Astronomers using the NASA/ESA Hubble Space Telescope have detected massive cyclones and other dynamic weather activity swirling on WASP-121b, an ultrahot-Jupiter...
Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected a brown dwarf with infrared emission from methane, likely due to energy in...
The clouds of Venus are believed to be composed of sulfuric acid and minor constituents including iron-bearing compounds. Respective concentrations of...
Titan, the largest moon of Saturn, has a unique atmosphere that transforms simple gases like methane and nitrogen into more complex organic compounds....
Planets too close to their star are too hot (such as Venus), those too far, are too cold (like Mars), whereas planets in the habitable zone are just right....
As part of the Thor-Davis experiment on the International Space Station (ISS), ESA astronaut Andreas Mogensen has captured images of a phenomenon called...
In an operation that took mission scientists three months to plan, NASA’s Mars Odyssey orbiter captured a series of panoramic images that showcases the...
The end-Cretaceous mass extinction, which included the elimination of all non-avian dinosaurs, occurred after the impact of the Chicxulub asteroid and...
The NASA/ESA/CSA James Webb Space Telescope has begun its scientific mission, which includes the atmospheric characterization of transiting exoplanets....
Using satellite observations, including from ESA’s International Gamma-Ray Astrophysics Laboratory (Integral) mission, and a new developed analytical...
The atmospheric nightglow is observed on Earth. On Mars, it was something expected, yet never observed in visible light until now.
This image shows an...
Atomic oxygen is produced on the dayside of Venus by photolysis of carbon dioxide and carbon monoxide.
Atomic oxygen is a key species in the mesosphere...
NASA has released a beautiful ultraviolet image taken by the Hubble Space Telescope of the gas giant Jupiter.
This Hubble image shows Jupiter in ultraviolet...
In the search for life in the Universe, Earth provides a template of evolution for the one habitable planet we know. Earth’s atmospheric composition...
While the ultraviolet aurora of Uranus has been observed since 1986, no confirmation of the infrared aurora had been observed until now.
An artistic representation...
Venus is the least understood of the terrestrial planets. Despite broad similarities to the Earth in mass and size, Venus has no evidence of plate tectonics...
The newly-discovered intense (140 m/s) jet is confined to ±3° of Jupiter’s equator, is approximately 4,800 km wide, and is located in the gas giant’s...
In new research, scientists from the University of Leeds and elsewhere measured radiocarbon levels in ancient trees preserved within the eroded banks of...
