Science News: Signs of giant comet impacts found in cores

Copious ammonium may be evidence of a 50-billion-ton strike at the end of the ice age Signs of giant comet impacts found in cores, Science News, March 30, 2010 By Sid Perkins A new study cites spikes of ammonium in Greenland ice cores as evidence for a giant comet impact at the end of the last ice age, and suggests that the collision may have caused a brief, final cold snap before the climate…

NASA continues opaque and clumsy treatment of dark comets and dark asteroids found by WISE

NASA put out another one of those creepy home made news articles today regarding the WISE mission finding dark objects. This one is even more condescending than usual, with the inane lede, “Imagine you are a Brontosaurus….” Well, I am not a “Brontosaurus.” But I am keenly interested in what the hell WISE is finding up there and it is mighty hard to tell given the…

Bang: Two new papers out concerning proposed Younger Dryas Event

Adrian Melott [See here for a news article from December previewing Melott’s March publication.] I’m still unpacking these two brand new papers from Adrian Melott and A.E. Carlson comparing the atmospheric signals of the Tunguska Event and the start of the Younger Dryas, but they appear relatively positive from standpoint of the YDB impact hypothesis. The Melott paper is protected, so…

Tusk prompts Grondine to query Napier on Dark, Dead comets and the effort to find them

From E.P. Grondine on Meteorite List: Following a quote at https://cosmictusk.com from astronomer Bill Napier on the abilities of WISE to detect dead comet fragments, I wrote him asking him about it. As his reply also deals with some meteorites' parent bodies (Tagish Lake being prominent) and the composition of comet cores, I think meteorite list participants should find it of interest, and here…

NASA: Comet launching companion star to sun "Not crazy"

Richard Muller and a Serpent The Nemesis theory — that a dark, comet launching, orbital companion to our sun lurks between our star and others — seems to be gaining traction among those who matter. [Astropbiology Magazine Exclusive: Getting WISE about Nemesis] As the Cosmic Tusk has revealed in earlier posts, NASA appears to be in an exceptionally enlightened mood since the the WISE…

NatGeo TV Rerun: Holocene Working Group and the Thunder Down Under - March 25, 10:00 pm

Here is a good looking television show I missed the first time around. I watched several substantial clips on the the webpage and it appears well done (if a tad bit overwrought like most science TV). I have long cheered the work of Ted Bryant, Dallas Abbott, Slava Gusiakov, Marie-Agnes Courty, Dee Berger, Bruce Masse and the rest. As many readers will know, their efforts dovetail neatly with…

Guest Blog: E.P. Grodine's compilation of The First Peoples' accounts of the YD Impacts

From Man and Impacts in the Americas by E.P. Grondine. See here for Ed’s Dead Car Special! SOME OF FIRST PEOPLES’ ACCOUNTS OF THE YD IMPACTS As far as the 10,900 BCE comet impact event, many of the peoples remembered it. I included some of them in my book “Man and Impact in the Americas”, though at that time (2005) I misdated them to the end paleo at 8,350 BCE, instead of…
