		<description>More on Name.

You think enough about the sun in this picture above and the deeper one&#039;s  thinking becomes in manifesting information about the &quot;sterile neutrino&quot; and gravity?

 While it had only been high energy valuations, what about a target of 12.7 billion years ago?

Would this allow research of asymmetry, from GRB to account for the &quot;sterile neutrino&quot; manifesting as weak field gravity consideration?

&lt;a href=&quot;http://www.fnal.gov/pub/news03/update_archive/update_10-10_10-13.html&quot; rel=&quot;nofollow&quot;&gt;Current evidence shows that neutrinos do oscillate, which indicates that neutrinos do have mass. The Los Alamos data revealed a muon anti-neutrino cross over to an electron neutrino. This type of oscillation is difficult to explain using only the three known types of neutrinos.&lt;/a&gt;</description>

		<description>Just found a photo of: &quot;The moon&#039;s shadow, as seen in muons 700m below ground at the Soudan 2 detector.&quot;

http://en.wikipedia.org/wiki/Image:Moons_shodow_in_muons.gif

See also: http://en.wikipedia.org/wiki/Muon

Seems to go nicely with JoAnne&#039;s neutrino photo of sun!

		<description>Some do not believe the internet to be a powerful tool?

The basis of this post is the affront to the way we see. An &quot;affront&quot; to the &quot;Trouble with Physics.&quot;

For example, the &lt;a href=&quot;http://glast.sonoma.edu/index.html&quot; rel=&quot;nofollow&quot;&gt;Window on the Universe?&lt;/a&gt;&quot; Some like to speak about &quot;Glast&quot; while others will look at JoAnnes image above. It is about the deeper perception developing(our window), and not just about the &quot;energy&quot; although this governs the thought processes?

LIGO may say they are the window? And we await for compilation of the data?</description>

		<description>More on name.

Possibly from a generalized &quot;point of view&quot; the concept of the &quot;Navier-Stokes equations&quot; can be applied here?

Maybe it is as Einstein relayed that the ancients had a &quot;purity of thought&quot; based on the fluidic notions of the QGP??</description>

		<description>Out of interest, does anybody know the source of the huge horizontal bar across the image?  I assume it is to do with the detector rather than something physical, but would like to make sure.</description>

		<description>Mollishka:  Thanks for making me smile!

Rob and Macho:  Thanks for answering nc&#039;s questions while I was on a cross-country flight home.

nc:  To borrow a phrase from Sean - maybe you ought to switch to decaf.

Louise:  NASA and DOE have appointed a National Academies panel to recommend whether LISA (space-based gravity wave probe), CON-X (space-based X-ray telescopes to study blackholes) or JDEM (joint dark energy mission) should be launched.  NASA has the funds to do exactly *one* of these projects.  The panel is just being formed now and will report a year from now.</description>

		<description>From comments I heard at HEAD last week and Salamon&#039;s comments yesterday, the Dark Energy Mission is likely to be indefinitely deferred.

		<description>nc -- the blurriness of the image isn&#039;t scatter due to the Earth&#039;s atmosphere.  It represents the limitation of the spatial resolution of the detector.  It&#039;s analogous to the fact that there is some width (and structure) in images of point-sources observed with the Hubble Space Telescope.

The brightness profile is simply the &quot;point spread function&quot; of the detector.  It&#039;s noting particularly deep or meaningful as far as actual astronomy goes.  It is cool, though, that the Sun can be localized!  Many neutrino detetors over time haven&#039;t had &lt;i&gt;any&lt;/i&gt; spatial resolution; they can tell you that neutrinos are there, but not where they&#039;re coming from.  (Amanda and Ice Cube will have better spatial resolution than Super-K, I think.)

Re: Neutrino Oscillations, they have been confirmed to exist.  The observational result is five or so years old now.  The Solar Neutrino Problem has indeed been solved; in between the Earth and the Sun, the neutrinos emitted originally as electron neutrinos decohere in flavor, so by the time they get to the Earth you may observe an electron, mu, or tau neutrino.

It represents the limitation of the spatial resolution of the detector.  It&#8217;s analogous to the fact that there is some width (and structure) in images of point-sources observed with the Hubble Space Telescope.</p>
<p>The brightness profile is simply the &#8220;point spread function&#8221; of the detector.  It&#8217;s noting particularly deep or meaningful as far as actual astronomy goes.

		<description>By relative intensities, I mean what is the difference in flux between white and red, for example.  Another question springs to mind: what about the solar neutrino problem?  There was an issue a few years back that neutrinos were thought by some to oscillate between different types to explain the low detection rate, so there are serious questions in this area.

If the sun is really small in the middle of the white area, then the gradual fall in intensity around it shown by the coloured areas is interesting, because you don&#039;t expect any scatter by the earth&#039;s atmosphere or the detection instrument (because of the small cross section for any interaction by neutrinos).  :-)</description>

		<description>thanks macho!  That answers the main question!  ;-)

N Peter Armitage: everyone knows neutrinos are weakly interacting, the image should at least have a scale decoding the colours as intensities (even if only a relative scale).  Artificial colours are fine if you tell people what they correspond to.  BTW, you don&#039;t have to be &quot;grumpy&quot; just because you like science!  ;-)</description>

		<description>&gt;Badly labelled illustrations and figures from astronomy actually put people off, &gt;because you can&#039;t learn a thing from them! Thanks.

Mr. nc,  (or dr. nc?) why so grumpy?   It is not a figure or illustration, it is art based on the physical world.

You learned neutrinos can pass through the earth relatively unimpeded didn&#039;t ya?  Not bad for a piece of art.</description>
