NASA celebrates #BlackHoleFriday by releasing breathtaking images

After series of mesmerising pictures, US Space Agency NASA has again tweeted some breathtaking taking pictures of Black Hole on the occasion of Black Friday. While people were celebrating the special occasion by buying new products, NASA tried to celebrate the day in a different style by telling people about Black Holes and releasing some astonishing pics.

Some might not know what exactly Black Hole is? Black Holes are formed after death of a gigantic star, at this stage everything starts to collapse inside the star and tonnes of mass gets concentrated in a very small area leading to very high gravitational pull such that not even light can escape its gravity. Thus, as the name suggests Black Holes aren’t empty like a hole instead they are the most concentrated objects in the universe.

Since, all the light passing near the Black Holes gets trapped we are unable to see it by naked eyes and it can only be seen through special telescopes. Black Holes are important as without them our galaxies would not exist and it plays a very crucial role in formation of galaxies. This year NASA tweeted five breathtaking images which is a delight to watch especially for stargazers as they wait for the American Space Agency to release these kinds of images.

    They are black holes because they appear to be black. However they aren’t really as black as one might think them to be in fact they might be really very bright because they allowed x rays to escape but in any case can eat up massive stars. Is it the latter radiate the x rays and due to large distance from the centre of the black hole some x rays escaped. It is significant conclusion because till now it was believed no one can return from a black hole to tell a tale of what was inside maybe a probe can send images after all ?

      Black hole cannot emit any light, including x rays. The x rays we observe from here are from the accretion disc that possibly comes from the material falling into the black hole (but before it actually falls). The material could be a star too. That material is heated to extreme temperatures as it experiences extreme compression and friction from rapid motions around the black hole.

      The probe, once it enters the even horizon, the point of no return, cannot send any images back, assuming it even survives.
