Alien hunters turn to IBM and big data tool in hunt for ET

29/10/2015 by Sharon Shahzad


Looking for extra-terrestrial life is not usually associated with big data analytics and IBM technology, and is usually left to enthusiastic stargazers and people who may have been in the Mojave desert for too long.

But the SETI (Search for Extra-Terrestrial Intelligence) Institute begs to differ. SETI was showcased as an IBM customer at the company's Insight 2015 conference in Las Vegas, and makes use of IBM's Cloud Data Services and Apache Spark to analyse huge amounts of data harvested from the Allen Telescope Array in California.

SETI's goal is to find obvious narrow-band aspects of radio signals that differ from background astrophysical and human signals.

Dr Jill Tarter, holder of the Bernard Oliver Chair at SETI, said that four years of listening to signals has resulted in a collection of 100 million signals and a vast amount of raw data on the frequencies to which they relate.

This has given SETI a large database of signals that it has identified as interference from humans and non-alien sources.

SETI uses a combination of analytical resources in IBM's Cloud Data Services portfolio and Apache Spark to query this data and determine whether SETI may have missed something in the recorded interference.

The institute also uses this combination of cloud-based analytics and in-memory framework to find faster ways to diagnose signals.

With a vast number of companies moving some, if not all, of their operations to the cloud, security continues to be of major concern. Whilst there are numerous patches and firewalls to safeguard defences, it has been highlighted that the most difficult area to protect against is human interaction.

The oil and gas industry has had a notoriously challenging time of late, with the prices of oil plummeting and causing many firms to tighten their belts. However, offshore exploration is providing a much-needed bright spot for the sector, with an increasing number of governments becoming more accommodating. In the past week, it has been revealed that there are big changes afoot for Brazil’s petroleum laws. Shell has already begun to move on this opportu...
