Before the telescope was invented in 1608, our picture of the universe consisted of six planets, our moon, the sun and any stars we could see in the Milky Way galaxy. But as our light-gathering capabilities have grown, so too have the boundaries of the visible universe. Our interactive map shows how the known universe has grown from 1950 to 2011.
In the late 1700s, William Herschel, an English astronomer using a telescope with an 18.7-inch aperture, made the first systematic surveys of the skies, revealing more than 2,000 distant galaxies, nebulae and other objects invisible to the naked eye. Since then, increasingly powerful optical and radio telescopes have greatly expanded our store of knowledge.
In 1948, astronomers erected the 200-inch Hale Telescope at Palomar Observatory in California, and now, large-scale projects such as the Sloan Digital Sky Survey and NASA's Kepler mission use sensitive digital imaging and computational power to collect and analyze hundreds of terabytes of data on millions of galaxies billions of light-years from Earth. With each additional bit of data, the universe itself grows larger.
lol on earth it says discovered before 1950
Diggin' the Copernican view of the known universe :P
Um, guys...the map link just leads to a 404 page.
Prior to our cosmos forming and prior to the big bang, that was all there was, just a "404" page. ;)
Don't listen to RicardoMay, a total scam and you will be robbed. It happened to a moron friend of mine. Oh, and Popsci should really screen these spammers!!............and get the links to work.
The Earth is the center of our Universe in this map and GOD rules over us all!
Try again, I got there just fine.
Dear person who click on "Reported to site admins". Please do not be offended I mention GOD in my comment. I was really bringing to attention the design of the map. The EARTH is at the center which is an ancient belief system, including the belief in GOD.
It seems nobody notice the EARTH being at the center and are not asking why it is illustrated this way.
They could have easily put the Sun in the center.
I just wonder what the map maker was thinking. This scientist maybe even sneeking in some of his religous point of view, right under our noses.
Do a search on old sea maps and old world maps. You often find the person who created the map, also added much of their own personal belief system with symbols, icons and other things into the map, that had nothing to do with map itself.
So begs the question, did this map maker of this article put anything extra into this map from his belief system?
The Earth is the center of the map because that is where the observers are. This is obvious. We don't look at the universe from anywhere else.
Yeah but wouldn't it have been better to map out what we know from the perspective of the center of the galaxy? That way we could easily discern how much of the galaxy we know about and how much we have yet to explore. I don't know, maybe that's just my way of thinking about things.
I can see your view. This is a map from the view of humanity and the earth is center simply because it is the one thing we know the most about. Poor Galileo, I suppose despite scientific facts human self wins on this map. You know the Christians of Galileo time period would be so happy. Ta'da!
Oh while you say it is obvious should be in the center; that is really your opinion. Do we know for fact what motivated the map maker in this picture to put earth as center, not unless we ask him?
