Re: New Discoveries *3* - ...MORE deep space, extraplanetary, etc.

*More treats from Astropix:

*Stunning.  And so many bright stars in the field.  Is 3000 light years away.

*How did I miss this image last year?  Sometimes I think the folks at Astropix shuffle images around afterwards.  :hm:  Check out info relative to "Annabelle" and Triton's ice volcanoes.

*Wow!  Weird and beautiful.

*Lush starfield, crimson hues.  :up:  Is closest supernova remnant to us.

http://antwrp.gsfc.nasa.gov/apod/ap001204.html]The Circinus Galaxy

*Is a color representative shot.  I'm quite sure I've never seen this pretty galaxy before.  Unusual colors.  "Although only 15 million light years distant, the Circinus Galaxy went unnoticed until 25 years ago because it is so obscured by material in the plane of our own Galaxy."

*That's what I'd call "utterly alien."  :-\  I've seen lots of Galileo pics of Ganymede, but not sure about this one.

Previously I posted an article about ancient star dust well here are a few more follow on articles.

http://story.news.yahoo.com/news?tmpl=s … Scientists zeroing in on source of cosmic rays

*Good grief, I began typing "Astronauts..."  :-\  Gettin' my wires crossed. 

Max Planck Institute mentioned in conjunction with this; it's been in a news a lot lately, it seems.

An international team of astronomers believe they have solved a mystery that has been perplexing scientists for 100 years -- the origin of cosmic rays.

*Four 'scopes in Africa used in this study.  First time to take an image of the source.

*If you're wondering about Easter egg colors in the pic, it's because "the observation was taken in near-infrared light."   Taken March 2004.

Re: New Discoveries *3* - ...MORE deep space, extraplanetary, etc.

http://skyandtelescope.com/news/article … ]Asteroids Tell Tale of Jupiter Migration

In 1984 astrophysicists wrote a seminal paper arguing that the outer planets of the solar system migrated from where they formed to where they are today.

*Mentions Hilda asteroids, of which there are approximately 700.  They're fixed in a 3:2 mean-motion resonance with Jupiter.

Fernández and Ip showed that Jupiter must have launched more bodies outward than inward. Some of the outward-bound objects ended up in the Oort Cloud; others were thrown into interstellar space. In response, Jupiter must have migrated inward by perhaps 0.2 astronomical unit (20 percent the average Earth-Sun distance) over the course of about 100,000 years.

*Article also mentions items of interest regarding http://www.newmars.com/forums/viewtopic … 11]Cassini  (sorry...just in case any newcomers read this, they'll know we have a thread already established for Cassini and Huygens) -- then en route to Saturn and passing Jupiter, of course.  :up:

But tiny Cassini pulled on mighty Jupiter too, decreasing the planet's orbital momentum by a paltry 1 meter per 6 trillion years. The planet drifted inward by an amount so tiny it would be impossible to measure with a microscope.

*Now THAT is amazing.

That might not sound like much, but in the early days of the solar system, the outer planets experienced trillions of close encounters with small, icy planetesimals. While any one encounter had a negligible effect on a planet, they added up.

::EDIT::  A post beneath this one apparently disappeared.  Let's please discontinue this thread; it might collapse next.  New Discoveries *4* has been started; please use it from now on.  Thanks
