It's the story of a manatee which lives at eagle's house. Or rather, a nebula looking like a manatee which is in the constellation of the Eagle, at 18 000 light-years from the Earth.
This discovery has been done a few days ago by Very Large Array Telescope in San Augustin, New Mexico.

This nebula was formed by the remnant of W50-Supernova, which is 20,000 years old and
which is 700 light-years long. In W50, there's a black hole that devours the gas of a nearby star. This process leads to the formation of a gaseous disk, the Manatee nebula, which causes the appearance of extremely powerful magnetic field. This field expels the electrically charged particles present around W50, and so that forms imposing particle jets propelled at nearly the speed of light (about 300,000 km/s).

Info for astronomy fans : the duo formed by a black hole and a star that feeds him is called a microquasar. The microquasar located in W50-Supernova has been called SS433.

About 2 years without news, Thomas Mars' band come back : Phoenix, a Indie-Pop and Rock band from Versailles (France), known especially for the album Wolfgang Amadeus Phoenix, announces its 5th album by a teaser on their official website (see there).

Bankrupt is the name of this new album. And after viewing this "strange" teaser, which remembers the money machines, we understand that their next songs will be a bit different of what they have done before.

According to a french radio "Virgin", the band will release the album in spring 2013 and will be at the Rock En Seine Festival in August in Paris.

If we want to find the double of the Earth, one of the first things to do is to find a telluric planet with a size similar to our planet. At least 17 billions in the Milky Way : it's the new estimate published by the American Astronomical Society on January 7th based on an analysis of data collected by the Kepler Space Telescope.

And a "sister" of the Earth must be in the habitable zone : it mustn't be neither too cold nor too hot to discover maybe, if the planet is telluric, life at least in the microscopic scale. It's one of the greatest dreams of an astronomer.

But among these 17 billion planets, is there one, two or more like our Earth ? Actually we know zero. But with Kepler Space Telescope, among 2 700 potential exoplanets, 4 planets have a size about 2 times Earth's and are in their own habitable zone.

The Milky Way is so big, too big for us. It's true that we'll don't find all the planets in our galaxy (only 850 found and cataloged), but find a planet with many similarities to the Earth would be a great discovery....

Observing stars and planets, everyone can do that. The birth of a star ? We don't know, but we know how they are born, and that 3-4 stars are born each year in our galaxy. But the birth of a planet ? Now, YES.

Thanks to ALMA radiotelescopes in Atacama desert, Chile, ESO astronomers, whose Simon Casassus, have obeserved the gas supply of a giant gas planet around HD 142527. This star, located at about 450 light-years away from the Earth, is surrounded by a gigantic disc of gas and cosmic dust in two parts, with a huge space between the two parts : the internal has a radius similar to the orbit of Saturn (about 750 M km) and the external 14 times farther.

Probably named HD 142527 b, this planet is one of the first exoplanets (extrasolar planet) discovered in 2013. It is powered by huge gas flows, and so it confirms the theory on the formation of giant planets.


"Astronomers had predicted the existence of these flows, but this is the first time we were able to observe them", said Simon Casassus in a statement from the ESO.


We know that it's very hard to observe directly planets in formation because they are very deep in these gas flows, almost completely opaque. But these flows are studied and so the astronomers will learn more about them.
