Bedtime Astronomy

How did the first stars transform the early universe? The MEGATRON project uses powerful cosmological simulations to trace the birth of primordial galaxies, the spread of starlight, and the creation of the first chemical elements.

By connecting James Webb Space Telescope observations with clues preserved in ancient stars, the research offers a new way to investigate how the universe became enriched with the elements we see today.

A new view of the Sun is revealing that its magnetic canopy is far more intricate than scientists expected.

Using the Sunrise-III observatory and its high-resolution SCIP instrument from 35 kilometers above Earth, researchers captured delicate magnetic structures hidden above quiet solar regions. The observations could help explain how magnetic energy moves through the Sun’s atmosphere and contributes to its extreme heating.

NASA’s Nancy Grace Roman Space Telescope is designed to watch the universe change with an unprecedented combination of sharp images and a huge field of view.

By repeatedly scanning millions of stars, Roman could discover thousands of distant exoplanets, uncover hidden black holes, capture supernovae, and reveal how the smallest stars evolve. It will offer an entirely new way to explore a constantly changing cosmos.

Modern telescopes use thousands of tiny robotic positioners to target distant stars and galaxies, but mechanical limits can leave surprising gaps in cosmic surveys.

Researchers have now developed a simulation tool that acts like a flight simulator for these robotic telescope systems, allowing engineers to test designs before building them. The results reveal which changes can dramatically improve observation efficiency and help create more complete maps of the universe.
