SOFIA Space Observatory Studying Jupiter Moon Europa for Life Signs

• Dr. Amanda Hendrix, co-lead of the NASA Roadmaps to Oceans World Group, believes that studying the oceans of other worlds is the key to finding alien life beyond the Earth – albeit microbial life. “We need to understand whether these oceans are habitable and if so, whether these oceans actually host life,” says Dr. Hendrix.

• In 2017, NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) flying observatory discovered that Jupiter’s moon Europa’s icy surface expelled water plumes containing approximately the amount of water in an Olympic-sized swimming pool. In 2018, the NASA Galileo probe flew through a giant plume of water vapor erupting from Europa. These plumes blast debris a hundred miles high, according to the spacecraft’s data.

• Hendrix reasons that life on Europa will most likely be clustered around hydrothermal vents on its subterranean ocean floor in a watery world of perpetual darkness. What passes for warmth on Europa is largely derived from tidal “kneading” caused by the colossal gravitational forces created by its orbit around gas giant Jupiter, the solar system’s largest planet.

[Editor’s Note]   Mainstream scientists continue their long, drawn out process of pretending to seek alien life beyond Earth, in order to give the impression that smart people are doing their best but still cannot come up with anything beside a theory of microbial life in thermal plumes. Therefore, the public is reassured that we are the only intelligent life in the universe, reinforcing the Deep State delusion that the galaxy really isn’t teeming with intelligent civilizations, nor are government and private secret space programs interacting with extraterrestrial beings on a regular basis.

 

Humans have long pondered whether our world is unique in the universe in sustaining life. Scientists are increasingly confident “wet” worlds resembling Earth are the best place to start the search for alien life. And accordingly, US space agency NASA a craft to search for clues of early life on Jupiter’s moon Europa.

The NASA Galileo probe last year flew through a giant plume of water vapour erupting from Europa’s icy surface.

These plumes blast debris a hundred miles high, according to a fresh analysis of the spacecraft’s data.

The discovery has cemented the growing scientific consensus Jupiter’s moon, one of four first spotted by the Italian astronomer Galileo Galilei in 1610, is the most promising place in the solar system to hunt for alien life.

Now NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) spacecraft has revealed tantalising clues to understanding Europa’s environment and its subsurface ocean.

Such erupting water plumes contain approximately the amount of water in an Olympic-sized swimming pool.
Although’s SOFIA’s 2017 observations did not directly detect the plume, it did establish an upper limit on how much water could be in the plumes.

This upper limit is pivotal to ongoing NASA analyses into the contents and origins of the plumes, which will help reveal if Europa has the ingredients to support life.

Any life found on Jupiter’s moon Europa will have to be made of sturdy stuff.
Europa’s surface temperature never rises above -160C (-256F).

And what passes for warmth on Europa is largely derived from tidal “kneading” caused by the colossal gravitational forces created by its orbit around gas giant Jupiter, the solar system’s largest planet.

Alien Lifeforms Will Be Discovered Within 20 Years, British Scientist Predicts

by Jasper Hamill                         November 19, 2018                         (metro.co.uk)

• Dr. David L Clements, a top astrophysicist at Imperial University (Imperial College London) as recently published a paper claiming that alien life will be discovered within 20 years. “…[N]ew observational insights and other developments mean that signs of life elsewhere might realistically be uncovered in the next decade or two,” says Clements.

• In his study, Dr. Clements discussed the Fermi Paradox, saying that an alien space-faring civilization, “…should thus already be here, and yet they are not.” “This can be used as an argument against the existence of intelligent extraterrestrials, but our own existence is proof that intelligent life can and does arise in the Galaxy. This is the central puzzle of the Fermi Paradox.”

• Dr. Clements’ paper goes on to suggest that life is likely to be found in oceans locked beneath the frozen surface of moons or planets. In our own solar system, one of the most likely homes for alien life is Europa, a moon of Jupiter which is believed to be hiding a gigantic body of water beneath its icy crust. “We are left with the rather chilling prospect that the galaxy may be filled with life, but that any intelligence within it is locked away beneath impenetrable ice barriers, unable to communicate with, or even comprehend the existence of, the universe outside,” says Dr. Clements.

