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…

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…

Viva la Verde! Just in pic of radioactive Mexican green clay

Click for larger image Melissa Scruggs of the U of Missouri gang kindly sent me this tantalizing taste of their recently reported find of a YD-start age radioactive green mat.  She said they have A LOT of samples they are working through and should report their findings in April.   Understandably, they chose to share only a single photo without much context before the results are published.

Great Paper: The case for significant numbers of extraterrestrial impacts through the late Holocene

I love this paper.  It’s in a great journal, chock full of well-sourced, multidisciplinary information, and written by a rock-solid expert in an immensely important field: Dendrochronology.  While other Dendrochronologists signed-up for the terribly political job of attempting to document slow and incremental temperature change over the ages, Mike Baillie became an expert in the…
