An international research team led by the University of Vienna has discovered that the Solar System traversed the Orion star-forming complex, a component of the Radcliffe Wave galactic structure, approximately 14 million years ago. This journey through a dense region of space could have compressed the heliosphere, the protective bubble surrounding our solar system, and increased the influx of interstellar dust, potentially influencing Earth's climate and leaving traces in geological records. The findings, published in Astronomy & Astrophysics, offer a fascinating interdisciplinary link between astrophysics, paleoclimatology, and geology.

Using the James Webb Space Telescope, astronomers investigate the extreme weather patterns and atmospheric properties of exoplanet LTT 9779 b. New JWST observations with NIRISS reveal a dynamic atmosphere: powerful winds sweep around the planet, shaping mineral clouds as they condense into a bright, white arc on the slightly cooler western side of the dayside. As these clouds move eastward, they evaporate under the intense heat, leaving the eastern dayside with clear skies.

The Red Planet’s iconic rusty dust has a much wetter history than previously assumed, find scientists combining European Space Agency (ESA) and NASA spacecraft data with new laboratory experiments on replica Mars dust. The results suggest that Mars rusted early in the planet’s ancient past, when liquid water was more widespread.

Scientists have found Siamese fighting fish are typically kept in containers just one-quarter the size they need to thrive, challenging decades of retail practice in the ornamental fish industry worldwide.
