|Jay Gabany: the best of America||Émilie Martin
|The American Jay Gabany is regarded as one of the
best astrophotographes current amateurs. Small selection of its
the most impressive stereotyped.
|Two black holes in collision: How they make vibrate the
|They are two Titans! Two monsters whose total mass
reaches 150 million times that of the Sun... Irremediably
involved one towards the other, the two giant black holes observed
near the Milky Way will end up amalgamating in an impressive cosmic
|Document: Flashes at the borders of space||Muriel Valin
|Fantastic flashes illuminate the upper atmosphere
regularly. By studying them, the scientists are discovering that
they generate formidable energies. As for their origin, it
remains still quite mysterious.
|A cosmic string put in examination||Myriam Détruy
|The assumption of the cosmic strings, these negligible
cracks of the Universe appeared at the time of the Big-bang, always
awaits its proof by the observation. Until January, a team
believed to see in the image of two twin galaxies this so much hoped
confirmation. So much so that they had recourse to the Hubble
telescope to slice.
|The water of the Earth fell from the sky||Émilie Martin
|It from now on is proven: water was brought on
Earth by the asteroids! Emitted for more than ten years, this
assumption has been just confirmed by the detection of an ejecting
group of asteroids of the steam. The true history of blue planet
finds its source... in space.
|Extraterrestrial life: What it is necessary to seek||David Fossé
|In fifteen years the space telescopes able will be
launched to unearth life on planets identified today around other
stars. But how the astronomers have will the proof that they
hold finally an alive world? Which signs will undoubtedly state
to them that vegetable or animal species developed over there?
The space agencies currently decide instruments which will have
to be embarked on the telescopes Darwin and Terrestrial Planet Finder
to collect these invaluable indices of a life elsewhere in the
|Cubic Ice: A telescope cut in the ice||Philippe Henarejos, Lucia Simion
|Hunting for the cosmic neutrinos takes a new dimension
with the South Pole Since more than one year, a gigantic detector of
one kilometer cubic takes form in the icecap of the Antarctic. A
technical and human challenge which should open a new window on the
Universe from here 2011.
|Broken down comet amateurs||David Fossé
|It is an astonishing paradox: whereas in ten
years, the number of comets discovered was multiplied by thirty, the
astronomers amateurs discover only two as well as possible of them per
annum! How does one discover a comet and why is this much more
difficult than formerly? Inquire into a community of which the
ambition remains to hang names with the firmament.
|Great exposure in Clermont-Ferrand: All on the Sun||Myriam Détruy
|During all the summer and until the end of the autumn,
the Sun is in the high-speed motorboat in Clermont-Ferrand in a free
exposure of a great originality which had already been noticed in 2004
|Saint Martin's day de Queyrières: The observatory which
returns by far||Myriam Détruy
|Saint Martin's day de Queyrières, the tenacity of an
impassioned man of stars, Herve Derycker, allowed ressusciter the
observatory of Briançon them Écrins, which had in particular taken
the lightning. Today, of its headland, the new observatory
proudly looks at a preserved sky of the urban gleams.

|Rare phenomenon: March and Saturn spend this
month in front of the Crib, one of the most beautiful star clusters of
|Drive out Mercure in the twilight||Emmanuel Beaudoin
|Voir Mercure is an event. The planet nearest to
the Sun is so discrete that many amateurs never observed it.
This month, it passes in favorable position in the sky of the
evening. An occasion not to fail to discover this planet
perpetually masked in dazzling solar halation.
