متن کاملOut of Africa: Radarclinometry of the Sand Seas of Namibia and Titan
Introduction: Recent observations by the Cassini spacecraft show widespread regions of longitudinal dunes on Saturn’s moon Titan [1]. The exact composition of the dunes is not known, but its radar and infrared return suggest an organic component [2]. Given the broad extent of the dunes (they cover 40% of Titan’s equatorial areas), they constitute an important portion of Titan’s overall organic ...
متن کاملThe sand seas of Titan: Cassini RADAR observations of longitudinal dunes.
The most recent Cassini RADAR images of Titan show widespread regions (up to 1500 kilometers by 200 kilometers) of near-parallel radar-dark linear features that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth. The Ku-band (2.17-centimeter wavelength) images show approximately 100-meter ridges consistent with duneforms and reveal flow interactions with ...
متن کاملThe Holy Quran and Science on Seas
God almighty has stated the importance of sea in various verses of the holy Quran. Since more than 2500 kilometers of the borders of Iran includes sea waters, attention to Quran’s statements about sea is an important duty while human life completely depends on the right knowledge and exploitation of this God-given resource. The word “Bahr” which means sea has been mentioned in 32 verses of Qura...
متن کاملThe Thermosphere of Titan
The diurnal variation of the vertical structure of Titan's thermosphere is calculated through simultaneous solution of the equations of heat transfer and hydrostatic equilibrium. The temperature and density profiles are found above the mesopause. The dynamical response of the thermosphere to heating is for the most part neglected. Nevertheless, we are able to draw some interesting qualitative a...
