Beskrivelse
| Beskrivelse |
English: This artist’s impression shows the planet orbiting the star Alpha Centauri B, a member of the triple star system that is the closest to Earth. Alpha Centauri B is the most brilliant object in the sky and the other dazzling object is Alpha Centauri A. Our own Sun is visible to the upper right. The tiny signal of the planet was found with the HARPS spectrograph on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile. In October 2015, astronomers from the University of Oxford published a scientific paper disproving the existence of the planet. They observed that an identical statistical analysis of randomly-generated synthetic data gave the same results as the actual astronomical data.[8] This led Xavier Dumusque, the lead author of the original paper, to concede "We are not 100 percent sure, but probably the planet is not there."
Español: Esta impresión artística muestra al planeta orbitando a la estrella Alfa Centauri B, uno de los miembros del triple sistema estelar más cercano a la Tierra. Alfa Centauri B es el objeto más brillante en el cielo y el otro objeto que resplandece es Alfa Centauri A. La diminuta señal del planeta se encontró con el espectrógrafo HARPS, instalado en el telescopio de 3,6 metros, en el Observatorio La Silla de ESO, en Chile.
Deutsch: Diese künstlerische Darstellung zeigt den Planeten, der den Stern Alpha Centauri B umläuft. Alpha Centauri B ist Teil eines Dreifachsternsystems, deren Mitglieder unsere nächsten Sternnachbarn sind. Alpha Centauri B ist das am hellsten leuchtende Objekt im Bild, das zweithellste ist Alpha Centauri A. Unsere Sonne ist oben rechts als heller Stern ebenfalls erkennbar. Das schwache Signal des Planeten um Alpha Centauri B wurde mit dem HARPS-Spektrografen am 3,6-Meter-Teleskop am La Silla-Observatorium der ESO in Chile nachgewiesen.
Nederlands: Deze artist’s impression toont de planeet die om de ster Alfa Centauri B cirkelt. Deze ster maakt deel uit van een drievoudig stelsel, bestaande uit de meest nabije buursterren van ons zonnestelsel. Alfa Centauri B is het helderste object aan de hemel boven de planeet, Alfa Centauri A is het andere heldere object. Onze eigen zon is rechtsboven te zien. De planeet is ontdekt met de HARPS-spectrograaf van de 3,6-meter telescoop van de ESO-sterrenwacht op La Silla in Chili.
Français : Cette vue d'artiste montre la planète en orbite autour de l'étoile Alpha du Centaure B, un membre du système d'étoiles triple le plus proche de la Terre. Alpha du Centaure B est l'objet le plus brillant dans le ciel et l'autre objet éblouissant est Alpha du Centaure A. Notre propre Soleil est visible en haut à droite. Le faible signal de la planète a été détecté par le spectrographe HARPS sur le télescope de 3.6 mètres de l'Observatoire de La Silla de l'ESO au Chili.
Português: Esta impressão artística mostra o planeta em órbita de Alfa Centauri B, um membro do sistema estelar triplo mais próximo da Terra. Alfa Centauri B é o objeto mais brilhante no céu e o outro objeto ofuscante trata-se de Alfa Centauri A. O nosso próprio Sol pode ser visto em cima à direita. O minúsculo sinal do planeta foi descoberto com o espectrógrafo HARPS montado no telescópio de 3,6 metros no Observatório de La Silla do ESO, no Chile.
中文：这是一张艺术家幻想的半人马座B星及围绕它运动的行星的概念图。半人马座B星是其所在的三星系统中离地球最近的一颗恒星，它与半人马座A星都是夜空中最明亮的星体之一。在这张概念图的右上角还能看到我们的太阳。来自这颗地外行星的微弱信号是由智利拉西拉天文台3.6米口径望远镜的高精度径向速度行星搜索器发现的。 |
