Astronomers surprised by ‘dramatic warming’ at  Neptune’s south pole

Planetary temperature conundrums are not confined to Earth. Nobody foresaw the observed changes that occurred on Neptune between 2018 and 2020.

An international team of astronomers have used ground-based telescopes, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track Neptune’s atmospheric temperatures over a 17-year period, Phys.org.

They found a surprising drop in Neptune’s global temperatures followed by a dramatic warming at its south pole.

“This change was unexpected,” says Michael Roman, a postdoctoral research associate at the University of Leicester, UK, and lead author of the study published today in The Planetary Science Journal. “Since we have been observing Neptune during its early southern summer, we expected temperatures to be slowly growing warmer, not colder.”
