Icarus is a premier scientific journal dedicated to the field of planetary science. It is published under the auspices of the American Astronomical Society s Division for Planetary Sciences (DPS). The longtime publisher was Academic Press, which is now part of Elsevier. The journal contains articles discussing the results of new research on astronomy, geology, meteorology, physics, chemistry, biology, and other scientific aspects of the Solar System or extrasolar systems. The journal was founded in 1962, and became affiliated with the DPS in 1974. The late Carl Sagan served as editor of the journal from 1968 to 1979. He was succeeded by Joseph A. Burns (1980–1997) and Philip D. Nicholson (1998–present). The journal is named for the mythical Icarus, and the frontispiece of every issue contains an extended quotation from Sir Arthur Eddington equating Icarus adventurousness with the scientific investigator who "strains his theories to the breaking-point till the weak joints gape."
HiRISE Mars camera reveals hundreds of impacts each year
Scientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 ...

Lunar impacts created seas of molten rock, research shows
Early in the Moon's history an ocean of molten rock covered its entire surface. As that lunar magma ocean cooled over millions of years, it differentiated to form the Moon's crust and mantle. But according ...

Observed changes to Martian surface caused by seasonal thawing of carbon dioxide ice
(Phys.org)—Spring is a dynamic season on the dunes surrounding Mars' north pole. When frozen carbon dioxide, or dry ice, deposited as a winter ice cap on Mars sublimates – changes directly from a solid ...

Vesta: Large impacts of asteroids may have transferred carbonaceous material to the protoplanet and inner solar system
The protoplanet Vesta has been witness to an eventful past: images taken by the framing camera onboard NASA's space probe Dawn show two enormous craters in the southern hemisphere. The images were obtained ...

Giant impact scenario may explain the unusual moons of Saturn
Among the oddities of the outer solar system are the middle-sized moons of Saturn, a half-dozen icy bodies dwarfed by Saturn's massive moon Titan. According to a new model for the origin of the Saturn system, ...

Stagnant interiors suppress chances of super-Earths supporting life
(Phys.org)—Exoplanet hunters estimate that there could be billions of super-Earths—planets with a mass of up to ten times that of Earth—orbiting stars in the Milky Way alone. But do super-Earths really ...

Mars's dramatic climate variations are driven by the Sun
On Mars's poles there are ice caps of ice and dust with layers that reflect to past climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars's north ...

Triton: A subsurface ocean?
Neptune's largest moon Triton is most likely a captured Kuiper Belt Object. The capture of icy Triton and the subsequent taming of its orbit likely led to the formation of a subsurface ocean through tidal ...

New research eclipses existing theories on the Moon formation
The Moon is believed to have formed from a collision, 4.5 billion years ago, between Earth and an impactor the size of Mars, known as "Theia." Over the past decades scientists have simulated this process and ...
