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.

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…
