Sorry didn't mean inwards. I'm not sure you are right. I have seen videos that show electrons moving in towards the sun through the outward moving solar wind. Further the solar wind is obviously moving outward to very high latitudes. The three dimensional image reduced to two dimensions in a video would show solar wind moving north from the pole even if not emitted from 85-90 degrees N Lat. It appears as if the corona is different in character at the polar regions from the remainder of solar emissions this is pretty interesting, why.Chris Peterson wrote:It's all moving outwards. This is very obvious in any animated images, as from SOHO. The only plasma that falls back onto the Sun is what is trapped in tightly closed magnetic fields, which are very close to the surface at the scale of this image. Of course, we have a variety of space-borne sensors monitoring solar wind and solar radiation, and it's all moving away from the Sun. As you'd expect, of course, given that there are no forces present to produce motion in the opposite direction.bhrobards wrote:How do you know its "all moving inwards?"

Re: Favorite APOD
Another favorite,due to its obvious bi-lateral symetry, resembling neither explosion or gravitational effects. The structure of the wings resemble nothing so much as a flowing glow mode plasma and Z pinch in the lab. Particularly the feathery ends of the inner sheaths.

Re: Favorite APOD
maybe not quite relevant -however -for some time I have enjoyed putting the APOD pictures on my desktop background -switching around whenever a really fine juicy one showed up. This option no longer appears on the menu items. Did you change this option or has something happened with my browser program????

Re: Favorite APOD
Thanks Bystander,
Hmmmm. Yesterday the possibility was back on the menu selection after right clicking on the picture - today it is gone again. There but not in bold and therefore not clickable. Dunno. I can still get pics onto the desktop background by saving them first etc . Not a big deal The computer seems to have more of a mind of its own by the hour.

I am so impressed seen here. Thank you for great pictures
Re: Favorite APOD
Hi!
My favourite is one of the last days:
Sagittarius and the Central Milky Way
Rob Gendler has - as usual - done a very good job!
But I think every APOD is very well!! 8)

This is one of my faves of the central region. The enlarged version is truely amazing, especially that "Swirling Vortex of Doom" in the lower right corner.

Re: Favorite APOD
well, I found this web on June 8th, 2009. Since then, I have never missed any picture.
In my opinion, it is really hard to say which one is the best, but the one that gave me the deepest impression was this~

Re: Favorite APOD
My favorite is the Carina Nebula. A cropped version of my favorite version appeared on April 25, 2007 and on other days I think, but here's the full version:
http://heritage.stsci.edu/2007/16/index.html
I especially like the Herbig-Haro object on the right side, about three quarters through the image to the right. It looks like a demon or ninja or something, so I cropped it, rotated it a little, and I'm using it as my desktop. Is there any detailed information about this particular structure anywhere?

<<An ancient Japanese legend promises that anyone who folds a thousand origami cranes will be granted a wish by a crane, such as long life or recovery from illness or injury. The crane in Japan is one of the mystical or holy creatures (others include the dragon and the tortoise), and is said to live for a thousand years. The play A Thousand Cranes, by Kathryn Schultz Miller, dramatizes the story of little Sadako Sasaki of Hiroshima, who tried to stave off her death from radiation sickness by making one thousand origami cranes. Her classmates and other friends finished them for her after her death.>>

Re: Favorite APOD
My favorite is fairly recent:
http://antwrp.gsfc.nasa.gov/apod/ap081212.html
I grew up in the Santa Clara Valley, many years ago, and Lick Observatory (on Mt. Hamilton) was always on my horizon, so I've actually seen moonrise behind it more than once (never had the camera to photograph it, though). I've been to the observatory in person 3 times (and got to look through some of the telescopes once), and it's fascinating. Note, there's a website with 2 webcams (HamCam1 and HamCam2) that refresh the picture every 3 minutes and play back a "movie" of yesterday's pictures ... great fun.
[Later addition: Whoa, the web page linked to above also has a daily night sky movie. Meteor shower fun!]

Re: Favorite APOD
One of my favorites is To Fly Free in Space. It reminds me of the Discovery Channel commercial which I also like.
I've created a page Popular APOD Images that shows popular APOD images according to digg.com.

Well done KJackson! I loved that page. Wasted away half an hour of my time so it did. My favourite is still the sombrero galaxy, or the pillars of creation.

Wallpaper
By far the best wallpaper I have ever seen is the most recent image on APOD of the icelandic volcano, absolutely stunning. Now that I have seen it and applied it to my desktop I have no need for the above sites thank you.

Re: Favorite APOD
Hi!
I will add today's APOD to the list of favourites. The Faces of Mars. I really like the idea of letting children paint the planets. It helps increasing the fascination on the universe. The children of today are the (possible) astronomers of tomorrow!
