Mars hosts various auroral processes despite the planet’s tenuous atmosphere and lack of a global magnetic field. To date, all aurora observations have...
The Sun rarely produced extreme solar particle events, orders of magnitude stronger than everything directly observed. Their enormous power can greatly...
When NASA’s Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists’ first close glimpse of this ice-giant planet. Alongside the discovery...
This milestone promises to enhance our understanding of the Sun’s atmosphere and how its changing conditions lead to impacts on our technology-dependent...
Mars’ water history is fundamental to understanding an evolution of Earth-like planets. Water escapes to space as atoms, and hydrogen (H) atoms escape...
Two-dimensional (2D) aurora images with full spectrum have been captured by scientists in Japan using the newly-developed hyperspectral camera for auroral...
Cold, dense clouds in the interstellar medium of our Milky Way Galaxy are around four-five orders of magnitude denser than their diffuse counterparts....
The Negative Ions at the Lunar Surface (NILS) instrument onboard China’s Chang’e-6 probe has detected negative ions on the surface of the Moon. These...
In August 2021, the ESA/JAXA Mercury-bound BepiColombo spacecraft performed its second flyby of Venus and provided a short-lived observation of its induced...
Earth’s magnetic field is occasionally but regularly impacted by bursts of energy from the Sun (space weather), such as coronal mass ejections. Birds...
In new research, scientists from the University of Leeds and elsewhere measured radiocarbon levels in ancient trees preserved within the eroded banks of...
Planetary scientists from the University of Hawaii and elsewhere suggest that although they have confirmed the importance of the solar wind as a major...
Extreme ultraviolet images of the Sun obtained by the Extreme Ultraviolet Imager (EUI) instrument onboard the ESA/NASA Solar Orbiter spacecraft have revealed...
NASA’s Parker Solar Probe has flown close enough to the Sun to detect the fine structure of the solar wind close to where it is generated at the solar...
Life most likely started during the Hadean Eon (4.5 to 4 billion years ago). However, the environmental conditions which contributed to the complexity...
Scientists from China and the United States have analyzed the impact glass beads from a lunar soil sample returned by China’s Chang’e-5 mission.
Asteroid...
Solar switchbacks are sudden, large radial deflections of the solar wind magnetic field, previously revealed in interplanetary space by NASA spacecraft.
This...
Even though Mars does not have a global magnetic field like the Earth, it still possesses multiple kinds of aurora. One of these is proton aurora, which...
