Possible caves in planet Mars

Scientific that study the images of the ship Odyssey of NASA they have detected what you/they seem to be 7 caves in the surface of Mars.

This notice has just been announced in BBC News. The scientists have reached this conclusion due to the vertical reflection of the solar light in the flanks of the volcano Arsia Mons that indicate the appearance of cavities in the surface. The particulars of the discovery showed up in the Conference of Lunar and Planetary Sciences in Houston, Texas. Translated of the notice:

The authors say that the possible discovery of caves in the Red Planet is important. The caves could be the natural only structures able to protect primitive forms of life of micrometoros, radiation UV, solar ionospheric storms and particles high-energy that bombard the surface of the planet. The entries of these caves have between 100 and 252 width meters. Since in most one cannot observe the bottom, minimum depths are only known, from among 73 and 96 meters under the surface. However, you are calculated that the caves would have a perpendicular depth of up to 130 meters or more.

The measured temperatures as much in the surface as inside the supposed caves provide bigger information in this respect:

The data of temperature THEMIS backups this idea. During the day, one of the caves (to the one that "Annie" has called you you/he/she is warmer than the other and colder that the exposed areas to the solar light. The night temperature is warmer than in almost any other field. Glen Cushing, co-author and scientific of USGS in Flagstaff, Arizona, said that this is exactly what should happen if this structure was a cave. "Anything eats this you had been seen before in Mars", you said.

The scientists refer to the probable caves like the "seven sisters", to those that have allocated names to distinguish them: Dena, Chloe, Wendy, Annie, Abbey, Nicki and Jeanne.
This is at the moment the available information. In a future I will upgrade this entry. Meanwhile, they can observe the surface of the volcano Arsia Mons in Google Mars, or in the web page of the system THEMIS.
