Science says there should be billions of worlds capable of life.
So why haven’t we found any?
From NASA’s latest discoveries to the unsettling silence of the cosmos, this deep-dive explores one of humanity’s oldest—and most haunting—questions.

When a coronal mass ejection hit 3I/Atlas in Sept 2025, it should have been destroyed.
Instead? It drank the energy and kept going.
Scientists are questioning everything we know about life in the universe. 🧵

#ICYMI: SETI Institute CEO and President Bill Diamond gave a talk earlier this week called "The Search for Life Beyond Earth - How It Works, Where It Stands and Why It Matters." He explored the science and technology of humanity’s efforts to understand the nature and prevalence of life and intelligence beyond Earth, and to answer the question, “Are we alone in the Universe?”

We’re not alone. What are we going to do about it?
This immersive “Situation Room” experience puts you at the table with scientists, strategists, and educators to debate humanity’s next move — in real time. As 3I/ATLAS or some other interstellar object approaches Earth, you decide: respond, retreat, or do nothing?

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.

Once again, we highlight the work of #scientists who are studying #notjustaliens in our quest to understand our universe, including the Moon!
Dr. Megan Seritan studied lunar paleomagnetism at UC Santa Cruz, focusing on lunar swirls. She now works with the Ring-Moon Systems (RMS) Node of the NASA Planetary Data System (PDS), helping manage data from NASA's planetary missions to the outer solar system.

If an extraterrestrial civilization existed with technology similar to ours, would they be able to detect Earth and evidence of humanity? If so, what signals would they detect, and from how far away?
A research team led by Sofia Sheikh of the SETI Institute in Mountain View, California, in collaboration with the Characterizing Atmospheric Technosignatures project and the Penn State Extraterrestrial Intelligence Center, set out to detect answers.
https://www.seti.org/have-we-really-detected-dyson-spheres
Dr. Franck Marchis, a senior planetary astronomer and director of Citizen Science at the SETI Institute, and Dr. Lauren Sgro, outreach manager for LaserSETI and astronomer at the SETI Institute, discussed the possibility of Dyson spheres and recent research in a SETI Institute video. While no aliens have been found (yet!), Dr. Marchis explained that a Dyson Sphere is a hypothetical megastructure built around a star by aliens to harness energy.
In February 1995, a small research organization known as the SETI Institute launched what was then the most comprehensive search for an answer to a centuries-old question: are we alone in the universe?
This Sunday marks the 30th anniversary of the first astronomical observations conducted for the search, named Project Phoenix. These observations were done at the Parkes Observatory on Wiradjuri country in the central west of New South Wales, Australia.
https://www.ted.com/talks/lisa_kaltenegger_are_we_alone_in_the_universe_we_re_close_to_finding_out
Astrophysicist Lisa Kaltenegger explores the thrilling possibility of discovering life beyond Earth, highlighting how cutting-edge technology like the James Webb Space Telescope lets us analyze distant planets for signs of life in unprecedented detail. Could examining these "alien earths" uncover evidence of new life forms and transform our understanding of the cosmos? We may be closer than ever to finding out.
With only 1 day left in 2024, this is your chance to make your support to the SETI Institute go twice as far. Thanks to the incredible generosity of supporters like you, every contribution received before midnight on December 31 will be matched dollar for dollar, up to $20,000!

The [SETI Institute's 40th anniversary] celebration featured an award honoring Jill Tarter, one of SETI’s founding members and a legend in the fields of astrobiology and space engineering. Tarter was doing SETI research for NASA until the 1980s when a few senators yanked the funding, and she split off with a colleague to form the SETI Institute. The nonprofit based in Mountain View still gets about two-thirds of its funding through NASA.
Today marks the 40th anniversary🎉 of the SETI Institute, which was incorporated as a non-profit research institution in the state of California on this day in 1984!
What an extraordinary history the Institute has had and what amazing discoveries and new understandings have been achieved, together with impactful and important education and outreach programs.
Here’s to the next 40 years and the extraordinary knowledge and discoveries yet to come!

TODAY, 9 am PST
Are we alone? Really, though, in a cosmic sense. Forty years ago, the pioneering radio astronomer Jill Tarter co-founded a Bay Area non-profit to support humanity's search for life beyond ourselves. We celebrate the SETI—as in Search for Extraterrestrial Intelligence—Institute’s anniversary and all their contributions to science, which, sadly, do not yet include finding aliens. What do you hope SETI finds in its next forty years?
In their search for life elsewhere, scientists have in recent years become much more interested in the outer solar system’s icy moons, once considered too far from the Sun to plausibly support life. NASA's Europa Clipper is one of several probes heading to (or planned to travel to) those faraway worlds. Will they find signs that life could exist there?

We are excited to share that the SETI Institute will come together to commemorate 40 years of remarkable history and scientific achievements. Since its founding in 1984 by Jill Tarter and Tom Pierson, the SETI Institute has pushed the boundaries of space exploration. Our scientists have consistently unlocked new possibilities in astrobiology, SETI, and beyond. #seti #arewealone

In her new book The Secret Life of the Universe, Nathalie Cabrol presents both a comprehensive guide to how life could have evolved across our solar system and a review of life’s own journey on Earth, using historical, scientific and even spiritual lenses. Cabrol grounds our quest to find and define “life” in the natural balance, the give and take, between the biological and its environment.

As director of the Carl Sagan Center for Research at the SETI Institute, astrobiologist Nathalie A. Cabrol's work focuses on the question of whether we are alone in the universe. In "The Secret Life of the Universe: An Astrobiologist's Search for the Origins and Frontiers of Life," readers gain a deeper understanding of the significant scientific endeavor moving closer to finding an answer.
Experts believe it’s only a matter of time until we find intelligent extraterrestrial life. With new tools and technologies, we search more of the cosmos every day. But what happens when we detect ET? How will we interact? What will we say? A scientist, a poet, and a science communicator explore these questions, grounding their perspectives in science.

The Planetary Society 🤝 SETI Institute
Did you know that the SETI Institute and The Planetary Society have more in common than just a passion for the search for extraterrestrial life? Carl Sagan, one of The Planetary Society’s founders, based the main character of his famous book Contact on the SETI Institute’s founder, Jill Tarter. And we both love the search for life beyond Earth!

In this week's #SETILive, Beth Johnson chatted with Dr. Bonnie Teece about her initial analysis of microbial traps left on the floor of the Atlantic Ocean near Axial Seamount and what they could mean for our search for life beyond Earth, especially involving ocean worlds like Europa and Enceladus.
