Aliens explored: This book by EX-NASA Scientist Lisa Kaltenegger will answer all your questions on extraterrestrial life

Former NASA astronomer Lisa Kaltenegger has been researching space for her new book, Alien Earths. In the book, she raises the possibility that extraterrestrial life exists on a world primarily submerged in water, home to sea creatures like octopuses. She also describes two additional planets: one that has molten rock raining from it and one that never faces the sun, so one side is always dark. Lava makes up the surface, after all.

Is there a possibility?

The researcher investigated a large number of exoplanets, or planets orbiting stars outside of our solar system. Some of these planets resemble Earth in certain ways, or they might be suitable habitats for life. Former NASA astronomer Lisa Kaltenegger has been researching space for her new book, Alien Earths.

The book unveils facts!

The researcher investigated a large number of exoplanets, or planets orbiting stars outside of our solar system. Some of these planets resemble Earth in certain ways, or they might be suitable habitats for life. Former NASA scientist Dr. Lisa Kaltenegger offered insights from her book, The World that Shook Science, in a Daily Mail article. She mentioned that in 1992, we found the first exoplanet. We have discovered more than 5000 exoplanets since then. Of them, about seventy may have circumstances that are fit for life. Some of these worlds, though, are up to 17,000 light years away from us. For comparison, it would take 6.9 million years for the fastest rocket ever created by humans to reach them. Even with these findings, it is still extremely difficult, if not impossible, to find extraterrestrial life on such far-off planets.

Moreover on the alien at stake

Dr. Lisa said it is difficult to find aliens. We might not even be aware that they are in front of us. Nonetheless, according to the University of Puerto Rico's Planetary Habitability Laboratory, there are 29 exoplanets that resemble Earth and potentially support life. However, Proxima Centauri, a unique location 4.25 light years away, may be a hangout for extraterrestrials. Since the sun never sets or rises here, it could be a really great location to live. CoRoT-7 b is a potential exoplanet located in a different region of the galaxy. It is 489 light-years from Earth and is continuously erupting in flaming lava. It sounds like a fairly bad place to be, with very little prospect of survival, from the standpoint of a human. Hey, aliens might still live there. Additionally, there may be life nearby Kepler-62, an orange dwarf star. Our solar system is located roughly 980 light-years away from this exoplanet.
