ЧЁРНАЯ ДЫРА ПРОСНУЛАСЬ? Откуда берётся газ для Стрельца А* и почему это важно для нас

🌌 WHAT FEEDS THE BLACK HOLE AT THE CENTER OF THE MILKWAY? A large international team of astrophysicists has discovered where the supermassive black hole Sagittarius A* at the center of our galaxy gets its material. It turns out it's a binary star with a powerful stellar wind. When these gas streams collide, they lose energy and fall onto the black hole in chunks the mass of Earth. Astronomer Vladimir Goradzhanov, a research fellow at the Sternberg Astronomical Institute of Moscow State University, discusses the feeding of black holes, light echoes, radio fibers, and how Russian scientists reconstructed 12 billion years of the history of a distant galaxy from the chemical composition of its stars. 👉 TIMESTAMPS: 00:00 — Hello, Earthlings! 00:35 — HOW DO WE KNOW THERE'S A BLACK HOLE IN THE CENTER? 02:50 — HOW BLACK HOLES GAIN MASS 04:10 — ACTIVE AND INACTIVE BLACK HOLES 05:30 — WHY ACCRETION IS UNEVEN 06:50 — WHAT A BLACK HOLE LOOKS LIKE IN 3D 08:10 — WHAT ARE THE SIZES OF BLACK HOLES 09:30 — WHO HAS STUDIED BLACK HOLES AND WHY 10:40 — THE MAIN DISCOVERY: WHAT SAGITTARIUS A* FEEDS ON 11:50 — WHAT IS STELLAR WIND 13:00 — HOW GAS FALLS INTO A BLACK HOLE 14:10 — THE EDDINGTON LIMIT: WHY A BLACK HOLE CANNOT BE GREEDY 15:30 — HOW THE NUCLEI OF DISTANT GALAXIES ARE STUDIED 16:40 — WHAT ARE JETS AND HOW DO THEY WORK 17:50 — LIGHT ECHO: HOW TO SEE A QUITTED BLACK HOLE 19:00 — IONIZATION ECHO AND RADIO FIBER 20:10 — HOW BLACK HOLES SWITCH MODES 21:20 — DO BLACK HOLES AFFECT GALAXY LIFE? 22:30 — HOW CHEMISTRY HAS REVEALED 12 BILLION YEARS OF EVOLUTION 23:30 — WHY OXYGEN KEY MARKER 24:20 — WHAT DOES STUDYING GALAXIES TELL US? 25:30 — WHY DO GALAXY NUCLEI FORM FASTER? 26:40 — HOW CHEMISTRY DETERMINED THAT A GALAXY HAS EATEN ITS NEIGHBORS? 27:50 — COMPUTER SIMULATIONS OF GALAXIES 29:00 — IS IT POSSIBLE TO LOOK EVEN FURTHER? 30:10 — WHY WAS NGC 1365 CHOSE? 31:20 — HOW STUDYING GALAXIES CHANGES OUR IDEAS ABOUT THE UNIVERSE? 32:30 — WHAT OTHER METHODS DO SCIENTISTS USE? 33:40 — WHAT IS A BULGE?
