Many mammals came perilously close to extinction when a massive asteroid hit the earth 66 million years ago, says a study, adding that if a few lucky species did not make it through then mammals may have gone the way of the dinosaurs.
To spread awareness and educate the world about asteroids, scientists recently announced "Asteroid Day". Along with it, a 100x Declaration was also released to protect the future of Earth from asteroid impacts .
Russian scientists plan to create a space observatory which can spot asteroids measuring over 50 metres at a distance of one astronomical unit and other space objects a decametre in size, similar to the Chelyabinsk meteorite, in the near Earth orbits.
A new NASA map has revealed that over 556 asteroids smashed into the atmosphere over a 20-year period between 1994 and 2013, suggesting that space rocks are slamming into the Earth's atmosphere at a higher rate than previously thought.

'Life on Earth' as we know it may be destroyed within a century. Scientists now believe that life on earth could get destroyed with impacts from around 400 asteroids between 2017 and 2113, as per a new data revealed by NASA.
A federal audit report said that the US space agency, NASA, does not have enough money for launching big rockets and that its new $12 billion rocket program may not be launched by the end of 2017 as planned.
Researchers have revealed that the centimeter-sized fragments and smaller particles that make up the regolith - the layer of loose, unconsolidated rock and dust - of small asteroids is formed by temperature cycling that breaks down rock in a process called thermal fatigue.
