The closest black holes to Earth are discovered | Digital Trends Spanish

Thanks to the telescope Very Large Telescope (VLT), astronomers discovered the closest black holes to Earth known so far.

Both are supermassive and are found in the galaxy NGC 7727, in the constellation Aquarius. And although they are the closest to our planet, they are still very far away, 89 million light years away.

To put that number in context, the closest black holes prior to this discovery were 470 million light-years away. On the other hand, both are at a distance of 1,600 light years from each other.

The size of one of these holes is 154 million times the mass of the Sun, while the other is smaller and only has a mass of 6.3 million that of the Sun.

It is very possible that in the future these black holes will find themselves in a great space collision. According to science, they are always in the center of galaxies; So that these two newly discovered are so close to each other means that there was a merger of galaxies and that they will inevitably have the same fate in 250 million years.

The appearance of these supermassive black holes in remote places in space suggests that there are many more in the universe. Astronomers believe that the figure could be 30 percent higher than previously believed and that, with all certainty, they will continue to appear as space is explored thanks to instruments such as the VLT telescope located in the middle of the Atacama desert.
