Warped meteor showers hit Earth at all angles

Some meteor showers persist for weeks and months, even though Earth sweeps a big arc around the Sun during that time. The meteors arrive from a slightly different direction each day, which is a clue to why these showers last ...

Mars' ionosphere shaped by crustal magnetic fields

Scattered pockets of magnetism across the surface of Mars have a significant influence on the planet's upper atmosphere, according to observations from ESA's Mars Express. Understanding these effects may be crucial for ensuring ...

Mars' surface revealed in unprecedented detail

The surface of Mars – including the location of Beagle-2 – has been shown in unprecedented detail by UCL scientists using a revolutionary image stacking and matching technique.

Asteroids found to be the moon's main 'water supply'

Water reserves found on the moon are the result of asteroids acting as "delivery vehicles" and not of falling comets as was previously thought. Using computer simulation, scientists from MIPT and the RAS Geosphere Dynamics ...

Airless space weathering duplicated in lab environment

Using laboratory instruments typically used to make semiconductor devices, space weathering of airless bodies in the Solar System has been simulated, allowing researchers to better determine the ages of their surfaces, states ...
