How one galaxy can be a cluster

Article Abstract:

Scientists Hattori et al have identified a distant cluster of galaxies in space sector MG2016+112 using X-ray emission detection techniques but have not taken any realistic measurement of space density at the site. Further research is necessary to identify a rich cluster of lower magnitude limits. The x-ray image of massive galaxy cluster MG2016 is shown.

Article Abstract:

HE0107-5240 and HE1327-2326 are the two metal deficient stars discovered by the astrophysicists in 2002 and 2005 respectively. HE1327-2326 has an iron abundance about half that of HE0107-5240 and these stars are found to be of great significance to the astrophysicists.
