A little interesting about space life.
The harmful effects of radiation are based both on its strength and the time of exposure to its source. Average human would need to spend nearly four months inside the Van Allen belts to accumulate a lethal dose. The astronauts managed to pass through them during less than one hour. Regarding the time spent out of Earth's magnetic field, where the astronauts were exposed to solar radiation, an average human could endure a radiation exposure equivalent to one-way trip to Mars and still not receive a dose which exceeds lifetime levels set up by NASA.

Triton is one of the coldest bodies in our Solar System. In fact, it is so cold that most of its nitrogen atmosphere is condensed as frost, giving its surface a very bright, mirror-like surface, that reflects about 70% of the sunlight that reaches it.
The 'Board of Trustees' in Yangon organises and conducts an official ceremony to celebrate this day in the context of which a huge processions is led around the great gilded 'Shwedagon Stupa'. The people leading this procession are clad in the garb of celestial beings such as 'Thagyamin' (King of Celestials), the 'Galon/Garuda King' (a mythical being half human and half bird) and the 'Naga' (Serpent King). This much to the religious, the commemoration part of the full-moon day of Kason. But what about the anticipating part mentioned earlier?

Earth's Moon was thought to be The Moon--and the only moon--until Galileo Galilei took his primitive telescope up to the roof of his house in Padua in January 1610. Galileo aimed his telescope up to the clear starlit night sky above his home--one of the first to be used for astronomical purposes--and aimed it at the giant planet Jupiter. As a result, Galileo discovered the four large Jovian Galilean Moons, eventually named in his honor: Io, Europa, Ganymede, and Callisto.
Moons are natural satellites that circle around another body that, in turn, circles around its parent-star. The moon is held in place by both its own gravity and the gravitational pull of its planet. Some planets have moons, while others do not. Several asteroids are known to be circled by very small moons, and some dwarf planets--such as Pluto--also have moons. One of Pluto's quintet of moons, Charon, is about half the size of Pluto itself. Some planetary scientists propose that Charon is really a large chunk of Pluto that was torn off in a catastrophic collision with another wandering world long ago. Because Charon is almost 50% the size of Pluto, the two tiny icy bodies are sometimes considered to be a double-planet.
The most popular theory of lunar formation suggests that the Moon was born in a monumental collision between a Mars-size object named Theia and the ancient Earth--and that this ancient smash-up would have melted our primordial planet. This model further suggests that more than 40 percent of Earth's Moon is composed of the debris of the tragedy that was Theia. However, more recent theories indicate that our planet suffered from several giant collisions during its formation, with the lunar-forming crash being the last great grand finale event.
