Ever since the beginning of the Space Age, the inner planets and the Earth-Moon system have received the lion’s share of attention. That makes sense; it’s a whole lot easier to get to the Moon, or ...

The outer reaches of our Solar System continue to reveal a complex dynamical environment where the interplay of gravitational forces shapes the orbits of a myriad of distant bodies. Research in this ...

Could a lonely planet wander aimlessly through the restless galaxy change the subtle dance of gravity within our solar system? Astronomers have new cause to investigate. With powerful telescopic ...

Researchers have developed a novel technique to investigate the dynamics of the early Solar System by analyzing magnetites in meteorites utilizing the wave nature of electrons. Within meteorites, the ...

Spiral Galaxy from Kirkland et al. CREDIT Chris Kirkland and colleagues. A new study of zircon crystals from two of Earth’s oldest continents indicates that the formation of Earth’s continental crust ...

At the far edge of the Solar System, where the Sun’s influence thins into the dark between the stars, a pair of aging ...

The solar system and its place in the galaxy -- The origin of the solar system -- A history of solar system studies -- The Sun -- The solar wind -- Mercury -- Venus: atmosphere -- Venus: surface and ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

The solar system originated from a collapsing cloud of gas and dust approximately 4.5 billion years ago, with the Sun forming in the central region through nuclear fusion and the planets condensing ...
