  • Earth-Sized Exoplanet Proxima B Could Have Oceans Of Water

It is being speculated that the earth-sized exoplanet Proxima B could actually harbor life due to the presence of an ocean of water on it.

Proxima B is a world unto itself. It is the “in” thing in the news nowadays. More data concerning it has been unearthed from scanning the night sky. Recent evidence points in the direction of this earth-sized exoplanet harboring life.

Yet the question remains that is it actually capable of supporting life? If so, can humans go and live on its surface? The possibilities are many but the issue has not been resolved uptil now.

The complete epithet of Proxima B is “Proxima Centauri b”. It is 1.3 times as large as our planet earth and it lies 4.25 light years away from our third rock from the sun.

This planet received extra attention when it was found that it could support life due to the presence of a lot of water on its surface. In fact, oceans of liquid water exist on this planet. It is the presence of water that just might make it possible to sustain life on this planet.

The discovery of water on Mars was also a big deal back in the days when the discovery came to light. There has been speculation that Proxima B may be a home to certain primitive life forms, according to Bustle via ScienceAlert.

Whether or not thiae planet is habitable remains a moot point. Just being able to support life doesn’t make a planet one which humans can inhabit. Such automatic correlation does not exist in real life.

The late astrophysicist Carl Sagan wrote regarding the presence of many planets out there that might not only support life but be capable of being a home away from home for human beings.

Life as we recognize it is a biochemical phenomenon. Thus these alternative life forms that may exist on planets like Proxima B are most probably molecular in nature.

It is the resemblance of the conditions of Proxima B and the earth that have the scientists and laypersons enthused. Yet the ground reality is that this “colonization talk” is too simplistic at this stage in our evolution as a species.

Proxima B is most likely more like Neptune and so it may prove to be a difficult place to colonize in the end. Furthermore, the temperature of this planet remains a mystery. Until that crucial factor is known, nothing can be done on a practical level.
