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

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 Search for Extraterrestrial Intelligence.

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?

The National Radio Astronomy Observatory (NRAO) recently disclosed a prototype radio telescope antennae for its next generation Very Large Array (ngVLA) to a group of press, scientists, engineers, and government and business leaders from the United States and Germany at the end of a workshop held at the Max Planck Institute for Mathematics in the Sciences in Leipzig. While construction on the ngVLA isn’t slated to begin until 2026, this recent unveiling provided an opportunity for mtex antenna technology to present its 18-meter dish, which consists of 76 individual aluminum panels arranged in an 8-sided shape.

SETI Researchers can now Scan all Data at the Very Large Array for any Evidence of Alien Transmissions

On February 14th, 2020, the SETI Insitute and the National Radio Astronomy Observatory (NRAO) announced a new partnership, which they appropriately named the Commensal Open-Source Multimode Interferometer Cluster Search for Extraterrestrial Intelligence (COSMIC SETI). This partnership will allow the Karl G. Jansky Very Large Array (VLA) to participate in the Search for Extraterrestrial Intelligence (SETI) for the first time in its history.

In recent weeks, the project took a big step forward with the installation of fiber optic amplifiers and splitters on all VLA antennas, which give COSMIC access to the data streams from the entire VLA. Once this digital backend is online, COSMIC will have access to all data provided by the VLAs 27 radio antennas, which will be able to conduct observations 24/7. In the process, COSMIC SETI will examine around 40 million stars in the Milky Way for possible signs of intelligent life.
