scientist from the University of Texas at Austin have analyse a strange depression on Mars that may be a honest bet for finding life .
The clinical depression caught the attention of the researchers because it look to be similar to “ ice cauldron ” on Earth . This is where a vent has erupted through an ice tack or glacier , creating a large funnel shape that narrows as you get deeper .
It ’s locate within the largest impact volcanic crater we know of in the Solar System , called the Hellas watershed , which is about 2,300 kilometer ( 1,400 knot ) across . And it was of fussy interest because of concentric anchor ring seen around its outside , grounds of volcanic activeness .
If confirmed as being formed by a vent , the depression would be of peculiar interest because it could be a chemical - rich environment well suited for sprightliness . A paper describing the latest finding was print in the journalIcarus .
" We were drawn to this site because it looked like it could host some of the key component for habitability – H2O , heat and nutrients , " lead author Joseph Levy from the University of Texas Institute for Geophysics say in astatement .
The Hellas depression was in reality one of two take by the researcher in images taken by the Mars Reconnaissance Orbiter ( MRO ) . Another , in a part called Galaxias Fossae , has a similar appearance . Two theories had been touted for their formation , either this “ internal-combustion engine cauldron ” mind that melted away surface ice , or an asteroid impact .
found on 3D models , the researchers now think the two formed in different ways . Galaxias Fossae was in all probability the solution of an impact , based on dust spread around the area , whereas the Hellas depression lacks such rubble – suggest at a volcanic origin .
Mars is thought to have been at its peak volcanic body process between 3.7 billion and 500 million age ago . We do n’t have any evidence for volcanic eruption today , although there aresome hintsit may still occur .
Nonetheless , if the Hellas Great Depression really was mould by a volcano , it could be a serious placement to reckon for sign of life . A combination of limpid water and chemical substance nutrients could make it a select fair game for future study .
