Bedtime Astronomy

Using more than 500 hours of H.E.S.S. observations of the Milky Way’s center, astronomers searched for gamma-ray signals that could reveal dark matter annihilation.

No definitive signal was found, but the results place powerful new constraints on heavy dark matter and provide the first limits on the thermal Higgsino. These findings could help guide the next generation of gamma-ray observatories.

Using the CHARA Array, astronomers studied 31 evolved stars and discovered that their brightness changes across different wavelengths far more dramatically than current models predict.

The unexpected result exposes a significant gap in our understanding of stellar atmospheres—and could reshape how scientists model the light coming from stars.

New astronomical research is challenging our understanding of both stellar atmospheres and the origins of the Milky Way.

Observations from the CHARA Array show that nearby stars fade toward their edges more strongly in infrared light than current models predict, potentially affecting how astronomers measure stars and exoplanets.

Meanwhile, the MEGATRON simulations are revealing how the first generations of stars and galaxies may have shaped the Milky Way’s early history, incorporating the effects of Population III stars and supernovae.

Scientists have discovered that Earth’s center of mass is constantly shifting as water, snow, ice, and air move around the planet.

Using satellites, GPS data, and improved models, researchers found these seasonal movements are smaller than previously thought—but still large enough to matter for GPS, global mapping, and precision navigation. The findings reveal just how much Earth's surface is constantly reshaping its position in space.

New observations are challenging a long-standing idea about supermassive black holes. Data from thousands of galaxies suggest these giants may grow without violent mergers, using slower processes hidden within their host galaxies.
