Astronomers have found the closest pair of supermassive black holes ever seen on Earth.

He said the two objects — which are just 1,600 light-years apart — also have a much smaller separation than any other previously observed pair of supermassive black holes and will eventually merge into a single massive black hole.

What is NGC 7727 galaxy and how far is it?

NGC 7727 is a spiral galaxy in Aquarius that is approximately 89 million light-years away from Earth.

It was first discovered by William Herschel in 1785.

Several star streams and plumes are associated in the galaxy, which astronomers believe may be the result of a merger with another spiral galaxy about a billion years ago.

At its center is a supermassive black hole whose mass is about 154 million times that of our Sun.

It has been paired with a separate black hole, just 1,600 light-years away, which astronomers say is 6.3 million solar masses.

The large black hole at the center of the galaxy NGC 7727 in the constellation Aquarius was found to be about 154 million times the mass of our Sun, while its companion is 6.3 million solar masses.

Experts were able to determine these masses by observing how the gravitational pull of black holes affects the motion of the stars around them.

According to the researchers, this is the first time the mass for a pair of supermassive black holes has been calculated in this way.

This achievement was made possible thanks to the system’s proximity to Earth and detailed observations obtained using the VLT at the Paranal Observatory in Chile and additional data from the Hubble Space Telescope.

Astronomers suspected that the galaxy hosted two black holes, but they had not been able to confirm their presence until now.

That’s because we don’t see large amounts of high-energy radiation from their immediate surroundings, which would otherwise give them away.

Lead researcher Karina Vogel from the University of Strasbourg said: “Our discovery implies that there may be many more of these remnants of galactic mergers, and they may contain many hidden massive black holes that are yet to be discovered.” are waiting for.”

‘This could increase the total number of known supermassive black holes in the local universe by up to 30 percent.’

The discovery of similarly elusive supermassive black hole pairs is expected to make a huge leap forward with new The Extremely Large Telescope (ELT), which is set to begin operating in Chile’s Atacama Desert later this decade.

“The detection of a supermassive black hole pair is just the beginning,” said co-author Stephan Miske, an astronomer at the European Southern Observatory in Chile.

‘With the HARMONI instrument on the ELT we will be able to detect this much more than is currently possible.

‘ESO’s ELT will be an integral part of understanding these items.’

The European Southern Observatory was established in 1962 as an intergovernmental organization.

Today it is supported by 16 member states, including France, Germany, Spain and the United Kingdom, along with the host state Chile.

The discovery of black holes is published in the journal astronomy and astrophysics,

The Very Large Telescope is a powerful ground-based instrument in Chile

The European Southern Observatory (ESO) has built the most powerful telescope ever built in the Atacama Desert of northern Chile.

It’s called the Very Large Telescope (VLT) and it’s Widely regarded as one of the most advanced optical instruments ever made.

It consists of four telescopes, whose The diameter of the main mirror is 27 feet (8.2 m).

There are also four movable six feet (1.8 m) diameter auxiliary telescopes.

The larger telescopes are called Antu, Kuyen, Melipal and Yepun.

The first of the Unit Telescope, ‘Antu’, went into regular scientific operation on April 1, 1999.

Together, telescopes can form a giant ‘interferometer’.

This allows the interferometer images to be filtered for any unnecessary obscuring objects and, as a result, astronomers can see details up to 25 times finer than with individual telescopes.

It has been involved in finding the first image of an extrasolar planet, as well as tracking individual stars revolving around the supermassive black hole at the center of the galaxy.

It also observed the brightness after the most distant known gamma ray burst.
