It’s long been a question. As to how Mars turned red may, a new theory emerges challenging the previous speculation. See video of the planet nearest to the Earth and find out the latest hypothesis as to why it may have its signature color.


The previous theory was that the characteristic color of the planet was the result of rocks rusted by water. Now, according to the L.A. Times citing research from the Mars Simulation Laboratory at the University of Aarhus in Denmark reveals how scientists produced red dust in glass flasks by combining and shaking up sand with magnetite, an iron oxide that is present in rocks on Mars. The findings were presented at European Planetary Science Congress in Potsdam, Germany.

Regarding the new findings Jonathan Merrison said in a statement:

“Subsequent analysis of the flask material and dust has shown that the magnetite was transformed into the red mineral hematite through a completely mechanical process without the presence of water.”

Responding to the research, Mars scientist Matthew P. Golombek from the Jet Propulsion Laboratory in La CaƱada Flintridge is quoted as saying it is:

“an interesting hypothesis. I would say our knowledge of what produced the dust on Mars has always been pretty poor. I don’t think we know whether the dust is ancient or new. This is one more very interesting idea.”

New Scientist quotes Joel Hurowitz of NASA’s Jet Propulsion Laboratory who said the study was “interesting” but needs more research.

The publication reveals more specifics of the scientists’ methodology, noting that the glass flask was tumbled for several months as the substance became redder, with the magnetite changed into haematite. It is believed that a similar process may have occurred on Mars, over the course of possibly thousands of years.

And, as the mysterious planet continues to fascinate the public and the scientists, that is the latest buzz on how possibly Mars turned red.
