Spitzer Space Telescope has established an evidence of a high-speed collision between two burgeoning planets around a young star.
NASA's astronomers say that two rocky bodies, one as least as big as our moon and the other at least as big as Mercury, slammed into each other with a great speed within the last few thousand years or so but, not long ago by cosmic standards. This impact had destroyed the smaller body, vaporizing the huge amounts of rock and flinging massive plumes of hot lava into space.
Spitzer's infrared detectors were able to lift up the signatures of the vaporized rock, along with pieces of refrozen lava, called tektites.
