Solar Wind a Major Driver of Atmospheric Sodium at Mercury

by Morgan Rehnberg 27 May 202227 May 2022

MESSENGER observations show a 50% rise in atmospheric sodium-group ions during periods of high solar wind activity.

Road Salts Linked to High Sodium Levels in Tap Water

by Sarah Stanley 8 March 202210 May 2022

Use of deicing agents may sometimes raise sodium levels in drinking water beyond healthy limits for people on salt-restricted diets.

Lake Michigan’s Salinity Is on the Rise

by Robin Donovan 7 February 202228 March 2022

Road salt is primarily to blame for the shift, though the water remains within safe levels for now.

Atmospheric Turbulence May Promote Cloud Droplet Formation

by Morgan Rehnberg 18 March 20217 March 2022

Turbulence causes local variations in relative humidity, which can push particles past a critical saturation threshold for droplet nucleation.

Mmm, Salt—Europa’s Hidden Ocean May Contain the Table Variety

by Katherine Kornei 9 July 20197 March 2022

Hubble Space Telescope observations suggest that sodium chloride exists in young, geologically active regions on Europa, likely fed by upwelling from the moon’s subsurface ocean.

Chemical Patterns May Predict Stars That Host Giant Planets

by Kimberly M. S. Cartier 25 June 20197 March 2022

Stars with giant planets tend to have a few key elements in abundance. A new algorithm used these patterns to predict hundreds of stars that will likely have exoplanets if we go looking for them.

Local Heat Source Needed to Form Liquid Water Lake on Mars

by Terri Cook 12 March 201910 March 2022

Thermal modeling suggests that active magmatism in the past few hundred thousand years could account for the presence of a large lake previously hypothesized beneath the Red Planet’s southern ice cap.
