E0102-72.3:
Chandra Finds Oxygen Ring in Ashes of Exploded Star
Chandra Image of Oxygen Ring in
E0102-72. This X-ray image of the supernova
remnant E0102-72 shows an expanding multimillion degree
ring of oxygen that was created deep inside a massive
star and hurled into space by the explosion of the
star. The ring is about 30 light years across and
contains more than a billion times the oxygen contained
in the Earth's ocean and atmosphere. Images such as
these provide unprecedented details about the creation
and dispersal of heavy elements necessary to form
planets like Earth. E0102-72 is in the Small Magellanic
Cloud a small galaxy about 200,000 light years from
Earth.
