With few exceptions, only the arrival of pulp science fiction in the 1950s would reintroduce the genre in Spanish literature. [8] [4] The space opera series La Saga de los Aznar (1953-1958 and 1973-1978) by Pascual Enguídanos received the European SF Award for Best Cycle of Novels at the Eurocon in Brussels in 1978. [9]
The density of matter in the interstellar medium can vary considerably: the average is around 10 6 particles per m 3, [136] but cold molecular clouds can hold 10 8 –10 12 per m 3. [39] [134] A number of molecules exist in interstellar space, which can form dust particles as tiny as 0.1 μm. [137]
An iceberg, which is commonly associated with cold Signal "cold" – unofficial (except recommended by CMAS), it is nonetheless used by many schools of diving and propagated through diving websites as one of the more useful additional signals [1] Goose bumps, a common physiological response to cold, aiming to reduce the loss of body heat in a cold environment A photograph of the snow surface ...
A nurse who moved from sunny Spain to Norway has gone viral for sharing tips and tricks on how she stays warm in the freezing cold. In Norway, the average winter temperature is -6.8° C (19° F ...
Zero kelvin (−273.15 °C) is defined as absolute zero.. Absolute zero is the lowest limit of the thermodynamic temperature scale; a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value.
Currently, the standard space interval, called a standard meter or simply meter, is defined as the distance traveled by light in vacuum during a time interval of exactly 1/299,792,458 of a second. This definition coupled with present definition of the second is based on the special theory of relativity in which the speed of light plays the role ...
In the 18th century, the scientist and naval officer Jorge Juan proposed to Charles III to create an astronomical observatory in Madrid. This became part of a more ambitious project of an urban axis devoted to science, which included the Museo Nacional del Prado (initially planned as Natural Science Museum and Academy of Sciences), the Real Jardín Botánico and the Royal Astronomical Observatory.
Sunshield full-size test for the James Webb Space Telescope. In spacecraft design, a Sun shield restricts or reduces heat caused by sunlight hitting a spacecraft. [5] An example of use of a thermal shield is on the Infrared Space Observatory. [5] The ISO sunshield helped protect the cryostat from sunlight, and it was also covered with solar ...
