Using the results of the dendrochronological analysis (68 tree-ring chronologies), it has been shown that the increase in the annual growth of trees after the Tunguska bolide explosion on June 30, 1908, is observed at a large distance (more than 1500 km) from the explosion site (61° N, 102° E) and covers a huge area of about 2 × 106 km2 (60°–75° N, 80°–110° E). The anomalous growth of the trees was previously reported only for the direct-destruction area (about 2000 km2). A similar result was…

Swarm of fragments from the Tunguska event
The Tunguska event took place on 1908 June 30. It was accompanied by an abnormal effect on the Earth's atmosphere, manifesting itself through ‘white nights’. These nights were associated with a
Changes in the Radial Increment and CO2 Distribution in Larches that Survived the Explosion of the Tunguska Space Body
Abstract A photoacoustic technique was used to analyze gas samples vacuum-extracted from larch discs which survived the explosion of a space body in the region of Podkamennaya Tunguska river in 1908.
Impossible to Disprove Yet Impossible to Believe: the Unforgiving Epistemology of Deep-Time Oral Tradition

Dendrochronology raises questions about the nature of the AD 536 dust-veil event
New evidence is presented which shows the response of a wide grid of tree-ring chronologies to the dust-veil of AD 536, the effects of which were historically recorded in the Mediterranean and

Tunguska Meteor Fall of 1908: Effects on Stratospheric Ozone
The coincidence in time between the observed ozone recovery and the Tunguska meteor fall indicates that the event may provide a test of current ozone depletion theories.
3- to 14-μm Spectroscopy of Comet C/1999 T1 (McNaught–Hartley)
Abstract We report spectroscopy of Comet C/1991 T1 (McNaught–Hartley) at 3–13 μm on January 31.62 and February 1.7 2001 UT (delta=1.29 AU, r =1.40 AU) using the broadband array spectrograph system on
Planetary resources and astroecology. Planetary microcosm models of asteroid and meteorite interiors: electrolyte solutions and microbial growth--implications for space populations and panspermia.
The results show that bioresources in the carbonaceous asteroids can sustain a biomass of 10(18) kg, comprising 10(32) microorganisms and a human population of 10-14, and suggest that protoplanetary nebulae can support and disperse micro organisms and can be therefore effective environments for natural and directed panspermia.
