BTW - That oil painting used in the article is by noted classic space artist Chesley Bonestell and was made for a 1950s magazine article and later coffee-table book, "The World We Live In". It depicts the early Earth with a (then) much closer Moon in low orbit. I love Bonestell's work. He did the glass matte landscape paintings for the movies "Destination Moon", "When World's Collide" and "Forbidden Planet" as well as "Citizen Kane" and the flying movie "Only Angels Have Wings".
Though his own art teacher years earlier told him that based on close telescopic observations the areas on the moon where spaceships might eventually land should likely appear soft and flat with gently rolling hills, Bonestell picked the most dangerous areas where craters form tall jagged cliffs. The reason - more dramatic! ;) |
Diversity, independence, innovation and imagination are progressive concepts ultimately alien to the conservative mind.

I think that, more than anything other single factor, gazing at Chesley Bonestell paintings while growing up inspired my love for space and science.

Here's the NASA/JPL article on the "cool stars, different mix" thing I mentioned in my last post.
Along with much the same wording as quoted above, the JPL article says: They found that the cool stars, both the M-dwarf stars and brown dwarfs, showed no hydrogen cyanide at all, while 30 percent of the sun-like stars did. "Perhaps ultraviolet light, which is much stronger around the sun-like stars, may drive a higher production of the hydrogen cyanide," said Pascucci. |

Definitively seems that something is missing. But, damn, that some big error bars... :p |

| Those are the dimly distinguishable bars in the background of the graph? Are they meant to show the margin of error in the data?

Yeo, the vertical bars at the middle of the data points. They overlap everywhere but for the HCN peak. So that is the only statistical difference between the two spectra. |

| Thanks. Looks like the signal they are working with is nearly buried in the noise.

It looks more like the measurements are very variable between each others and/or maybe not very numerous. Which make for bigger confidence intervals... |
