Good observation, BMA. My first impression is of a globular galaxy set spinning .. perhaps the spin would gather hydrocarbon molecules and dust drifting through space. Perhaps a river-like current of (theoretical) Dark Matter flowing along one edge of the galaxy would set it spinning. My thoughts are musings only of course.

Hello All,

BMAONE23, especially!

This APOD seems to me to bare a striking resembelance to M104 as it might appear from above

I've stated in the past that M104..... IS my favorite Galaxy, it was NOT an easy decision to arrive at (to say the least!). I've had it as my wallpaper for months now and gave my reasons on the "Favorite APOD" topic. So.....what was this? Some kinda hairbrained scheme to pry ole' astrolabe out of the shadows or some such machination Mr. B?

BTW, other than the fact that NGC 7049 is more the size of our own Milky Way than the realitively petite M104 I honestly couldn't agree with you more. The very thought crossed my own mind the second I saw NGC 7049's image. Very happy indeed someone else noticed .

P.S. Ari, mopedaki is mopedara!

I have to agree with your special regards to M104 It has been my desktop for about 2 years now. I occasionally change images but I always return to it.

You can have this on your desktop, too. See http://www.spacetelescope.org/images/ht ... 0905a.html

What exactly is dust made up of? (I trust it is not what I whisk away from shelves and furniture.) Composition? Size?

Aggregated non-ionized atomic and molecular material less than 0.1 mm in size, made from mostly lighter elements and simple molecules. See Cosmic Dust.

They seem very different to me. M104 shows a typical sort of dust lane, although more prominent than many. That is, we see dust that is right in the plane of the galaxy, and is apparent because when we see it edge on it is thick enough to significantly attenuate the light from the galaxy. NGC 7049 shows a ring of dust well inside the disc of the galaxy, and apparently very thick. Usually, dust isn't concentrated this way in elliptical or spiral galaxies. Lots of edge on galaxies are similar in appearance to M104, but I don't know of anything else that looks like NGC 7049.

Hello All,

Good comments regarding this structure using M104 comparisons. Orin, I don't know about BMAONE23 but the image you posted is the one on my desktop. I believe it to be still the most recent using the current enhancement capabilities the APOD folks (or TPTB) now possess. Until this image I always saw the ones where M104 looked more like a ball of light and was constantly amazed when it was stated that the ball was actually billions of stars.

It's perhaps easy for one to imagine how remixed images like http://antwrp.gsfc.nasa.gov/apod/ap080308.html can impact one's ideas after seeing only the pre-remixed images for a time. Good stuff to be sure.

It's indeed amazing that the glow of light surrounding a galaxy can be billions of stars. 8) Wouldn't it be nice to be able to zoom in enough to see all the individual stars that make up a distant galaxy. Let alone; astronomers are finally in the last few years able to distinguish planets around nearby stars.

<<The Hubble Space Telescope image of NGC 7049 in the southern sky constellation of Indus. NGC 7049 is the "brightest" of the Indus triplet of galaxies (NGC 7029, 7041, 7049). Bright Cluster Galaxies are among the most massive galaxies in the universe and are also the oldest. They provide astronomers the opportunity of studying the many globulars contained within them. NGC 7049 is hybrid galaxy, it is somewhat like an elliptical and somewhat like spiral. It also unusual in that remarkable dust lanes can be seen swirling about its bright central core. Generally these are seen in much younger galaxies with star forming regions.>>

<<The [Indus] constellation was one of twelve created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman and it first appeared on a 35-cm diameter celestial globe published in 1597 (or 1598) in Amsterdam by Plancius with Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. Plancius portrayed the figure as a nude male with arrows in both hands but no bow.

Epsilon Indi is one of the closest stars to Earth, approximately 11.82 light years away. The system has been discovered to contain a pair of binary brown dwarfs, and has long been a prime candidate in SETI studies.>>

Hubble Scores a Ring
Written by Anne Minard April 7th, 2009

<<The Hubble Space Telescope has captured a new image of NGC 7049, a mysterious looking galaxy that blurs the boundary between spiral and elliptical galaxies. The image was taken by the Advanced Camera for Surveys on Hubble, which is optimized to hunt for galaxies and galaxy clusters in the remote and ancient Universe, at a time when our cosmos was very young.

NGC 7049 is found in the constellation of Indus, and is the brightest of a cluster of galaxies, a so-called Brightest Cluster Galaxy. They represent some of the oldest and most massive galaxies, and they allow astronomers to study the elusive globular clusters lurking within.

Globular clusters are very dense and compact groupings of a few hundreds of thousands of young stars bound together by gravity. The globular clusters in NGC 7049 are seen as the sprinkling of small faint points of light in the galaxy’s halo. The halo – the ghostly region of diffuse light surrounding the galaxy – comprises myriad individual stars and provides a luminous background to the remarkable swirling ring of dust lanes surrounding NGC 7049’s core. The dust lanes appear as a lacy ring.>>

Some words just look strange in print. I'd like to buy another vowel.
