[This study] confirms that gezegde

en [This study] confirms that the water for life on Earth could have come from comets.

en The beauty of comets is that they are important to us. We probably would not be here were it not for comets. Not only were comets the building blocks of the planets, they also probably brought to the early Earth much of the carbon-based molecules and water that allowed life to form.

en They are very small rocks, but they are rocks nonetheless. And what do these minerals tell us about how these grains form? We think that much of the Earth's water and organics ... perhaps came from comets. So what will these samples tell us about basically where our atoms and molecules came from and then how they were delivered to Earth and in what amount?

en Venus was born with the same sorts of constituents as Earth, which means there was some water in the environment. Some more probably came in from comets.

en It's like looking at our great, great grandparents. Much of the Earth's water and organics -- you know, the molecules in our bodies -- perhaps came from comets.

en NASA is interested in what conditions to look for on other planets that might lead to the arrival of life. What are the processes? Using earth as our most detailed study site, what are the necessary steps a planet needs to go through to enable complex animal life to arise? If oxygen is the metabolic pathway, then we need to know what conditions have to allow for that to happen. The geologic record provides us with a record of these steps that occurred on Earth.

en Life on Earth was not a cosmic fluke but part of a broad imperative. Mars is a lot like Earth. And billions of years ago it had some kind of atmosphere and huge quantities of flowing water.
