A new extrasolar system planet can be added to a handful of fellow exoplanets which could theoretically support life, the European Southern Observatory said Wednesday.

An unmanned cargo ship packed with 7,400 pounds (3,350 kilograms) of food and supplies for the astronauts living at the International Space Station blasted off Sunday from Wallops Island, Virginia.

Orbital ATK's barrel-shaped Cygnus cargo ship launched atop an Antares rocket at 7:19 am (1219 GMT), a day after a last-second delay due to an unexpected aircraft in the area.

Scientists have found a hidden chamber in Egypt's Great Pyramid of Giza, the first such discovery in the structure since the 19th century and one likely to spark a new surge of interest in the pharaohs.

In an article published in the journal Nature on Thursday, an international team said the 30-meter (yard) void deep within the pyramid is situated above the structure's Grand Gallery, and has a similar cross-section. The purpose of the chamber is unclear, and it's not yet known whether it was built with a function in mind.

Sixty years after Laika the dog became the first living creature to go into orbit, animals are still being sent into space -- though these days much smaller creatures are going up.

Since early September, the denizens of this normally hushed burg in central France have been serenaded by an industrial drill poking holes around town and pulling up cylinders of rock.

That's because Rochechouart, population 3,800, and its medieval castle are built on top of an astrobleme. 

A "monster" planet, which should in theory not exist, has been discovered orbiting a faint dwarf star far, far away, surprised astronomers said Tuesday.

It may look like an ordinary door mat, but its creators insist the conceptual art piece could encourage alien life to visit Earth -- and help create a new kind of space archeology.

A note that Albert Einstein gave to a courier in Tokyo, briefly describing his theory on happy living, has surfaced after 95 years and is up for auction in Jerusalem.

Lake Baikal is undergoing its gravest crisis in recent history, experts say, as the government bans the catching of a signature fish that has lived in the world's deepest lake for centuries but is now under threat.

Holding one-fifth of the world's unfrozen fresh water, Baikal in Russia's Siberia is a natural wonder of "exceptional value to evolutionary science" meriting its listing as a World Heritage Site by UNESCO.

Scientists have for the first time witnessed the crash of two ultra-dense neutron stars, cataclysmic events now known to have generated at least half the gold in the Universe, excited research teams revealed Monday.

Shockwaves and light flashes emitted by the cosmic fireball traveled some 130 million light-years to be captured by Earthly detectors on August 17, they revealed at simultaneous press conferences around the globe as a dozen science papers were published in top academic journals.