[Editor’s Note]  Perhaps the true error is in the assumption that alien beings should already be here, “yet they are not”. Oh, they’re here alright, and in a variety and numbers that will astound the intentionally uninformed citizens of planet Earth. They will reveal themselves when it serves their purpose. The question is, is the reason that they are here one that is negative or positive for the human race?

 

In a newly published paper, one of the nation’s top astrophysicists has claimed we will discover traces of alien life within 20 years. Dr David L Clements of Imperial University said that ‘detecting signs of life elsewhere has been so technically challenging as to seem almost impossible’ until very recently. ‘However, new observational insights and other developments mean that signs of life elsewhere might realistically be uncovered in the next decade or two,’ he continued.

In his study, Dr Clements discussed the Fermi Paradox, which is the contradiction between the high probability of life existing in the universe and the fact we haven’t managed to detect it. Theoretically, a ‘space-faring civilisation’ should be able to visit every single star in the galaxy in a timescale of between 50 and 100 million years – even if they travelled at velocities which were slower than the speed of light. ‘Aliens should thus already be here, and yet they are not,’ Dr Clements added. ‘This can be used as an argument against the existence of intelligent extraterrestrials, but our own existence is proof that intelligent life can and does arise in the Galaxy. ‘This is the central puzzle of the Fermi Paradox.’

His paper goes on to suggest that life is likely to be found in oceans locked beneath the frozen surface of moons or planets – which could have big implications for the development of a civilisation. In our own solar system, one of the most likely homes for alien life is Europa, a moon of Jupiter which is believed to be hiding a gigantic body of water beneath its icy crust. ‘We are left with the rather chilling prospect that the galaxy may be filled with life, but that any intelligence within it is locked away beneath impenetrable ice barriers, unable to communicate with, or even comprehend the existence of, the universe outside,’ the paper continued. ‘We know that species that live in water can evolve to a high level of intelligence – dolphins and octopuses are good examples. ‘However, A liquid environment may be a limiting factor in the development of technology.’

Jupiter’s Moon Europa Has Huge Shards of Ice That Could Stop Us Finding Aliens Who Live There

by Andrew Griffen                   October 8, 2018                    (independent.co.uk)

• Jupiter’s moon Europa is often held up as one of the most promising places to discover extraterrestrial life. It is relatively near and has huge seas of liquid water under its surface, which could provide a home to those aliens. However, in a new research paper, Dr Daniel Hobley, from Cardiff University’s School of Earth and Ocean Sciences describes how treacherous the surface of Europa is for landing spacecraft or probes.

• “The presence of sharp, blade-like structures towering to almost 15 metres high would make any potential landing mission to Europa extremely precarious. We hope that studies like ours will help the engineers to develop innovative ways of delivering landers safely on Europa’s surface so that we can find out even more about this fascinating place, and potentially look for signs of extra-terrestrial life,” said Dr Hobley.

• These massive shards of ices, or “penitentes”, are formed through a process known as sublimation. That turns ice into water vapor without melting into a liquid between the two, and leaves behind those blade-like formations that point right up into the sky. Europa has the right thermal conditions for this sublimation to occur, and the sun always shines at the same angle towards the surface. Penitentes between one and five metres tall do grow on Earth, but are restricted to extreme areas such as the Andes Mountains.

 

Towering blades of ice could get in the way of our search for alien life, scientists have warned.

Scientists hope to eventually land a spacecraft on that icy crust and drill down beneath it to see whatever is lurking in the oceans below.

But on that same alien surface are vast shards and daggers of snow that could destroy any craft that attempted to land there, scientists have warn. Reaching almost 15 metres tall, the blades of sharp ice could be a fatal barrier to any attempt to meet that extra-terrestrial life.

Any potential landing mission would have to navigate those “penitentes” before it could drop onto the surface.
