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.
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.
Nasa's Perseverance rover has been able to generate 122g of breathable oxygen - enough to sustain a human for three hours on the Red Planet.
Now, for the first time, we have observed a Neptune Storm with Earth-based instruments in unprecedented resolution.
Megastorms occur approximately every 20 to 30 years on Saturn and are similar to hurricanes on Earth, although significantly larger. But unlike Earth’s hurricanes, no one knows what causes megastorms in Saturn’s atmosphere.
New observations of mud cracks made by NASA's Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments.
