The Echoing Universe: How Radio Astronomy Helps Us See the Invisible Cosmos by Emma Chapman, 2026
How learning to "listen" to the universe using radio waves has revolutionized our understanding of everything from gravity to little green men. "Passionate and witty" Publishers Weekly
In space, no one can hear you scream. But the universe is far from silent. It's been speaking all along, broadcasting its stories and secrets, for those who know how to listen.

Während wir hier in Bonn schwitzen ☀️, arbeiten unsere Empfänger an Radioteleskopen unter nahezu „kosmischen Bedingungen“: Sie sind dem absoluten Nullpunkt sehr nahe ❄️.
Damit wir „hören” können, was das Universum uns sendet 📡, werden zentrale Teile der Empfänger auf etwa -260 °C gekühlt 🧊. Diese kryogenen Systeme gehören zu den Low Noise Amplifiers (LNAs) und Receiver-Komponenten der Electronics Division am MPIfR.
Ihre Aufgabe ist es, kosmische Radiosignale zu verstärken, ohne dass diese im eigenen elektronischen Rauschen untergehen 📉. Das Ergebnis sind Empfänger, die so empfindlich sind, dass selbst die schwächsten Signale aus dem All messbar werden 🌌.
Zum Vergleich: Ein Smartphone würde auf dem Mond im Radiobereich ein deutlich messbares Signal erzeugen 📱🌕 – und wäre damit im Vergleich zu vielen astrophysikalischen Quellen sehr stark.

I’m quoted in this Scientific American story about a possible primordial dark/low surface brightness galaxy detected in the radio at #GreenBankObservatory, presented at #AAS243. They took out all the careful caveats of course! (But I know to expect that)

🛰️ Starlink's Signal Leakage Is Threatening Radio Astronomy's Most Critical Frequencies
- Starlink satellites emit unintended signals 10,000 times stronger than target cosmic signals.
- Researchers detected 112,534 Starlink emissions contaminating ITU-protected radio astronomy frequency bands.
- Current ITU regulations ignore unintended satellite hardware leakage, leaving astronomers without legal protection -

Nuestra ‘burbuja’ de radio (~100 años luz) es minúscula frente a la Vía Láctea: por eso el silencio. Un estudio (Cornell, 2016) estima que el contacto no sería probable antes de ~1.500 años. https://aidoo.news/noticia/W00N7Z

Satelliten kommunizieren untereinander und mit Empfangsstationen auf der Erde. Der Kommunikationsweg: Radiostrahlung. Im Idealfall stören die Kommunikationsfrequenzen der Satelliten Radioteleskope nicht. Doch es gibt eine Ausnahme.

Distant galaxies reveal hidden effect from Big Bang: With these data, they observed a decrease in the radio emission which matches prediction from the supernovae electrons interacting with the Cosmic Microwave Background photons.
https://www.physics.ox.ac.uk/news/distant-galaxies-reveal-hidden-effect-big-bang
Something for the specialists perhaps, but nice to see evidence for this effect (we have been talking about for ages).
