Found, 32 New Planets Outside Solar System

One year ago, European scientists announced the discovery of astronomy 32 new planets outside the solar system. According to news agency Associated Press, The findings strengthen the evidence of the theory that the universe actually has a lot of places to build a life.

Using telescopes from the European Southern Observatory, the researchers revealed that the planets they found not the same size with the earth. They figured if the planets were habitable. However, research results that increase the number of planets found outside our solar system, that is counted more than 400 pieces.

Six of the new planets discovered sized several times larger than Earth, which is believed to contain habitat for more than 30 percent of the capacity of the Earth. Most of the planets found there the same size bigger than Jupiter.

While two of the new planets discovered there is a size five times smaller than Earth’s, except that there are five times bigger than Jupiter.

Astronomer Stephane Udry of the University of Geneva revealed that the findings support the theory that planet formation is generally the same, especially with a view of star formations.

“I am quite sure that much like Earth-sized planets,” Udry said in a conference in Portugal. “Nature does not have a vacuum. If there is space, then there is a planet,” said Udry.

Astronomy experts also stated that about 40 percent of stars like the sun has a number of planets whose size is closer to Earth than Jupiter. Jupiter’s mass 300 times greater than Earth’s mass.

Found, Maya Advanced Water Canal

The team of researchers from the United States had just found a canal or drainage work in the Maya city of Palenque, Mexico, which is the first engineering samples of water pressure in the world.

The team of researchers from the University of Pennsylvania is an archaeologist and expert hydrology. They found evidence of how the Maya used the water channel that is regulated by pressure, but details are still unknown process.

“The system water pressure was thought to be introduced by the Spaniards when his arrival,” said researchers in the Journal of Archaeological Science latest edition. But now there is new evidence that older.

Based on archeological data, seasonal climatic conditions, geomorphology shape, and hydraulic theory clearly indicates that the Mayas in Palenque Chiapas have applied empirical knowledge of the channel closed pressurized water before the presence of European nations.

The technology was first identified in 1999 when the survey mapping. While the water channel that flows beneath the city region is unknown. Then in 2006, an archaeologist back to Palenque with hydrology experts to examine the unusual water features.

Palenque area was first inhabited in the year 100 AD, but grow larger when the Mayan classic period took place, namely the year 250 until 600 AD. The city was abandoned around 800 AD.

“Under natural conditions it was difficult to imagine the Maya made regular samples of water pressure in their world,” says Christopher Duffy, professor of civil and environmental engineering.

Underground water channels as akuaduk not common in Palenque because the Mayan city built in a small area on top of a long cliff. To make available land habitable, the Maya at Palenque create a channel route under the city through akuaduk.

“They create a space city,” said Kirk French, professor of anthropology. “There is a channel in the area every 300 feet or across the cliff. Very little land that can be built.”

Channel is also useful in the rainy season so that the danger of flooding can be anticipated and controlled at least partially drained. Channel studied by experts named akuaduk Piedras Bolas located above ground are steep with a height of 20 feet.
