Analysis of a meteorite that fell in Costa Rica shows that its parent body may resemble the asteroid Bennu.
Each solar cycle might seem like the same old story, but one thing has changed significantly since the previous solar maximum–our technology.
After an exciting encounter with asteroid Bennu, the OSIRIS-REx mission team looks forward to hitting pay dirt when a hefty sample of ancient planetesimal material is delivered to Earth next year.
Analysis of the Chassigny meteorite suggests the planet acquired most of its interior volatiles from meteorites, not from the solar nebula.
The Gaia mission’s asteroid survey will help dig deeper into the solar system’s rocky history.
New simulations suggest that subsurface oceans on icy moons with small natural Rossby numbers may be dominated by rotational effects.
Geologically young regions of Pluto’s southern hemisphere were likely resurfaced by cryovolcanism, data from the New Horizons spacecraft reveal.
A new algorithm suggests that only a small fraction of meteorites present on the White Continent’s surface have been recovered to date.
Spectral data and modeling suggest that volatile-rich main-belt asteroids initially formed at much greater distances from the Sun (>10 AU).
