One planet loses its atmosphere as two planets collide in outer space

Published

A team of astronomers has identified a planet similar to Earth that may have lost some of its atmosphere two hundred thousand years ago due to a collision.

Only 95 light-years away from Earth, MIT, National University of Ireland Galway, and Cambridge University astronomers discovered evidence of the huge collision in a nearby star system. The HD 172555 star is around 23 million years old, and astronomers believe its dust indicates a recent collision.

Massive impacts, according to a research published in the journal Nature, are responsible for planets like the early Earth reaching their final mass and achieving long-term stable orbital arrangements. 

An important prediction is that debris will be generated by these hits. The researchers discovered a carbon monoxide gas ring co-orbiting with dusty debris around HD172555 between six and nine astronomical units — a zone akin to the outer terrestrial planet area of our Solar System.

Astronomers are attracted by the star HD 172555 due to the odd composition of its dust, which apparently contains a considerable amount of exotic materials in grains much smaller than astronomers would expect. 

Tajana Schneiderman, a doctoral student in the Department of Earth, Atmospheric, and Planetary Sciences at MIT, searched through data from Chile’s Atacama Large Millimeter Array (ALMA) in search of carbon monoxide traces encircling close stars.

The ALMA observatory is a network of 66 radio telescopes whose distance apart may be altered to increase or decrease image resolution.

“When attempting to examine gas in debris discs, carbon monoxide is often the brightest and hence the simplest to locate. Therefore, we reexamined the carbon monoxide data for HD 172555 since it was an intriguing system,” stated Schneiderman. The researchers identified carbon monoxide, which accounted for 20% of the carbon monoxide measured in Venus’ atmosphere, after a thorough analysis of the data.

Surprisingly close to the star, at around 10 astronomical units, or 10 times the distance between Earth and the sun, massive volumes of gas were swirling. The presence of such a vast amount of gas encircling the star necessitated an explanation, and scientists considered several possibilities.

Astronomers investigated theories in which the gas was formed by the debris of a newly born star and by a nearby belt of ice asteroids, but rejected both. The most plausible hypothesis explored by the scientists is that the gas was a byproduct of a major collision.

It is the only scenario that can explain all the characteristics of the data. In systems of this age, we anticipate gigantic repercussions, and we anticipate that these impacts will be relatively common. The timelines, age, and morphological and compositional limitations are all consistent. In this system, the only probable process that may create carbon monoxide is a massive impact, Schneiderman said in a statement.

The team hypothesizes that the gas was discharged by a catastrophic collision at least 200,000 years ago, which is recent enough for the star not to have completely destroyed the gas. According to the amount of gas, the impact was likely massive, involving two protoplanets around the size of Earth.

According to astronomers, the impact was so violent that a piece of one planet’s atmosphere was blown away, resulting in the gas observed today.

Former US Air Force fighter pilot: UFOs use Star Trek-style warp drive

Published

A former US Air Force fighter pilot asserts that he has deciphered
the method behind the extraordinary maneuvers of UFOs, reports dailystar.co.uk.

Over
the past two decades, numerous military encounters with these enigmatic
crafts have been reported, prompting a significant investigation by the
Pentagon.

One of the most renowned sightings occurred during the
USS Nimitz encounter, where fighter pilots witnessed a UFO descending
from 28,000 feet to just above sea level in less than a second.

This
astonishing movement would imply that the craft reached a staggering
speed of 19,000 miles per hour, a velocity that would be fatal to any
human pilot.

According
to Chris Lehto, a former USAF pilot, the craft exhibits two key
characteristics: it moves without inertia, essentially lacking weight,
and it accelerates at an incredibly rapid pace without affecting its
surroundings.

Chris
believes that the explanation lies within a technology that seems
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.

The
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.

While
the Alcubierre Drive remains a hypothetical concept with challenges to
overcome, Chris notes that the required energy is no longer believed to
be unattainably large.

Patents
filed with the US patent office outline the potential workings of the
drive, as well as another groundbreaking technology theorized by
American aerospace engineer Salvatore Pais.

Pais suggests that
high-powered rotating magnets could theoretically eliminate an object’s
inertia, and he has filed a patent for a starship based on this
principle.

However, Chris maintains skepticism regarding Pais’
theory. He explains that while Pais’s patent applications for the US
Navy attracted attention for their potential energy-related
applications, doubts have been raised about their feasibility. There is
speculation that they may be scams, pseudoscience, or disinformation
intended to mislead adversaries of the United States.

Alternatively,
rival theories propose that the “Tic Tac” UFO is a classified Pentagon
project testing similar advanced technologies discussed by Chris.

A Mysterious Earth-Like Planet Has Just Appeared in Our Solar System, Scientists Say

Published

Scientists say they have found evidence of a new Earth-like
planet that has suddenly appeared in our Solar System and is orbiting
the Sun.

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
System.

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
Kuiper Belt.

“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
noted.
