 Solar physicist David Hathaway has been watching the Sun every day since 1998, and every day for six years found sunspots. Sunspots are “islands” sized planets, which appear on the surface of the sun are dark, cool, powerfully magnetized, and fleeting: a typical sunspot lasts only a few days or weeks before disappearing. As soon as one disappears, another emerges to take its place.
Even during the period of solar minimum activity, you can see one or two sunspots. But when Hathaway looked on 28 January 2004, there were none. The sun was utterly blank.
And the same happened again last week, twice, 11 and 12 October. There were no sunspots.

The clock is ticking inexorably toward doomsday even if we kill ourselves by poisoning the environment or overheating the planet. As you’ll see, there is one problem with the sun.
The Sun is slowly heating up, as it burns hydrogen in its core. In about five billion years our Sun begins to evolve into a red giant. Its cover foreign gas will expand, engulfing the Earth in the time it reaches its maximum brightness within seven billion years.

The end of the accumulation of nuclear weapons during the Cold War means that the U.S. space agency has enough plutonium for future probes on distant missions, except for a few missions already planned, according to a new study by the National Academy of Sciences United States.
Deep space probes past Jupiter can not use solar energy because they are far from the sun. Thus, its energy supply depends on a particular type of plutonium, plutonium-238. This feeds the spacecraft with the energy released during its natural decay. But the plutonium-238 is not found in nature, is a byproduct of engineering arms.

 The man of the future be a “kind multiplanetaria”, ie residence will have several planets in the universe, and personal portfolio does not live in space for decisions POLICIES. “It is difficult to say Cundo man living on other planets, because it depends on a subject but of a decision Technological Poltica” he said in an interview with Europa Press Argentine engineer and director Institute NASA Space Suits, Pablo De Len.
