Among the most striking geologic features on the surface of Arrokoth is the ensemble of large, broadly similarly sized mound-like features seen on the larger lobe.
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.
Resent studies question the evolution of the Moon magnetic field thanks to its demonstration of the existence of the inner core.
A similar solar storm today would be catastrophic for modern technological society—potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions of pounds.
Mercury has shrunk by7 km. Most of this happened long ago, but now we have evidence that it continues.
Now, using the James Webb Space Telescope, astronomers have found carbon on Europa’s surface, which likely originated in this ocean. The discovery signals a potentially habitable environment in the ocean of Europa.
NASA's OSIRIS-REx mission has delivered pieces of asteroid Bennu, which scientists hope will offer a window into the early era of the Solar System billions of years ago.
India’s Chandrayaan-3 moon rover has confirmed the presence of sulphur and detected several other elements on the lunar south pole, says the country’s space agency.
According to a new analysis of lunar craters, these pocks and divots that mar and characterize the lunar surface are too young for the long-term retention of ancient reservoirs of water ice.
The intrepid little spacecraft flew through a coronal mass ejection, helping scientists understand space weather.
Hawaian researchers discovered that high energy electrons in Earth's plasma sheet are contributing to weathering processes on the moon's surface and the electrons may have aided the formation of water on the lunar surface.
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.
India’s Chandrayaan-3 mission landed on the moon on Aug. 23. The Vikram lander operated for almost two weeks. After the start of lunar night the Vikram rover was put into sleep mode. Both the lander and rover have a chance of waking up again later.
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.
