The Entire WISE Sky

I love maps like this where astronomers take the entire night sky and project it so we can view it in two dimensions. Zoom into and explore the entire sky infrared mosaic from the Wide-field Infrared Survey Explorer (WISE). Some things to note in the image. The bright swath across the center is the Milky Way Galaxy; our home galaxy. The view is toward the center of the galaxy with the spiral arms stretching to the edges. Some artifacts were left in such as bright red spots off the plane of the galaxy. These are Saturn, Jupiter and Mars.

[UPDATED: The WISE website has a annotated guide to the objects found within the entire WISE Sky image. Click on the image for a closer view.]

What is the blue orb shape in the middle?

What are the bright spots that are mid-bottom of shot towards the right and the greenish-yellowish one right above the middle?

This is awesome! People are like caterpillars in a garden; when a caterpillar only knows about life in the garden; the mountains, the oceans, the valleys and meadows beyond the garden exist, but until the caterpillar goes through the Chrysalis stage and emerges from its cocoon with wings allowing it to fly beyond the garden; the caterpillar will never actually know those places exist. Why? The caterpillar is supposed to focus on life in the garden and eat the best leaves and “be” a caterpillar. When the caterpillar is ready to become a butterfly; it will; but only when it has done all a caterpillar can do in a garden.

It is great that we look beyond our planet to search for other life forms; but while all sorts of time, money, technology, brain power, etc… is focused on the Universe beyond our tiny garden planet; our tiny garden planet, our atmospheric life permitting, miraculous Mother Earth…is being raped, polluted and stripped of all its natural resources for the short term benefit of the human population.

Ignorance must be bliss or we need to redefine “intelligent”…people, open your eyes and “see”, you have them for a reason; listen with your ears; you can hear for a reason; use your minds, you have the ability to think, for a reason. You have the power to transform the world; look at what you are doing to it…the whole world is in your hands…literally at your fingertips with the internet.

With all that we know and all we have learned; why aren’t we doing a better job at being guardians of this world? Are we devils or angels? Hmmm…they say that the devil is the master of fire; well, humans have used fire to separate themselves from the natural world; for survival…to be the fittest. We have used heat to transform the natural resources of the planet into man-made, concrete, pollution generating metropolises.
LOL. We are what we fear the most and don’t even realize it. Hah. I guess the jokes on? Us?

The Milky Way, our home galaxy, runs through the center of the image. The image is centered on the center of the Milky Way. Our galaxy is a barred spiral galaxy (similar to this image of NGC 1672 – http://hubblesite.org/gallery/album/pr2007015a/) with a large central bulge of stars that tapers out to the tips of the spiral arms. Some galaxies, like this image of ESO 243-49 (http://hubblesite.org/gallery/album/galaxy/spiral/pr2012011b/) show us this structure really well. Earth is about two-thirds of the distance from the center to the edge of the galaxy (http://en.wikipedia.org/wiki/File:236084main_MilkyWay-full-annotated.jpg), so we see a great many stars toward the center.

About the objects below the disk of the galaxy. These are the Small and Large Magellanic Clouds. Both are nearby dwarf galaxies about 170,000 light-years from Earth. Both can be seen in the skies of the southern hemisphere as cloud-like objects in the sky. They are not visible from North America. The Large Magellanic Cloud is home to one of the largest star-producing nebulae that we know about.

Welcome

The ancient peoples saw pictures in the sky. From those patterns in the heavens, ancient storytellers created legends about heroes, maidens, dragons, bears, centaurs, dogs and mythical creatures...
