A new study reveals that the biggest barrier to space-based solar power isn’t in orbit—it’s on Earth. Researchers found that while thousands of satellites could technically beam solar energy from geostationary orbit, real-world factors like limited land for rectennas near the equator sharply reduce that number.Even so, the analysis shows SBSP could still provide up to 3% of global power, underscoring its potential as a future clean energy source.

In dieser Folge führen euch Eva und Jana an die Grenzen von Raum, Zeit und Vorstellungskraft: Es geht vom Wärmetod über den Big Rip bis zum Big Crunch. Wir sprechen über den kosmischen Wettstreit zwischen Gravitation und Dunkler Energie, über Sternleichen, Schwarze Löcher und die fünf Ären des Universums – vom hellen Anfang bis zum Dunklen Ende.Eine Reise in die fernste Zukunft des Univerums, in der selbst Zeit an Bedeutung verliert.

Astronomy Cast Ep. 769: Little Red Dots By Fraser Cain & Dr. Pamela Gay Streamed live on Oct 20, 2025. New instruments bring new mysteries, and when James Webb came on line it uncovered a collection of strange, compact, bright objects shifted deeply into the red end of the spectrum. These were dubbed "Little red dots" or LRDs. And the astronomical community continues to puzzle over what they are. When JWST first peered into the distant past, it discovered the early universe had a rash of little red

Kip Thorne est l’un des physiciens théoriciens les plus influents de notre époque, reconnu pour ses travaux sur la relativité générale, les trous noirs et les ondes gravitationnelles. Conseiller scientifique du film Interstellar, il a également contribué à rendre des concepts complexes accessibles au grand public. Lauréat du prix Nobel de physique en 2017, il a joué un rôle clé dans la détection des ondes gravitationnelles par l’observatoire LIGO.Dans cette vidéo, nous explorerons sa carrière,

This is your Astronomy Tonight podcast.On this day, October 27th, in the year 1961, NASA launched one of the most peculiar satellites ever to orbit our planet. The Echo 1A satellite, affectionately nicknamed the "Skyball" or "Star of Hope," was essentially a giant, shiny space balloon. Measuring 100 feet (30.5 meters) in diameter, this metallic sphere was made of a thin plastic film coated with aluminum. It was so reflective that it became the brightest object in the night sky, outshining even the

Discovering Tatooine's Twin: Astronomers have unveiled a remarkable binary star system, TOI2267, located 190 light years away, featuring three Earth-sized exoplanets orbiting two suns. This unprecedented arrangement challenges existing models of planet formation, suggesting that stable rocky planets can thrive in chaotic environments.Exploring ISS History: A new interactive website, ISS in Real Time, allows users to experience 25 years of International Space Station history.

Big “wobbles” in Earth’s magnetic field more than 40,000 years ago could have made the cultures of the time feel wobbly as well. Early modern humans might have adapted to the wobbly field better than Neanderthals. Earth’s magnetic field protects the surface from high levels of solar radiation. But during a period known as the Laschamp Excursion, which began 42,000 years ago, the field weakened to just 10 percent of its current intensity. And instead of acting like a bar
