Making synthetic technosignatures to aid radio SETI searches

In the search for extraterrestrial intelligence (SETI), we are fundamentally looking for signals that have never been detected before. That said, in radio SETI, we do make the assumption that intelligent civilizations emit

Searching for Technosignatures in TESS Targets that Transit During Observation

Ideally, in the search for extraterrestrial intelligence (SETI), we would want to observe every object in the night sky at all times over all frequencies. Yet, as should be obvious, this multidimensional observing

Connecting the dots with optical SETI workshop

My name is John Hoang, postdoctoral scholar working at the Berkeley SETI Research Center (BSRC). With help from the team, I recently organized a 2-day workshop to inform the community about several current

Interstellar Societies: Possibility or Improbability?

The future of interstellar travel may be the most important factor when considering SETI strategy. Are societies spanning entire galaxies, with billions of inhabited worlds, likely to exist? Are they even possible? Two

Radio Observations of Transiting Exoplanet Systems

As we attempt to answer the question, “are we alone in the universe?”, there are many places to search. Although life might not necessarily arise in environments similar to Earth, Earth-like exoplanets are

SETI Target Selection for MeerKAT

New approaches in the development of radio telescope arrays enable multiple users to receive and process data simultaneously. This architecture presents unique opportunities to conduct commensal ("piggyback") SETI surveys alongside primary

Life in Elliptical Galaxies

What happens on galactic scales seems far removed from life on Earth. Galactic habitability is the idea that the cosmic environment of a planet can influence — or inhibit — its life. Studies about galactic

Re-Analyzing Low-Energy ('Smudgy') Bursts in a Breakthrough Listen Observation of FRB 121102

FRB 121102 was the first Fast Radio Burst (FRB) source discovered to repeat. Over the course of many observations since its discovery, a significant number of low-energy (or 'smudgy') narrowband bursts have evaded

Status Update of the Breakthrough Listen - TESS - SETI Survey of Exoplanet Host stars

Now in the eleventh month of observations of exoplanet host stars identified by TESS, Breakthrough Listen continues to collect data from the Green Bank Telescope (GBT) and Parkes Telescope in search for technosignatures.

Detection of a new magnetar candidate across 4 - 11 GHz with Breakthrough Listen at GBT

We report a detection of Swift J1818.0-1607 across 4 to 11 GHz (C and X-bands) using the Robert C. Byrd Green Bank Telescope (GBT) and the Breakthrough Listen digital backend (MacMahon et

Searching for ET with X-ray Lenses

In SETI, brighter is better: the more powerful a signal is, the further away we could detect it. Maybe aliens use huge power plants to keep a beacon going in hopes of grabbing

Breakthrough Listen observations of the “Random Transiter” HD 139139

A mysterious stellar system was identified this year, exhibiting 28 transit-like events over 87 days in Kepler data. This system is called EPIC 249706694 / HD 139139, and many proposed astrophysical transit scenarios have
