Excerpt:

Millions of eyes followed Venus’ steady June voyage across the sun’s surface, the coal-black dot sailing in front of a blazing golden orb (SN: 6/30/12, p. 11). The spectacle was the second in the recent pair of Venus transits; the first was in 2004. At the beginning and tail end of Venus’ six-hour journey in 2004 — before and after the planet was completely silhouetted by the sun — astronomers saw something they had been hoping for: Faint wisps of Venus’ upper atmosphere winked clearly into view. This year’s event handed scientists another opportunity to learn about Venus’ gaseous clouds, like why they spin faster than the planet itself. “We got a second chance, and we tried to make the best of it,” says Jay Pasachoff, director of the Hopkins Observatory at Williams College in Williamstown, Mass.

Key:

• Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
• The Mean is meant to be an indicator of an individual's average comment sentiment.
• The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
