According to the new map, the core of the Milky Way galaxy, as well as the black hole that resides at its heart, is positioned 25,800 light-years away from Earth. This is closer to the official value of 27,700 light-years adopted by the International Astronomical Union in 1985 than the official value of 27,700 light-years.

Is the Earth near the center of the Milky Way galaxy?
The Earth is located within the Milky Way galaxy, which is the second biggest galaxy in the Local Group. The Milky Way galaxy is a huge spiral galaxy with a spherical shape. Earth sits within one of the spiral arms of the Milky Way galaxy (known as the Orion Arm), which is approximately two-thirds of the way out from the galaxy’s central black hole (named the Galactic Center).
How far away are we from the Milky Way?
Our solar system is roughly two-thirds of the way out from the Galactic Center, toward the edge of the galaxy, according to the International Astronomical Union. In reality, we are 26,000 light years away from the center of the galaxy, or 153,000 trillion miles (246,000 trillion km).
What is the closest black hole to Earth?
If we look at Sagittarius A, the supermassive black hole at the heart of our galaxy, its mass is estimated to be around 4 million times that of the sun. In addition to being one of the tiniest black holes ever discovered, it is also the closest one to us that we are currently aware of, being just 1,500 light years away from us.
Has anyone ever left the Milky Way?
NASA has reported that Voyager 1, which was launched into space on September 5, 1977, has successfully completed its journey out of the Solar System. When Voyager 1 was about to leave the Solar System, it had been traveling through the heliopause, which is an area of space between the heliosphere and interstellar space.
Will humanity ever leave the Milky Way?
The technology necessary to travel across galaxies is well beyond the capability of humanity at this time, and it is solely the topic of conjecture, supposition, and science fiction at this point in history. However, from a theoretical standpoint, there is nothing that indicates that interplanetary travel is inherently impossible.
Have we ever left the Milky Way?
On November 5, 2018, Voyager 2 officially exited the solar system when it passed the heliopause, the barrier that marks the end of the heliosphere and the beginning of interstellar space.
Can a wormhole exist?
In the early days of study on black holes, before they were even given that name, physicists were unsure whether or not these weird things existed in the actual world, and they were right to be skeptical. The concept of a wormhole was first proposed by scientists Albert Einstein and Nathan Rosen in 1915.
Will Sun become a black hole?
No. Stars like the Sun, on the other hand, are just not large enough to collapse into black holes. As a result, the Sun will eventually shed its outer layers, and its core will collapse to create a white dwarf – a dense ball of carbon and oxygen that no longer generates nuclear energy, but which glows because it is extremely hot – many billion years from now.
Is our galaxy in a black hole?
Observational data shows that practically every huge galaxy contains a supermassive black hole at its center, which is consistent with previous findings. The Milky Way galaxy has a supermassive black hole at its Galactic Center, which corresponds to the position of Sagittarius A* in the constellation of Sagittarius.
How many black holes are in the Milky Way?
The majority of star black holes, on the other hand, are extremely difficult to detect. The amount of stars massive enough to form such black holes, on the other hand, leads scientists to believe that there are as many as ten million to a billion such black holes in the Milky Way alone.
Do black holes swallow planets?
Answer: Black Holes devour anything that becomes entangled in their powerful gravitational attraction and becomes stuck within them. A Black Hole is capable of swallowing everything it chooses, including stars, gas, dust, planets, moons, and other celestial objects.
What if there was no life on Earth?
Earth may be comparable to Venus if it didn’t have life on it. There would be no oxygen, but there would be plenty of carbon dioxide, which might result in a runaway greenhouse effect, causing the seas to evaporate. Furthermore, sulphur and nitrogen oxides would most likely be present in the atmosphere, leading to the formation of sulphuric and nitric acid rain.
