Between Galaxies Lonely Supernovae

Clusters of galaxies and the space is not completely empty - may be stars. The intracluster stars in their host galaxies have been left to experience rather than as energy and space galaxy alone. Although they have isolated them and containing the universe, is still important to understand how these people where mass.

However, there is a catch fish. It is relatively nearby stars out to Andromeda, but it can, it is not easy to see the stars in our local universe beyond a single person. More galaxies astronomers mapped the normal matter, the situation in many bright and easy to identify the supernova, because it has turned.

A few years ago, Canada France Hawaii Telescope (CFHT) the researchers used a distant galaxy clusters in and near the type IA supernovas of the survey was carried out. They clearly have enough explosions "and then galaxies could solve many of your images to ensure the exploding white dwarf discovered four floating in empty space, but. Now, the Hubble Space Telescope, Melissa Graham (California, Berkeley University) and colleagues have evidence using images of hand.

The authors also confirmed the isolated nature of the CFHT three supernovas - seems to dwarf galaxy the fourth odal. Graham and her colleagues, they found 11% of all supernova occurred galaxy space calculation. That we can not see the stars, gas, and dust and heavier elements in trace average, approximately 11% from the normal matter and that galaxy floating space.

Researchers hope to use the better galaxy of stars to understand the formation of clusters, intracluster. The stars' light years away more than 300 neighbors each (70 times longer our nearest neighbor, Proxima Centauri more) may even lie, intracluster is gravitationally bound cluster of stars of the galaxy as a whole. Think like a hermit living in a cave next to the big city; City residents will not interact with the hermit, but she is still a large part of society. Like a hermit, intracluster stars, galaxies can obtain knowledge about the history of their inter exilers.
