Surprising Changes in Neptune’s Temperatures Detected by Astronomers

[ad_1] Over a 17-year period, an international team of astronomers monitored Neptune’s atmospheric temperatures. They discovered that Neptune’s global temperatures dropped unexpectedly, followed by a dramatic warming at its south pole. Credit: ESO/M.

Unexpected Atmospheric Temperature Changes Detected on Neptune

[ad_1] Observed changes in Neptune’s thermal-infrared brightness, a measure of temperature in Neptune’s atmosphere. The plot shows the relative change in the thermal-infrared brightness from Neptune’s stratosphere with time for all existing images taken by ground-based telescopes. Brighter images are interpreted as warmer. Corresponding thermal-infrared images (top) at wavelengths of ~12 µm show Neptune’s appearance […]
