The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment….
Somewhere between Earth’s creation and where we are today, scientists have demonstrated that some early life forms existed just fine without any oxygen….
A group of researchers from the National Astronomical Observatory of Japan (NAOJ), the University of Tokyo, and the Astrobiology Center among others has observed the transit of a potentially Earth-like extrasolar planet known as K2-3d using the MuSCAT instrument on…
We use a simple organism lifecycle model to explore the viability of an atmospheric habitable zone (AHZ), with temperatures that could support Earth-centric life, which sits above an environment that does not support life….
A new study is the first to show that living organisms can be persuaded to make silicon-carbon bonds–something only chemists had done before. Scientists at Caltech “bred” a bacterial protein to have the ability to make the man-made bonds, a…
One of the open questions in astrochemistry is how complex organic and prebiotic molecules are formed….
The possible meteorite parent body origin of Earth’s pregenetic nucleobases is substantiated by the guanine (G), adenine (A) and uracil (U) measured in various meteorites….
Approximately 60 percent of all stars in the solar neighbourhood (up to 80 percent in our Milky Way) are members of binary or multiple star systems. This fact led to the speculations that many more planets may exist in binary…
The formation pathways of different types of organic molecules in protostellar envelopes and other regions of star formation are subjects of intense current interest….
The Kepler era of exoplanetary discovery has presented the Astronomical community with a cornucopia of planetary systems very different from the one which we inhabit….
