Dr. Ariel Graykowski is a Postdoctoral Fellow focused on the astronomy of small bodies, working with citizen scientists to monitor cometary activity through the Unistellar Network.
She graduated with her PhD in geophysics and space physics from UCLA's EPSS department, where she studied the properties of the irregular satellites of the giant planets as well as fragmenting comets.

In July 2025, 3I/ATLAS, a fast-moving interstellar object, entered our solar system. It’s likely natural, but what if it’s not? What if telescopes confirm it’s artificial? What if it’s sending us a signal? This immersive “Situation Room” experience puts you at the table with scientists, strategists, and educators to debate humanity’s next move — in real time.

Dr. Rosalba Bonaccorsi has expanded her work by developing analytical protocols for real-time in-situ life detection in planetary-like materials and extreme environments worldwide.
Dr. Bonaccorsi has been the experimental lead of a novel project at the NASA Ames Vertical Gun Range (AVGR) facility simulating ice grain plume ejecta for Icy Moons/Ocean Worlds science.
Here is an #Introduction. My current project is about #emergentBehavior in #animalNetworks. I also study consequences of #climateChange. I often wonder how to explain basic concepts of #ecology and #statistics to students. What else: #consciousness (with #panPsychic bias), #seti and #youWouldntLikeToKnow
Daniela de Paulis's paper - 'A Sign in Space as Optical SETI: Laser transmission of a simulated extraterrestrial message' - in collaboration with quantum cryptography researchers Giulia Guarda and Sebastiano Cocchi (University of Florence), is now online.

SETI Post-Detection Futures: Directions for Technosignature Research and Readiness https://astrobiology.com/2025/07/seti-post-detection-futures-directions-for-technosignature-research-and-readiness.html
Happy to see our NASA DARES White Paper on Post-Discovery/Post-Detection Futures up on arXiv. 6 key areas for growing readiness for the discovery of life beyond Earth.
Our paper doesn’t mention “aliens” at all, yet that’s inevitably the word the media lead with.
A perennial problem, related to the so-called “giggle factor” that haunts the question of life beyond Earth.
To me, the question of life in the universe shifts how we think about climate & this planet; understanding Earth as a rare island of life in a vast cosmic ocean grants a usefully humbling perspective.
(Though I admit I grew up reading a lot of Sagan!)

@setiinstitute Send high power radar and radio signals to the object. High power lidar, too. Let's learn as much as we can. #seti #meti
@valkyrie aw, maaaaan, I recall testing #SETI for #BeOS in 199... uh... no, 2001... no, 2002....... uh... I'm ... uh ... old.

# Musk is messing with the Cosmic Dawn. Will alien hunters save the day for all mankind?
## Science friction at the far end of time for SpaceX and astronomy
"Elon Musk's Starlink flying circus is many things. It's a multi-thousand satellite global internet provider, growing by hundreds of new orbiting relays a month. It's part of intricate geopolitical power games between the Pentagon, the US government, Ukraine, and Musk himself.
"It loves photobombing astronomy photographs, as the satellites drift across fields of view that were intended to snap distant starlight. But for its latest trick, it's humming loudly over the faintest whispers from the dawn of the universe. …"
Why do alien encounters always involve the alien putting something up the ass?
A #Galactic Habitable Zone excludes stars too close to the galactic center. Our Sun is a nice distance away from the galactic center, about 28,000 light years. Keeping out of the way of the Galaxy’s spiral arms is another requirement of the Galactic #HabitableZone https://astrobiology.nasa.gov/news/galactic-habitable-zones/
Something has come in from Interstellar space so Avi Loeb claims ownership of it....

Please dude, just stop.
Cool science. Not aliens.

@jimsalter Even if the odds are minuscule, I would like us to attempt high-power focused radio transmissions to candidate systems that could detect us, on the chance anyone was there to receive us. #meti #seti https://mrflash818.livejournal.com/229959.html
ist euch eigentlich schon mal aufgefallen, das die Geräte für die Suche nach intelligentem Leben alle von der Erde weg schauen ?
Das kann kein Zufall sein.
A recently released documentary film celebrates the concept of first contact with aliens and highlights the importance of SETI research in promoting peaceful coexistence in our galaxy. OK, it’s not quite a documentary, but Pixar’s Elio is a fun, fascinating and fabulous adventure story. The film tells the tale of our first encounter with aliens, lots of them, and how that contact will change our perception of the cosmos.
