Bedtime Astronomy

Earth is passing through the ancient debris trail of Halley’s Comet, creating the spectacular Orionid meteor shower. With up to 20 meteors per hour under ideal conditions, observers in both hemispheres can witness these cosmic streaks across the night sky. Discover when to watch, why these meteors appear, and how to find the darkest skies for the best viewing experience.

Scientists studying the effects of simulated deep-space travel have uncovered concerning long-term health risks.

Experiments combining cosmic radiation exposure with simulated weightlessness in rats revealed progressive heart scarring, impaired immune recovery, and lasting genetic mutations linked to cardiovascular disease and leukemia.

What might these findings mean for future missions to Mars and beyond, where astronauts face radiation levels far beyond Earth’s protection?

Astronomers have discovered two actively feeding supermassive black holes separated by just 175 parsecs in the distant galaxy system MG B2016+112.

Using gravitational lensing to analyze archival spectral data, researchers uncovered evidence of a compact black hole pair formed during an ancient galactic merger. Their unexpectedly different feeding rates could reveal new clues about how black holes grow and evolve in the early universe.

Japan’s VERTECS nanosatellite has completed its initial tests and begun routine science operations following its June 2026 launch. After confirming its systems and capturing its first visible-light images of deep-space targets, the satellite is ready to investigate extragalactic background radiation.

Over its planned one-year mission, VERTECS will study the faint light associated with distant galaxies, helping astronomers investigate how stars and galaxies formed and uncover new clues about the universe’s history.

Using NASA’s James Webb Space Telescope, astronomers have discovered that the atmosphere of the giant exoplanet WASP-17b is surprisingly asymmetrical.

By tracking starlight passing through its atmosphere, researchers found that powerful winds redistribute heat, causing its evening side to expand more than its cooler morning side. This innovative technique offers a new way to map alien weather in three dimensions, potentially transforming how scientists study the climates of thousands of distant worlds
