NASA’s Kepler mission found evidence of several potentially habitable exoplanets, raising the possibility that life may have evolved independently outside of our solar system. If NASA found a novel lifeform, we would expect it to use energy molecules based on similar principles as lifeforms on Earth. The organism would likely use molecules with bonds. It might use two separate molecules, one serving as a rapidly utilizable energy currency and another molecule serving as long-term energy storage

The organism would likely use molecules with Covalent bonds.  

Explanation:

A covalent bond is a chemical bond that is prevalent in most matter and facilitates the sharing of electron pairs between atoms. Molecular Bond is another word for a covalent bond.

Molecular bonds are a repository of potential energy. This type of energy is also referred to as Chemical Energy.

Covalent bonds may take the form of single, double, and triple bonds. In order to separate any pair of bonded atoms, energy is required. The more strong a covalent bond is, the higher the amount of energy that is required to break it.

the national environmental policy act (nepa) is a united states environmental law that promotes the enhancement of the environment and established the president's council on environmental quality (ceq). the law was enacted on january 1, 1970. to date, more than 100 nations around the world have enacted national environmental policies modeled after nepa.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
