NASA’s Kepler Detects Potential Evaporating Planet Candidate

The artist's concept depicts a comet-like tail of a possible disintegrating super Mercury-size planet candidate as it transits its parent star named KIC 12557548. At an orbital distance of only twice the diameter of its star, the surface temperature of the potential planet is estimated to be a sweltering 3,300 degrees Fahrenheit. At such a high temperature, the surface would melt and evaporate. The energy from the resulting wind would be enough to allow dust and gas to escape into space creating a trailing dusty effluence that intermittently blocks the starlight. Astronomers may have detected evidence of a possible planet disintegrating under the searing heat of its host star located 1,500 light-years from Earth. Similar to a debris-trailing comet, the super Mercury-size planet candidate is theorized to fashion a dusty tail. But the tail won't last for long.

  • 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.

Saturn Burps After Large Storm | Redux

Saturn Burps After Large Storm

Excerpt:

NASA's Cassini spacecraft has actually tracked the consequences of an unusual huge storm on Saturn. Data reveal record-setting disruptions in the planet's upper atmosphere long after the noticeable signs of the storm mellowed out, in addition to an indication the storm was more forceful than researchers previously thought. Data from Cassini's composite infrared spectrometer (CIRS) instrument disclosed the storm's effective release sent the temperature in Saturn's stratosphere skyrocketing 150 degrees Fahrenheit (83 kelvins) above typical. At the exact same time, researchers at NASA's Goddard Space Flight Center in Greenbelt, Md. , detected a massive rise in the amount of ethylene gas, the origin of which is a puzzle. Ethylene, an odorless, colorless gas, isn't really usually noted on Saturn. On Earth, it is produced by natural and man-made sources. Goddard researchers describe the unmatched belch of energy in a paper to be released in the Nov.

0.178524"This temperature spike is so extreme it's almost unbelievable, especially in this part of Saturn's atmosphere, which typically is very stable," said Brigette Hesman, the study's lead author and a University of Maryland scientist who works at Goddard. "To get a temperature change of the same scale on Earth, you'd be going from the depths of winter in Fairbanks, Alaska, to the height of summer in the Mojave Desert."
