A homeless planet which floats through space without orbiting a star had been discovered for the first time.
Scientists have speculated on the existence of such a planet and have been trawling the night skies for more than a decade, although the hunt was described as looking for a needle in a thousand haystacks.
The isolated planet, which astronomers believe may have been flung away during its formation, is not tied by gravity to a star and in 100 light years away.
University of Montreal (UdeM) researchers working with European colleagues and data provided by the Canada-France-Hawaii Telescope (CFHT) and the European Southern Observatorys Very Large Telescope (VLT) came across the huge discovery.
Itienne Artigau, an astrophysicist at UdeM, said: Although theorists had established the existence of this type of very cold and young planet, one had never been observed until today.
The absence of a shining star in the area around this planet enabled the team to study its atmosphere in great detail.
This information will in turn enable astronomers to better understand planets that do orbit stars.
Over the past few years, several objects of this type have been identified, but their existence could not be established without scientific confirmation of their age, said Jonathan Gagni, a doctoral student of physics at UdeM.
Astronomers werent sure whether to categorise them as planets or as Brown Dwarfs.
Brown dwarfs are what we could call failed stars, as they never manage to initiate nuclear reactions in their centres.
The planet is called CFBDSIR2149 and appears to be part of a group of very young stars known as the AB Doradus Moving Group.
It is between 50 and 120 million years old, with a temperature of approximately 400 degrees celsius, and weighs four to seven times that of Jupiter.
The studys findings support theories that suggest these kinds of isolated objects are more common than currently believed.
Astrophysicist Ms Artigau, who also worked on the study, said: This object was discovered during a scan that covered the equivalent of 1,000 times the surface of the full moon.
We observed hundreds of millions of stars and planets, but we only found one homeless planet in our neighbourhood.
Now we will be looking for them amongst an astronomical number of sources further afield.
Its like looking for a single needle in amongst thousands of haystacks.
Professor: Reason Itself Is A White Male Construct 2015-07-04 3:55
A philosophy and religion professor at Syracuse University gave an interview to The New York Times Thursday in which he critiqued the notion of pure reason as simply being a “white male Euro-Christian construction.”
Prof. John Caputo was being interviewed by fellow philosophy professor George Yancy for the 13th installment of an interview series Yancy conducts with philosophers regarding racial topics.
Given its emphasis on first principles ...

Jenji Kohan and the Jewish Hyper-Sexualization of Western Culture 2015-07-04 3:33
As detailed in The Culture of Critique, Freud and his followers regarded anti-Semitism was a universal pathology which had its roots in sexual repression. The theoretical basis for this can be found in Freud’s Three Essays on the Theory of Sexuality where he linked aggression to the frustration of human drives — especially the sex drive. Kevin MacDonald notes that: ...

Gays Rights May Open Door for Pedophile Rights 2015-07-03 3:31
Democrats have attempted to normalize pedophilia as a sexual orientation.
A recent Supreme Court ruling on same-sex marriage may soon allow pedophiles to argue they are suffering discrimination.
âUsing the same tactics used by âgayâ rights activists, pedophiles have begun to seek similar status arguing their desire for children is a sexual orientation no different than heterosexual or homosexuals,â writes Jack Minor ...
