What can star variability—changes in a star’s brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted to The Astronomical Journal hopes to address as a team of scientists investigated the interaction between a star’s activity and exoplanetary atmospheres. This study has the potential to help astronomers better understand how star variability plays a role in finding habitable exoplanets, specifically around stars that are different from our Sun.

Young stars buried deep in molecular clouds are bathed in ultraviolet radiation, but they shouldn't be. Protostars are too cold and dim to produce UV light themselves, yet James Webb Space Telescope observations of five stellar nurseries in Ophiuchus reveal its unmistakable signature affecting the surrounding gas. Astronomers tested the obvious explanation that nearby massive stars illuminate these birthplaces but subsequently ruled it out. The UV radiation must be coming from inside the star forming regions themselves, forcing a fundamental rethink of how stars are born.

What is the importance of studying explosive volcanism on Venus? This is what a recent study published in the Journal of Geophysical Research: Planets hopes to address as a team of scientists investigated the potential altitudes of explosive volcanism on Venus. This study has the potential to help scientists better understand the present volcanic activity on Venus, along with gaining insight about its formation and evolution and other planetary bodies throughout the solar system and beyond.

A small space telescope may signal a big new trend for modern astronomy.

NASA's Cassini spacecraft captured dramatic plumes, both large and small, spray water ice out from many locations along the famed 'tiger stripes' near the south pole of Saturn's moon Enceladus.

Google is reportedly in talks to sell its tensor processing units – a type of computer chip specially designed for AI – to other tech companies, a move that could unsettle the dominant chip-maker Nvidia

Dental problems often arise or get worse during pregnancy, and a new study hints that rapid changes to the oral microbiome at this time could be at least partly to blame

A technique called interferometry can greatly magnify tiny objects on the sky, and is powerful enough to reveal the surfaces of nearby stars

The Nancy Grace Roman Space Telescope continues its inexorable march toward launch. It recently completed another series of tests that brings it a few steps closer to a launch pad in Florida. This time, the telescope was split into two separate parts - an inner portion and an outer portion, each of which went through separate tests throughout the fall.
