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…

New WISE space telescope finds nine dark comets -- and one black comet -- in six weeks

This is not breaking news, but rather a brief breakdown of information gleaned from David Shiga’s great New Scientist article last week regarding the findings of the recently launched WISE infrared space telescope. The information from the article, though unattributed, is presumably from the mission scientists themselves: In its first six weeks of observations, it has discovered 16…

Dead Car Special!: E.P. Grondine offering great book at great price

I am sorry to report that impact researcher, and friend to many on the internet, E.P. Grondine, has fallen on hard times. E.P. has had two calamities, a horrible stroke — and a career as a newspaper science writer. Which is not a popular vocation at the moment. If that’s not bad enough, his car “Betsy” has broken down and he is unable to repair it. What E.P. can do…

New Scientist: WISE mission finding yet more dark, dead comets predicted by Napier

Now visible comet from WISE in infrared In an earlier post I noted that last month NASA had mentioned WISE finding dark and dead comets for the first time (at least as recorded on the Internet). I thought it kind of odd that well into a mission the agency begins speaking of a dangerous phenomena that had not been previously and specifically identified as quarry for the Infrared Telescope. Mind…
