КАК ОТКРЫВАЮТ ПЛАНЕТЫ; КУДА УЛЕТЕЛ ВОЯДЖЕР-1; КАК ПРОБУЖДАЮТСЯ ЧЕРНЫЕ ДЫРЫ? События нашей Вселенной.

How do astronomers find planets around other stars? The transit and radial velocity methods: measurement accuracy has increased from kilometers per second to centimeters. The HARPS and ESPRESSO spectrographs allow us to analyze the atmospheres of distant worlds. What can be learned: size, mass, temperature, presence of clouds, and even habitability. In this issue of Cosmicon: — Exoplanet HD 137010 b: Earth-sized, with a year like Earth (355 days), but a temperature of -68°C. Is there life? Astrophysicist Boris Stern and biologist Mikhail Nikitin explain. — Voyager 1: a signal from 25 billion km away was received by amateur radio enthusiasts with a telescope in 1956. How do engines work after 50 years? And what is recorded on the Golden Record? — A black hole awakens after 100 million years of slumber. Jets a million light years long—does this pose a threat to us? Could Sagittarius A* awaken? Physicist Nathan Eismont is also with us. More details: — How graduate student Alexander Wenner found an exoplanet in the old Kepler archives — How exoplanets, their atmospheres, masses, orbits, and life cycles are studied in general — Why a temperature of -68°C doesn't mean the world is dead — How amateurs from the Netherlands caught the weakest signal from Voyager 1 from a distance of over 25 billion km — Why Voyager is still alive, what it's powered by, and how NASA radio literally "revived" its engine — Why it's impossible to transmit a command to the probe from an external source — How a supermassive black hole can "wake up" — Why it doesn't suck in everything, but instead ejects jets a quarter to a million light years away — And do such processes threaten us or our galaxy With us in this issue: Boris Stern — Astrophysicist Mikhail Nikitin — Evolutionary Biologist Nathan Eismont — Doctor of Physical and Mathematical Sciences, Space Research Institute RAS This episode is about how science works today: archival data, precise spectrographs, amateur observations, spacecraft, and big questions about life, intelligence, and the structure of the Universe. Let us know in the comments: Which of the three stories impressed you most—a planet from an archive, Voyager's whisper, or the awakening of a black hole? 🔗 WE'RE ON SOCIAL MEDIA TG: https://t.me/styknauk MAX: https://max.ru/id682199091746_biz VKontakte: https://vk.com/styknauk Zen: https://dzen.ru/styknauk Rutube: https://rutube.ru/u/styknauk ⏱ Timestamps 00:00 Hello, Earthlings 00:15 A Planet from the Kepler Archive 01:50 What Exactly Did Alexander Wenner Find 03:00 Why Exoplanets Can't Just Be Photographed 03:50 How Old Archives Produce New Discoveries 04:40 Why Does the Planet Have a Strange Name 05:30 Does It Have an Atmosphere? 06:20 How Does the Transit Method Work? 07:40 The Radial Velocity Method and the Doppler Effect 09:10 How Accurate Are Modern Methods Spectrographs 10:50 Methods are always double-checked 12:10 Why what is already known about this planet 13:20 Why -68°C is not a death sentence 14:30 Conditions for life: what really matters 16:00 What can be learned from the atmosphere 17:20 Why we need more research 18:40 What will provide the first evidence of life 19:50 Voyager 1: a signal from the edge of the solar system 20:50 How far away is it now 21:40 How radio amateurs caught the signal 22:50 What does it eat after 50 years 23:40 How Voyager maintains contact with Earth 24:50 Why the engine has to be revived 26:10 Is it possible to send a signal to Voyager 27:00 The Dwingeloo telescope and the old antenna 28:10 The Golden Record and a message to the Universe 29:00 Is it dangerous to share coordinates Earth 30:10 The History of Pulsars and "Signal Fear" 31:10 When Voyager Goes Silent 32:00 A Black Hole That Has Been Dormant for 100 Million Years 33:00 What Happened in the Galaxy 33:50 Why a Black Hole Doesn't "Suck in" 34:50 How Giant Jets Are Born 35:40 Why a Black Hole Could Awaken 36:20 What Falls into the Accretion Disk 37:00 Is It Dangerous for Us? 37:30 Could Sagittarius A* Awaken? 37:55 Summary of the Issue Subscribe to "Cosmicon" to stay up-to-date with the Universe. #exoplanets #earthsearch #voyager #blackhole #space #nasa #astronomy #science #cosmicon In this episode of Cosmicon, we explore three real-life space stories. The instructions sound like science fiction, but the method is confirmed by observations.
