firstly a very very good question!! answer is - Because quite simply, we are within it. If we were out side of our Galaxy, then we could "see" the spiral shape. But don't expect to see it for a longgggg time. It's over 25,000 light years to the edge and a lot further if you want to see it, in it's entirety. All images are artists impressions.
Rohan is right, because we are within it, we cannot detect the spiral shape of the galaxy. It is just like why we cannot detect the movement of the earth(because we are on it).
but 1 way is that pratu reminded me is google earth software
dude...because the size our reach or vision is only upto sun and even we are not ble to recognize nine planets perfectly with naked eyes... I mean to say .... our limit is very small and U CAN NEVER OUT OF MILKYWAY TO VIEW THE GALAXY bcz there are thousands of other STARS, like sun,,, planets. the shape of our galaxy what we conclude...(SPIRAL) is just a mathematical calculation by estimating the explosions in universe.. WE CAN NOT GO OUTSIDE THIS GALAXY TO TAKE ITS PIC :-D
actually, we expect to have something we've made escape our solar system soon--Voyager I (and later Voyager II) hit the outermost edge of what we define as the solar system. We can measure the movement of the earth quite easily with the hundreds of satellites that collect information on a staggering scale. And, although Voyager II is travelling in the direction we believe to be the shortest way out of our Galaxy--the likelihood that it will reach out of it (and we will receive any data about it) within our lifetimes is rather slim. http://voyager.jpl.nasa.gov/news/new_region.html
its ok if it escape our solar system....isnt it interesting that there are thoysands of solar sustems in milky way
I'm working on a degree in Astrobiology with emphasis in extra-solar systems, so I for one--find it absolutely amazing, lol.
srinidhijha you have lots of spelling mistakes but there's a gravitational pull (remember kepler's 1st 2nd and 3rd law) i|dw:1333021698112:dw| we will escape only if sun gets destoyed
@Rohangrr I didnt take what he said to mean the earth will physically escape our system (since that will never happen).. but rather that "we" as humans will either escape or as I mentioned with Voyagers I, II have a fancy computer escape for us and tell us fun things :P
good question I'm 13 what about you
>.> Now I feel old, Thanks :) I'll just say this, I have 2 bachelors degrees, 1 masters and I'm working towards a PhD... so, much older than 13 :P
do u have a gmail id pls give me i will then take guidance from u
During interphase the DNA is not condensed into chromosomes because the cell is using the DNA to code for proteins. It is once the cell begins to divide that the DNA condenses into chromosomes.
sry 4 the mistakes but...i dont mean physical escape of earth (:-D) ...I referred in d case of VOYAGER. IT is impossible to go out of several solar systems.
