Detailed observations of the galaxies around us indicate that there is superposed on the Hubble flow a large-scale streaming motion of about 600 km/s in the general direction of the constellation Centaurus.

Strange how the image almost looks like a Yin Yang.

It's kinda like a Doppler effect...I think...It just blows my mind how many different ways we're moving--spinning on earth's axis..in orbit around the Sun...in orbit around the center of the Galaxy...and Glaxies in orbit around...Yikes....dizzy... and at such speeds...I get dizzy thinkin' about it...

and it can all be measured--up to a point!

Careful papa. This stuff can really suck you in. Next you'll be buying Stephen and Lucy Hawkin's book - George's Secret Key to the Universe, under the pretense that it is for one of the grandkids or neighbour's kids birthday. A good read for adults and kids.
Amazing stuff.

The Hawkins people, huh? Sounds like fun time at reading to the grandkids--if I ever get to see 'm again! I just like to get my head out of the every day banality and human greed, the soul-killing stuff like plastic oceans and banking rip offs, betrayals by Presidents, neh?

<B> Explanation: </B>
Our <A href="http://antwrp.gsfc.nasa.gov/apod/ap070325.html">Earth</A> is not at rest.
The Earth moves around the <A href="http://antwrp.gsfc.nasa.gov/apod/ap070624.html">Sun</A>.
The Sun orbits the center of the
<A href="http://antwrp.gsfc.nasa.gov/apod/ap071020.html">Milky Way Galaxy</A>.
The Milky Way Galaxy orbits in the
<A href="http://www.seds.org/messier/more/local.html">Local Group of Galaxies</A>.
The Local Group falls toward the
<A href="http://antwrp.gsfc.nasa.gov/apod/ap050213.html">Virgo Cluster of Galaxies</A>.
But these speeds are less than the speed that
all of these <A href="http://antwrp.gsfc.nasa.gov/apod/ap071211.html">objects together</A>
move relative to the
<A href="http://www.astro.ubc.ca/people/scott/faq_basic.html">cosmic microwave background radiation</A> (CMBR).
In the
<A href="http://lambda.gsfc.nasa.gov/product/cobe/dmr_image.cfm">above all-sky map</A> from the
<A href="http://en.wikipedia.org/wiki/COBE">COBE satellite</A>,
radiation in the Earth's direction of motion appears
<A href="http://imagine.gsfc.nasa.gov/docs/dictionary.html#blueshift">blueshifted</A> and hence hotter, while
<A href="http://blogs.discovermagazine.com/cosmicvariance/2008/03/05/wmap-5-year-results-released/">radiation</A> on the opposite side of the sky is
<A href="http://en.wikipedia.org/wiki/Redshift">redshifted</A> and colder.
The <A href="http://map.gsfc.nasa.gov/">map</A> indicates that the
<A href="http://en.wikipedia.org/wiki/Local_group">Local Group</A> moves at about 600 kilometers per second relative to this
<A href="http://www.youtube.com/watch?v=S4QWnBJvVq4">primordial radiation</A>.
This <A href="http://www.youtube.com/watch?v=CVaNBrYLvFg">high speed</A> was initially unexpected and its magnitude is still unexplained.
<A href="http://en.wikipedia.org/wiki/Cosmic_microwave_background">Why are we moving so fast</A>?
<A href="http://antwrp.gsfc.nasa.gov/apod/ap000104.html">What is out there?</A>
