Découverte d’une nouvelle planète avec quatre soleils

Du jamais vu. Jusqu’à présent, aucune planète n’était illuminée par plus de deux soleils. Une nouvelle vient d’être découverte par des astronomes américains. Elle est en orbite dans un système stellaire quadruple. Son nom : PH 1.

PH1 est une nouvelle planète. Elle vient d’être découverte par des astronomes américains. Elle fait six fois la taille de la Terre et est illuminée par quatre soleils. C’est le premier système stellaire de ce type observé jusqu’à présent.
PH1 est en orbite autour de deux soleils, et deux étoiles tournent autour de ces derniers. C’est un système stellaire quadruple. La planète est située à 5.000 années lumières de la Terre (soit, 47.305.000 milliards de kilomètres). “La découverte de tels systèmes stellaires nous force à repenser comment ces planètes peuvent se former et évoluer dans un tel environnement” relève Meg Schwamb, principal auteur de cette recherche et chercheur à l’université de Yale.
PH1 est la première découverte du programme, crée en 2010, Planet Hunters qui encourage les astronomes amateurs à identifier les planètes qui se situent en dehors de notre système solaire, grâce au télescope spatial américain Kepler.
Cette découverte a été mise en ligne sur le site arxiv.org et a été soumise pour publication dans l’Astrophysical Journal.
PH1 is born! Amazing dicovery by the Planet Hunters telescope called Kepler. 5000 light years away, or 47,305,000 billion kms, this research at Yale university will force astro-physisists to re-think the evolution of the universe. Given the name PH1 this planet is six times the size of earth and is absolutely unique as it is illuminated by four Suns (first planet ever discovered with more than two suns) and is in an orbit with four stars.
So the magnificent universe continues to divulge fantastic secrets in its ever expanding development while at the same time expanding our knowledge 13.7 billion years after the big bang. C’est magnifique, fait par les mains de notre Dieu.
About bill
Worked in the technical / engineering area as a Science Laboratory Technician and as an Aeronautics Engineer.
The artistic side involves writing under the nom de plume of Billy Olsenn, his recently written play 'A Case of Wine' was staged by the players group Straight Make-Up at the 2012 Birr one act drama festival. It's next staging was in the one act circuit is in Cavan, at Maudebawn on Sat 10 Nov 2012. Then it was performed in the Bray, Co.Wicklow at the very popular one act festival in January 2013.
Next play is FEAR. A dark tale about revenge on the cruel death of two pensioners by young thugs. Neighbours hatch a devious and dangerous plan to exact old-style revenge. Bill is a member of the Drama League of Ireland and his plays have been critically vetted and certified as original pieces of work by the DLI.
Another literary project is that of commemoration of an aircraft crash on Djouce mountain in Wicklow in 1946. Bill wrote articles for the 50th, 60th and most recently the 70th anniversary, (12 Aug
2016) all were published in the Wicklow Times and ensured the survivors of the crash, all French Girl Guides, were not forgotten. Articles reproduced on this website.
But mostly this site gives a more general European and specific French slant on popular and not so popular articles of French news, translated to English by the author. Each article is translated on a paragraph by paragraph basis so easy to read in either language and even possible to improve either language by comparison of the short English and French paragraphs. Amusez vous bien.
The author is currently writing an easy to read technical aviation book centered around the Fokker 50.
Another interest is that dealt with in another of Bill's websites www.realnamara.net, a Statue of the mother of God, Mary. It was erected in 1972 in Dublin, at the end of the Bull Wall near Clontarf, and my grandfather William Nelson, was the main instigator of that project. I give talks on the history of the statue and my grandfather's adventurous and dangerous life at sea.
Technical assistance with each website is by J O'N.
