Many of us have heard of the mythical black hole at the galaxy’s centre. until now, this black hole was something of a story made up by scientists to get attention, ‘the unicorn of the galaxy’ for quite a few people.

But, to burst that bubble, recently NASA’S Event Horizon Telescope (I will come to that soon) has clicked a magnificent photo of that very black hole. This black hole is called Saggitarius-A. This in my opinion is a highly underwhelming name. while it does reflect its position in the sky well, it doesn’t even begin to state the magic of this giant.

Sagittarius-A is a black hole which is about 4.3 million solar masses, which means that the black hole is 4.3 million times larger than our own sun.

Now let’s move on to the event horizon telescope. the event horizon Telescope (EHT) is the telescope used to capture an image of Sagittarius-A. this telescope is unlike any usual telescope. instead of an array of tubes and mirrors, it is a setup of large antennae. These antennae essentially collaborate to capture infrared light. they capture light with wavelengths in micro millimetres, and these are often emitted from black holes. a computer then enhances the image.

The EHT primarily focuses on capturing images of black holes, and hopes to do so better and gain a better understanding of these mysteries.
