The existence of ample amounts of hydrogen in the subsurface ocean of Enceladus indicates that microbes--if any exist there--could use it to obtain energy by mixing with carbon dioxide dissolved in water. This particular chemical reaction, termed methanogenesis, because it manufactures methane as a byproduct, may have been of critical importance in the emergence of life on our planet.
Earth's Moon Reveals An Ancient Secret. Many astronomers think that during an ancient era, termed the Late Heavy Bombardment, our young Moon was violently battered by a marauding multitude of invading asteroids that crashed onto its newly formed surface. This attack of pelting objects from space occurred about 4 billion years ago, and the shower of crashing asteroids excavated impact craters, and also slashed open deep fissures, in the lunar crust. This sustained shower of merciless impacts increased lunar porosity, and opened up an intertwining network of large seams under the Moon's surface.
I found that this was true with most fish species and the activity level of fish is largely due to what the weather and moon are doing at the time that you go fishing. In other words I discovered that I could use the weather and moon to my advantage when I was fishing. I began to think back to the times that I had experienced amazing days fishing. The kind of days where it seemed as if no matter what I did, I caught fish, and not only did I catch fish but those fish tended to be larger than "average". Have you ever experienced this kind of day while fishing?
