Astronomers Discover 3 Planets That May Support Life

Astronomers Discover 3 Planets That May Support LifeAstronomers announced that they’ve identified a star system with up to seven planets — three of which could potentially host life — 22 light-years away.

‘Habitable zone’

The likelihood that conditions could support life on at least one of those planets, given that there are three terrestrial-mass planets in the habitable zone of one system, is “tremendous,” according to at least one scientist. The “habitable zone” is the area near a star in which a planet can theoretically hold liquid water. In our own solar system, Venus is close to the inner edge of potential habitability, while Mars is closer to the outer edge.

The discovery is the largest number of “habitable zone” planets ever found within a single system, said Guillem Anglada-Escude of the University of Gottingen, Germany, who led the team of astronomers. The findings were published Wednesday in the journal Astronomy & Astrophysics. The findings are only the latest in a recent string of identifications of planets that may host life.


‘More exciting discoveries’

The three planets orbit a star called Gliese 667C, part of the triple-star system Gliese 667. They are between four and eight times the mass of the Earth, making them “super-Earths.” The planets are likely either rocky or water worlds, meaning they’re entirely covered in water. These particular planets also appear to be “tidally locked,” meaning the same side of a planet is always facing a star. That means one side of the planet always gets light and the other hemisphere is always in darkness.

Because they are so far away, the composition of the atmospheres of all of these planets outside our solar system remains unknown. Whether life truly roams or swims out there is still to be seen. Still, Anglada-Escude says the existence of star systems packed with potentially habitable planets, and the diversity of planets that Kepler has found, suggest there are more exciting discoveries yet to come.

Do you think the astronomers are very close to finding another planet that is truly habitable for us? Feel free to share your speculations with us!

Chris Matthews: Romney Challenging Obama Is Unconstitutional

Chris Matthews Romney Challenging Obama Is UnconstitutionalThis week, MSNBC “star” Chris Matthews made the following statement, clearly speaking out of frustration as he watched President Obama wilt under the scrutiny of the second presidential debates where he was challenged repeatedly by Republican Mitt Romney: “I don’t think he understands the Constitution of the United States…He’s the president of the United States. You don’t say, ‘you’ll get your chance.’”

‘Above the people’

Chris Matthews was angry with Romney challenging the president on his record during the course of an election to unseat him. You would think Matthews would know what is in the Constitution and what is not. Nowhere in the Constitution does it set forth that a president of the United States is above the people and cannot and should not be challenged. Is that not what a presidential election is all about – challenging an incumbent president on his record?


‘Preserve, protect and defend the Constitution’

The Founding Fathers specifically limited the powers of the president and did not exempt a president from abiding by the laws of the land in the same manner and to the same extent as the average citizen. The president of the United States in the Oath of Office swears to the following:

“I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States.”

I have news for Matthews: there is no greater responsibility a president has than to preserve, protect and defend the Constitutional protection of a citizens’ freedom of speech — presidents are neither immune from it nor protected from it.

How about you — what is your opinion about Mitt Romney challenging President Barack Obama? To which candidate are you casting your vote for?
