Neptune is fondly known for being a rich blue and Uranus green – but a new study has revealed that the two ice giants are actually far closer in colour than typically thought.
When researchers reconstructed lava flows on Mars, they realized the red planet is a lot more active than they previously thought.
The picture, resembling a glowing blue marble rippling into a black ocean, was funneled through the telescope’s infrared filters to capture wavelengths future space travelers wouldn’t see with the naked eye.
The scientists made a startling observation when they observed that the atmosphere of Mars dramatically ballooned outwards because of a void created due to a powerful gust of solar wind.
Water from Earth's surface can find its way deep into the planet, and new research explains how it changes the outermost region of the metallic liquid core.
When future astronauts explore Mars's polar regions, they will see a green glow lighting up the night sky. For the first time, a visible nightglow has been detected in the martian atmosphere by ESA's ExoMars mission.
Researchers have made the first direct detection of atomic oxygen in the atmosphere of Venus. Some say it builds the case the planet was more hospitable in the past.
Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
Two new papers show a 150 kilometer-thick layer of molten silicate rock at the base of the mantle envelopes Mars' liquid iron-alloy core.
A recent study suggests that Venus, typically viewed as a fiery wasteland, may have experienced Earth-like plate tectonics in its distant past.
Researchers using the NASA/ESA/CSA James Webb Space Telescope's NIRCam (Near-Infrared Camera) have discovered a high-speed jet stream sitting over Jupiter's equator, above the main cloud decks.
So-called chorus waves have been recorded at Earth, and Jupiter, and Saturn; and observed at Uranus and Neptune. Now, international scientists have detected them whistling around Mercury.
Sunlight on Mars interacts with iron-rich dust that hangs in the atmosphere. This ultimately scatters lower-frequency red light through the sky during the day. At twilight, however, the red light is filtered away and the sky glows a cool blue.
Solving the mystery of how planets like Earth were formed is an important question for understanding the origin of life.
Mercury has shrunk by7 km. Most of this happened long ago, but now we have evidence that it continues.
