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.
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.
For the first time in nearly three decades of observations, clouds seen on Neptune have all but vanished. The observations reveal a connection between Neptune's disappearing clouds and the solar cycle.
New observations of mud cracks made by NASA's Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments.
This hypothetical planet is provisionally known as Planet 9. Computer simulations show it must be a very large planet, consisting of between four and eight times the mass of the Earth and at least ten times the distance of Pluto.
French researchers suggesting that the tallest volcano in Solar System, Olympus Mons on Mars was once a volcanic island, surrounded by a deep sea.
Data collected by the BepiColombo spacecraft traces the causes of the strange aurora, which course through the planet's weak magnetosphere.
NASA's Juno spacecraft orbiting Jupiter frequently encounters giant swirling waves at the boundary between the solar wind and Jupiter's magnetosphere.
Researchers poring over imagery and data from the Perseverance rover on Mars have found evidence of organic molecules in the planet’s Jezero Crater, potentially providing evidence of the planet’s carbon cycles and its ability to host life.
Four small rooms, a gym and a lot of red sand - NASA unveiled its new Mars-simulation habitat, in which volunteers will live for a year at a time to test what life will be like on future missions to Earth.
