Scientists don't know. We have only discovered a few hundred of the probable billions of planetary systems in this galaxy.

When did the milky way galaxy form?
well in my search i came up on these 2 explainations:1) The Milky Way is a translation of the Latin Via Lactea, which in turn is derived from Greek (Galaxias) sometimes referred to simply as "the Galaxy".2) "The Ganga of the sky", is the ancient Hindu name for the galaxy as viewed from the Earth. this was called "Akash Ganga ", it is the Hindi name for Milky way.hope that helps....
What other types of galaxies are there besides the milky way?
The answer is YES. There are an estimated 200 billion galaxies in the known Universe. Most of these galaxies are relatively similar to our own, some bigger, some smaller, some differently shaped. Most galaxies hold 50-200 billion stars, and average about 50,000 - 100,000 light years across. Light travels at 180,000 miles PER SECOND, so if it only takes 2 seconds to get to the moon, 30 seconds to Mars, but 100,000 light years to cross our own galaxy, imagine the size! Mind boggling!
When was the spiral galaxy discovered?
It wasn't until telescopes that people realized that the band of light reaching across the sky, called the Milky Way since ancient times, was actually made of an immense number of stars. Astronomers still did not really understand what they were seeing until the 20th century, however.Until the 1920s, astronomers thought that what we now know to be our Milky Way Galaxy to be the entire universe, and that our whole universe was a few thousand light years across. Other "spiral nebulae" had been observed, but they were thought to be new star systems forming nearby. After Hubble (the astronomer, not the telescope named for him) observed Cepheid variable stars in the Great Nebula in Andromeda, he realized that the Andromeda "Nebula" was immensley distant, and ennormous in size, and, by extension, the other "spiral nebulae" were also huge and incomprehensibly distant. He called them "island universes", and realized that we were also in one, and that the 'Milky Way' band of stars across the sky was our galaxy's disk, seen from inside. So, even though people have been calling the band of light across the sky the Milky Way for thousands of years, it wasn't until the 1920's that we understood what it was--our galaxy!We can see only a small part of our galaxy in visible light. Since the 1960s, radio astronomers have mapped out the structure of the entire galaxy, and shown it to be a large spiral galaxy of about 100 billion stars; we are in one of the spiral arms about 8 kiloparsecs (25,000 light years) from the center of our galaxy, more or less halfway from the center to the edge.I think Gallileo came across the milky way in the 1600's. The cloudy band we now call the Milky Way has been known since ancient times (it's referenced in various cultural mythologies, for example). However, it was only in the past few centuries that it was properly identified as a galaxy, specifically our own.== == The Milky Way's true age hasn't been discovered. The only knowledge we have is of a meteorite which dates 4.7 billion years ago. And yes, Galileo discovered the odd colors of the Milky Way in the 1600's. If we could escape our galaxy, scientists believe it would look like M-31(The Great Galaxy of Andromeda)I would hesitate to talk about a "discovery" of something that is in plain sight - that people have been seeing for ... well, for as long as there have been people. Like the Sun, or the Moon, or trees, or animals - or the Milky Way.
Who made up aliens and how did they get made up?
No one made up aliens. They either exist or they don't. Dr. Frank Drake of the SETI Institute designed a formula that can be used to predict the potential for the existence of life elsewhere (anywhere other than Earth) in the universe. Essentially, the Drake Equation is a probability predictor, and presents the high probability that life does exist somewhere. The equation is: N = R* • fp • ne • fl • fi • fc • L What that means is: N = Is the number of civilizations in The Milky Way Galaxy whose electromagnetic emissions are detectable. R* =Is the rate of formation of stars suitable for the development of intelligent life. fp = Is the fraction of those stars with planetary systems. ne = Is the number of planets, per solar system, with an environment suitable for life. fl = Is the fraction of suitable planets on which life actually appears. fi = Is the fraction of life bearing planets on which intelligent life emerges. fc = Is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space. L = Is the length of time such civilizations release detectable signals into space. The idea that there could be other life in the universe was a groundbreaking concept in 1961 when Drake first presented his idea. At that time, we did not know of any other planetary bodies around other stars. As of the writing of this answer (October 2013) 990 planetary bodies have been discovered in 754 planetary systems. The Kepler mission has detected thousands of potential candidate stars with potential planets orbiting them, and 252 potentially habitable planets. It has been estimated that there may be 17 billion Earth-sized planets in the Milkyway Galaxy (our galaxy) alone. Considering the numbers and what we have discovered so far, it would the the height of arrogance to presume we are alone in the universe. 990 planets in 754 planetary systems
The scientist who proved the existence of galaxies other than the Milky Way was who?
Mister Edwin Hubble did just that, before the 1920's, many astronomers thought that our galaxy included everyobject in space, in 1924 Edwin Hubble proved that other galaxies existed beyond the milky way
What will the James Webb telescope detect?
Webb will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. Webb will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. Webb's instruments will be designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range.
Who first studied milky way galaxy?
The Ancient Greeks first studied the milky way but they thought that the stars were holes in a dome surrounding the earth
Is the Milky Way Galaxy the smallest galaxy in the universe?
All of them are. Generally elliptical galaxies are the oldest.
Other galaxies were first believed to be?
Nebulae or star clusters within the Milky Way Galaxy.
What is the first planet called in the Milky Way?
Any planet you fancy. There is no "starting" point in our Galaxy.
Who was first observed the Milky Way galaxy?
The Milky Way can be seen with the naked eye, so we can assume that people have been observing it before written history.
When did they discover the milky way galaxy?
From a site far away from a city, you can see the milky way easily. It was probably first seen hundreds of millions of years ago.
Why don't you fly UP out of the galaxy instead of out past the other planets wouldn't that be the fastest way out of the galaxy?
You first have to get past the planets of our solar system (which is IN our galaxy) in order to then make movements to get out of the entire Milky Way galaxy.
What are facts about the milky way galaxy?
It's a barred spiral. There's a supermassive black hole at its heart. It's a cannibal. You can only see 0.000003% percent of it 90% of it is invisible. It has the same proportion as a stack of four DVDs ...sorry that's all i could find who ever wrote this is stupid and don't got no brain get a life!!!!!!!!!
What was the name of the first galaxy ever made?
a telescopeIn 1925, Edwin Hubble discover cepheid variable(s) in what we now call the Andromeda Galaxy. From those he could tell that the group of stars was too far away to be part of the Milky Way. It was the first proof that other galaxies exist.
Is the Andromeda Nebula Galaxy closest to The Milky Way Galaxy Or is there another that is even closer?
The closest galaxies to the Milky Way are(in order of increasing distance):Sagittarius Dwarf GalaxyCanis Major Dwarf GalaxyThe Large Magellanic CloudThe Small Magellanic CloudThe Andromeda GalaxyThe Triangulum GalaxyNote: The first four galaxies are dwarfs, which are significantly smaller than the Milky Way. The two Magellanic Clouds are in orbit around our Milky Way. The Andromeda Galaxy is around 15% heavier than the Milky Way(I'm not very sure about this, but you can check in Wikipedia). The Triangulum Galaxy is around 20% lighter than the Milky Way(Not very sure about this also).
Is Milky Way first or the universe?
The Milky Way is our galaxy, the galaxy that contains our solar system and almost all of the objects we observe in our sky. At the time of the theorized 'big bang', the very beginning of our universe, there were no galaxies and no stars in existence. That all came much later.
