Why is Mars red?
April 2nd, 2011 - 2:38 pm ICT by ANIWashington, Apr 2 (ANI): Ever wondered why Mars is red? According to a scientist, about 180 million years ago, a planet-shattering yet naturally occurring nuclear reaction may have wiped out everything on Mars, sending a shockwave that turned the planet into dry sand.
“The Martian surface is covered with a thin layer of radioactive substances including uranium, thorium and radioactive potassium — and this pattern radiates from a hot spot [on Mars],” Dr. John Brandenburg, a senior propulsion scientist at Orbital Technologies Corp, told Fox News.
“A nuclear explosion could have sent debris all around the planet.
“Maps of gamma rays on Mars show a big red spot that seems like a radiating debris pattern … on the opposite side of the planet there is another red spot,” he added.
According to Brandenburg, the natural explosion, the equivalent of 1 million one-megaton hydrogen bombs, occurred in the northern Mare Acidalium region of Mars where there is a heavy concentration of radioactivity.
This explosion filled the Martian atmosphere with radio-isotopes as well, which are seen in recent gamma ray spectrometry data taken by NASA, he said.
The radioactivity also explains why the planet looks red. (ANI)
