New View of the globular cluster 47 Tucanae

Globular clusters 47 Tucanae are huge spherical cloud of old stars held together by gravity. They are turning around the cores of galaxies, and satellites orbiting Earth. These groups of stars contain very little gas and dust - it is believed that most of the cluster has been driven by winds and explosions of stars it contains, or has been torn by the interstellar gas has been interacting with the cluster. Any remaining material coalesced into stars billions of years ago.

Stars young and old?

This colorful view of the globular cluster NGC 6362 has been with the Wide Field Imager on the ESO / MPG 2.2-meter telescope was added to the ESO La Silla Observatory in Chile. Together with a new recording of the central region of the cluster, which has delivered the Hubble Space Telescope by NASA and ESA, this picture conveys the best to date view of this little-known globular cluster. The majority of stars in globular clusters is very old. In this bunch there are also some stars that act unusually young.

A new image of NGC 6362 star field

The European Southern Observatory (ESO) today released a new image of the globular cluster NGC 6362; a little known field stars located in the group of Ara consists of tens of thousands of stars very old and others looking surprisingly young.

Globular clusters show: how galaxies come in several waves

The origin of most galaxies is not uniform, but run in several stages. This is a study of over 900 globular clusters by an international research team. The star clusters from the dawn of galaxy formation to occur mostly in two different chemical variants, the astronomers reported in the journal "Monthly Notices of the Royal Astronomical Society".

"This indicates presence of two types of globular clusters suggest that most large galaxies have gone through two phases of star formation through", Christopher Usher of the Swinburne University of Technology in Australia write Hawthorn and his colleagues.
