Scientists suggest that at least two huge tsunamis once swept across the Red Planet, triggered by large impacts.

Dozens of space scientists are desperately scouring the skies after losing track of a quarter-of-a-billion-dollar Japanese satellite that was sent to study black holes.

The formal test programme has begun on the technologies required to detect gravitational waves in space.

For the first time, scientists have detected tiny, rhythmic distortions in space and time- gravitational waves- predicted by Einstein 100 years ago.

A new map of the dwarf planet revealed that water ice is surprisingly abundant on Pluto's surface.

Chinese lunar rover Yutu has discovered new volcanic rocks on Moon unlike those returned by Apollo and Luna missions, offering tantalising clues to the period of lunar volcanism.

The Russian space agency says that its out-of-control spacecraft has burnt up as it re-entered the Earth's atmosphere.

Mars has thousands of glaciers buried beneath its dusty surface, enough frozen water to blanket the planet with a 3.6-foot(1.1- meter) thick layer of ice, scientists say.

Two most audacious space missions- Solar Orbiter and Solar Probe Plus, are currently in development and will venture inside the orbit of Mercury to study the Sun
