Grand Challenge in Astronomy

Bima Consortium Sites

Realtime Astronomy

The grand challenge in radioastronomy is to develop the computational infrastructure necessary to minimize or, better yet, eliminate time delays due to data processing. The overall objective is to develop innovative tools and techniques that permit observation, image formation and data analysis, all of this collaboratively, and in realtime.

In realtime astronomy, astronomers from across the country, even the world could "sit in" on observations, rapidly produce and analyze images and, depending on the results, steer the array accordingly, all of this during a single observing run. Thanks to instantaneous access to computerized archives of run data and associated images, the scientists could continue collaborating in further analysis of the results, sharing their insights as never before, in realtime.

Grand Challenge Goals

None of this will become reality without meeting four crucial objectives.
