Are We Alone?

Every year, scientists add new fascinating species into the encyclopedia of life. As a Harry Potter's fan, one little creature discovered this year, Gryffinfor's Hat amazed me! All this new discoveries are made on the surface of our planet Earth, and despite the huge number of discoveries every year, we are far from finding everything. Now, imagine if we find another planet with different environment where life develops separately from Earth. This could change radically our taxonomy. In this article "Looking for life in all the right places" chosen from NASA, we can see that space exploration has an important place in our society. NASA created an exoplanet program to find signs of life in other planet. A technique used by NASA in order to find essential atoms for life such as oxygen, carbone and hydrogen is spectroscopy. They analyze the color and the wavelength emitted by the planet to determine the presence of specific atoms. However, we don't really know how is life on other planet. We expect something similar to us, but maybe life on other planet is based on different combinations of molecules than on Earth, and we could never discover this mystery!


First of all, thumbs up for the catchy title that raises an interesting question while staying a little vague in order to force the reader to want to know more. Also, although the post starts with in some way a kind of personal tone, it switches quickly to a professional tone. This is very good because it catches the reader's attention fast at the very beginning. Also, the summary is very well formulated and it grasps the essential of the article you are presenting, which makes it very pertinent for someone looking to get information on this topic. Maybe one thing that could have been developed more is the connection of this subject to biology with the atom spectroscopy and how it is being used in this situation.
Moreover, here is a link to another source of information about the exploration of other kinds of life. This might be interesting due to the brief summary it gives on space missions, telescopes and spectrgraphs and what role it plays in exploration for life on other planets.
