Alien Life Search Update: NASA Could Soon Locate Extraterrestrials With New Telescope

• The James Webb Space Telescope (JWST), which will go online in 2021 replacing the Hubble Telescope, will be the most sophisticated space telescope ever made. The JWST will be able to observe high redshift objects that are too old and too distant for the Hubble and other earlier instruments to observe. It promises to see deeper into time, and with much greater clarity, than any space-based or terrestrial optical telescope on Earth.

• One of the JWST’s major goals is observing some of the most distant events and objects in the universe such as the formation of the first galaxies, the formation of stars and planets, and direct imaging of exoplanets and novas. The JWST will be able to see 0.3 billion years after the Big Bang to when visible light itself was beginning to form. It will accurately measure the content of water, carbon dioxide and other components in the atmosphere of an exoplanet hundreds of light years away and will tell scientists more about the size and distance of these exoplanets are from their host suns. By measuring the chemical make-up of a planet, scientists will be able to see if it can host life.

• “Even if we never find other life in our Solar System, we might still detect it on any one of thousands of known exoplanets,” Cathal O’Connor, researcher and center manager at the University of Melbourne, said. “The ancient question ‘Are we alone?’ has graduated from being a philosophical musing to a testable hypothesis. We should be prepared for an answer.”

 

When the astonishing James Webb Space Telescope (JWST) sees first light in 2021, the world of science as we know it will never be the same again.

The most sophisticated space telescope ever made promises to see deeper into time, and with much greater clarity, than any space-based or terrestrial optical telescope on Earth. Some of the more starry-eyed fantasize JWST might even glimpse alien spacecraft hovering over their home planet.

Aliens May Discover Us Very Soon, Here’s Why

by Lorraine Lorenzo                  March 19, 2019                     (ibtimes.com)

• Clara Sousa-Silva, a quantum astrochemist, said during a segment in BBC’s online presentation “Ideas”: “We have been sending (television and radio) signals for the past 100 years, and those signals have gone into space and traveled at the speed of light and by now have reached hundreds of stars and hundreds of planets around them” There is a big chance that these aliens now know a lot about human origins, culture and history thanks to all the “material” that we’ve been sending them for years. “If there was an alien civilization then they would have heard the first BBC broadcasts… and have a rough idea of how our humanity works,” said Sousa-Silva.

• Sousa-Silva also said that some prominent scientists actually think that humans are sharing too much to the galaxy, especially since we know nothing about them. “Aliens may not be very kind so we shouldn’t be giving them our position.”

• But even without these television and radio signals, the Earth has a biosphere that basically gives any alien civilization an idea as to what type of species thrive in it. Aliens would be able to use a powerful prism to filter the white lights of our galaxy and separate the colors of the rainbow to determine our position in the universe. The shadows would tell them that this is indeed a lively planet filled with vast oceans and organic life forms.

• By the same principle of using radio signals to find earth, the scientist also believes that we can use alien biospheres to determine if there are extraterrestrials that actually exist in the universe. “At MIT, I develop the tools that try to decipher these potential alien biospheres. Those tools are how I will be listening in to alien messages. Until then I will try to find signs of life from signals aliens didn’t even mean to create,” Sousa-Silva said.

 

If you think that watching your favorite sitcom on Netflix or cable TV is just limited to entertainment, think again. We are also unknowingly sending vast signals to the universe and pretty much letting any possible aliens out in space know how to find us.

In fact, we’ve been sending out so many radio signals for the past 100 years that even if we turn off all satellites today, extraterrestrials from outer space will still be able to find us, Clara Sousa-Silva, a quantum astrochemist, said during a segment in BBC’s “Ideas.”

“We have been sending signals for the past 100 years and those signals have gone into space and traveled at the speed of light and by now have reached hundreds of stars and hundreds of planets around them,” Sousa-Silva, who is doing her post-doctorate degree in MIT and is a Ph.D. holder from the University College London, said.

