Our galaxy, the Milky Way, is surrounded by many other small galaxies. Some of these include dwarf galaxies which are very small as compared to the Milky Way. In the past, these dwarf galaxies have been colliding with the Milky Way but because of its huge size Milky Way showed no significant change in its shape or behavior, so in short our galaxy is not likely to be destroyed by these small galaxies. The previous thoughts of colliding galaxies involved rip and tear motion but this actually happens if a big galaxy like the Andromeda collides with the Milky Way, only then havoc will be created. In fact, scientists think many satellite galaxies have already rammed into the Milky Way, though so far it has endured.

Earthlings! Get ready to pack your bags and leave… the planet! No, wait; leave the galaxy if you can!
Well NASA is planning to send another rover to Mars. This time it’s Mars Science Laboratory (MSL) which is due to launch in 2011. NASA has asked people to submit their names, which will be encoded in a microchip. This chip will be place on the rover which will be heading to the martian surface. So send your names to Mars for free .
