With the Space Force now fully operational for a few years, I'm curious about how effective their systems really are in tracking unidentified aerial phenomena (UAPs) as they navigate our airspace and orbit. We’ve seen some improvements in satellite technology and orbital tracking, but I wonder if these advancements necessarily translate to better detection of unknown objects. Are they deploying new sensors that could enhance space domain awareness?
The military’s focus on near-Earth objects has always been significant, but I can’t help but think that the integration of more advanced satellite monitoring systems could improve our understanding of not just potential threats from asteroids, but also any unrecognized activities in the vicinity of Earth. Space Force’s emphasis on data fusion from multiple sources is intriguing; have they made any public statements about how they’re using this data specifically to track UAPs?
It seems like the conversation is shifting a bit, especially with the recent push for greater transparency about space-related phenomena. I know the AARO (All-domain Anomaly Resolution Office) has been trying to centralize information, but I’m curious how much of that information overlaps with what Space Force is doing. Are their capabilities specifically designed for UAP detection, or are they just part of a broader surveillance strategy?
Looking back, past incidents have often shown that what is considered a UAP could simply be an underreported satellite or a misidentified object. With new technology, is Space Force distinguishing these cases more effectively? It would be great to know the extent of their engagement with data from other agencies like NASA or the National Oceanic and Atmospheric Administration. Are there any reported collaborations that could enhance their UAP tracking?
Ultimately, what do you think the future holds for Space Force in this area? Will they continue to expand their capabilities, or do you think we'll see a slowdown as they focus on other pressing space issues? I’d love to get a sense of how the community feels about their current trajectory and effectiveness in UAP tracking.

Has anyone else been keeping up with the latest findings from the Perseverance Rover? Some of its recent analyses seem to point towards ancient microbial life existing in Jezero Crater. I find it intriguing how the rover can analyze rocks and soil samples to reveal signs of past life. The question of whether life ever existed on Mars has been a long-standing debate, but these findings feel like they might shift the conversation in a more concrete direction.
The rover's ability to detect organic compounds and its advanced imaging capabilities really set it apart from previous missions. It's one thing to have hypotheses about life on Mars based purely on surface features, but having physical evidence that suggests biological activity in the past adds a whole new layer to our understanding. I wonder how NASA plans to present these findings in upcoming reports. Will we get more detailed samples back to Earth?
I also can’t help but think about what this means for future exploration. If we confirm any signs of ancient life, it might not only change our view of Mars but also influence how we approach other celestial bodies in our solar system. Europa and Enceladus are already on our radar for potential habitability, but the implications of finding life on Mars could push them even higher on the priority list.
Another aspect that's been on my mind is how these discoveries might affect public interest and funding for space missions. People have often been skeptical about the returns on investment for these missions, but finding concrete evidence of life—past or present—could spark a whole new wave of enthusiasm. Do you think public interest will increase if we confirm life on Mars?
Lastly, it's fascinating to think about how this could influence our understanding of life in the universe more broadly. If Mars had life at one point, it raises questions about the conditions necessary for life to develop elsewhere. The more we learn, the more it feels like we're just scratching the surface of a much larger cosmic picture. Anyone else feeling hopeful or skeptical about what these findings might mean in the broader context of astrobiology and the search for life beyond Earth?

Influential pastors say they’ve been privately warned to prepare their followers for possible UFO disclosure that could challenge core religious beliefs.
Evangelist Perry Stone a well-known evangelist, author and Bible teacher from Tennessee, claims a small group of Christian leaders were invited to a confidential meeting with U.S. intelligence officials. According to him, they were told the government may soon release reports, and possibly videos, suggesting the existence of non-human intelligence, advanced craft, and even “reptilian” beings.
These officials allegedly cautioned that such revelations could lead some believers to question the Bible’s account of creation, potentially causing a crisis of faith. At the same time, they warned that others might panic and turn to churches for answers.
The reported meeting involved approximately six Christian leaders, including Bishop Alan DiDio of the Revival Nation Church, who confirmed that he was a part of the extraordinary gathering. He echoed concerns about the impact of disclosure on religion. They also suggested the process could be framed in a way that portrays Christians negatively or undermines their beliefs.
Separately, political momentum for disclosure appears to be building. Donald Trump has called for the release of UFO-related files, while whistleblower David Grusch says pressure is increasing in Congress, with potential escalation in transparency efforts within the next 60–90 days.
Overall, these pastors urge churches to prepare now, warning that any official disclosure may be both shocking and spiritually destabilizing for many.
Note: I think this is just more hype. It’s always the same pattern, secret meetings, unnamed insiders, and claims that can’t be verified. Then come the shifting timelines and vague predictions like “a big reveal in 60–90 days,” followed by nothing and a new deadline. This cycle has repeated for years.
