Fahrenheit 451 is a 1953 dystopian novel by American writer Ray Bradbury. [4] It presents a future American society where books have been outlawed and "firemen" burn any that are found. [5] The novel follows in the viewpoint of Guy Montag, a fireman who soon becomes disillusioned with his role of censoring literature and destroying knowledge ...
Venus's atmosphere is composed of 96.5% carbon dioxide and 3.5% nitrogen, with other chemical compounds present only in trace amounts. [1] It is much denser and hotter than that of Earth; the temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (1,350 psi), roughly the pressure found 900 m (3,000 ft) under water on ...
The highest point on Venus, Maxwell Montes, is therefore the coolest point on Venus, with a temperature of about 655 K (380 °C; 715 °F) and an atmospheric pressure of about 4.5 MPa (45 bar). [ 126 ] [ 127 ] In 1995, the Magellan spacecraft imaged a highly reflective substance at the tops of the highest mountain peaks, a " Venus snow " that ...
The story is about a class of students on Venus, which, in this story, is a world of constant rainstorms, where the sun is only visible for two hours every seven years.. One of the children, Margot, moved to Venus from Earth five years earlier and is the only one who remembers the sun, since it shines regularly on Earth.
In 1962, Mariner 2, the first successful mission to Venus, measured the planet's temperature for the first time, and found it to be "about 500 degrees Celsius (900 degrees Fahrenheit)." [ 14 ] Since then, increasingly clear evidence from various space probes showed Venus has an extreme climate, with a greenhouse effect generating a constant ...
The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990–1994 Magellan mission, is centered at 180 degrees east longitude. The geology of Venus is the scientific study of the surface, crust, and interior of the planet Venus. Within the Solar System, it is the one nearest to Earth and ...
Venus's atmosphere consists mostly of carbon dioxide. Because nitrogen and oxygen are lighter than carbon-dioxide, breathable-air-filled balloons will float at a height of about 50 km (31 mi). At this height, the temperature is a manageable 75 °C (348 K; 167 °F).
Venus in real colors, processed from clear and blue filtered Mariner 10 images. Observations of the planet Venus include those in antiquity, telescopic observations, and from visiting spacecraft. Spacecraft have performed various flybys, orbits, and landings on Venus, including balloon probes that floated in the atmosphere of Venus.
