Scientists Baffled by Neptune's Temperature Swings

Temps should be 'slowly growing warmer, not colder' amid southern summer

(Newser) - Neptune's southern hemisphere has spent the last 17 years in its summer season, yet global temperatures have plummeted. It's a head-scratching finding that leaves astronomers with more questions than answers. "Since we have been observing Neptune during its early southern summer, we would expect temperatures to be...

Evidence of Alien Life Might Emerge in a Cloud of Methane

The trick will be ruling out nonbiological explanations

(Newser) - Methane—a key ingredient in delightful things like swamp gas, flatulence, and fossil-fuel emissions —could also prove to be a key biosignature, i.e., evidence of extraterrestrial life. Thus, the gas is top-of-mind for scientists preparing to receive an influx of data from the James Webb Space Telescope. According...
