New Astronomy Project Seeks 'Buried Treasure' in Huge Databases

A new research group aims to make a big dent in the backlog of astronomical data currently sitting in online archives around the world, just waiting to be analyzed.

The group — which is known as Astroinformatics and is based at the Heidelberg Institute for Theoretical Studies (HITS) in Germany — hopes to develop methods that will make searching huge and ever-growing astronomical databases easier and more intuitive.

"The amount of data increases exponentially," group leader Kai Polsterer said in a statement. "The number of astronomers does not."

NASA's Kepler space telescope is another data hoarder. Over its four years of observation, Kepler eyed more than 150,000 stars continuously, hunting for signs of orbiting planets. It will take years for scientists to sift through all of the spacecraft's observations. (Indeed, although the telescope's planet hunt ended this past May, researchers are continuing to announce new finds using Kepler data.)

Astroinformatics hopes to make sorting through this massive influx of information easier. The program will automatically calculate features about a celestial object from the data, such as its redshift — a measure of how much the expansion of space has stretched an object's light to longer wavelengths, which in turn can reveal its distance.

"We focus on using new approaches to support observing scientists with their research," Polsterer said.

"There are many treasure chests full of data to be unearthed," Polsterer said.
