NASA and Smithsonian scientists find that greener trees seen in satellite images may warn of upcoming volcanic eruptions. The change is linked to rising carbon dioxide emissions from magma, which trees absorb and display through greener leaves. This method could enhance early warning systems and improve public safety near active volcanoes.

In a significant step for extragalactic astronomy, researchers from the Russian Academy of Sciences have identified 11 new active galactic nuclei (AGNs) through the ART-XC telescope aboard the Spektr-RG space observatory. These AGNs, classified as Seyfert galaxies, span redshifts from 0.028 to 0.258 and display X-ray luminosities typical for the present cosmic epoch. ...

A study led by researchers at Tongji University using NASA's GRACE satellites has observed recent ice gains in Antarctica from 2021 to 2023, mainly due to unusual precipitation. However, the long-term satellite data from 2002 to 2020 shows a significant and accelerating trend of ice loss. However, experts emphasize this short-term gain does not reverse the effects of ...

A newly discovered supernova remnant named “Teleios,” meaning “perfect” in Greek, is astonishing scientists with its rare circular symmetry. Detected using data from ASKAP’s Evolutionary Map of the Universe, Teleios (G305.4–2.2) could be located 7,170 or 25,100 light years away. With a steep spectral index and low surface brightness, its origin is likely a...

NASA’s SWOT satellite, in collaboration with CNES, reveals how submesoscale ocean features just a mile wide drive vital vertical circulation. These small currents transport heat, carbon, and nutrients, profoundly influencing marine ecosystems and climate systems. The mission’s high-resolution data is reshaping how scientists model ocean-atmosphere interactions and...