The astrochemist said that the signals are now strong enough to be detected should there be alien civilizations out in the universe. Aside from this, there is also a big chance that these aliens now know a lot about human origins, culture and history thanks to all the “material” that we’ve been sending them for years.

“If there was an alien civilization then they would have heard the first BBC broadcasts and now they would have seen many, many years of Coronation Street and have a rough idea of how our humanity works,” she said.

Sousa-Silva also said that some prominent scientists actually think that it’s silly how humans are sharing too much to the galaxy especially since we know nothing about them.

“Aliens may not be very kind so we shouldn’t be giving them our position.”

Advanced Extraterrestrials as an Approximation to God

by Abraham Loeb                  January 26, 2019                      (scientificamerican.com)

• The excitement of the scientific enterprise is all about expanding our current knowledge of the universe a little at a time. Learning all at once of the knowledge of an alien civilization with billions of years of scientific and technological exploration would be a shock to the system, and would be difficult to reconcile. As science fiction writer Arthur C. Clarke stated: “Any sufficiently advanced technology is indistinguishable from magic.” Put another way, members of such a civilization would appear to us as a pretty good approximation to God.

• A device of advanced alien technology to us, would be like a smart phone to an early human caveman. This could be similar to our mainstream scientist’s reaction to the recent visitor to our solar system, the elongated rocky object known as ‘Oumuamua’. Oumuamua showed six peculiar properties but was nevertheless interpreted as a mere rock. One may wonder whether we are able to recognize technologies that were not developed by us.

• Scientists have considered whether life itself was seeded on Earth by an alien civilization in a process called “directed panspermia.” We can begin to wrap our heads around seeds of life brought to the Earth in the form of microbes, or perhaps a 3-D printer that produced these seeds out of the raw materials on Earth. Our imagination of what aliens might do may improve once we too are able to produce synthetic life in the laboratory.

• If life was seeded artificially on Earth, one may wonder whether the seeders are checking on the outcome. Are they disappointed and have given up on us? The experiment may have failed, or we are simply irresponsible and too slow to mature. Perhaps if we knew that someone is looking over our shoulders, we would do better.

• Our civilization is highly vulnerable to annihilation by self-inflicted wounds, such as nuclear wars or climate change, as well as external threats such as asteroid impacts or evolution of the sun. It would be not be prudent to keep all our eggs in one basket. We should venture into space and seed objects beyond the Earth with life as we know it, thus reducing the risk of complete destruction and securing the longevity of things we care about.

 

Despite the impression one gets from textbooks, our current knowledge of the universe represents a small island in a vast ocean of ignorance. The scientific enterprise is all about expanding the landmass of this island. And it is fun to engage in the activity of gaining knowledge; knowing everything in advance would have been much more boring. Still, it would be shocking to learn all at once of the discoveries of an alien civilization that’s been doing scientific and technological exploration for billions of years, in contrast to our mere few centuries. The eminent science fiction writer Arthur C. Clarke codified this idea in the third of his three laws : “Any sufficiently advanced technology is indistinguishable from magic.” Put another way, members of such a civilization would appear to us as a pretty good approximation to God.

Meeting a piece of advanced technological equipment developed by an extraterrestrial intelligence might resemble an imaginary encounter of ancient cave people with a modern cell phone. At first, they would interpret it as a shiny rock, not recognizing it as a communication device. The same thing might have happened in reaction to the first detection of an interstellar visitor to the solar system, ‘Oumuamua, which showed six peculiar properties but was nevertheless interpreted as a rock by mainstream astronomers.

Because it would likely be relatively small, most advanced equipment could only be recognized in the darkness of space when it comes close enough to our nearest lamppost, the sun. We can search for technological “keys” under this lamppost, but most of them will stay unnoticed if they pass far away. More fundamentally, one may wonder whether we are able to recognize technologies that were not already developed by us. After all, these technologies might feature subtle purposes—like the cell phone communication signals that a cave person would miss.

Is there something we might be missing already here and now?
