По време на изпълнението на песента “Мама” на концерта на Роджър Уотърс в София думата “Оставка” беше изписана с червени букви на таблото над сцената, веднага след като певецът изрече думите от песента “Мамо, трябва ли да вярвам на правителството.
THE BULGARIAN GOVERNMENT HAS JUST RESIGNED AFTER 421 PAINFUL DAYS IN PATHETIC AGONY.

Titan is the largest moon of Saturn. It is the only natural satellite known to have a dense atmosphere, and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found
Titan is primarily composed of water ice and rocky material. Much as with Venus prior to the Space Age, the dense, opaque atmosphere prevented understanding of Titan’s surface until new information accumulated with the arrival of the Cassini–Huygens mission in 2004, including the discovery of liquid hydrocarbon lakes in Titan’s polar regions.
The atmosphere is largely nitrogen; minor components lead to the formation of methane and ethane clouds and nitrogen-rich organic smog. Titan’s lower gravity means that its atmosphere is far more extended than Earth’s and about 1.19 times as massive. It supports opaque haze layers that block most visible light from the Sun and other sources and renders Titan’s surface features obscure. Atmospheric methane creates a greenhouse effect on Titan’s surface, without which Titan would be far colder. Conversely, haze in Titan’s atmosphere contributes to an anti-greenhouse effect by reflecting sunlight back into space, cancelling a portion of the greenhouse effect warming and making its surface significantly colder than its upper atmosphere.
Titan’s clouds, probably composed of methane, ethane or other simple organics, are scattered and variable, punctuating the overall haze.The findings of the Huygens probe indicate that Titan’s atmosphere periodically rains liquid methane and other organic compounds onto its surface. Clouds typically cover 1% of Titan’s disk, though outburst events have been observed in which the cloud cover rapidly expands to as much as 8%. One hypothesis asserts that the southern clouds are formed when heightened levels of sunlight during the southern summer generate uplift in the atmosphere, resulting in convection. This explanation is complicated by the fact that cloud formation has been observed not only after the southern summer solstice but also during mid-spring.

Anybody interested in winning a ticket to space?
Big news to kick off the weekend, stay tuned ;)
My first and probably last hand drawn GIF. Yay.
TONIGHT IS THE NIGHT. 400+ ATTENDING SO FAR.
The American Astronautical Society presenting it’s Lifetime Achievement Award to Cal Tech/JPL’s Edward Stone, who is also the Lead Project Scientist for the Voyager spacecraft!
Following Ed Stone, our film, “I want to be an Astronaut” will be shown, accompanied with a panel discussion afterward with NASA’s Charles Bolden, John Grunsfeld, AIAA’s Sandra Magnus, and others!
Tonight’s event will take place from 6pm-9pm EST inside Washington DC’s Historic National Academy of Sciences Building.
COMMENCE COUNTDOWN TO LIFTOFF….
