Sagittarius A* – The Milky Way’s Black Hole

Sagittarius A* is a supermassive black hole at the Milky Way’s heart. Known as Sagittarius A too, it has been a focus of scientists for a long time. Its discovery has fascinated many.

This black hole has a mass like 4.154 million Suns. It affects how stars and other objects move near it. It’s about 26,000 light-years from Earth, and it’s very important for our galaxy’s shape and actions.

Sagittarius A* is interesting because it gives off weak radiation. It’s different from other black holes in this way. We see it best in infrared and radio light. This helps us learn more about it.


The discovery of Sagittarius A* was a big step forward. It was thanks to the Event Horizon Telescope (EHT) project. In 2022, EHT showed us the first image of Sagittarius A*. Seeing its silhouette was a huge moment. It proved there’s a black hole in our galaxy’s center.

Sagittarius A* is an amazing part of the universe. It shows us the beauty and mystery of space. Researching it helps us understand black holes, galaxies, and the forces of the universe.

The Naming of Sagittarius A*

The Milky Way’s center hosts a big black hole, called Sagittarius A*. This black hole is key in astronomy and gets a lot of attention. Ever stopped to think about why it’s called Sagittarius A*? Let’s explore how this name came to be and what it means.

In 1954, experts noticed a strong radio signal coming from the galaxy’s center. They named it Sagittarius A. John D. Kraus, Hsien-Ching Ko, and Sean Matt did this discovery. It showed to be the strongest radio source in Sagittarius. In 1982, Robert L. Brown added a star to the name, calling it Sagittarius A* (Sgr A*) to show how special it was.1

Sagittarius A* is very important in exploring our Milky Way’s secrets. Its location at the center of our galaxy is critical for astronomy. It’s the focus of a lot of scientific study and space exploration.2

Sagittarius A* Image and Characteristics

In 2022, the Event Horizon Telescope gathered the first image of Sagittarius A*. It shows a dark part in the center, with a bright ring around it. Sagittarius A* is in the heart of our Milky Way galaxy. It’s about 26,673 ± 42 light years from Earth.

Sagittarius A* is a Super-Massive Black Hole with a mass equal to 4.154 million Suns. Its size is 51.8 million kilometers across. This makes it very interesting to scientists and astronomers.

Bolometric luminosity is important because it shows how much light and heat something gives off. Sagittarius A* gives off 100 times more light than the Sun. It shines in many light forms, like infrared, X-rays, and gamma-rays. Even though it looks still, it’s surrounded by moving gas, showing it’s very active in emitting light.

The Event Horizon Telescope found a ring around Sagittarius A* that’s 51.8 ± 2.3 microarcseconds wide. The dark center of the black hole, called its shadow, is 48.7 microarcseconds wide. These sizes tell us a lot about the black hole’s shape and size.

Sagittarius A* is wider than 51.8 million kilometers and it’s really hot, at about 10 billion Kelvin. These numbers show how extreme this black hole really is.

More than 300 researchers from 80 places worked together to take Sagittarius A*’s picture. They used a lot of data, about 4,000 terabytes, to do it. It was quite a team effort.

Learning more about Sagittarius A* helps us understand supermassive black holes better. This knowledge is key in unlocking the secrets of the universe.

Event Horizon Telescope and Sagittarius A*

The Event Horizon Telescope (EHT) is many radio telescopes working as one. It changed how we see black holes. It took amazing pictures of Sagittarius A*, the massive black hole at our galaxy’s center.

This telescope network acts like a single giant telescope. It combines the power of eight observatories worldwide. This lets us see space’s wonders in more detail than ever before.

The EHT looked at Sagittarius A* in a new way. It taught us more about black holes and the force of gravity. These findings improve our grasp on how space works.

Looking at the EHT’s data, scientists figured out a lot about Sagittarius A*. They learned about its size, the mass, and the gas swirling around it. This helps us study black holes better.

The EHT actually took a picture of Sagittarius A*. It was a huge moment in space science. This image showed the world something amazing in our own galaxy. It proved how important the EHT’s work is.

The EHT is opening new doors in space science with its work. It helps us explore black holes and the universe. This is a big step in learning about space’s biggest secrets.
