PRESS RELEASE
Dr. Matthew Tiscareno will receive the 2026 Carl Sagan Center Director’s Award for scientific leadership, planetary rings research, and mentorship at the SETI Institute. The award recognizes excellence in astrobiology, technology, exploration, public engagement, and mentoring future scientists. Tiscareno’s research includes major discoveries involving Saturn’s rings and Enceladus’ subsurface ocean. -
“What actually happens when you get a SETI detection is that the media immediately start calling you up. There is no secrecy in this work. Usually, within a few hours, everyone would know,” Dr. Seth Shostak told IFLScience.
Back in 1997, a signal was detected that was coming from outside the atmosphere, and it appeared to be artificial. It took the New York Times just 15 hours to find out that there was an odd detection and get in touch with SETI.

Big Picture Science for May. 11, Preventing Future Pandemics
We may not want to think about another pandemic, but, as epidemiologists say, it is once again a “when,” not “if,” scenario. For his latest book, journalist Jon Cohen, who has written extensively about infectious disease for the magazine Science, interviewed top epidemiologists around the world and followed virus hunters into damp and daunting bat caves to assess our pandemic preparedness readiness. Jon and Molly sit down before an audience in Los Angeles to talk about worrisome cuts to science funding and our ability (or inability) to be vigilant and respond quickly to emerging disease. There is good news: we know how to stop outbreaks. The question is, will we put our tools and vast knowledge to use?

Memories from Februaries spent in the #Atacama desert. Team members would take nights off to recover from the heat and do laundry in town, pick up supplies at the hardware store.
Often we had to get those foil-faced windshield covers to protect computers that would overheat in the sun.
Driving through that otherworldly #landscape was exhilarating.

For the second year in a row, the SETI Institute joined in the Atlanta Science Festival’s Exploration Expo in Piedmont Park. The expo drew over 20,000 science lovers, many of whom visited our booth.
This year’s booth theme, “What Would You Say to Aliens,” focused on the Arecibo Message, sent in 1974 from the Arecibo Telescope to the globular cluster M13. The message encoded information about life on Earth, visualized as a grid of binary data.

@Powerfromspace1 in general, shorter wavelengths are scattered more than longer wavelengths. #SETI emphasizes listening via photons -radio or optical https://www.seti.org/research/seti-101/a-primer-on-seti-at-the-seti-institute/. Radio waves have the longest wavelengths in the electromagnetic spectrum https://science.nasa.gov/ems/05_radiowaves. Optical SETI searches for pulses of laser light in or near the visible portion of the light sprectrum, while Radio SETI searches for signals within the radio and microwave portions of the light spectrum https://www.princeton.edu/~willman/observatory/oseti/oseti.html

After a century of listening, we are still alone in the vast cosmos — though that has not killed the hope that radio telescopes could open a line of communication to alien civilizations. In fact, we have barely begun to search the galaxy, having scanned only a fraction of its star systems. But that could soon change thanks to next-generation telescopes and AI-assisted data analysis.

Big Picture Science for May. 04, Shadow of Chernobyl
Forty years later, the exclusion zone surrounding the infamous Chernobyl Nuclear Power Plant remains uninhabited by humans. But among the radioactive remnants, wildlife is flourishing, including endangered species. In the second of our two-part series, we look at the state of the disaster site today, consider what lessons we’ve learned during clean up efforts, hear about a strange story about radioactive shellfish, and consider whether small modular reactors could reinvigorate dreams of a nuclear-powered future and bring nuclear energy out of Chernobyl’s shadow.
Guests:
* Steven Biegalski – Chair of Nuclear and Radiological Engineering and Medical Physics program at Georgia Institute of Technology
* Tom Scott – Professor of Nuclear Materials and Devices at the University of Bristol
* Jacopo Buongiorno – Professor of Nuclear Science and Engineering at MIT, Director of the Center for Advanced Nuclear Energy Systems (CANES), and Director of Science and Technology of the MIT Nuclear Reactor LaboratoryDownload podcast at - https://bigpicturescience.org/episodes/shadow-of-chernobyl

Big Picture Science for April. 27, 2026: 40 Years After Chernobyl
On April 26th, 1986, an explosion at the Chernobyl Nuclear Power Plant in the Soviet Union blasted a plume of radioactive debris a half mile into the sky, blanketing Europe. Witnesses described a laser of blue light eerily shooting up from the reactor core. Built to represent the bright future of nuclear power, Chernobyl instead became the biggest nuclear disaster in history. In the first of a two-part series, we retell the story of the accident, the role that design flaws and human error played, and the futile attempts at radiation containment. We also consider the long shadow the catastrophe cast over nuclear power, and the significant political fallout of the Soviet coverup; the Ukrainian vote for independence and the fall of the U.S.S.R.

* Adam Higginbotham – Journalist and author of “Midnight in Chernobyl: The Untold Story of the World’s Greatest Nuclear Disaster”

RE: https://mastodon.social/@falseknees/116477394235883790
Good SETI cartoon, we're probably missing the obvious signs because we don't recognise it yet.
Got to think outside that box, "what if non-beaked are People too?" -
We’re looking forward to a special Earth Day meeting on citizen science with Megan Li from UCLA SETI and our colleagues in Aotearoa New Zealand, Hari Mogoșanu astrobiology.nz & @kategenevieve.
All welcome, especially students curious about astrobiology and SETI.

Big Picture Science for April. 20, 2026: Skeptic Check: Feeling Risky
REPEAT
It’s not just facts that inform our decisions. They’re also guided by how those facts feel. From deciding whether to buckle our seat belts to addressing climate change, how we regard risk is subjective. In this extended conversation with an expert on the psychology of risk, find out about our exaggerated fears, as well as risks we don’t take seriously enough. Meanwhile, while experts warn society about the dangers of self-aware AI – are those warnings being heeded?Guest:
* David Ropeik – Professor emeritus Harvard University, and expert on the psychology of risk

RE: https://bolesblogs.com/2026/04/19/below-the-mesh/
Two things I've always thought about the Fermi Paradox
1) We don't know what technology They use, so it's just guesswork as to what we're looking for. A bit presumptuous to write off the whole Universe as empty.
2) The Universe is BIG and we're barely explored it yet, we've only been listening for radio for about a 100 Earth years, that's nothing in this big old universe. And who wants to communicate at the Speed of Light? -
Dr. Mia Mace’s scientific research interests lie in numerical modeling of planetary ring systems, and her doctoral work focused on developing code to simulate and analyze the dynamics of charged dust grains in Saturn’s rings in response to questions about ring rain and spokes.

Why #SETI Might Have Been Missing #Alien Signals
Rsearch highlights an overlooked complication: even if #extraterrestrial transmitter produces a perfectly narrow signal, it may not remain narrow by the time it leaves its home system... "If a signal gets broadened by its own star's environment, it can slip below our detection thresholds, even if it's there, potentially helping explain some of the radio silence we've seen in technosignature searches," said Dr. Vishal Gajjar

"...what would happen if an extraterrestrial culture began seeding stars with self-reproducing probes, each capable of not only studying a new world but building another probe that could reach yet another star, and so on? Such probes could use local resources in each system to build their next generation, thus nullifying the resource problem."
