There Are X-Rays Coming From Pluto And We Still Don't Know What's Causing It

https://www.sciencealert.com/there-are- ... causing-it

Quote:
"Given that most pre-encounter models of Pluto's atmosphere had predicted it to be much more extended, with an estimated loss rate to space of ~1027 to 1028 mol/sec of N² and CH4… we attempted to detect X-ray emission created by [solar wind] neutral gas charge exchange interactions in the low density neutral gas surrounding Pluto," they wrote.

However, after consulting data from the Advanced CCD Imaging Spectrometer (ACIS) aboard Chandra, they found that x-ray emissions coming from Pluto were greater than what this would allow for.

New Horizons Unveils New Maps of Pluto, Charon on Flyby Anniversary

http://www.astrowatch.net/2017/07/new-h ... pluto.html

Quote:
"The complexity of the Pluto system — from its geology to its satellite system to its atmosphere— has been beyond our wildest imagination," said Alan Stern, New Horizons principal investigator from the Southwest Research Institute in Boulder, Colorado. "Everywhere we turn are new mysteries. These new maps from the landmark exploration of Pluto by NASA's New Horizons mission in 2015 will help unravel these mysteries and are for everyone to enjoy."

Scientists Explain Pluto's Skyscraper-Sized Ice Blades

Quote:
First observed by the New Horizons spacecraft in 2015, the strange spiky features are likely formed from sublimating methane.

Why it’s good news that Pluto doesn’t have rings

Quote:
New Horizons’ next destination might be ring-free, too, promising a safe passage for the spacecraft

Who's watching the World Series? Not me! But there's something astronomical going on besides the Houston Astro's name.

Los Angeles Dodgers's pitcher Clayton Kershaw's great-uncle was Clyde Tombaugh!

The Global Color of Pluto from New Horizons

http://iopscience.iop.org/article/10.38 ... a965b/meta

Quote:
The New Horizons flyby provided the first high-resolution color maps of Pluto. We present here, for the first time, an analysis of the color of the entire sunlit surface of Pluto and the first quantitative analysis of color and elevation on the encounter hemisphere. These maps show the color variation across the surface from the very red terrain in the equatorial region, to the more neutral colors of the volatile ices in Sputnik Planitia, the blue terrain of East Tombaugh Regio, and the yellow hue on Pluto's North Pole. There are two distinct color mixing lines in the color–color diagrams derived from images of Pluto. Both mixing lines have an apparent starting point in common: the relatively neutral-color volatile-ice covered terrain. One line extends to the dark red terrain exemplified by Cthulhu Regio and the other extends to the yellow hue in the northern latitudes. There is a latitudinal dependence of the predominant color mixing line with the most red terrain located near the equator, less red distributed at mid-latitudes and more neutral terrain at the North Pole. This is consistent with the seasonal cycle controlling the distribution of colors on Pluto. Additionally, the red color is consistent with tholins. The yellow terrain (in the false color images) located at the northern latitudes occurs at higher elevations.

HAPPY 88TH BIRTHDAY, PLUTO!

YOU'LL ALWAYS BE A PLANET TO ME!

Also 88 is a lucky number in Chinese since 8 in Chinese is homophonous with the word for 'wealth' and 'fortune'.

P.S. Mike Brown is a poopyhead.

Quote:
Answer one: It depends.

Answer two: It’s irrelevant.
