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[..
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[..
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[..
GIANT COMETS — MESSENGERS OF LIFE AND DEATH William P. Napier (Appeared in an anthology: “God, the universe and men – Why do we exist?” (ed. Wabbel, T.D.), Patmos, Dusseldorf, 2003 (original in German). A Neolithic comet Comets are jokers in the celestial pack. They irrupt, usually without forewarning, into the orderly progression of[..
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[..
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[..
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[..
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[..
Paul Heinrich over at the Hall of Maat provides some fine links on the big cold bangs(s): Direct Links to “Tunguska type blast detected in Antartica” Papers and Articles Below are the direct links to the Antarctica Tunguska articles and papers: Articles are: Clues to Antarctica space blast by Paul Rincon BBC News, [news.bbc.co.uk] Antarctica[..
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[..
Here’s the full press release about WISE mission finding dark comets. WISE spies a Comet With its Powerful Infrared Eye, NASA\Jet Propulsion Laboratory, Feb 11, 2010 NASA\JPL–NASA’s Wide-field Infrared Survey Explorer, or WISE, has discovered its first comet, one of many the mission is expected to find among millions of other objects during its[..
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[..
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[..
David Nesvorny I might be pushing the publishing envelope here, but this Science paper was available at several locations on the web for free with no sign-in. For the time being it is now on Scribd: Therefore, a wave of micrometer sized Datura particles may have reached Earthonly a few thousand years after the[..
Sterling K. Webb In February, 2006, SWRI published this paper in Science announcing the discovery of an new recent asteroid family associated with the asteroid 1270 Datura: http://www.boulder.swri.edu/~bottke/Reprints/Nesvorny_Vok_Bottke_Science_2006_Datura_breakup.pdf [Tusk will drop on Scribd] A summary of its conclusions: “The newly identified family is a group of six 1- to 2.5-km-diameter asteroids, whose orbits[..
Numerical simulations show that stony meteorites with masses in the 10*8 to 10*11 kg range may undergo total disruption during atmospheric entry in the lower layers of the Earth’s atmosphere, in a similar manner to the Tunguska event that occurred over Siberia in 1908 . Modelling also show that at a later stage of[..
Big news from the recent Lunar and Planetary Conference at the Woodlands in Texas. A excited article from the BBC breaks the cool story. A large space rock may have exploded over Antarctica thousands of years ago, showering a large area with debris, according to new research. The evidence comes from accumulations of tiny meteoritic particles[..
