APOD: 2009 December 22 - Planetary Systems Now Forming in Orion



Explanation: How do planets form? To help find out, the Hubble Space Telescope was tasked to take a detailed look at one of the more interesting of all astronomical nebulae, the Great Nebula in Orion. The Orion nebula, visible with the unaided eye near the belt in the constellation of Orion, is an immense nearby starbirth region and probably the most famous of all astronomical nebulas. Insets to the above mosaic show numerous proplyds, many of which are stellar nurseries likely harboring planetary systems in formation. Some proplyds glow as close disks surrounding bright stars light up, while other proplyds contain disks further from their host star, contain cooler dust, and hence appear as dark silhouettes against brighter gas. Studying this dust, in particular, is giving insight for how planets are forming. Many proplyd images also show arcs that are shock waves - fronts where fast moving material encounters slow moving gas. The Orion Nebula lies about 1,500 light years distant and is located in the same spiral arm of our Galaxy as our Sun.

The Orion Nebula is a fascinating place. It will be interesting how many planetary systems in formation they discover.

I like how you can see in each of the little insets breaks of symmetry, where an otherwise spherical cloud of condensing gas is being uberfucked by winds in the nebula.

The last place I would want to be is in a swirling, chaotic debris cloud filled with massive objections colliding and heating up, as gravitational forces pull in every conceivable direction. :lol:

Eh, results may vary depending on where you stop :lol:

But in general, you'd be toast :yesway:

Good call, Ken...

I like how there's a peacock and an alien in the picture too!

peacock: just down and left from the center of the image

alien: far right of the image, looks like he's wearing a hoodie
