New research published in the Monthly Notices of the Royal Astronomical Society indicates that the four sub-Earth planets orbiting Barnard’s star are likely composed of the deep-Earth mineral periclase and lack atmospheres. According to University of Cambridge astronomer Xander Byrne and his colleagues, these rocky worlds—located just 6 light-years away—are too hostile to support life … Read more
Solar storm risks to Earth’s infrastructure may be significantly underestimated because there is no known upper limit to how the planet responds to solar wind, according to a study published in Nature. Research led by Nithin Sivadas of NASA and Maria Walach from Lancaster University suggests that previous beliefs in a “leveling off” of atmospheric … Read more
Astronomers using the upgraded GRAVITY+ instrument at the European Southern Observatory’s (ESO) Very Large Telescope Interferometer (VLTI) have determined that the carbon isotope ratio in the atmosphere of the exoplanet Beta Pictoris b is consistent with its current orbital position. According to a study published in Astronomy & Astrophysics by Antonia von Stauffenberg and colleagues, … Read more
Experts at Advancing Earth and Space Sciences (AGU) propose using orbiting spacecraft to release mass-loading material into Earth’s magnetosphere to mitigate solar storms. This artificial plasma shield could reduce the impact of geomagnetic disturbances on technology, spacecraft, and power grids by 50% or more. NASA’s Solar Dynamics Observatory (SDO) captured a strong solar flare released … Read more
New research indicates that planetary rotation and stellar tidal forces significantly alter the atmospheric composition of close-in exoplanets, potentially skewing data collected by space telescopes. A study by K. Arnav and Gopal Hazra, published in June 2026, demonstrates that failing to account for these gravitational effects leads to inaccuracies in measuring molecular abundances, with transit … Read more
Acidophilic fungi are emerging as potential candidates for life within the Venusian clouds, according to research published in the journal Astrobiology. Scientists studying the spores of Acidiella bohemica, Acidomyces acidophilus, and Acidomyces acidothermus found that their UV-Vis light absorption patterns partially overlap with the mysterious ultraviolet absorber that has long puzzled astronomers observing Venus. These … Read more
A fireball 16 times brighter than Venus streaked across the U.S. night sky, spanning over a dozen states before disintegrating over Missouri, according to NASA. The meteor, which traveled at 56,000 mph, was captured by NASA meteor cameras and dashcam footage, offering scientists critical data on atmospheric entry and the frequency of high-intensity space rock … Read more
For decades, astronomers have puzzled over how Mercury—a scorched world orbiting mere millions of miles from the Sun—manages to harbor water ice in its polar regions. A groundbreaking new study published via arXiv provides a compelling answer: the planet is essentially a cosmic trap, expertly hoarding water delivered by cometary impacts. The Comet Connection: How … Read more
Unlocking the Secrets of Planetary Winds: Why Superrotation Matters When you look at the swirling, banded clouds of Jupiter or the thick, mysterious atmosphere of Venus, you are witnessing one of the most fascinating phenomena in fluid dynamics: atmospheric superrotation. While Earth’s winds generally follow predictable patterns, many planets in our solar system—and far beyond—defy … Read more
Beyond Our Backyard: How the Roman Space Telescope Changes the Exoplanet Game For decades, our search for alien worlds has been largely confined to our immediate cosmic neighborhood. While we have confirmed thousands of exoplanets, most are essentially “local” discoveries. That is about to change. With the upcoming launch of NASA’s Nancy Grace Roman Space … Read more
