SETI, Breakthrough Listen, and Cornell University Search for Extraterrestrial Pulses in GBT Data

Akshay Suresh, a graduate student at Cornell University, spearheads an extraordinary scientific endeavor — a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy. Suresh and his co-authors detail the project’s results thus far in a paper accepted for publication in the Astronomical Journal, “A 4–8 GHz Galactic Center Search for Periodic Technosignatures.”

Peculiar Fast Radio Burst Provides Clues to Mysterious Origin

The Green Bank Telescope was able to observe the directional changes of waves from FRB20190520B as viewed through the lens of a massive star’s atmosphere. Image credit: NSF/GBO/P.Vosteen.

Residing in the heart of a dwarf galaxy four billion light years away is a mysterious cosmological object producing bursts of energy that only last a few milliseconds. New research about this Fast Radio Burst (FRB) has revealed a rarely seen astronomical environment around its source, where magnetic fields twist, turn, and undulate over time. This is the first detection of a magnetic field reversal observed from an FRB, and the first time this behavior has been observed in another galaxy.
