NASA marks #BlackholeFriday


California: The National Aeronautics and Space Administration (NASA) also joined ‘Black Friday’ celebrations with many parts of the world by talking about ‘Basics of Black Hole’. While for the rest of the world, Black Friday usually depicts the beginning of the countdown for Christmas holiday season, NASA marked the ‘Black Hole Friday’ by giving an insight on the mysterious formations in the universe that have continued to baffle the researchers with new discoveries to this date.

The United States’ space agency posted stunning images on Twitter and shared some details about the ever-intriguing world of space. NASA defines a black hole – for the uninitiated – as “a great amount of matter packed into a very small area – think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape.”

In its tweet, marking the equivalent of Black Friday, the space agency wrote: “You’ve heard of the big #BlackFriday sales, but we’re taking today to celebrate a doorbuster of cosmic proportion: #BlackHoleFriday. (sic)”

And then it introduced the curious minds to ‘blazars’ – “supermassive black holes feeding off material, which can create two powerful jets of high-speed particles.”

Black holes don’t emit light- this is known. But what then gives them away? “Swirling gas, energetic jets, and even ripples in space-time give them away,” tweets NASA.
