Why “Big Data” Is a Big Deal Information science promises to change the world

March 1, 2014

Goodman uses visualization as an exploratory technique in her efforts to understand interstellar gas—the stuff of which stars are born. “The data volume is not a concern,” she says; even though a big telescope can capture a petabyte of data in a night, astronomers have a long history of dealing with large quantities of data. The trick, she says, is making sense of it all. Data visualizations can lead to new insights, she says, because “humans are much better at pattern recognition” than computers. In a recent presentation, she showed how a three-dimensional visualization...

Historical data: Hidden in the past

September 22, 2017

Attitudes towards archived data have changed in other fields, too. Astronomers used to look down on colleagues who analysed old data, says Alyssa Goodman, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. They were seen as “some sort of second-rate scientist who couldn't get telescope time”, says Goodman, who is also the founder of Astronomy Rewind, a citizen-science project to gather information from astronomy-journal images dating to the mid-1800s. “That is what has completely changed,” she says — astroinformatics, a field that involves analysing previously gathered data, has emerged in the astronomy community....
