Trace Gas Detection Sheds New Light on Atmospheres of Jupiter and Its Volcanic Moon Io

The volcano-laced surface of Jupiter’s moon Io was captured in infrared by the Jovian Infrared Auroral Mapper (JIRAM) imager aboard NASA’s Juno spacecraft as it flew by at a distance of was about 80,000 km (50,000 miles) on July 5, 2022.

Using data from NSF’s Karl G. Jansky Very Large Array (VLA), the Atacama Large Millimeter/submillimeter Array (ALMA) and NASA’s Juno spacecraft, two teams of astronomers have examined the distribution of the trace gas ammonia in the atmosphere of Jupiter, and the gaseous sodium chloride and potassium chloride in the atmosphere of Io in order to investigate their characteristics and infer properties of Io’s volcanoes. This image shows Jupiter’s...

This map illustrates the geography of Beringia, the land bridge that formed between North America and Asia during the last glaciation. Humans crossed Beringia from Asia to North America during the glacial period depicted on this map. Lakes and drainages have been reconstructed to provide a better perspective on the environment of the land mass according to bathymetric data having a grid spacing of 1 km (100 m for Norton Sound). Some of the lake basins are shallow and may have been wetlands rather than open water bodies. Image credit: J.D. Bond / Yukon Geological Survey / Government of Yukon.

This Hubble image shows ESO 415-19, a spiral galaxy located some 450 million light-years away in the southern constellation of Fornax. In the top-right there is a smaller, orange elliptical galaxy. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and the Dark Energy Camera (DECam) on the Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / J. Dalcanton, Dark Energy Survey / DOE / FNAL / DECam / CTIO / NOIRLab / NSF / AURA.
