Astronomers have long thought that the upper clouds of Jupiter, which create the planet’s iconic pale brown belts, are made of frozen ammonia. But a...
Researchers have examined three ice core records to identify lead pollution levels in the Arctic between 500 BCE through 600 CE. Lead isotopes allowed...
On December 24, 2024, NASA’s Parker Solar Probe soared just 6.1 million km (3.8 million miles) above the surface of our home star, racing through the...
The OPAL (Outer Planet Atmospheres Legacy) program obtains long-term baseline observations of Jupiter, Saturn, Uranus, and Neptune in order to understand...
Planetary researcher Tereza Constantinou and her colleagues at the University of Cambridge have examined the chemical composition of the Venusian atmosphere...
These Earth-size ovals at Jupiter’s north and south poles are visible only at ultraviolet (UV) wavelengths, and appear and disappear seemingly at random,...
Astronomers using the NASA/ESA Hubble Space Telescope observed Jupiter’s most distinctive feature, the Great Red Spot, with on eight dates over a single,...
There’s more to thunderclouds than rain and lightning. Along with visible light emissions, thunderclouds can produce intense bursts of gamma rays that...
Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide. But 3.5 billion years ago, the Martian...
There is a significant difference between the two edges of the atmosphere of WASP-107b, a super-Neptune exoplanet about the size of Jupiter but only a...
The end-Permian mass extinction, which occurred about 252 million years ago, was the most severe extinction event in the past 540 million years, eliminating...
Chemists at the Leibniz Institute for Tropospheric Research have provided experimental evidence that sulfurous acid (H2SO3), once formed in the gas phase,...
The images in the Martian Cloud Atlas have been captured by the High Resolution Stereo Camera (HRSC) instrument on ESA’s Mars Express spacecraft.

Mars’ water history is fundamental to understanding an evolution of Earth-like planets. Water escapes to space as atoms, and hydrogen (H) atoms escape...
Although Venus is sometimes referred to as Earth’s twin, its current surface conditions are drastically different, making it inhospitable to life. Not...
Scientists from James Madison University have performed a multi-variable investigation of thunderstorm environments in two distinct geographic regions:...
Two-dimensional (2D) aurora images with full spectrum have been captured by scientists in Japan using the newly-developed hyperspectral camera for auroral...
A new biomaterial called C-ELM incorporates living cyanobacteria into translucent panels that can be mounted on to the interior walls of buildings. As...
One-third of Mars’ surface has shallow-buried water, but it is currently too cold for use by life. Proposals to warm Mars using greenhouse gases require...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected trace amounts of hydrogen sulfide in the atmosphere of the Jupiter-sized exoplanet...
