A NASA scientist is coming to Purdue University to discuss the space agency's work on its long-delayed and over-budget successor to the Hubble Space Telescope.

NASA astrophysicist John Mather will give an update on the James Webb Space Telescope during a Thursday afternoon speech at Purdue's Physics Building. He'll also discuss the scientific potential of the telescope, which will peer further into the universe and back in time than ever before.

The telescope is expected to launch in 2018 with an $8 billion price tag following years of delays and cost overruns.

Mather is a senior astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md. He shared the 2006 Nobel Prize in physics with another scientist for their work that helped confirm the Big Bang theory.
