Sagittarius A*
Astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy.
The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes.
For Scale
The object is a staggering 4 million times the mass of our Sun. And the ring is roughly the size of Mercury's orbit around our star. That's about 60 million km across.
Fortunately, this monster is a long, long way away, some 26,000 light-years in the distance.

Will the Earth die today?
CERN's Large Hadron Collider fires up for third time to unlock more secrets of the universe.
And people all over the world are panicking that they will create a black hole that'll suck the earn in.
But no worries my people, here's why it won't be the end of us all. See when the LHC was first built, it was explained that microscopic black holes could be created. This generated panic in the non-scientific communities that the black holes would swallow the earth. But, while black holes will be created, they are so small that they evaporate nearly immediately and pose no risk to the earth. Because these black holes are fed any mass to increase their size and power. And yet every time the LHC gets turned back on, people bring it up again, and cause havok.

Also the reason any black hole actually generated would evaporate immediately is because they'd have no mass to back themselves up. At most they'd weigh something like a few hydrogen atoms. The resulting black hole would dissipate into Hawking radiation almost instantaneously.
To give an idea how much of a non issue it would be: If you took the moon and compressed it down until it became a black hole, absolutely nothing would happen to us. We'd lose the lunar cycle and animals that relied on moonlight would be f*cked up, but the black hole moon would behave just the same as it always does. It'd revolve around the earth at the same speed. The tides would stay the same. We wouldn't get sucked up into it. The event horizon (the actually dangerous part) would be about the size of a medium sized grain of sand. And that's a black hole with the mass of the moon!
The LHC isn't gonna do anything to us.

This picture I absolute love!
The first simulated image of a black hole calculated with an IBM 7040 computer ysing 1960 punch cards, that's about 32,000 bytes and then hand plotted by french astrophysicist Jean Pierre Luminet in 1978
It's a fact that there are some truly genius people out there in the world despite the 99% of us stupid ones.

On October 9, astronomers discovered an extremely intense and persistent pulse of high-energy radiation that sent shockwaves to Earth.
A surge of X-rays and gamma rays swept through the solar system triggering detectors on NASA's Fermi Gamma-ray Space Telescope, Neil Gehrels Swift Observatory, and Wind spacecraft, among others.
The burst was detected by Orbiting High-energy Monitor Alert Network (OHMAN).
The burst was detected for nearly 10 hours and astronomers believe that the explosion was closer to us.
Scientists have named it GRB 221009A It originated from the direction of the constellation Sagitta
This phenomenal has ionized parts of the Earth's atmosphere and even managed to break some satellites.

This is one of the most impressive visualization I've ever seen

He shows the relative scale of planets, our solar system, stars, galaxies and most of all a black hole. It is sooo well done! 👏
The moment he visualized a 4.3 million solar mass blackhole is 🤯

I already am kinda scared of black holes, I didn't need to know all of these information about them.
