The thing is packed with the heft of four million suns. It is in the heart of our galaxy, cloaked behind gas, dust, and stars. It has never been seen before. That is, until today.

As Nadia Drake reports, scientists using a global telescope network have unveiled the first-ever image of a black hole in our galaxy. Named Sagittarius A*, the darkened back hole is surrounded by a glowing silhouette—and it’s striking, not just to astronomers.

”You work on something, but it’s very abstract,” says the University of Amsterdam’s Sera Markoff, “and then suddenly it’s like—there it is. You’re looking at the black hole.”

I wouldn't say "it's never been seen before", but that "we Earthlings have never before seen it". We already have proof that our universe has other life forms elsewhere in it, and not just on our planet.

The image itself doesn't say much.
Meaning and consequences is what makes the difference.

The black hole has been there forever, just because we do not see it means its effects were not the same as before.

What consequences there may be that we just know about now?

Whatever effect it has in the Universe, it had it before and after its discovery.
