For the same process to happen on other planets, first principles apply there as well. This radically reduces the probability of a comparable upstart elsewhere in the universe, whereas further evolution along the same line, resulting after a few billion years in a humanlike, intelligent being ...
So far, we have not found life on other planets, but the search continues. Planetary scientists and astrobiologists are using sophisticated instruments in space and on Earth to find planets with the right properties and the right location around their stars where life could exist. For carbon...
A new study conducted by American scientists found that there may be so-called "autocatalytic" chemical reactions on many planets, which can use various chemical elements other than carbon to create life forms completely different...
has a half-life of 5780 years and is used in archaeo logical investigations to date artifacts and ancient documents. Other uses of carbon depend on its form. For example, diamonds for jewels and abrasives,graphite for lubricants, activated carbon to absorb color and gases, and wood carbon for...
(ATP), the most important energy-transfer molecule in all living cells.[89] Norman Horowitz, head of the Mariner and Viking missions to Mars (1965-1976), considered that the unique characteristics of carbon made it unlikely that any other element could replace carbon, even on another planet,...
Corn cob is a rich biomass resource, and many studies have been conducted on its various applications. Health effects of carbon Nov 8, 2019 Carbon is unique in its chemical properties because it forms a number of components superior than the total addition of all the other elements in combinat...
The XO-2 system has a transiting hot Jupiter orbiting one binary component but not the other, allowing us to probe the potential effects planet formation might have on the host star composition. Additionally, with multiple observations of its atmosphere the transiting exoplanet XO-2b lends itself...
It is currently popular to assume that most material in the Earth and other planets was ejected from the already formed Sun, as suggested by Laplace. However, radial ejection of such proto-planetary matter cannot produce our Solar System, in which the planets have more angular momentum than ...

Rocky planets are more likely than gas giants to form around low-mass stars, making them the most common planets around the most common stars in our galaxy. Little is known about the chemistry of such worlds, which may be similar to or very different from Earth. By studying the disks from...
