Middle Atmosphere of Mars is Driven by Gravity Waves, New Research Suggests

Mar 6, 2025 by News Staff

Atmospheric gravity waves play a crucial role in driving latitudinal air currents on the Red Planet, particularly at high altitudes, according to a new...

Three waves can be seen in this image, which is an excerpt of a JunoCam image taken on February 2, 2017, during Juno’s fourth flyby of Jupiter. The region imaged in this picture is part of the visibly dark band just north of Jupiter’s equator known as the North Equatorial Belt. Most of this belt is characterized by downwelling motions, but during the fourth flyby it had several bright areas of upwelling clouds. One of those upwelling clouds appears to be accompanied by dark regions, which are most likely shadows. The shadow associated with the center of the three waves is about 25 miles (40 km) long; from the angle of illumination, researchers deduced that the shadowed part of the wave must be around 4 miles (7 km) above the main cloud deck, with the peak of the wave probably close to 6 miles (10 km) above the main cloud deck.

Juno Spots ‘Waves Trains’ in Jovian Atmosphere

Nov 6, 2018 by News Staff

NASA’s Juno orbiter has detected ‘wave trains’ — massive structures of moving air that appear like waves — in the atmosphere of Jupiter. Three...

Flaring, active regions of the Sun are highlighted in this image combining observations from several telescopes. High-energy X-rays from NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) are shown in blue; low-energy X-rays from Japan’s Hinode spacecraft are green; and extreme ultraviolet light from NASA’s Solar Dynamics Observatory (SDO) is yellow and red. All three telescopes captured their solar images around the same time on April 29, 2015. Image credit: NASA / JPL-Caltech / GSFC / JAXA.

Sun’s Core Rotates Nearly 4 Times Faster than Its Surface, SOHO Data Reveal
