A team of scientists affiliated with several institutions in the U.S. has tested a theory created to explain the amount of oxygen in the atmosphere of Callisto, one of Jupiter's moons, and has found that it falls short. In ...
A team of planetary scientists at Arizona State University has found evidence that the multitude of bright flashes in Venus' atmosphere may be due to meteors passing through, not lightning strikes. In their paper published ...
A team of space scientists at the Planetary Science Institute, working with colleagues from the Chinese Academy of Sciences, Shenzhen University and the University of Aberdeen, has used data from China's Chang'E-4 rover to ...
The origin of Mercury, the closest planet to the sun, is mysterious in many ways. It has a metallic core, like Earth, but its core makes up a much larger fraction of its volume—85% compared to 15% for Earth.
