Astronomy Picture of the Day - CMB Dipole: Speeding Through the Universe

Explanation: Our Earth is not at rest. The Earth moves around the Sun. The Sun orbits the center of the Milky Way Galaxy. The Milky Way Galaxy orbits in the Local Group of Galaxies. The Local Group falls toward the Virgo Cluster of Galaxies. But these speeds are less than the speed that all of these objects together move relative to the cosmic microwave background radiation (CMBR). In the featured all-sky map from the COBE satellite in 1993, microwave light in the Earth's direction of motion appears blueshifted and hence hotter, while microwave light on the opposite side of the sky is redshifted and colder. The map indicates that the Local Group moves at about 600 kilometers per second relative to this primordial radiation. This high speed was initially unexpected and its magnitude is still unexplained. Why are we moving so fast? What is out there?

All that movement, No wonder I’m tired.

I’ve seen those Red areas next to Blue areas on weather maps. It’s not good. There’s potential for a cosmic tornedo.

Book One -— The Voyage
Prologue

In the constellation of Cygnus
There lurks a mysterious, invisible force
The Black Hole
Of Cygnus X-1

Six Stars of the Northern Cross
In mourning for their sister’s loss
In a final flash of glory
Nevermore to grace the night...

1

Invisible
To telescopic eye
Infinity
The star that would not die

All who dare
To cross her course
Are swallowed by
A fearsome force

Through the void
To be destroyed
Or is there something more?
Atomized -— at the core
Or through the Astral Door -—
To soar...

2

I set a course just east of Lyra
And northwest of Pegasus
Flew into the light of Deneb
Sailed across the Milky Way

On my ship, the ‘Rocinante’
Wheeling through the galaxies,
Headed for the heart of Cygnus
Headlong into mystery

The x-ray is her siren song
My ship cannot resist her long
Nearer to my deadly goal
Until the Black Hole -—
Gains control...

3

Spinning, whirling,
Still descending
Like a spiral sea,
Unending

Sound and fury
Drowns my heart
Every nerve
Is torn apart....
