Comet Machholz through UV Eyes

[attachment=0]Machholz-fd-move-masked-backsub.jpeg[/attachment][/i]

This image was recorded by the Galaxy Evolution Explorer (GALEX) (http://www.galex.caltech.edu/index.html) at far ultraviolet wavelengths (135 -- 750 nm), where atomic carbon has two bright emission features. Unlike dust, which is pushed away from the comet by solar radiation pressure to create the characteristic white tail that is associated with comets, carbon, like most atoms and molecules is not big enough to receive any push. Carbon therefore floats away from the comet more-or-less uniformly in all directions, forming a spherically symmetric envelope, or "coma." The carbon coma is detected to distances of over 1 million km from comet Machholz.

A team of researchers led by Jeff Morgenthaler at the Planetary Science Institute (http://www.psi.edu) used the fall-off of the carbon emission as a function of distance from the comet to measure how long the average carbon atom lives in interplanetary space before it is ionized. The answer: one to two weeks. This is a long time, but only about half as long as previously thought. The shorter value implies that previous measurements of the amount of carbon coming from comets may have been too large. This might affect theories about the formation of comets in the early solar system. ~ Jeff Morgenthaler

H. Boffin, I wasn't going to comment here but at the ESO homepage (since I saw that your image was originally made at ESO), but I couldn't find your image at ESO's homepage. So I have to ask you here. The colors of this newly discovered planetary are unusual. The inner part of the planetary is brilliantly yellow, and there is an apparent grass-green disk with two brilliantly pink spots on either side. In trying to understand the colors, I checked out the colors of the background stars. The color of the stars appeared very normal, except that there were no bluish stars there at all.

So could you please tell me what filters you used to produce the image, and what colors you assigned the images taken through different filters?

Solstice Total Lunar Eclipse

Copyright 2010 Jerry Lodriguss


This is an illustration I put together to show what the starfield and deepsky field will look like near the Moon at mid-totality during the lunar eclipse on December 21, 2010.

Click on the image above for a higher-resolution version and more information and identifications with a mouse over.

It shows the eclipsed Moon in Taurus at 8:16:57 Universal Time (3:16:57 am est).
