I don’t like to give arXiv.org a free pass, since it doesn’t work to the same standards as a peer-reviewed journal. But interstellar object 3I/ATLAS is moving fast, too fast for the independent review process to function. So if we… Read More »Net Paper: 3I/ATLAS Traffic
The journal called “Space Science Reviews” means all three. Just now (vol. 221), they have covered the Lucy mission, and covered it quite well: Levison, H.F. Marchi, S. Noll, K.S. et al. NASA’S Lucy Mission to Trojan Asteroids: Unraveling the… Read More »Space Science Reviews Lucy
It’s official and it’s named. The object, provisionally designated A11pl3Z, showed ‘fuzziness’ (nebulosity, likely from activity) and was then given the comet designation C/2025 N1. Official discovery credit goes to the ATLAS network, Chile site (Rio Hurtado)- hence, the third designation.… Read More »Interstellar Object 3I/ATLAS
The coverage and hoopla around the Vera C. Rubin Observatory have died down a bit. Mentioned briefly in the First Look Event was the Skyviewer “app” (actually an interactive website, skyviewer.app), which includes a sonification tool (Skysynth). This site/app allows… Read More »Vera Rubin Uploading
