Surfaces of carbonaceous asteroids (C-complex) have shown diverse contrasting spectral variations, which may be related to space weathering.
Sulfur and chlorine isotopes in the atmosphere of Jupiter’s moon Io indicate that it has been volcanically active for the entire 4.57 billion-year history of the Solar System, according to […]
We use 1.4-4.6 micron multi-band photometry of the small inner Uranian and Neptunian satellites obtained with the James Webb Space Telescope’s near-infrared imager NIRCam to characterize their surface compositions.
Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth – and it could help assess which other […]
Life is complicated. What is true for our everyday existence also holds for the many complex processes that take place inside cells. Proteins constantly have to be synthesized, cell walls […]
Scientists outside of NASA’s OSIRIS-REx team are getting their first close look at the asteroid Bennu samples available for independent research just six months after their delivery to Earth.
Workshop Dates and Location The Second Workshop on Terrestrial Analogs for Planetary Exploration is scheduled for August 12–14, 2024, at the High Country Conference Center in Flagstaff, Arizona with virtual participation available.
All cometary nuclei that formed in the early Solar System incorporated radionuclides and therefore were subject to internal radiogenic heating. Previous work predicts that if comets have a pebble-pile structure […]
The ice-encrusted oceans of some of the moons orbiting Saturn and Jupiter are leading candidates in the search for extraterrestrial life. A new lab-based study led by the University of […]
Scientists believe that planetary systems like our solar system contain more rocky objects than gas-rich ones. Around our sun, these include the inner planets – Mercury, Venus, Earth and Mars […]
