Are UFO revelations true? Buzz Aldrin clears lie detector test on UFO sighting

Astronauts Buzz Aldrin, Al Worden, Edgar Mitchell and Gordon Cooper have one thing in common, they are among the ardent defenders of UFO theory and claimed to have seen or chased many during their space travels. Now, all the four have cleared a lie-detector test, which reiterates their claim.

The lie detector test was carried out using the latest technology and experts said they were “completely convinced” with the results that they are telling the world truth about signs of alien life.

Buzz Aldrin, now 88, was the second human alogn with Neil Armstrong to set foot on the moon in their historic Apoll 11 mission in 1969. He claimed later that he saw a UFO. “There was something out there that was close enough to be observed, sort of L-shaped,” he said repeatedly.

The Institute of BioAcoustic Biology in Albany, Ohio, which has conducted the test, preferred to keep its technology top secret though. They have claimed that they used complex computer analyses of the astronauts’ voice patterns and more reliable than current lie detector tests.

Edgar Mitchell, another who took the test was the sixth astronaut to walk on the moon, who had earlier claimed that “aliens have contacted humans several times”.

Al Worden, 86, who had piloted the Apollo 15 mission revealed similar views to Good Morning Britain viewers with his claims earlier to have seen extra-terrestrials. In addition, the voice recordings of Edgar Mitchell and Gordon Cooper, both now dead, were also analysed by the Ohio-based institute.

Mitchell was part of the Apollo 14 mission and Cooper was also a space pilot who claimed to have chased UFOs during his flights.

Aldrin has been in the news recently for advocating an affordable plan to get humans to Mars.

Since Earth does a lap of the Sun once every 365.256 days and Mars too does a lap of the Sun once every 686.93 Earth days, he said we can overlay these two orbits with a third orbit, that of a spacecraft, which takes 2 and 1/7th years to complete. This spacecraft can meet up with the two planets, he said.

Instead of using fuel to change direction, the spacecraft could use gravitational slingshot manoeuvres to reduce the cost of each trip, he explained.

Stephen Hawking Dead, Last Advice to Humanity to Escape Earth Remains

Famous physicist and cosmologist Stephen Hawking, who was confined to a wheel-chair since late 1970s, died on Wednesday, March 14, when the world was celebrating the ‘Pi in the sky’ and the birth anniversary of Albert Einstein.

His last prediction was that aliens would invade the earth and it is better for the humanity to escape and colonize either Mars or the Moon before it’s too late.

Born on 8th January 1942 in Oxford to elite parents who attended the University of Oxford, Hawking moved with his family to several places and studied at different schools before a long stint at St Albans School, where he met his mathematics guru Dikran Tahta and ventured into applied physics and even built a computer from clock parts during the late 1950s.

His entry at the Oxford was pre-destined but he was disappointed with his guide Dennis William Sciama, a cosmologist, as he wished to be a student of astronomer Fred Hoyle. His lifetime shock came in 1962 when he was first diagnosed with motor neurone disease, that had gradually confined him on a wheelchair rest of his life.

But on his research front, he remained on top and involved himself in debates covering the origin of the universe, the Big Bang theory or the Black Hole concept. In 1966, he obtained his PhD in theoretical physics with specialisation in general relativity and cosmology but his later findings have set the world change its perception of the universe and the world above us in the sky.

Japan scientist finds 1 out of 15 exoplanets habitable

Japanese astronomer team led by Teruyuki Hirano of Tokyo Institute of Technology has validated 15 exoplanets orbiting red dwarf systems and found one of them highly akin to Earth and habitable. It could be of particular interest as researchers describe it as a ‘super-Earth’, which could harbour liquid water, and potential alien life.

One of them, K2-155 located around 200 light years away from Earth, has three transiting super-Earths, which are slightly bigger than ours and interestingly the outermost planet, K2-155d, with a radius 1.6 times that of Earth, could be within the host star’s habitable zone, they said.

The findings, published in The Astronomical Journal, are based on data from NASA Kepler spacecraft’s second mission, K2, and other data from the ground-based telescopes, including the Subaru Telescope in Hawaii and the Nordic Optical Telescope (NOT) in Spain.

The Japanese researchers found that K2-155d could potentially have liquid water on its surface based on 3D climate simulations. Hirano said: “In our simulations, the atmosphere and the composition of the planet were assumed to be Earth-like, and there’s no guarantee that this is the case.”

A key outcome from the current studies was that planets orbiting red dwarfs may have remarkably similar characteristics to planets orbiting solar-type stars.

“It’s important to note that the number of planets around red dwarfs is much smaller than the number around solar-type stars,” says Hirano. “Red dwarf systems, especially coolest red dwarfs, are just beginning to be investigated, so they are very exciting targets for future exoplanet research.”

While the radius gap of planets around solar-type stars has been reported previously, this is the first time that researchers have shown a similar gap in planets around red dwarfs. “This is a unique finding, and many theoretical astronomers are now investigating what causes this gap,” says Hirano.

He adds that the most likely explanation for the lack of large planets in the proximity of host stars is photoevaporation, which can strip away the envelope of the planetary atmosphere.

The researchers also investigated the relationship between planet radius and metallicity of the host star. “Large planets are only discovered around metal-rich stars,” Hirano says, “and what we found was consistent with our predictions. The few planets with a radius about three times that of Earth were found orbiting the most metal-rich red dwarfs.”

The studies were conducted as part of the KESPRINT collaboration, a group formed by the merger of KEST (Kepler Exoplanet Science Team) and ESPRINT (Equipo de Seguimiento de Planetas Rocosos Intepretando sus Transitos) in 2016.

With the planned launch of NASA’s Transiting Exoplanet Survey Satellite (TESS) in April 2018, Hirano is hopeful that even more planets will be discovered. “TESS is expected to find many candidate planets around bright stars closer to Earth,” he says. “This will greatly facilitate follow-up observations, including investigation of planetary atmospheres and determining the precise orbit of the planets,” he said.

Surface temperatures were plotted as a function of insolation flux (the amount of incoming stellar radiation) estimated at 1.67±0.38. When the insolation exceeds 1.5, a so-called runaway greenhouse effect occurs, signaling a cut-off point for life-friendly temperatures. If the insolation is under 1.5, the surface temperature is more likely to be moderate.

The results show a “radius gap”, or a dip in the number of stars with a radius between 1.5–2.0 times that of Earth.
