Doubted Exoplanet 'Back from the Dead'
Excerpt:%%SPIN0%% appearance at data from NASA's Hubble Space Telescope is reanimating the claim that the neighboring star Fomalhaut hosts a massive exoplanet. The research recommends that the planet, named Fomalhaut b, is an uncommon and possibly unique item that is totally shrouded by dust. Fomalhaut is the brightest star in the constellation Piscis Austrinus and lies 25 light-years away. In November 2008, Hubble astronomers announced the exoplanet, named Fomalhaut b, as the first one ever directly imaged in noticeable light around yet another star. The item was imaged just inside a large ring of fragments surrounding but balanced out from the host star. The planet's place and mass-- no even more than 3 times Jupiter's-- appeared just right for its gravity to explain the ring's appearance . Current researches have declared that this planetary interpretation is inaccurate .

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.
