SETI InstituteA new partnership between the SETI Institute and SkyMapper is bringing telescope data on-chain—making observations cryptographically verifiable and reproducible.
This “Proof of Space Observation” approach could transform how scientific data is trusted and shared globally. 🔭
Bi SasquatchBig Picture Science for April. 13, 2026: Old School
Antarctic scientists have long known the region’s ice sheet holds clues to the planet’s ancient past. Yet even the field’s foremost experts were shocked when they extracted a six-million-year-old ice core — twice as old as expected and the oldest recorded so far. Researchers say it will provide one of our best looks ever into Earth's climatological record. In a relatively more recent past, the discovery of 40,000-year-old notches and lines carved into artifacts and cave walls in Germany, examples of protowriting, suggest humans began documenting ideas thousands of years earlier than thought. Those timescales pale however, when compared to the age of the Earth’s most ancient rocks, which have a story to tell too. Find out how the planet’s most venerable rocks, formed billions of years ago, reveal the geological conditions that allowed life to get a foothold.
Guests:
* Huw Groucutt – Archeologist, Department of Classics and Archeology, University of Malta
* Ed Brook – Paleoclimatologist and professor of Earth, Ocean and Atmospheric Sciences at Oregon State University
* Simon Lamb – Earth scientist and professor of geography in the School of Geography, Environment and Earth Sciences at Victoria University at Wellington, New Zealand. Author of “The Oldest Rocks on Earth: A Search for the Origins of Our World.”

Habr[Перевод] Почему мы ещё не нашли сигналы инопланетной жизни? Интервью с астрономом
Вселенная остаётся безмолвной. Несмотря на десятки лет поисков, мы ещё ни разу не обнаружили сообщений от нечеловеческих форм жизни. Одно из потенциальных объяснений этого предлагает гипотеза «тёмного леса». Согласно ей, Вселенная молчит, потому что она подобна тёмной и тенистой лесной местности, в которой могут таиться хищники. Поэтому разумные виды вряд ли сообщат о себе из страха, что более совершенная или враждебная цивилизация мгновенно их уничтожит. Гипотеза позаимствовала своё название из романа Лю Цысиня «Тёмный лес», но сама идея предшествовала книге. Астроном Вишал Гаджар — исследователь из Института SETI и участник Breakthrough Listen Program — самого большого научного проекта по поиску разумной жизни. В моём недавнем интервью с ним он упомянул гипотезу «тёмного леса». Гаджар — соавтор научной статьи в The Astrophysical Journal , согласно которой космическая погода вокруг звёзд может препятствовать получению нами сигналов от инопланетных форм жизни. Я задал ему вопрос: если однажды мы обнаружим сообщения от инопланетян, должны ли мы ответить им? Он ответил, что для человечества Вселенная по-прежнему остаётся очень тёмным лесом. «Если находишься в кромешно тёмном лесу, не стоит издавать звуки, чтобы привлечь к себе внимание. Аналогично, я бы не советовал передавать сигналы инопланетянам». Он не говорит, что этого не стоит делать вообще; просто время ещё не пришло. У нас не только нет необходимых для коммуникации технологий, но мы ещё и юный вид, слишком погружённый во внутренние конфликты. Мы обсудили с Гаджаром его находки, его оптимистичный настрой и те типы сигналов, которые нам нужно искать. Также мы обсудили теории заговоров, связанные с НЛО, фильм «День независимости» и возможный внешний вид инопланетян.

Alien Megastructures May Be Physically Feasible, a New Study Suggests
Alien megastructures built to harvest stellar energy or alter the orbits of stars may be physically feasible, according to a new analysis – satisfying both our sci-fi fancies and our innate yearning to not feel so alone in a large, cold Universe.

First Lunar Farside SETI Observations for Periodic Signals with the Low-frequency Radio Spectrometer of Chang'E-4 Mission
Chang'E-4 (CE4), the first mission to soft-land on the lunar farside, provides a unique opportunity for astronomical observations from an environment shielded from terrestrial radio interference, and thus serves as pathfinder for lunar farside radio search for extraterrestrial intelligence (SETI) studies. We present a search for periodic technosignatures using low-frequency radio observations from the CE-4 mission, the first radio SETI study based on data from on the observation in lunar farside. We analyze the CE4 dynamic spectra with a component-level framework that combines principal component analysis (PCA), cross-antenna basis alignment, as well as temporal periodicity and frequency comb structure diagnostics. No final periodic candidate signal is found after the selection procedure, and we therefore find no evidence in the present CE4 sample for a credible periodic artificial signal. This study serves as a pathfinder and provides a practical framework for lunar radio SETI analysis. As more future lunar missions begin to incorporate radio instrumentation, lunar farside may become a promising site for expanding radio SETI research.
"There are trillions of galaxies. Each galaxy has hundreds of billions of stars. Each star has at least two planets. And 10% of them are very likely similar to our own," says French-American astronomer Franck Marchis. His conclusion: "It is impossible that there isn't other intelligent life elsewhere in our universe."

Les astronautes de la mission Artémis 2 viennent de mettre le cap vers la Lune, une première en un demi-siècle. Un retour vers l'espace qui inspire à France 24 une question : où en est la science dans la quête de signes de vie extraterrestre ?
