50,000 * 10^16 )/ (50 * 10^6)
= (5 * 10^20) / (5 * 10^7)
= 10^13 AU
How many years until the Andromeda and Milky Way galaxies collide?
There are 2 much smaller irregular galaxies that orbit our galaxy called the Magellanic Clouds. These are abbreviated LMC and SMC (large and small Magellianic Cloud). These will one day gradually collide with The Milky Way but it is a long time until that happens; no need to worry. There is also the Andromeda Galaxy which is on a collision course with us.
Will Earth ever fall into the black hole at the center of the Milky Way Galaxy?
No, Earth will not fall into the black hole at the center of the Milky Way Galaxy. The black hole is located about 26,000 light-years away from Earth, and our solar system is orbiting it at a safe distance. The gravitational pull from the black hole is not strong enough to pull Earth into it.
What does the Milky Way simply caramel taste like?
Milky Way Simply Caramel has a rich and creamy caramel flavor enveloped in smooth milk chocolate, creating a sweet and indulgent taste experience.
Is the milky way galaxy located 2.2 million light years from the sun?
No. Reach up and pinch your nose; that's part of the Milky Way you are pinching! We - each and every one of us here on Planet Earth - are as much a part of the Milky Way as one of your hairs is part of YOU. We're part of the Earth; the Earth is part of our solar system. This solar system, and every individual star you can see in the sky, are part of the Milky Way.
Diameter of the milky way in kilometers?
Ok you asked for it
Our Sun is 1,400 light years from the galactic center of the Milky-way now given that the sun and all of us here are on a trip around the Milky way for the next 220 million years it takes to do one cycle of the Milky-way and also the Milky way is on a trip which takes 50 million years to rotate, thus this answer is variable ( not, I am sure, that this matters in our daily lives)
This equates to 300,000 (the speed at which light travels in near kms) x 60 ( to make one minute) x60 ( to make the hour) x 24 ( to make the day) x 1400 (the distance of the sun to the galactic center) x 364.25 (to turn days into years) =132,179,040,000,000,000,000,000 kms from the galactic center or about 130 thousand billion billion kilometers
or 130 billion trillion kilometers
or 130 thousand million million million kilometers
or better still 1,400 light years
How many stars in the milky way galaxy have earth like planets?
It is estimated that there are billions of stars in the Milky Way galaxy that could potentially have Earth-like planets within their habitable zones. The exact number is difficult to determine with certainty due to the vastness of our galaxy and the limitations of current technology.
Why have no pictures been taken outside of the milky way galaxy?
We are inside the Milky Way galaxy, and so it is difficult to tell exactly what it looks like from the outside - because we aren't "outside."
Think of it like this: If you are inside your house and never went outside, you could still look out the windows and see other houses. But you wouldn't be able to SEE your house. You could figure it out, by drawing a diagram - but it isn't the same thing as seeing it from the outside.
From Earth, we see thousands upon thousands of stars. With big telescopes, we can also see other things between the stars, and some of those things are other galaxies.
---
Some galaxies are hard to see because dense groupings of stars and nebulae in the Milky Way are in the way. But given that, we can see a dozen or so "satellite" galaxies of the Milky Way, and the next closest galaxies are those in the Andromeda group, some 2 million light-years away. This means that the light we see left Andromeda more than two million years ago. We are seeing them as they were that long ago. However, galaxies persist for billions of years, so they are likely very little changed from what they looked like then.
The very fastest human-made spacecraft ever aren't out of this solar system yet, and they were launched in the 70s.
"Billions of years" is, if anything, an understatement.
What is the closest spiral galaxy to the Milky Way Galaxy?
The closest galaxy to our galaxy the Sagittarius galaxy but its Dwarf Galaxy, Andromeda is the Complete Galaxy and yet classified as the Galaxy which is closest to our galaxy. Facts : There are 12 Dwarf galaxies and 1 complete galaxy within the distance of 500,000 light years. Andromeda Galaxy is moving towards our galaxy at the speed 300,000 Kilometers per hour, but its so far that i would take millions of year to have a clash.
