The possibility of life on Mars continues to excite scientists, this time because of glass sand discovered on the Red Planet.
Researchers say the newly discovered glass dune fields may lead to chemically rich water that would be ideal for supporting life on Mars. They say the dunes are spread across almost a third of the planet, and were likely formed because of interactions between magma and ice or water.
The researchers say such interactions could create the perfect environments for microbial life.
"The only way to create an extensive glassy deposit like that is through explosive volcanism," Briony Horgan, a scientist at Arizona State University involved in the research, told Astrobiology Magazine . "This is the first direct evidence on Mars for explosive volcanism on a planetary scale."
The finding came from research into possible interactions of lava flows and floods of water in the Elysium volcanic province of Mars, according to a news release from ASU.

Moons covered in glass too....fasinating, thank you!
This thread won't gain attention because there's no mention of inpediment doom! Lol
Volcanoes in Iceland erupt underneath glaciers, and the interactions between water from the glaciers and lava from the volcanoes create incredibly explosive eruptions. The lava fragments, and transforms into particles of glass. Huge sand dunes and sand plain fields form that consist of 50 to 70 percent glass. Horgan and Bell hypothesize that the same process occurred during periods of volcanism on Mars.

Glass dunes? Covering a freaking third of the planet? The report said they are on average 30 meters wide, how the hell is this the first time we're hearing of this?
There are already reports of a team of scientists reviewing the evidence from the Viking 1 probe in 1976 that say they have already proven that there is life on Mars. Viking probe, 1976
So, I find most of these "announcements" are well known information that NASA and their ilk have been hiding from us for many years.

The dunes are not made of glass. They have a high percentage of glass particles (along with other stuff).
The article has it backwards, the dunes do not lead to chemically rich water. The glass particles do not provide a perfect environment for microbial life. The conditions under which they formed (something like 2 billion years ago) indicate that there may have been liquid water available at the time (lava + water = "chemically rich water"). In other words, at the time the glass was formed conditions may have been good for the existence of life.

I bet Mars is very fun for geologists or people of that ilk. (volcanologists?)
