Bedtime Astronomy

The Euclid space telescope has discovered 31 ancient quasars, including the two most distant ever detected, dating to when the universe was just 670 million years old.

Their unexpectedly massive supermassive black holes challenge current theories of cosmic evolution. In this episode, we explore how these brilliant objects reveal the cosmic dawn, what they tell us about the epoch of reionization, and how the James Webb Space Telescope could uncover the secrets behind their astonishingly rapid growth.

A study of more than 155,000 Milky Way stars offers compelling new clues about the universe's true age.

By examining some of the galaxy's oldest stars, astronomers provide an independent test of leading cosmological theories while revealing new insights into the ongoing Hubble tension.

The findings strengthen our understanding of the universe's earliest history without fully resolving one of astronomy's biggest mysteries.

Researchers have proposed a surprising new way to predict the outcome of black hole collisions using thermodynamics instead of massive supercomputer simulations.

The study suggests that merging black holes naturally evolve toward a state of maximum entropy, with gravitational waves carrying away excess energy. If confirmed, this elegant approach could simplify our understanding of black hole mergers and reveal that the laws of thermodynamics play a fundamental role in shaping spacetime itself.

Why are so few exoplanets about 1.8 times the size of Earth? This episode explores NASA's proposed Early eVolution Explorer (EVE) mission, designed to investigate the mysterious "radius valley" that separates rocky super-Earths from gas-rich sub-Neptunes.

By studying young star clusters and newly formed planets, EVE aims to reveal whether these worlds are born different or transformed over time, offering new insights into how planetary systems evolve.
