Nuclear Thermal propulsion Unlike most things at Beyond NERVA, the nuclear thermal rocket (NTR) has been built and tested by both the US and the USSR. Both programs looked at a solid core NTR, the simplest type of nuclear rocket. In a nuclear thermal rocket, the heat from a reactor is used to directly heat a propellant,Seguir leyendo


That is what antimatter can do. Annihilating a kilogram of antimatter will give out about ten billion times the amount of energy released when a kilogram of TNT explodes. Under suitable circumstances a proton can change into a neutron and emit energy some of which materializes as a positron, similar to what happens in theSeguir leyendo

the Tunguska large explosion 1908 The Tunguska event was a large explosion that occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai), Russia, on the morning of 30 June 1908 (NS).[1][2] The explosion over the sparsely populated Eastern Siberian Taiga flattened 2,000 square kilometres (770 square miles) of forest, yet caused no known human casualties. The explosion is generally attributed to the air burst of a meteor. It is classified as an impactSeguir leyendo


magnetar o magnetoestrella

Un magnetar o magnetoestrella es una estrella de neutrones alimentada con un campo magnético extremadamente fuerte. Se trata de una variedad de púlsar cuya característica principal es la expulsión, en un breve período (equivalente a la duración de un relámpago), de enormes cantidades de alta energía en forma de rayos X y rayos gamma. LosSeguir leyendo
