How many planets are there in our galaxy? That's a tricky question to answerAre there other planets that support life? That’s exactly what the Kelper mission hopes to discover.1) NASA launched the Kelper space telescope, designed to find habitable planets, in 2009. So far it has discovered 2) five new Earth-sized planets beyond our solar system. These planets are hotter than the Earth’s sun - much too hot for life as we know it. The Kelper team predict that 3) they will need at least three years (and possibly longer) to find an Earth-like planet. The simplest requirement for a planet to have life (carbon-based life like on Earth) is for there to be liquid water (not frozen or gas) so the distance from the planet’s sun and therefore temperature are important. There also needs to be the correct amount of air. If a planet is as small as 4) Mars (half the size of Earth) its weak gravity means that it can’t hold on to air molecules. If a planet is 5) Neptune sized (four times bigger than Earth) it has very strong gravity and too much air. So size matters too.A)
2009 - This is the year when NASA launched the Kelper space telescope, designed to find habitable planets.
5 - five new Earth-sized planets beyond our solar system
3 - they will need at least three years (and possibly longer) to find an Earth-like planet.
¹/₂ - Mars is as smallas half the size of Earth
4 - Neptune is sized four times bigger than Earth
600000000 & is the cost of the mission
2013 - it is scheduled to observe

In ours days we are all dependent on the phone. Some believe that it is bad and the other good.Pros gadgets that we can communicate with people in the far distance. Watch movies, read books and listen to music. Get any information at any time. Whether it is early in the morning or late at night.In addition, there are pluses and minuses. For example, the deterioration of view, a waste of time. It may also lead to dependency.Personally, I need a phone in order to receive new information, listen to music, take photos and video that will remind me wonderful moments of my life. Watch movies, read books. I think all you need to use all possible technologies correctly and not abused.
