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…

I had the good fortune to meet Michael Davias, the author of the Perigee Zero website, at the AGU Fall meeting last December. Mike has taken the Bay phenomena on-line better than anyone — including me. He has also been fearless in his (well considered) speculation. I have long intended to get Perigee Zero properly linked and posted on the Tusk.
I am particularly interested in posting…

The strike on Jupiter last year raises the likelihood of future impacts by an order of magnitude, says a new study. But what does it mean for the Earth?
Last July, an amateur astronomer noticed that a mysterious dark bruise about the size of the Earth had suddenly appeared on the surface of Jupiter. Within…

Archaeological Perspectives on the ExtraTerrestrial Impact Hypothesis, 12,900 B.P.: A View from Western North America
Terry L. Jones, Ph.D.
Abstract
The 12,900 B.P. extraterrestrial impact hypothesis has been introduced into American archaeology at a time when longstanding explanations for the Paleoindian archaeological record encompassed by the Clovis-first and Pleistocene Overkill theories have…

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…

I often find myself privately obsessed with comparing the Anthropogenic Global Warming (AGW) debate with the far more obscure ET Climate Catastrophe (ETCC) debate — particularly the nature and role of The Skeptic of Mortal Peril in each.
The Skeptic of Mortal Peril in the AGW debate is defined by the fearless pajamaed retirees like Steve McIntyre at Climate Audit. While The Skeptic of…

The Tusk is going slightly off-topic to cover the fascinating discussion of Citizen Castastrophists Hermann Burchard and Han Kloostermann concerning their belief that volcanic hot-spots are caused by impacts in deep time (deep time being the off-topic part).
I’m in Austin, Texas all week at the national swamp swappers conference, which makes me a busy bee. So please excuse the formatting…

Rod Chilton, author of the most recent (and perhaps only) comprehensive review of Younger Dryas science, was kind to contribute this fine critique of David Morrison’s recent paper in Skeptical Enquirer. I am reading Rod’s excellent book and look forward to reviewing it soon:
The debate continues as to the cause of the more than 1,000 year-long cold interval known as the Younger Dryas.

The frequency of impacts of objects of various sizes is known only to limited precisions. In particular, objects up to several meters in diameter explode in the atmosphere without reaching the surface. Although the energy released in these explosions may be many times greater than that released by the Hiroshima bomb, they most frequently occur over the ocean or sparsely inhabited regions of Earth…
