The Rupununi event

The Rupununi event I now move on to the suspected explosion over British Guyana in 1935. The main source for information on this event is a story entitled Tornado or Meteor Crash? in the magazine The Sky (the forerunner of Sky and Telescope) of September 1939(5). A report from Serge A. Korff of the Bartol Research Foundation, Franklin Institute (Delaware, USA) was printed, he having been in…

THREEPEET!!!: Jupiter takes third hit in two decades; second in a year

Astronomers around the world are shocked — shocked! — to once again witness a world busting impact on Jupiter. Regular readers of the Tusk know better. Notwithstanding patronizing dismissals urging us all to “move along, nothing to see here,” we know that the solar system is a far more dangerous place than acknowledged by the wise men and their calculations. We know…

Journal of Cosmology (Part I): Napier

Crumbling Comet Schwassmann-Wachmann 3 Approaches Today I added a link to the ‘Great Link’s on the right sidebar to a fine ET extinction and Younger Dryas Boundary round-robin thrown last year by the Journal of Cosmology. The Journal solicited a number of distinguished contributers both supportive and dismissive of the idea the earth encountered a game-changing cosmic…

Smoke Linked to Gun: Napier upheld by Nesvorný and Jenniskens on Zodiacal Cloud and short-period Comets

Richard Kerr, the oldest rat in the barn over at Tusk competitor Science Magazine, has written a disturbingly matter-of-fact piece reporting the myth busting work of David Nesvorný and Peter Jenniskens (hereafter N&J) on the source of Interplanetary Dust and the Zodiacal Cloud. N&J are the same fellows who last month deduced massive ancient meteoritic airburts in Antarctica from ice…

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…

Predictive paper: Nesvorny, Bottke, Vokrouhlicky used astronomy to predict Antarctic stratigraphy

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 formation of the Datura cluster. Signs of this event may be found by analyzing tracers…

The paper: Antarctic Blast evidence

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 [12]. Modelling also show that at a later stage of a Tunguska-like impact a plume of hot vapour and ablation debris is…

Bang: Ancient Antarctic Blast detected by University of Siena scientists

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 and a layer of extraterrestrial dust found in…
