These glass depositions might just provide an insight intoancient signs of lifeon the Red planet.
Earlier astronomical studies have shown that it is possible to preserve ancientbio-signaturesin animpact glass.
Before this paper, no one had been able to definitively detect them on the Martian surface.
However, the impact glass is a bit different as it does not have any particular strong spectral signal.
But Kevin found a way to tease that signal out.
He then measured the spectral signal using this glass.
With this technique the duo were able to detect even smaller amounts of deposits around several crater central peaks.
The duo researchers said: We think these could be interesting targets for future exploration.
In fact, we have a particular spot in mind.
That makes this a pretty compelling place to go look around, and possibly return a sample.
Readers can get complete details of this research which has been published online in the journalGeology.
