The Sample Analysis at Mars (SAM) instrument onboard NASA’s Curiosity rover has measured the seasonal changes in the gases that fill the air directly...
The new device, developed by researchers in the Department of Chemical Engineering at MIT, is based on passing air through a stack of charged electrochemical...
There’s always a lot of extraterrestrial dust floating down to Earth, but this dust is normally only a tiny fraction of the other dust in our atmosphere...
Astronomers using the NASA/ESA Hubble Space Telescope have detected water vapor in the atmosphere of K2-18b, a planet of eight Earth masses in the habitable...
Venus’ surface has never been seen by the human eye because of opaque, highly reflective clouds which permanently cover the planet. What is curious about...
The temperature on the nightsides of short-period gas giants (hot Jupiters) is surprisingly uniform, suggesting the dark sides of these exoplanets have...
Astronomers using the NASA Infrared Telescope Facility (IRTF) have spotted propadiene — a colorless, flammable gas, best known as a fuel for specialized...
An international team of astronomers has managed to peer deep into the Jovian atmosphere using the Atacama Large Millimeter/submillimeter Array (ALMA)...
A team of researchers from Rensselaer Polytechnic Institute and the University of Texas Austin has used a new technique to analyze tiny amounts of gas...
LHS 3844b, a 1.3-Earth-radii terrestrial world in an 11-hour orbit around the small nearby star LHS 3844, very likely has little to no atmosphere and could...
A new study, published in the journal Scientific Reports, has ruled out the possibility that the levels of methane detected in the Martian atmosphere could...
The NASA/ESA Hubble Space Telescope obtained a detailed image of Jupiter on June 27, 2019, when the gas giant was approximately 400 million miles (644...
Astronomers are curious about the two recently-discovered classes of planets not found in the Solar System: the so-called super-Earths and sub-Neptunes,...
NASA announced last week that it had selected the Dragonfly mission to explore the prebiotic organic chemistry and look for signs of life on Titan, the...
The Sample Analysis at Mars (SAM) tunable laser spectrometer onboard Curiosity last week detected surprisingly high levels of the gas methane at Gale Crater:...
Planetary scientists have long observed water-ice clouds in the Martian middle atmosphere (18.6-37.2 miles, or 30-60 km, above the surface). Now, a University...
Between 8 and 2 million years ago, cosmic-ray energy from one or more nearby supernovae reached Earth and pummeled the planet’s atmosphere, initiating...
In the lab, scientists have pinpointed a specific wavelength of infrared light absorbed when molecules of carbon monoxide and nitrogen join together and...
Planetary researchers from NASA’s Juno mission made the first detection beyond Earth of an internal magnetic field that changes over time — a phenomenon...
