Astronomers have increased the chances of a collision of Earth with an asteroid in 2182
Astronomers have increased the chances of a collision with Earth asteroid 1999 RQ36 in XXII century. According to new estimates, a celestial body could meet the Earth with the probability of one chance in a thousand. Details of how scientists determined the probability of collision, are shown in a press release, the Spanish Foundation for Science and Technology. Earlier report on the calculations of researchers was published in the journal Icarus.
Spanish researchers track the movement of asteroids, determined that 1999 RQ36 may meet with the Earth with the probability of one chance in a thousand, with approximately half of all likely accounts for 2182. In their calculations, researchers have used probabilistic models,

Sun rises on the probe SDO
Since its launch in February 2010, the recipe satellite SDO (
Solar Dynamics Observatory ) was performed in order to ensure that everything
worked properly. Fully operational, SDO observes today the Sun continuously
