The 1908 June 30 Tunguska Event (TE) is one of the best studied cases of cosmic body impacting the Earth with global effects. However, still today, significant doubts are casted on the different proposed event reconstructions, because of…
The Tunguska explosion occurred in the morning of June 30, 1908, in Central Siberia, some 800 km NNW from Lake Baikal. It devastated the forested area of 2150 sq. km, flattening and scorching some 30 million trees. Before this, a luminous…
Till now there is no solid scientific proof for any of the numerous hypotheses proposed for the Tunguska 1908 event. Regarding the most popular "spacebody infall" interpretation it is reasonable to compare the Tunguska event with the 2013…
Historically there were two main reasons to assign the 1908 Tunguska event to a spacebody infall: a) newspaper notes about a fall of a meteorite near the town of Kansk (later claimed to be false); b) eyewitnesses reports about seeing…
It is suggested that the Tunguska event in June 1908 cm-large was due to a cm-large ball of a condensate of bound states of 6 top and 6 anti-top quarks containing highly compressed ordinary matter. Such balls are supposed to make up the…
This paper is a continuation of a series of works, devoted to various aspects of the 1908 Tunguska event. In this paper its author would like to draw attention to some geophysical aspects of the 1908 Tunguska event. A review of some…
The well-known Tunguska-1908 phenomenon (TP) problems (the fast transfer of the kinetic energy of the meteoroid W~10-50 Mt TNT to air, with its heating to T>10^4 K at an altitude of 5-10 km, the final turn of the smoothly sloping, ~0-20^o…
This paper is a continuation of a series of works, devoted to various aspects of the 1908 Tunguska event. In the late June - early July, 1908 there were various optical anomalies in the atmosphere. Early the Author already considered…
This paper is a continuation of a series of works, devoted to various aspects of the 1908 Tunguska event. This usually refers to an explosive phenomenon associated with the appearance of a forestfall, named nowadays as the Kulikovskii one.…
This paper is a continuation of a series of works, devoted to various aspects of the 1908 Tunguska event. A large number of hypotheses about its causes have been put forward already. However, so far none of them has received convincing…
On June 30th, 1908, there was a massive explosion over Tunguska, in Central Siberia. A number of scientists have proposed that this Tunguska Phenomenon was caused due to the tangential passage of an astral body that grazed the Earths'…
We have studied the conditions of through passage of asteroids with diameters 200, 100 and 50 m, consisting of three types of materials -- iron, stone and water ice across the Earth's atmosphere with the minimum trajectory altitude 10--15…
The reason for the horizontal turn of the Tunguska-1908 bolide trajectory remains difficult to understand. It finds explanation, however, in the New Explosive Cosmogony of minor bodies as having been caused by an explosion of a part (M up…
On June 30, 1908, at about 0h 14.5m UTC, the Tunguska Event (TE) occurred, most likely caused by the fall of a small stony asteroid of about 50-80 meters in diameter over the basin of the Tunguska River (Central Siberia). This paper will…
Mirror matter is predicted to exist if parity (i.e. left-right symmetry) is a symmetry of nature. Remarkably mirror matter is capable of simply explaining a large number of contemporary puzzles in astrophysics and particle physics…
The 1908 Tunguska event is used to be associated with a forestfall named after its first scientific researcher -- Leonid Kulik.However association of the Kulikovskii forestfall with the events in the morning of June 30, 1908 is based only…
This monograph presents a study of the nature and origin of meteorites, asteroids and comets; and of the consequences of encounters of these cosmic objects with the Earth. The purpose of this monograph is mainly of divulgation for…
This paper is a continuation of a series of works, devoted to various aspects of the June 30, 1908 Tunguska event. In those days, various sky optical anomalies were observed over a large area. In the presented paper, the main focus is on…
On 2013 February 15 a small asteroid rammed against the atmosphere above the region of Chelyabinsk in Russia, producing the most powerful superbolide since the Tunguska event in 1908. Lacking proper astrometric observations, the pre-impact…
The author suggests new vision of mechanism of initiation of life on the planets after Tunguska similar impacts. This mechanism takes into consideration not only incoming cosmic organic substance but also information, which is connected to…
