The significantly weaker magnetic field, smaller magnetosphere, and much faster timescale of processes around Mercury, when compared with Earth, enable...
During solar storms, the Sun expels large amounts of energetic particles that can react with the atmosphere of Earth and produce cosmogenic isotopes such...
The solar wind, comprised of solar particles largely made of hydrogen ions, created water on the surface of dust grains carried on asteroids that smashed...
The long-period comet C/2019 Y4 (ATLAS) fragmented during its perihelion in April 2020. About two months later, ESA’s Solar Orbiter observed the dusty...
Using data from NASA’s Parker Solar Probe, a team of solar physicists calculated the distribution of electrons within the electric field of the Sun;...
Astronomers using NASA’s Interstellar Boundary Explorer (IBEX) satellite have mapped the boundary of the heliosphere, the vast region of space surrounding...
Planetary scientists using data from the Ultraviolet Spectrograph (UVS) aboard NASA’s Juno spacecraft have discovered expanding emission circles of ultraviolet...
Dawn storms consist of short-lived but intense brightening and broadening of Jupiter’s main auroral oval near where the atmosphere emerges from darkness...
Solar storms strip a planet’s atmosphere over time, and only a strong magnetosphere would be able to provide maximum protection. Lunar samples gathered...
ESA’s Solar Orbiter spacecraft, in collaboration with NASA, launched in February 2020 on its mission to study to Sun and it began collecting science...
Using data from several instruments aboard ESA’s Rosetta mission, researchers have found evidence of far-ultraviolet aurora on comet 67P/Churyumov-Gerasimenko.
This...
Astronomers using NASA’s HERSCHEL (Helium Resonance Scattering in the Corona and Heliosphere) sounding rocket have obtained global images of the helium...
Solar Orbiter, a space mission of international collaboration between ESA and NASA, made its first close approach to the Sun in mid-June and captured unique...
NASA’s Parker Solar Probe has captured unique images of comet C/2020 F3 (NEOWISE) and its two tails.
This image from the WISPR instrument on board NASA’s...
Using five years of magnetic field data obtained by NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft, a team of scientists has created...
New images from the NASA/ESA Hubble Space Telescope of the long-period comet C/2019 Y4 (ATLAS), taken on April 20 and 23, 2020, provide the sharpest views...
Using the NASA/ESA Hubble Space Telescope and several ground-based telescopes, astronomers have been able to watch the long-period comet C/2019 Y4 (ATLAS)...
In 2011, NASA’s MESSENGER orbiter detected signals typical of glacial ice near the poles on Mercury. The ice was dingy and lurked in permanent shadows...
Solar Orbiter, a new collaborative mission between ESA and NASA to study our Sun, successfully launched on an Atlas V 411 rocket from Cape Canaveral Air...
New observations from NASA’s Parker Solar Probe show how Sun’s plasma that is released after a solar flare can accelerate and pile up solar energetic...
