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.
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.
According to an analysis of grains collected from asteroid Ryugu, at least part of the carbon-rich rock started its life much farther from the Sun before ending up in the asteroid belt and then, ultimately, at roughly Earth's distance from the Sun.
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.
