Overall, Mars looks like a good candidate for past life. Water, carbon, and energy were all present in useful amounts. If life arises quickly wherever resources allow, then Mars probably had life once. Unfortunately we have no way to assess how common the origin of life might be. This is...

Little mixing occurs between inshore and offshore waters, and a significant portion of inshore water originates from runoff (Spain et al., 1976). Finally, thermal differences between the inshore and offshore regions lessen to the point where stratification of the whole basin occurs (Rodgers, ...

(XES) is split into two components where the intensities show dependence on temperature30,31and on adding NaCl32. Here, again there is no broadening or major shift in the two spectral components, only intensity changes. The origin of the split has been discussed as due to two different ...
This opens up many possibilities for how organic matter may be passed from one host to another in space, she said. "Everything leads to the conclusion that the origin of life is really possible elsewhere," Chan added.
Based on characteristics of the investigated LTDs and the evaporitic origin of the rocks forming the LTDs, and after discarding other possible origins (discussed above), these morphologies were interpreted as karst depressions, specifically dolines of polygenetic origin (Ford and Williams, 2007). ...

Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. Where those designations appear in this book, and Addison-Wesley was aware of a trademark claim, the designations have been printed with initial capital letters or in ...
Carbonaceous chondrites are thought to be among the oldest objects in the solar system and are rich in water and organic matter. Scientists believe that they are probably related to the origin of life on Earth. If a carbonaceous chondrite hits the moon, some of the water it was carrying cou...
