Aussie student finds universe's 'missing mass'

SYDNEY, May 27, 2011 (AFP) - - A 22-year-old Australian university student has solved a problem which has puzzled astrophysicists for decades, discovering part of the so-called "missing mass" of the universe during her summer break.

Undergraduate Amelia Fraser-McKelvie made the breakthrough during a holiday internship with a team at Monash University's School of Physics, locating the mystery material within vast structures called "filaments of galaxies".

Monash astrophysicist Dr Kevin Pimbblet explained that scientists had previously detected matter that was present in the early history of the universe but that could not now be located.

"There is missing mass, ordinary mass not dark mass ... It's missing to the present day," Pimbblet told AFP.

"We don't know where it went. Now we do know where it went because that's what Amelia found."

Fraser-McKelvie, an aerospace engineering and science student, was able to confirm after a targeted X-ray search for the mystery mass that it had moved to the "filaments of galaxies", which stretch across enormous expanses of space.

Pimbblet's earlier work had suggested the filaments as a possible location for the "missing" matter, thought to be low in density but high in temperature.

Pimbblet said astrophysicists had known about the "missing" mass for the past two decades, but the technology needed to pinpoint its location had only become available in recent years
