The Canadian government unveiled Wednesday its long awaited national space strategy, focusing on artificial intelligence, deep-space robotic systems, Earth-observation capabilities and searching for new ventures with the European Space Agency.
The proposed accelerator would help physicists study Higgs boson particles in detail
Collisions between bodies in our Solar System produce impact craters on large objects at a rate that depends on the population of impacting small bodies. By mapping the scars of ancient impacts on the surfaces of Pluto and its moon Charon, planetary researchers have discovered a surprising lack of very small objects (from 300 feet to 1 mile, or 91 m to 1.6 km, in diameter) in the Kuiper Belt.

“This funding effort is in service to every citizen of every nation now convinced the world should not wait one more day for confirmation we are not alone is this universe. For 70 years this truth has been embargoed by your government. After 20 years of engagement of the issue, I know this embargo can end soon with your help.” Stephen Basset, Executive Director
Researchers have proposed a new idea that may explain why some Antarctic icebergs are tinged emerald green rather than the normal blue, potentially solving a decades-long scientific mystery.
A popular theme in the movies is that of an incoming asteroid that could extinguish life on the planet, and our heroes are launched into space to blow it up. But incoming asteroids may be harder to break than scientists previously thought, finds a Johns Hopkins study that used a new understanding of rock fracture and a new computer modeling method to simulate asteroid collisions.
In what sounds like the opening scene of a horror movie, British cave enthusiasts have discovered hundreds of centuries-old protective marks and ritualistic drawings designed to capture, trap and repel evil forces.
Observations by ESA’s Mars Express orbiter show evidence of an ancient planet-wide groundwater system on the Red Planet.