And even if governments did confirm non-human intelligence someday, it wouldn’t automatically disprove religion. History shows that when beliefs are challenged, religions tend to adapt rather than collapse.

A flare from the Sun. (Image credit: NASA)The most abundant stars are dwarf stars with a tenth of the mass of the Sun. They live for trillions of years (as calculated here), over a hundred times longer than the lifespan of the Sun. If intelligent life was common around low-mass stars, we would find ourselves next to a dwarf star in the future. Why do we exist near the Sun right now, cosmologically speaking?
This is a question that I have asked a decade ago in a paper published in the Journal of Cosmology and Astroparticle Physics, accessible here.
Since dwarf stars are fainter than the Sun, the habitable zone around them — where liquid water may exist on the surface of an Earth-like planet, is closer to the star than the Earth-Sun separation — defined as an Astronomical Unit and abbreviated as AU.
For example, the nearest star to the Sun, Proxima Centauri, has a mass of 0.12 solar masses and a luminosity that is just 0.16% of the solar luminosity. Its habitable zone is between 0.023–0.054 AU (as discussed here), corresponding to an orbital period of 3.6–14 Earth’s days. A rocky planet orbiting within this zone experiences strong tides that tend to lock its spin period to its orbital period, similarly to the Earth’s Moon. This tidal locking minimizes the energy of the system, and means that the planet will have a permanent dayside and a permanent nightside.
As it turns out, Proxima Centauri hosts two planets within its habitable zone (as reported here): Proxima b with a mass of about 1.1 Earth masses, an orbital radius of 0.05 AU and an orbital time of 11.2 Earth days, and Proxima d with a mass of about 0.26 Earth masses, an orbital radius of 0.029 AU and an orbital period of 5.1 days.
Proxima Centauri exhibits violent flares (as reported here) which can strip the atmospheres of close-in planets like Proxima b or Proxima d. In the absence of an atmosphere, these planets would resemble the current Mars, with no liquid water on their surface. This is because surface water can exist in a liquid phase only in the presence of an external atmospheric pressure. The lack of liquid water would in turn deny Proxima b and Proxima d from the opportunity to develop the chemistry of life-as-we-know-it on their surface. The combination of tidal locking and the lack of an atmosphere to moderate differences in surface temperature, implies a large persistent temperature contrast between the permanent dayside and nightside of these planets.
Massive stars are less abundant than solar-mass stars. They are also brighter and shorter-lived than the Sun. They dominated the energy output of early galaxies when the Universe was younger and comparable in age to their lifespan. We should not be surprised to find ourselves in the Solar System at the current cosmic epoch, because the Sun’s lifespan of 12.2 billion years (as calculated here) is similar to the present age of the Universe, 13.8 billion years.
In a recent paper with my brilliant postdoc, Devesh Nandal, accessible here, we showed that the intense ultraviolet radiation and strong winds of massive stars preclude habitability for the period of time required for complex life to develop on Earth. In particular, a 9 solar mass star sustains a habitable zone for only 30 million years at an orbital radius of about 100 AU, and this brief sliver of potential habitability disappears for stars more massive than 15 solar masses.
In addition, early stars in the infant Universe were marked by a low abundance of heavy elements which are essential for making rocky planets and the carbon-based chemistry of terrestrial life.
These universal considerations give a plausible explanation to why we do not exist near a massive star in the past or near a dwarf star in the future, but rather near a middle-aged star like the Sun at the present cosmic epoch.
Putting politics aside, life could not have been better — cosmologically speaking.

A Scientific Alternative to Government Disclosure: The Galileo Project is Now Capable of Discovering UAP
The triangulation-based path of an airplane (red) provides a distance measurement that is within 10% of its actual path (green), based on the latest analysis by the Galileo Project. (Image credit: Richard Cloete and Regina Sarmiento, Galileo Project)A few days ago, I celebrated my birthday by giving the colloquium at Harvard’s Institute for Thery and Computation, for which I served as director over the past twenty years. This hour-long lecture, available here, garnered by now of order ten thousand views. It overviews of the research performed within the Galileo Project that I am leading. The goal of the Galileo Project is to bring the search for extraterrestrial technological artifacts to the mainstream of transparent, validated and systematic scientific research.
The Galileo Project currently operates three observatories in Massachusetts, Pennsylvania and Nevada, with a future observatory planned for Indiana. These observatories monitor the entire sky continuously in the infrared, visible, radio and audio bands, and record data on millions of objects. The data is analyzed by machine learning software, trained to discover outliers with unfamiliar characteristics.
