Into The Depth Of Space

Dear Pluto

The assumption was widely accepted before 2006 that Pluto was the 9th planet of Solar System. However it has been decided since then that now Pluto is a "Dwarf Planet". If so, what are the conditions of being a planet?
According to definition made by International Astronomical Union in 2006, there are three main criteria celestial bodies must meet.

-It must be an object which independently orbits the Sun.

-It must have spheroidal shape.

-Finally, must be large enough to "Dominate" its orbit, it is not a planet.

The last criteria Pluto cannot actualize caused it to fail to be regarded as a planet. The reason behind is that Pluto isn't the one which is massive enough in its orbit and it shares its orbital neighborhood with Kuiper Belt Objects.
Thereby any large body that does not meet this third condition classed as a "Dwarf Planet".

The Latest

On July 14, 2015, NASA’s New Horizons spacecraft made its historic flight through the Pluto system, providing the first close-up images of Pluto and its moons and collecting other data that has transformed our understanding of these mysterious worlds on the solar system’s outer frontier.

Scientists are still analyzing and uncovering data that New Horizons recorded and sent home after the encounter.
Pluto which is smaller than Earth’s Moon has a heart-shaped glacier that’s the size of Texas and Oklahoma. This fascinating world has blue skies, spinning moons, mountains as high as the Rockies, and it snows, which is red. 
We still must effort further to discover the mysterious nature of amazing Pluto.



Inside Of Black Holes

Although many people around the world assume that black holes are such a mass and unreliable phenomenon, it is so much worth to talk about since it is more than a science fiction and a complication. Many scientists believe, black holes can reveal some realities we need to know about universe and spacetime.
To make  creepy definition, a black hole is such a depthless pit even light cannot get out.
According to Professor Hawking (RIP) from Cambrige University, A black hole has a boundary, called the event horizon. It is where gravity is just strong enough to drag light back, and prevent it escaping. Because nothing can travel faster than light, everything else will get dragged back.
And he continues in his article, If you fall towards a black hole feet first, gravity will pull harder on your feet than your head, because they are nearer the black hole. The result is, you will be stretched out longwise, and squashed in sideways.. If the black hole has a mass of a few times our sun, you would be torn apart, and made into spaghetti, before you reached the horizon.
Since non of us want to become a spaghetti, we won't attempt to dive in a black hole.

From outside, it is not likely to say what's in black hole. All we know about this mysterious fact is that as light cannot escape once past the black holes' event horizon they can't actually be 'seen' in a traditional sense. Yet we can infer their existence from their impacts on other bodies in space such as suns, stars and gas clouds. 
It might soon be possible to detect the boundary of the event horizon around the black hole as the observations and research keep going to be made.
