“Asteroid Quakes” – Mars is shaking up NEOs too
Scientists have long observed that the surfaces of most asteroids appear redder than meteorites. In 2010, a professor of planetary sciences at MIT, Richard Binzel, offered an explanation. Cosmic radiation changes the chemical nature of asteroid surface turning them red over time while Earth’s gravitational effect on asteroids is causing “asteroid quakes” that changes the surface of asteroids. This is consequently referred to as “refreshed” asteroids. In a recently published paper, scientists found that planet
NEOShield at DoDDS-Europe STEMposium 2013
On 18th November, NEOShield team member, Mr. Noah Saks from Astrium, shared with a group of high school students attending the annual STEMposium about how the NEOShield project is working to protect the Earth from a collision with a near-Earth object. By the invitation of the DoDDS-Europe, Noah’s riveting presentation (and occasional pop quiz) kept the 113 students (and teachers too!) on the edge of their seats.
Freak Asteroid has Six Tails
Resembling more like a lawn sprinkler or a badminton shuttlecock, asteroid P/2013 P5 projects bizarre characteristics. While normal asteroids appear as tiny points of light, this asteroid has six comet-like tails of dust and appears to be in the process of breaking up.
First spotted in August, astronomers have been scratching their heads trying to find an adequate explanation for the mysterious appearance of the fuzzy-like P/2013 P5 asteroid. Its multiple tails were first discovered
Chelyabinsk Asteroid: 19 metres, 12 000 tonnes
The asteroid that smashed into the city of Chelyabinsk measured 19 metres in diameter before exploding into small pieces between the altitudes of around 45 and 30 kilometres with the energy equivalent to several dozens of Hiroshima atomic bombs.
After analysing video and audio footage and meteorite fragments recovered from the incident that occured on February 15, 2013, a scientist from Czech Republic, Jiri Borovicka from the Academy of Sciences, estimated that the asteroid may
