SETI Researchers Double-Checked 1 Million Objects for Signs of Alien Signals

<p>We can’t help ourselves but wonder about life elsewhere in the Universe. Any hint of a biosignature or even a faint, technosignature-like event wrests our attention away from our tumultuous daily affairs. In 1984, our wistful quest took concrete form as SETI, the <a href="https://en.wikipedia.org/wiki/SETI_Institute">Search for Extraterrestrial Intelligence</a>. </p>

<p>Unfortunately, or maybe fortunately, SETI has turned up nothing. Recently, scientists used a powerful new data system to re-examine data from one million cosmic objects and still came up empty-handed. Did they learn anything from this attempt?</p>

<p>This effort used COSMIC<span style="margin: 0px; padding: 0px;">, which stands for <a href="https://www.seti.org/cosmic" target="_blank">Commensal Open-Source Multimode Interferometer Cluster</a>. It’s a signal-processing and algorithm system attached to the Karl G. Jansky <a href="https://en.wikipedia.org/wiki/Very_Large_Array" target="_blank">Very Large Array</a> (VLA) radio astronomy observatory. According to SETI, it’s designed to “search for signals throughout the Galaxy consistent with our understanding of artificial radio emissions. “</span> </p>

<p>Modern astronomy generates vast volumes of data and algorithms and automated processing are needed to comb through it all. So far, COSMIC has observed more than 950,000 objects, and the results of the effort are in a new paper. It’

Okay. You caught me. Youtube is teaching me about #RadioInterferometry https://youtu.be/biB4WpXQtrg?feature=shared

(boosting appreciated) The deadline for the postdoc opening described below has been extended to September 30th, 2024.

We have one postdoc opening in my research group, the Image and Signal Processing Group (ISPGroup), Applied Mathematics department, UCLouvain, Belgium, to work on the QuadSense project, a new project funded by the Belgian Fund for Scientific Research - FNRS. Topics: #InverseProblem #RankOneProjection #Imaging #RadioInterferometry #ComputationalSensing More information about this project and conditions:
