Welcome To The Heart Of The Milky Way…

When it comes to my job, I see a lot of astrophotography. I’ve contemplated innumerable nebulae, viewed myriad galaxies and dreamed over abounding star clusters. Each photo is a work of art in its own right – where the palette is a computer program and the canvas is a screen. These creations are stunning, showing us the true nature of what lay just beyond the visible perception of human sight. However, there are very few that when printed seem to have life of their own. This snapshot in time is one of them…

When this image was originally revealed on November 10, 2009, it was meant to commemorate Galileo’s 400th anniversary of turning a telescope towards the heavens. At the time, 150 prints were released to libraries, schools, planetariums, nature centers and observatories across the country. These massive six feet by three feet prints are a composite of a near-infrared view from the Hubble Space Telescope, an infrared view from the Spitzer Space Telescope and an X-ray view from the Chandra X-ray Observatory into one multi-wavelength picture.

What no one could prepare you for is the emotional impact such an image could have on you… If only you let it.

In this revelation of the heart of the Milky Way you’ll witness star birth – and death. You’ll travel along the effects of a supermassive black hole nearly four million times more massive than our Sun. You’ll walk into a complex web weaved from glowing gas clouds, dripping with globules, filaments and dark, dusty cocoons where neophyte stars await their turn to emerge. You’ll be swept away on the glowing blue stellar winds of X-ray light and dropped into the well of infra-red. You’ll feel yourself uplifted… Pulled into the “pillars of creation”. You’ll fly along hundreds of thousands of stars that could never be seen in visible light.

In short, you can’t walk away untouched.

Each telescope's contribution is presented in a different color: Yellow represents the near-infrared observations of Hubble. They outline the energetic regions where stars are being born as well as reveal hundreds of thousands of stars. Red represents the infrared observations of Spitzer. The radiation and winds from stars create glowing dust clouds that exhibit complex structures from compact, spherical globules to long, stringy filaments. Blue and violet represent the X-ray observations of Chandra. X-rays are emitted by gas heated to millions of degrees by stellar explosions and by outflows from the supermassive black hole in the galaxy's center. The bright blue blob on the left side is emission from a double star system containing either a neutron star or a black hole. Credit: NASA, ESA, SSC, CXC, and STScI

To see the full size image here on your screen is one thing, to see it accompanied by the individuals that make up the three by four feet composite is nice… But it’s the difference between looking up an image of the Mona Lisa and looking at the Mona Lisa as it hangs in the art gallery. I strongly urge you to investigate these NASA’s Great Observatories – Galactic Center Image Locations and take the time to visit in person.

You won’t regret the experience.

My many thanks go to Rich Ruggles of Astronomy 1 On 1 for opening my eyes to all the joy, wonder and mystery all over again.

    There have been _so_ many nights where I’ve found myself all alone viewing the glories above from my mountainside perch, and wondered… “Where is everybody? Don’t they know how incredibly beautiful and wondrous the night sky can be?” Off in the distance I quite frequently hear coyotes calling accompanied by the howls and yells of drunken revelers in their mountain retreats (Weekenders) and I remember – There are some who go to bars, and then there are some who look at the stars!

    Thanks for this image Tammy.. and thanks for being one of us who look up at the stars!

    Goodbye summer sky… here comes Mr. Winter!

    Why is the center of the galaxy not in the center of the image? Just asking.

    Below the center right orange ball of gas/stars with the unicorn horn looking thing coming off it, there is a very bright perfeclty round thing. Its bigger and brighter than many of the clusters I see in the whole photo. Very asymmetric cluster?

    I’m touched.

    “I tawt I taw a proppy plyd – I did! I did!” (Actually, a dumbbell so likely a planetary nebula, but who counts pre- or post stages?)
