A close approach to Deimos reveals that its surface does not look like that of an asteroid, hinting at a Martian origin.
Plants Leave Chemical Fingerprints on an Ozone-Depleting Gas
A first-of-its-kind study suggests that isotope analysis could be used to pinpoint sources and sinks of atmospheric methyl chloride.
¿Podría la Vida Estar Flotando en las Nubes de Venus?
Si están presentes, los microbios podrían explicar patrones de evolución en la atmósfera planetaria de Venus, al observarse con luz ultravioleta.
Did Ozone Loss Cause the End Devonian Mass Extinction?
Ozone loss, perhaps as a consequence of a warming climate, may have been responsible for a catastrophic loss of biodiversity.
Solar Properties Rival for Control of Mars’s Bow Shock
While most planetary bow shocks are controlled by the solar wind, at Mars the solar EUV flux is equally important.
Could Life Be Floating in Venus’s Clouds?
If present, microbes could explain evolving patterns in the planet’s atmosphere when observed in ultraviolet light.
Jupiter's Auroras Recharge Between Solar Storms
New research suggests that Jupiter's magnetic field replenishes its stock of plasma during lulls in solar activity, creating spectacular displays when a solar storm hits.
Hubble Gazes at Europa's Aurora
Scientists get their best glimpse yet of the shimmering phenomena on one of Jupiter's most intriguing moons.
Charles A. Barth, 1930–2014
Long-time director of the Laboratory for Atmospheric and Space Physics conducted pioneering studies of the atmospheres of Earth and other planets using ultraviolet spectroscopy.
How Powerful Is Jupiter's Aurora?
Scientists have mapped Jupiter's spectacular aurora in unprecedented detail with the Hubble Space Telescope.
