Das James Webb Space Telescope liefert Wissenschaftlern Hinweise auf mögliche geothermische Aktivitäten auf den Zwergplaneten Makemake und Eris.
“If Eris and Makemake hosted, or perhaps could still host warm, or even hot, geochemistry in their rocky cores, cryovolcanic processes could then deliver methane to the surfaces of these planets, perhaps in geologically recent times,” said Dr. Will Grundy, an astronomer at Lowell Observatory, one of Glein’s co-authors and lead author of a companion paper. “We found a carbon isotope ratio (13C/12C) that suggests relatively recent resurfacing.”
