I just read the piece at the link below entitled "Study: Life might survive, and thrive, in a hydrogen world."
I'd been thinking on similar lines recently, on different atmospheres with early life, but I was considering anoxogenic bacteria whose byproduct is sulfur instead of molecular oxygen. ¿Had life evolved on Venus could its sulfuric clouds be the signature byproduct of such life with no branches ever evolving to produce the equivalent of Earth's Great…Continue
Exactly 100 years ago tomorrow, the subject on whether this Universe is larger than the Milky Way Galaxy was brought up publicly at an event sponsored by the National Academy of Sciences, known as The Great Debate. Until then the Milky Way was thought to be this Universe. Conference at the NAS http://www.nasonline.org/about-nas/events/annual-meeting/nas157/

Amid fresher's life, every one of them faces with decent variety of assessments inside the grounds group. It isn't outsider, on the off chance that somebody idolizes pizza and abhor for soup. We should get the considering circumstance for instance.

Paleontologists from Manchester University found 205-million year-old jaw bone of a prehistoric reptile belongs to 'one of the largest animals ever' (bigger than the blue whale). It's the jaw bone of giant Ichthyosaur. Now, when dinosaurs were hip-hopping on the land few of their cousins jumped into the sea and became the aquatic reptiles. Those few cousins appeared like a huge fish with limbs modified into flippers and…Continue

In the search for intelligent life, it is very possible for us to encounter an artificial intelligence created by a species more advanced than us. A sufficiently advanced form of AI could be indistinguishable from natural intelligence as we know it. The question of intelligence questions what we think is true of intelligent and sentient life forms. How would we distinguish between the two, and if we encounter an AI vs another species, do we accept them as a representative of their creators?…Continue
Lately, there has been more peer discussion about how we go about searching for life off planet earth. A few places within our solar system were identified as good targets to begin the search for life, among them: the Moon, Mars, Titan and Enceladus. We need to begin the search with patience.
Our Moon is the closest celestial body to us. The LRO is currently taking pictures, but a new mission to establish an out post on the moon should begin. Why not get very good about getting to…Continue

Based on recent readings, especially from Christopher McKay in How to Search for Life on Other Worlds, I’ve come to believe that life only needs the right combination of three main requirements: a main solvent to host chemical reactions (ours on Earth being water), a mixture of common building-block elements (Carbon, Hydrogen, Oxygen, Phosphorus, Nitrogen, Sulfur are examples of this), and enough energy to cause chemical reactions. In Astrobiology lecture, we have discussed life…Continue

Everyone have there own opinion about life. Some believe it was created by some supernatural powers /God. And some believe that it was not created, it was an accidental process that is still in existence.
Does all this really makes sense? We don't have proof, that how life begin on Earth? Did it really begin here or, was seeded on Earth as in the Theory of Panspermia. Maybe life began here on Earth by the…Continue

Before we discuss actual examples of unearthly life, it would be prudent to set forth a solid definition of what life actually entails. For my own worldbuilding purposes, I have composed a simple set of requirements for something to be defined as alive:
> Inertia-independent reaction to stimulus, however slight and regardless of speed.
> The independent production/collection and storage of energy within the entity in question for biological…
