By way of a coordinated effort from radio telescopes around the world, scientists have managed to photograph a black hole for the first time ever. The historic achievement was announced by NASA on Wednesday in a statement that included the landmark image and details of how it was captured.
Making this image has required a cooperative effort on the part of international scientific community.(.the Event Horizon Telescope (EHT), is an array of eight radio telescopes located at different sites spread across the planet )
In today's world where we are dealing with wars,extremism, hatred,oppression,isolationism ,and negativity...it's wonderful to see that humanity can set all that aside and work collaborative!y toward one goal.
.It's a pity that politicians don't seem to be able to work together in the same way.

ReplyDeleteFor thousands of years, astronomy was restricted to what we could see with our eyes. But visible light makes up only a tiny fraction of a spectrum emitted by celestial objects. We now know that light is not the universe’s sole means to reveal the mysteries of the heavens. Until recently, we simply lacked the windows through which to view these aspects of our universe. Over the last few decades, astronomers have revolutionized our windows on the universe with telescopes of unprecedented sensitivity to light beyond what our eyes can see.
If we were limited to our unaided senses as our only means of accessing knowledge of the universe we would know very little!
Even with all the instruments we have invented to augment our senses ,95?% of the universe still remains invisible to us
(see, "dark matter")
The part of the universe presently visible to us is like the tip of an iceberg compared with the realities that future technology,instrumentation, and perceptual augmentation aids will reveal!
This image is of the supermassive black hole that lies at the centre of the huge Messier 87 galaxy, in the Virgo galaxy cluster. Located 55 million light-years from Earth, the black hole has been determined to have a mass 6.5 billion times that of the Sun, with an uncertainty of 0.7 billion solar masses.
ReplyDeleteThe Black Hole at the center of the Milky Way galaxy is 4 million times more massive than our sun. It is the size of the orbit of Mercury around the sun.It is 27,000 light years away from earth.
ReplyDeleteThe first image of a Black Hole released by the international consortium behind the Event Horizon Telescope(,a collection of eight synchronized radio telescopes around the wor l d)was in 2019 from a galaxy 53 million light yearss away that is1,500 times bigger than the one in our galaxy.There are lots of less massive and smalller black Holes around, formed during the final collapse and explosion of dying massive stars.Astronomers believe there are about 100 million of these scattered around our galaxy. The nearest one lies just 1600 light years away.
