This is CBSI on the world. Behind the Black, Bob Zimmerman, after 15 years, takes us again to Mars, to the glaciers of Mars and revelations. Bob, the glaciers of Mars are a source of water. They'll be critical when and if we get there. Is there something unusual about them? Good

evening. Well, what's been discovered now, scientists that looked at five different areas of

Mars in the mid-latitudes in both the north and south hemispheres, and they found that in every

case, the data says that these glaciers are almost pure, pure water, covered by a thin cover of dust and debris

to protect them.

That just means, once again, Mars is not a desert like a Sahara.

It's a desert like Antarctica with lots of ice everywhere.

Above 30 degrees latitude, you basically have ice almost everywhere near surface ice,

and the glaciers are now pure water that's

what they they think and that's really significant for future colonization john and the the two

phenomena about baby solar system baby solar system what is unique about this okay so i have two

stories these are both about baby solar systems.

These are baby stars that are forming their solar systems.

In one case, astronomers detected the first evidence of gas condensing into molecular solids

in the protoplanetary disk where planets form.

This is essentially watching the gas and the dust form into minerals, molecules, as if they're beginning to form planets.

This is the beginning process of the solar system.

So that's kind of interesting.

And the second story is they detect, previous images from the very large telescope in Chile had discovered

a protoplanetary spiral disk around the baby star.

This is gas and material, once again, forming a solar system.

They used a different instrument on the very large telescope to look at that spiral disk
