Scientists observe strange lights in the heart of the Milky Way

Astronomers spot periodic lights coming from near the black hole at the center of our galaxy.

The supermassive structure dates to about 400 million years after the Big Bang, and it’s particularly large for its age.

Cosmologists believe that multiple universes really exist; they call the whole vast collection, which might even be infinite in number, the ‘multiverse’. But how are all these universes generated? There are several ways, each radically different from the others, each incredibly fascinating, each capable of generating infinite universes.

A group of over 400 scientists have spent the last decade studying supernovae with unprecedented results about the expansion of space and the role of dark energy.
The discovery of a second ultra-large structure in the remote universe has further challenged some of the basic assumptions about cosmology.
The Big Ring in the Sky is 9.2 billion light-years from Earth. It has a diameter of about 1.3 billion light-years, and a circumference of about 4 billion light-years. If we could step outside and see it directly, the diameter of the Big Ring would need about 15 full moons to cover it.
It is the second ultra-large structure discovered by University of Central Lancashire (UCLan) Ph.D. student Alexia Lopez who, two years ago, also discovered the Giant Arc in the Sky. Remarkably, the Big Ring and the Giant Arc, which is 3.3 billion light-years across, are in the same cosmological neighborhood—they are seen at the same distance, at the same cosmic time, and are only 12 degrees apart in the sky.

Researchers have identified the oldest black hole ever observed, dating from the beginning of the universe, and determined that it is ‘eating’ its host galaxy to death. The study, published in the journal Nature, used the James Webb Space Telescope (JWST) to locate the black hole, which formed 400 million years after the Big Bang, more than 13 billion years ago.

Researchers using the James Webb Space Telescope have uncovered the oldest black hole ever detected—and declared a new era in astronomy.
It was found at the center of GN-z11, a galaxy first discovered in 2017, about 13.4 billion light-years away from our Milky Way galaxy—but about 100 times smaller. That means it exists just 400 million years after the Big Bang, which is thought to have created the universe. However, the black hole looks to be about a billion years old, suggesting problems with theories about how quickly black holes form.
The discovery, announced in a paper published today in the journal Nature, is the result of the sensitivity of JWST, which can see deep into the infrared, detecting old light that has been traveling across deep since the dawn of time.
