#6405

I’ve gotten tired of chasing you. It seems like every time you see me doing fine you wanna butt your head in my business. No more. If you cut me off every time I try. It’s time to call it’s quits. Go to hell dg.

The Butterfly Cluster

To some, the outline of the open cluster of stars M6 resembles a butterfly. M6, also known as NGC 6405, spans about 20 light-years and lies about 2,000 light years distant. M6 can best be seen in a dark sky with binoculars towards the constellation of Scorpius, coving about as much of the sky as the full moon. Like other open clusters, M6 is composed predominantly of young blue stars, although the brightest star is nearly orange. M6 is estimated to be about 100 million years old. Determining the distance to clusters like M6 helps astronomers calibrate the distance scale of the universe.

The Butterfly Cluster (cataloged as Messier 6 or M6, and as NGC 6405) is an open cluster of stars in the constellation of Scorpius. Its name derives from the vague resemblance of its shape to a butterfly.

The first astronomer to record the Butterfly Cluster’s existence was Giovanni Battista Hodierna in 1654. However, Robert Burnham, Jr has proposed that the 1st century astronomer Ptolemy may have seen it with the naked eye while observing its neighbor the Ptolemy Cluster (M7). Charles Messier cataloged the cluster as M6 in 1764. It was not till the 20th century that star counts, distance, and other properties were measured.

M6: скопление Ба

M6: скопление Бабочка.

Некоторым наблюдателям форма этого рассеянного звёздного скопления напоминает бабочку. Скопление M6, также известное как NGC 6405, расположено на расстоянии 2&остирается на 20 световых лет. M6, изображённое на этой изображения, можно увидеть на тёмном небе с помощью небольшого телескопа в направлении на созвездие Скорпиона. На небе скопление занимает область размером с полную Луну. Как и прочие рассеянные скопления, M6 состоит преимущественно из молодых голубых звезд, хотя ярчайшая звезда оранжевого цвета. Считается, что возраст M6 составляет 100 миллионов лет. Определяя расстояние до этого скопления, исследователи калибруют шкалу расстояний во Вселенной.
