Le Poids du Réel

une 24—Looking like a big red eye in the sky, this latest image from the Hubble Space Telescope is giving astronomers the clearest glimpse yet into one of our nearest celestial neighbors. The heavenly halo captured by Hubble is actually a cloud of gas and dust particles surrounding the small star Fomalhaut. The star, which from Earth can only be seen in the Southern Hemisphere, is 25 light years from our solar system—that's just around the corner in astronomical terms.

NASA astronomers unveiled the image June 22, describing it as the most detailed picture ever taken of the nearby star using visible light. The cloud's distinctive cat's-eye shape, astronomers said, is evidence that at least one small planet is orbiting Fomalhaut. Though it can't be seen in the picture, researchers suspect the planet is there because of its gravitational calling card: The oval shape and sharp inner edge of Fomalhaut's halo are signs that a planet is "sweeping" through the dust and gas.

The astronomers were quick to credit Hubble and what they called its "exquisite optical resolution" for the discovery. "This observation is currently impossible to do at visible wavelengths without the Hubble Space Telescope," astronomer Mark Clampin of NASA's Goddard Space Flight Center said in a statement. "The fact that we were able to detect it with Hubble was unexpected, but impressive."

Si le Réel c'est l'Imposible la personne handicapée est confrontée à cet impossible.

Impossible de marcher bien sûr mais la liste des impossibles est si longue qu'elle se résume à l' impossibilité de vivre sa liberté d'aliénation......

Beaucoup de discours autour du handicap...

...Pour une assignation à une place:

Mais comme il est dit dans le film Nationale 7 pourtant si saturé de clichés, le handicap majeur de l'homme est ailleurs:

June 6, 2006—Our solar system could have its own "mini-me" floating in the vast reaches of space.

That's the theory being proposed by a team led by a University of Toronto astronomer, whose latest research reveals that planetary nurseries could exist not only around stars, but also around planet-size objects about a hundred times less massive than our sun.

The work focused on newly formed planetary mass objects, or planemos—objects with about the same masses as planets that do not orbit stars—as envisioned by this artist's conception.

Young planemos are similar to stars in that they are still very hot from the energy it takes to form and are surrounded by disks of debris. The disks contain the raw materials for planet-making, suggesting to scientists that miniature versions of the solar system could orbit planemos that are not much larger than Jupiter.

The finding complements previous research showing a potentially planet-forming disk around a brown dwarf—a star that didn't grow large enough to ignite. (Read "'Diamond Planets' Hint at Dazzling Promise of Other Worlds.")

But the researchers note that as planemos age and cool, prospects for life on the objects' tiny progeny would be dim.

Without the heat radiated by a fully formed star, "any kind of planet that forms around them is committed to an eternal freeze," lead author Ray Jayawardhana told the Reuters news agency.
