Why we’re searching for alien ...

3️⃣ Listening to the Galactic Center
A new study scanned the Galactic Center at 150 MHz for alien signals—but once again, silence. If life is out there, why aren’t they talking? Or are we just listening on the wrong frequencies?

SETI Researchers Double-Checked 1 Million Objects for Signs of Alien Signals https://www.universetoday.com/170735/seti-researchers-double-checked-1-million-objects-for-signs-of-alien-signals/ #karlg.janskyverylargearray #radiointerferometry #technosignatures #lifebeyondearth #radioastronomy #algorithm #bigdata #cosmic #seti

Could a twin Earth detect #Earth?

Researchers used a theoretical, modeling-based method, and this study is the first to analyze multiple types of #technosignatures together rather than separately. The findings revealed that radio signals, such as planetary radar emissions from the former Arecibo Observatory, are Earth’s most detectable technosignatures, potentially visible from up to 12,000 light-years away.

"A revolution in #datascience, driven by advances in #AI, is changing how we think about searching for intelligence beyond the Earth, aided by a new willingness to consider novel #technosignatures and modes of searching…and a growing understanding of the range of environments offered by the Solar System and an increasingly diverse set of exoplanets have similarly broadened our ideas about biological possibilities…"

'‘Amazing’ new technology set to transform the search for #AlienLife

A conference in the #UK this week will outline new developments in a project to look for ‘#technosignatures’ of other advanced species'

For the last talk of this session, we‘ve got Ravi Kopparapu on the science of #technosignatures.

A technosignature is any element, molecule, feature,… that shows past or present life. Do we have the technology to detect technology?

We want to use atmospheric spectroscopy to detect biosignatures. What are technosignatures? An example is pollution through industrial activity (NO2) or CFCs or lights.

With enough telescope time, we‘d be able to see that! #ExSSV

Good morning friends! I am back to tell you more from #ExSSV - apologies for skipping yesterday, my mind wasn’t up for it.

Today, we start with #habitability, #biosignatures #technosignatures.

We kick off the session with Tiffany Kataria on assessing #conditions for the origin of #life on #exoplanet. For Tiffany, the origin of life is from geophysics to biophysics and important - habitable doesn’t mean inhabited and the origin of life is a way to rule out these false positives. #ExSSV

We Could Snoop on Extraterrestrial Communications Networks

"Part of the challenge is that we don’t know what the nature of an alien signal might be. It’s a bit like finding a needle in a haystack when you don’t know what the needle looks like."

Searching the SN 1987A SETI Ellipsoid with TESS

"We examined the TESS light curves of these stars during the Ellipsoid crossing event and found no anomalous signatures. We discuss ways to expand this methodology to other surveys, more targets, and different potential signal types."

Fun couple of days at the #BreakthroughListen meeting at #SKAO this week, hearing about all the ways astronomers are searching for evidence of #technosignatures 👽 🛸 (we haven’t found any yet, but there are some really clever search techniques). The best bit? The final day pick n mix selection included UFOs…! 😁
