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 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…

[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…

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…

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…

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…
