Hubble Space Telescope investigates periphery of striking elliptical galaxy

The NASA Hubble Space Telescope investigated the periphery of striking elliptical galaxy, Centaurus A. The new findings disclose complete details about the most remote portion of an elliptical galaxy. The galaxy has a spiral arms, bright center and swirling. In fact, the galaxy has a dim halo of stars rambling into space.

The scientists portrayed a region of about 4, 50,000 light years across. In addition to the stars' uneven distribution, they displayed surprising properties in relation to the proportion of elements heavier than helium and hydrogen.

It is the halo that has intrigued many researchers. Further, the scientists found that not just the halo of stars extend further from the galaxy's center, however the stars within the halo are also rich in heavy elements.

Laura Greggio, co-author of the new study exclaimed, "The larger stars from it are responsible for manufacturing the heavy elements found in the bulk of the galaxy's stars. Even though the large stars are long dead, the smaller stars of the generation still live on".

By making an examination of the elliptical galaxies, astronomers can actually learn more about the galaxy evolution. The stars in halos of the Milky Way and nearby spiral galaxies are mainly low in heavy statements. If you really consider that the main visible component of the Milky Way is around 1, 20,000 light years in diameter, then the reason behind is large distances.
