Scientists from the University of Sheffield have identified a new planet with rings in the solar system. The results of the work are described in the journal Nature, reports cnn.com.
We are talking about the dwarf planet Quaoar, located at the very edge of the solar system. The object was first discovered back in 2002, it is half the size of Pluto and orbits the Sun behind Neptune.
Now, with the help of modern HiPERCAM equipment, installed on the world’s largest optical telescope Gran Telescopio Canarias (GTC), the rings have been discovered around the planet.
At the same time, Quaoar rings are too small and weak to be seen in the picture. The discovery was made thanks to the observation against the background of the shadow from the star, which arose when Quaoar obscured the luminary during its rotation cycle.
The event lasted less than a minute, but during that time the rings created static in the light that indicated their presence.
Ring systems are not very common in the solar system. The most famous are the rings of Saturn and Jupiter. The uniqueness of Quaoar lies in the fact that it is located at a distance of more than seven planetary radii.
This is more than twice what was previously considered the maximum distance according to the “Roche limit” – the boundary within which ring systems can exist. For example, the rings of Saturn are located within three planetary radii.
Professor Vik Dhillon, of the University of Sheffield’s physics and astronomy department, said: “It was unexpected to discover this new ring system in our solar system.
“And it was doubly unexpected to find the rings so far out from Quaoar, challenging our previous notions of how such rings form.”
A new study is forcing scientists to rethink ring formation theories.
Former US Air Force fighter pilot: UFOs use Star Trek-style warp drive

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.

be unattainably large.

intended to mislead adversaries of the United States.

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
