English: The nebula (NGC 6164/6165) surrounding HD 148937 as seen in visible light
Most of the image is taken up by a cloud-like structure shaped like an egg, slightly tilted to the right. It is coloured in shades of orange and pink, with some areas brighter than others. In a gap at its centre, a white sphere shines brightly, with white, blue and green rays coming out of it. Surrounding the cloud are stars of different sizes and colours over a dark background. This image, taken with the VLT Survey Telescope hosted at ESO’s Paranal Observatory, shows the beautiful nebula NGC 6164/6165, also known as the Dragon’s Egg. The nebula is a cloud of gas and dust surrounding a pair of stars called HD 148937. In a new study using ESO data, astronomers have shown that the two stars are unusually different from each other — one appears much younger and, unlike the other, is magnetic. Moreover, the nebula is significantly younger than either star at its heart, and is made up of gases normally found deep within a star and not on the outside. These clues together helped solve the mystery of the HD 148937 system — there were most likely three stars in the system until two of them clashed and merged, creating a new, larger and magnetic star. This violent event also created the spectacular nebula that now surrounds the remaining stars. Credit: ESO/VPHAS+ team.

Der größte Teil des Bildes wird von einer wolkenartigen Struktur eiförmig und leicht nach rechts geneigt eingenommen. Sie ist in Orange- und Rosatönen gefärbt, wobei einige Bereiche heller als andere sind. In einer Lücke in der Mitte leuchtet eine weiße Kugel, von der weiße, blaue und grüne Strahlen ausgehen. Um die Wolke herum sind Sterne unterschiedlicher Größe und Farbe auf dunklem Hintergrund zu sehen. Dieses Bild, aufgenommen mit dem VLT Survey Telescope am Paranal-Observatorium der ESO, zeigt den wunderschönen Nebel NGC 6164/6165, auch bekannt als das Drachenei. Der Nebel besteht aus einer Gas- und Staubwolke, die ein Sternpaar namens HD 148937 umgibt. In einer neuen Studie haben Astronominnen und Astronomen anhand von ESO-Daten gezeigt, dass sich die beiden Sterne auf ungewöhnliche Weise voneinander unterscheiden – der eine erscheint viel jünger und ist im Gegensatz zum anderen magnetisch. Außerdem ist der Nebel deutlich jünger als die beiden Sterne in seinem Inneren und besteht aus Gasen, die normalerweise tief im Inneren eines Sterns und nicht außerhalb zu finden sind. Diese Hinweise trugen dazu bei, das Rätsel des Systems HD 148937 zu lösen: Wahrscheinlich gab es drei Sterne in diesem System, bis zwei von ihnen zusammenstießen und verschmolzen, wodurch ein neuer, größerer und magnetischer Stern entstand. Durch dieses gewaltige Ereignis bildete sich auch der spektakuläre Nebel, der nun die verbleibenden Sterne umgibt. Herkunftsnachweis: ESO/VPHAS+ team.

Esta imagen, obtenida con el VLT Survey Telescope, ubicado en el Observatorio Paranal de ESO, muestra la hermosa nebulosa NGC 6164/6165, también conocida como el Huevo de Dragón. La nebulosa es una nube de gas y polvo que rodea un par de estrellas llamadas HD 148937. En un nuevo estudio que utiliza datos de ESO, un equipo de astrónomos ha demostrado que las dos estrellas son inusualmente diferentes entre sí: una parece mucho más joven y, a diferencia de la otra, es magnética. Además, la nebulosa es significativamente más joven que cualquiera de las estrellas que hay en su centro y está formada por gases que normalmente se encuentran en las profundidades de una estrella, y no en el exterior. Todas estas pistas juntas ayudaron a resolver el misterio del sistema de 148937 HD: lo más probable es que hubiera tres estrellas en el sistema hasta que dos de ellas chocaron y se fusionaron, creando una nueva estrella magnética más grande. Este violento evento también creó la espectacular nebulosa que ahora rodea a las estrellas restantes. Crédito: ESO/VPHAS+ team. Acknowledgement: CASU |
