Gravitationally lensed supernova provides insight into dark matter distribution

[gary]

An article by Bridie Smith, Science Editor for The Age, discusses
the discovery of a type 1a supernova that has been gravitationally
lensed.

The discovery was made whilst searching Hubble Space
Telescope imagery and the discoverers have written a paper that
appears in Science.

Since the same supernova can be seen multiple times at multiple
points in time, it is presenting astronomers with a rare opportunity
to study the distribution of dark matter in the universe.