The same airplane is observed as a white dot in the lower-right quarter of the image on the left-hand-side and as a white dot near the center of the image on the right-hand-side (along with three birds flying above it). These two images were taken by two infrared cameras separated by about 10 kilometers. The comparison of the images, along with accurate time stamps, allows to infer the distance of the airplane to within an accuracy of better than 10%. (Image credit: Regina Sarmiento, Galileo Project)For the first time since I co-founded the Project together with Dr. Frank Laukien in July 2021, the Galileo research team under my leadership has reached a major milestone this month. We are now capable of measuring distances to objects in the sky to better than 10%, by observing them from different directions with multiple units separated by 10 kilometers from each other. This method of triangulation, enabled by accurate time stamps, allows us to measure the three-dimensional velocity and acceleration of objects and determine whether any of them lies outside the performance envelopes of human-made technological objects, such as drones, balloons, airplanes, helicopters or satellites.
The goal of the Galileo research team is to figure out whether there are extraterrestrial technological visitors in our backyard. As of now, the Galileo observatories can discover Unidentified Flying Objects (UFOs) or Unidentified Anomalous Phenomena (UAP). Any such discovery, substantiated by scientific-quality data, will be shared through the standard scientific protocol with the public. Instead of waiting for disclosure of classified information on UAP or UFOs, the Galileo research team is simply observing the sky.
We do not need to rely on the official channels of NASA or the U.S. government to tell us whether we are being visited, for the same reason that we did not need the official declaration of the Vatican in 1992 to learn that the Earth moves around the Sun. The Vatican’s official announcement came 382 after Galileo Galilei reached the same conclusion by looking at the sky through his telescope.
For 65 years, the SETI community has been searching for an electromagnetic signal from a distant star system while stubbornly avoiding the search for interstellar visitors near Earth — including a ban on discussing anomalous near-Earth objects at their conferences (as recommended by a committee chaired by Dr. Jason Wright from Penn State University). During the same period of time, the Pentagon and the U.S. intelligence agencies searched the sky for any flying objects from adversarial nations. These government agencies could have therefore been the first to record anomalous objects in the Earth’s atmosphere.
Mainstream astronomers are focused on the search for the chemical fingerprints of microbes in the atmospheres of exoplanets. Indeed, microbes are likely to be far more abundant than intelligent beings, but their chemical fingerprints are challenging to detect unambiguously. It makes sense to harvest low-hanging fruits in our backyard while we invest ten billion dollars in the Habitable World Observatory over the next two decades. This sounds like common sense, but common sense is not always common in academia.
A popular misconception is that interstellar travel requires advanced technologies. But a simple calculation that I posted here with my Harvard College student Shokhruz Kakharov, shows that our own Voyager spacecraft will reach the opposite side of the Milky-Way galaxy relative to the Sun in about a billion years. Given that most stars formed billions of years before the Sun, there was plenty of time for extraterrestrial artifacts to reach our backyard, even if aliens used the 1970s technologies that we exployed to launch the Voyager spacecraft to interstellar space.
What data does the U.S. government store in its classified archives? We do not know. But two weeks ago, former President Obama and current President Trump referred to UAP as real and potentially linked them to aliens. I was delighted to read the following statement of President Trump here: “Based on the tremendous interest shown, I will be directing the Secretary of War and other relevant departments and agencies to begin the process of identifying and releasing government files related to alien and extraterrestrial life, unidentified aerial phenomena (UAP), unidentified flying objects (UFOs), and any and all other information connected to these highly complex but extremely interesting and important matters. GOD BLESS AMERICA!”.
The `Achilles Heel’ of past imagery and video data on UFOs or UAP, such as that presented in UAP congressional hearings over the past four years, is the unknown distances between the moving UAP and the moving cameras that recorded them. A nearby object might appear to move fast across the field of view even though its actual speed is modest. Knowing the time-dependent distances between multiple cameras and the object allows to infer its three-dimensional velocity and acceleration. It is possible that undisclosed data from U.S. Government satellites allows to infer the velocity and acceleration of UAP relative to the ground, as indicated in 2021 here by John Ratclife — the current CIA director. I would be delighted to participate in a review board that analyzes any such data and reports back to President Trump about its implications.
The scientific research agenda of the Galileo Project is complementary to that of the Pentagon or the U.S. intelligence agencies. Whereas theses agencies focus on human-made objects for the purpose of protecting national security, the Galileo research team is focused on non-human-made objects. I told the five new postdocs who joined the Galileo research team this spring that they should feel free to wake me up in the middle of the night if they detect a UAP which clearly deviates from the performance envelope of human-made objects.
Even if the Galileo research team does not find evidence for any extraterrestrial artifact, I will gladly share all lessons learned about the Galileo hardware, software and data with the Pentagon and the intelligence agencies, to help their mission in protecting national security.
However, if we do find evidence for an extraterrestrial artifact, mark my words: I will not waste any time in attending cocktail parties with the Nobel committee members in Stockholm but rather play the Bob Dylan card in ignoring the phone call from this committee. My time will be better spent in finding more details about our extraterrestrial visitors.
