Far away solar system with two Earth-like planets

Scientific looking the Universe have found a new solar system around Kepler-62. and there is at least five planets which orbit around the star. But the great news is that and two of them are Earth-sized and orbit the star in its habitable zone.
The two planets, called Kepler-62e and Kepler-62f, are both bigger than Earth, but not by much; they are 1.6 and 1.4 times the Earth’s diameter, respectively. Kepler-62e orbits the star every 122 days, while Kepler-62f, farther out, takes about 267 days.
Given the temperature and size of the parent star, this means that both planets are inside the zone around the star where water on the surface could be a liquid. 

One of the reasons the scientific look out into the Universe is to learn more about ourselves. Certainly, finding planets that are different than ours provides us with context, a there-but-for-the-grace-of-God-go-we sort of perspective.

The astronauts' food

When the Man got away for the first time since the cradle of Earth in the early 1960's, many things unknown about the behavior of the human organism in a new environment. Scientists were, with good reason, extremely cautious.
About nutrition, many scientists thought that the Man could not keep anything in his stomach in weightlessness: the feeling reminds continuous free fall, he will make the astronaut constantly vomit!
When Guerman Titov became the first man in space lunched in the summer of 1961, it seemed that most scientists' fears were unfounded.
A basic menu of foods that could be placed in tightly closed containers to prevent fly around in weightlessness.
Of course, at that time there were so many unknown parameters in spaceflight, the many risks and uncertainties involved, the comfort diet rank very low on the priority list.
On the other hand, as the spaceflight evolved and study the behavior of the period progressed, the ration of the astronauts was the subject of detailed design.
What you ate the astronauts had to be planned properly so that doctors would test pilots after the flight they took to their conclusions.

Imagine that you go camping for more than a week with several friends .. You should be sure that you have plenty of food and all the necessary tools for cooking. Food should be stored properly to avoid their destruction. After each meal or at the end of the tour, you will cringe all your equipment and get rid of all the trash before returning home.
The same basic things astronauts do when they are in space. The preparations vary depending on the type of food. Some foods can be eaten in their natural form, such as cookies and fruit. Other foods require water for cooking, such as spaghetti. Of course, there is provided in oven spacecraft and the Space Station to get food at the proper temperature. But there is no fridge in space missions so the food must be stored and prepared properly to avoid lesions, especially on long missions.
Condiments used as ketchup, mustard and mayonnaise. Salt and pepper only exist in liquid form. This is because astronauts can not sprinkle salt and pepper on their food, since they would simply float away from food, thereby creating risks clogging vents, contaminate equipment or get in eyes, mouth or nose an astronaut causing irritation.
Astronauts eat three meals a day, breakfast, lunch and dinner.
Nutritionists assert that their diet is balanced in vitamins and minerals. The caloric requirements differ for astronauts. A woman needs only 1900 calories a day, while a large man about 3200. There is great freedom in the choice of foods such as fruits, nuts, peanut butter, chicken, beef, seafood, pastries, etc. As for the drinks, they drink coffee, tea, lemonade, fruit juice and lemonade.

Now let's go the space !

The Moon's phases

The different shapes, with which emerge the Moon, during its lunar month, called the Moon's phases. The phases are due the illuminated moon's hemisphere the Sun.

The mainly phases of moon are:
1/ New Moon :
It's the phase, the Moon is hard to be seen. Actually, during the days which start the phenomenon of the new Moon, the Sun and the Moon rise and set almost concurrently.
2/ First Quarto :
Seven days and nine hours later, we can see the half part of the Moon, because it shifts eastward. In this phase, the Sun sets, when the moon is in position spuaring and culminates.
3/ Full Moon :
After seven days and nine hours, too, the moon becomes a full tray. During this phase, we are able to admire the phenomenon of full moon, because it is in opposition
4/ Last Quarto :
Seven days and nine hours after the full moon, the moon comes in the last phase. During this phase, the Moon is in squaring and rise at midnight.
