Hollow galaxies New research shows that the center of the Milky way lacks young stars-hamimelon

Hollow galaxies? A new study shows that the Milky Way Galaxy lacks a young stellar Galaxy? Astronomers have found that, except for a small number of stars, there is a clear lack of young stars in the space near the center of the Milky way galaxy. The picture shows the art exhibition, distribution of Cepheids in the Milky Way system, you can clearly see the space near the center of the Milky Way in stars hollow phenomenon galaxy’s core strange very dense, spreading but large clouds of dust and gas there will seriously block the light, so that they are difficult to be observed. We are in the position of the sun position is outside the Milky Way department in the Milky Way department one of the spiral arms of Sina Technology News Beijing on September 2nd news, according to the British "Daily Mail" reported, according to a new study, we from the centre of the Milky Way looks more like a star home, rather than stellar nursery. Astronomers’ observations of the center of the Milky way show that there is a serious shortage of young stars in the vast space. Prior to this, astronomers once in the core area of the Milky Way Department observed young stars, but most of the new research also confirmed a vast region of space, the apparent lack of presence of young stars. The researchers believe that the findings are contrary to the previous view that the near core region of the galaxy should have a new star region, and that further research could change our understanding of the Milky way. The core of the galaxy of stars is very dense, spreading but large clouds of dust and gas there will seriously block the light, so that they are difficult to be observed. Our sun is located in the outer part of the Milky Way galaxy, on one of the spiral arms of the Milky way. Although far away from the center of the Milky Way, but astronomers can still observe the center of the Milky Way system using a variety of methods, such as the use of a class called "unique star Cepheid, astronomers can determine the Milky Way line between each part very smoothly in the distance. There is a relationship between the cycle and the actual luminosity change Cepheid light, astronomers can be used to directly determine the distance in space, so they are astronomers affectionately known as "standard candles". Although this method is generally used for the determination of the distance between galaxies at a very large scale, astronomers can also use it to measure the distance of stars near us. Schematic diagram of the Milky Way Department: survey of the newly discovered Cepheids are marked with yellow, and had already know the point in white point, the sun said with a red sign. The middle of the range in green is the research scientists found, located in the center of the Milky Way line "Cepheid desert" recently, an international team from Japan, South Africa and Italy astronomers carried out on the composition of the Cepheids in search of work, the star’s age are generally not more than 300 million in about 4 billion 500 million years compared to the sun much younger. In the search process, they noticed an unexpected situation, when they swept through the central region of the Milky way, it was almost a desert star. In the Milky Way line near the center, except for a small number of Cepheids, there)相关的主题文章:
