First comet found with ocean-like water

This was the first time ocean-like water was detected in a comet. The results show that the amount of material out there that could have contributed to earth's oceans is perhaps larger than we thought. This is a new evidence supports the theory that comets delivered a significant portion of earth's oceans, which scientists believed formed about 8 million years after the planet itself. We always think our ocean came from comet, but we never have convincing evidence to support it. Now we have:)

By ocean-like water, I wonder if that means the comet was made of salt water?

Wow, I always knew that the Great Lakes formed from the melting of large, icy glaciers millions of years ago, but I never knew any theory about the formation of the oceans. If salt water really was detected in this comet, I'm convinced that the oceans did form from a comet-Earth collision many years ago. Very cool stuff.

It makes you think that since comets still have water on them, is there a possibility that small life exists in one of these comets

Does this mean that the comet is made of liquid water or solid ice water? If liquid water is it held together by its own gravity?

This is an awesome discovery. I never knew that the oceans were even thought to have been formed from comets. This evidence can be the first step to proving the theory that the Earth's oceans formed from a comet-Earth collision. I wonder how much water was actually in this one comet?

This discovery is great. This could be a path to find life outside of earth since liquid water is the ultimate source of life
