Par La Voix de la Russie | Les explorateurs polaires russes ont commencé à cueillir des particules de la poussière cosmique laissées par la comète ISON en Antarctique. L’expérience est réalisée à la station Vostok, où les experts ont déployé un tissu en polyéthylène ultra-pur de 150 m² pour recueillir ces particules.

La comète ISON a été découverte en septembre 2012. En novembre 2013, lorsque son approche du Soleil, elle a brisé en morceaux. La « queue » d’une partie de la comète, qui continue à se déplacer vers l’étoile, s’approchera la Terre à la fin janvier.

L'étude de la poussière cosmique peut confirmer ou infirmer l'hypothèse d’éventuel transfert de la vie organique par des particules cosmiques.

Mercury becoming visible in January 2014 evening sky









Tonight for January 19, 2014

Mercury, the innermost planet of the solar system, passed behind the sun (as viewed from Earth) on December 29, 2013. That’s when it transitioned from Earth’s morning to evening sky. This evening
– January 19, 2014 – you might be able to catch Mercury in the sunset direction around 45 to 60 minutes after sunset. If you have binoculars, bring them! January 19 marks the beginning
of a time when you might see Mercury in the evening. So if you don’t see it tonight, keep watching the skies after sunset for the rest of this month.


Mercury’s setting time on January 19 depends on where you live worldwide. Mercury sets a bit more than one hour after the sun at mid-northern latitudes. Near the equator, Mercury sets about one
hour after sunset. At temperate latitudes in the Southern Hemisphere, Mercury sets less than one hour after the sun.


An unobstructed horizon in the direction of sunset will be to your advantage for finding Mercury. Presently, this world is almost as brilliant as the star Sirius, the brightest star of the
nighttime sky. The evening twilight will obscure the planet’s luster, but you’ll be surprised at how bright Mercury can appear. If you can’t see Mercury with the eye alone, you might be looking
too soon after sunset. Or there might be thin clouds in the direction to your horizon. Try your luck with binoculars. If still no luck, try again tomorrow.


Not too late. Order your 2014 EarthSky Lunar Calendar today!

From mid-northern latitudes and farther north, you can use the Summer Triangle to confirm your identification of Mercury, the innermost planet of the solar system.



Don’t give up if you don’t spot Mercury this evening. Day by day throughout January 2014, Mercury will climb farther away from the sunset glare and will set later after the sun. By the month’s
end, Mercury will set over one and one-half hours after the sun at mid-northern latitudes.


Mercury wins superlatives for being the solar system planet with the shortest year – yet the longest day. In fact, a day on Mercury lasts twice as long as its year. On Mercury, one day equals 176
Earth-days while one year is only half that long: 88 Earth-days.


Bottom line: On these late January 2014 evenings, look for the planet Mercury to pop out over the sunset point on the horizon as dusk is ebbing toward darkness. By the month’s end, Mercury will
set over one and one-half hours after the sun at mid-northern latitudes. Good luck!

C'était donc bien Mercure sur Lasco C3. Merci.
