Proxima Centauri b May Have Oceans

Proxima Centauri b, the Earth-like planet orbiting the red dwarf Proxima Centauri may have oceans, scientists say. The planet was discovered in August 2016 and caused excitement because it’s in the habitable zone of its star, and it’s rocky. And it’s in the Alpha Centauri, the closest star system to us!

Researches of France’s National Center for Scientific Research (CNRS) have calculated the size and surface properties of the planet and concluded it may be an “ocean planet” similar to Earth. There are possibilities, though, it may have continents and oceans like Earth, or its entire surface may be covered by a massive ocean.

Planet with Three Suns

On March 17, 1941, John W. Campbell, editor of Astounding Science Fiction, asked Isaac Asimov that: “What, if people see the stars once in a thousand of years?” Campbell has had read Ralph Waldo Emerson’s 1836 essay “Nature” and Emerson was saying in the first chapter that “If the stars should appear one night in a thousand years, how would men believe and adore, and preserve for many generations the remembrance of the city of God!”

Campbell wanted Asimov to read that quote, and asked him the question above, “What if people see the stars once in a thousand of years?” Asimov said, “I don’t know…” Campbell said: “I think men would go mad.” And he added: “Now, go and write a story about that.”

Planet Nine – Where is it?

In January 2015, Caltech (California Institute of Technology) astronomers Konstantin Batygin and Michael E. Brown published an article titled Evidence For A Distant Giant Planet In The Solar System and announced calculation-based evidence of a massive ninth planet. Despite they have had started their research to demonstrate that there’s no ninth planet, they reached the exact opposite result: there must be a ninth planet beyond Pluto, and it’s probably 10 times the mass of Earth (for comparison, Neptune has 17 times as much mass compared to the Earth).

In an effort to state Planet Nine’s exact location, a team of French scientists used the data from the Cassini–Huygens (an unmanned spacecraft orbiting Saturn, launched on October 15, 1997). They couldn’t able to find the exact location of the giant planet, but they narrowed down the “possible areas”.
