The biggest galaxy ever seen, known as Alcyoneus, has been discovered, according to a recent study that was published in the journal Astronomy & Astrophysics.
Alcyoneus is an elliptical galaxy that is 160 times bigger than our Milky Way galaxy and is located around 3 billion light-years from Earth. It has a diameter of 16.3 million light-years.
Alcyoneus is a radio galaxy, which means that its supermassive black hole consumes matter and produces two plasma jets that travel at almost the speed of light. After traveling millions of light-years, these jets cooled down and fanned out, generating radio waves that made the galaxy visible to scientists.
While plasma-filled radio lobes are common in galaxies, the magnitude of Alcyoneus’ lobes is unique, making it difficult to understand how it expanded to such extent. When going through data seeking for big, diffuse radio lobes, the researchers analyzed data gathered by the Low-Frequency Array (LOFAR), a network of radio telescopes across Europe. They stumbled onto Alcyoneus by accident.
One theory being considered by experts looking at the probable origins of Alcyoneus’ enormous size is that its surroundings may be less dense than normal, enabling its jets to extend to previously unheard-of sizes. Another theory is that Alcyoneus is located within the cosmic web’s filament, a structure made of gas and dark matter that connects galaxies.
The explanation for why Alcyoneus has grown to such a vast extent, according to the researchers, will provide light on how other galaxies develop. They point out that the biggest giant radio galaxies will probably have them if host galaxy traits are crucial for giant radio galaxy development. The biggest radio galaxies are anticipated to be located in certain large-scale settings that are particularly favorable for gigantic radio galaxy development.
Alcyoneus, despite its enormous size, has a center supermassive black hole that is 100 times less massive than the biggest known black hole and a total mass that is around half that of the Milky Way.

straight out of science fiction. He proposes that the answer to the UFO
enigma lies in the Alcubierre Drive, a theoretical interstellar engine
conceptualized by Mexican physicist Miguel Alcubierre in 1994.
Alcubierre Drive employs a form of “space warp” technology, reminiscent
of what has been depicted in episodes of Star Trek. By bending space, a
craft inside a “warp bubble” could potentially travel at or even
surpass the speed of light without violating the known laws of physics.

A Mysterious Earth-Like Planet Has Just Appeared in Our Solar System, Scientists Say
Scientists say they have found evidence of a new Earth-like
planet that has suddenly appeared in our Solar System and is orbiting
Physicists, including those from the National Astronomical Observatory
of Japan, said the planet is likely to be the mysterious ‘Planet Nine’
that was hypothesised to exist in the far outer edges of the Solar
Several studies in the past have suggested there is likely an
undiscovered planet beyond the Kuiper Belt – a stellar disk of materials
such as asteroids, space rocks, comets around the Sun in the outer
Solar System past the orbit of Neptune.
Independent.co.uk reports: In the new research, published recently in The Astronomical Journal, scientists
found that some of the objects in the Kuiper Belt behave in a way
indicative of the presence of a small planet among them.
One such object, they said, is about 500 astronomical units (AU) from
the Sun, where 1 AU is the distance between the Sun and the Earth.
In comparison Neptune is at a distance of 30 AUs from the Sun.
Some of these were also found to have “odd” orbits suggesting they
are being pull by the gravity of a cosmic entity larger than those that
typically influence such objects.
Computer simulations run by the scientists indicate that the most
likely explanation for the observations was another hidden planet in the
“We predict the existence of an Earth-like planet,” researchers wrote in the study.
“It is plausible that a primordial planetary body could survive in
the distant Kuiper Belt as a Kuiper Belt planet (KBP), as many such
bodies existed in the early solar system,” they added.
If such a planet exists, researchers say it would have a mass about
1.5 to 3 times that of Earth with an inclination of about 30 degrees.
They say the theorised planet’s orbit would likely place it between 250 and 500 AU from the Sun.
Researchers say the discovery of such a planet close to the Kuiper
Belt can unravel new constraints on planet formation and evolution.
“In conclusion, the results of the KBP scenario support the existence
of a yet-undiscovered planet in the far outer solar system,” scientists
