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.
The picture, which was
taken with the Wide Field Imager (WFI) at ESO's La Silla Observatory in
northern Chile, allows seeing many stars that formed about 10,000 million years
and have already become old asteroids red giants.
However, the cluster
also houses most luminous blue stars and apparently younger, that should have
been off with his companions.
Astronomers have
studied this phenomenon for years, managing two theories: they are stars that
are formed by collision and fusion between them or that are created from a
transfer of material between two companion stars.
Both approaches share
the basic idea that these apparently younger stars were born not as large as
seen today, but received an injection of extra material sometime life handed
them.
The European Southern
Observatory is an intergovernmental organization consisting of 14 European
countries and Brazil, and Chile operates two observatories at Cerro Paranal and
Chajnantor.
