The Heavens Declare God’s Glory

It is well for us to remember the origin of all things.  On the edge, before the beginning and before there was such a thing as time, God was there.  Then, “In the beginning God created the heavens….”  (Genesis 1:1)  And, “…the heavens and the earth were completed in all their vast array.” (Genesis 2:1)  And now, to this day in time: “The heavens declare the glory of God; the skies proclaim the work of his hands.”  (Psalm 19:1)  And we are privileged to learn more and more about God’s power and creative genius through the marvels of science which He has graciously allowed us to discover.  Praise be to The Creator.   (RMF)

Stars gather in “downtown” Milky Way

The Spitzer Space Telescope penetrates the shroud of dust around the heart of our galaxy with infrared light, giving us an unprecedented view.

The region around the center of our Milky Way Galaxy glows colorfully in this new version of an image taken by NASA’s Spitzer Space Telescope.

The data was previously released as part of a long, 120° view of the galactic plane. Now, data from the center of that picture are being presented at a different contrast to better highlight this jam-packed region. In visible-light pictures, it is all but impossible to see the heart of our galaxy, but infrared light penetrates the shroud of dust, giving us this unprecedented view.

In this Spitzer image, the myriad stars crowding the center of our galaxy creates the blue haze that brightens toward the center of the image. The green features are from carbon-rich dust molecules, called polycyclic aromatic hydrocarbons, which are illuminated by the surrounding starlight as they swirl around the galaxy’s core. The yellow-red patches are the thermal glow from warm dust. The polycyclic aromatic hydrocarbons and dust are associated with bustling hubs of young stars. These materials, mixed with gas, are required for making new stars.

The brightest white feature at the center of the image is the central star cluster in our galaxy. At a distance of 26,000 light-years from Earth, it is so distant that, to Spitzer’s view, most of the light from the thousands of individual stars is blurred into a single glowing blotch. Astronomers have determined that these stars are orbiting a massive black hole that lies at the center of the galaxy.

The region pictured here is immense, with a horizontal span of 2,400 light-years (5.3°) and a vertical span of 1,360 light-years (3°). Although most of the objects seen in this image are located near the galactic center, the features above and below the galactic plane tend to lie closer to Earth.

The image is a three-color composite, showing infrared observations from two of Spitzer’s instruments. Blue represents 3.6-micron light and green shows 8-micron light, both captured by Spitzer’s infrared array camera. Red is 24-micron light detected by Spitzer’s multiband imaging photometer. The data is a combination of observations from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) project and the Multiband Imaging Photometer for Spitzer Galactic survey (MIPSGAL).
