Click on image for full resolution. New research funded by NLSI theorizes that our early Earth and moon were perhaps created in a different manner than has previously been believed. Image credit: NASA New research, funded by the NASA Lunar Science Institute (NLSI), theorizes that our early Earth and moon were both created together in a giant collision of two planetary bodies that were each five times the size of Mars. This new theory about how Earth’s moon formed is challenging the commonly believed “giant impact hypothesis,” which suggests that Earth's moon formed from a colossal impact of a hypothetical planetary embryo, named Theia, with Earth, early in our Solar System's history. “Our understanding of the solar system is constantly being refined with each new discovery.

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.
