This is so cool
NAAS Astronomy Picture of the Day 2016 September 5
What is this meteor doing? Dynamically, the unusually short and asymmetric train may indicate that the sand-sized grain at the center of the glow is momentarily spinning as it ablates, causing its path to be slightly spiral. Geographically, the meteor appears to be going through the Heart Nebula, although really it is in Earth’s atmosphere and so is about one quadrillion times closer. Taken last month on the night of the peak, this meteor is likely from the Perseid meteor shower. The Perseids radiant, in the constellation of Perseus, is off the frame to the upper right, toward the direction that the meteor streak is pointing. The Heart Nebula was imaged in 18 one-minute exposures, of which the unusual meteor streak appeared on just one. The meteor train is multicolored as its glow emanates from different elements in the heated gas.
So very true.

Sad that this is so true...
BERKELEY, CA—Warning society that it has reached a crucial tipping point from which it may never be able to recover, a brittle, yellowing report sitting in the archives of the University of California’s Bioscience & Natural Resources Library reportedly urged readers Friday that “the time to act against climate change is right now.” “Any further delay in ending the international community’s reliance on fossil fuels and reversing global carbon emission trends places the planet on an irreversible path toward climate catastrophe,” read the faded text of the document, whose musty, degrading pages further cautioned that, without “an immediate and concerted worldwide response,” polar ice caps will melt at an accelerating rate and extreme weather events will grow more frequent and destructive.
