Scientists at Brown University have found evidence that the moon could contain more water than previously thought.

How they found it: Using images of the moon's surface, researchers measured the amount of water trapped in volcanic deposits across the surface of the moon by looking at sunlight reflected from the rocks.

"It's not much [water], maybe a couple hundreds parts per million, but the size of these deposits are huge, you have a lot of material to work with," Ralph Milliken, the lead author of the study, told Popular Science. "Theoretically, we could extract water from these deposits for human exploration."

Why it matters: If — and that is a big if right now — water on the moon could be extracted, it could be used as a pitstop on the way to Mars. Elon Musk suggested something similar recently in calling for a base for the moon.

The sudden uncertainty surrounding the future of the Affordable Care Act could be an enormous political liability for Republicans in key states come November.

Between the lines: Millions of people in crucial presidential and Senate battlegrounds would lose their health care coverage if the Supreme Court strikes down the law, as the Trump administration is urging it to.

The coronavirus is surging once again across the U.S., with cases rising in 22 states over the past week.

The big picture: There isn't one big event or sudden occurrence that explains this increase. We simply have never done a very good job containing the virus, despite losing 200,000 lives in just the past six months, and this is what that persistent failure looks like.
