    Nov. 19 image obtained by Pau Montplet from Breda (Girona) using a C6 telescope at f:7. Original image is in the lower right inset, while a false color 0.6º wide Larson-Sekanina filtered image at 9º shows 3I in negative to remark the antitail pointing to the subsolar point, and several jets getting out from the false nucleus. Two additional arrows mark wavy structures in the jets. Image resolution is 0.7 arcsec/pix. Credit: arXiv (2025). DOI: 10.48550/arxiv.2511.19112

    Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered in erupting icy, volcano-like structures called cryovolcanoes...

    NASA Study suggests Shallow Lakes in Icy Crust of Jupiter’s moon Europa could erupt

    This illustration depicts a plume of water vapor that could potentially be emitted from the icy surface of Jupiter’s moon Europa. New research sheds light on what plumes, if they do exist, could reveal about lakes that may be inside the moon’s crust.

    In the search for life beyond Earth, subsurface bodies of water in our outer solar system are some of the most important targets. That’s why NASA is sending the Europa Clipper spacecraft to Jupiter’s moon Europa: There is strong evidence that under a thick crust of ice, the moon harbors a global ocean that could potentially be habitable.

    But scientists believe the ocean isn’t the only water on Europa...
