The speed of light is the Universal speed limit – nothing can travel faster than light. In the vacuum (commonly denoted c), its exact value is 299,792,458 meters per second (around 186,000 miles per second). In other words, if you could travel at the speed of light, you could go around the Earth 7.5 times in one second.Continue reading Speed of Light – See how torturously slow it is
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
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
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
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”.Continue reading Planet Nine – Where is it?
