Was alien know-how found? Scientists review meteor fragments’ origin

July 15, 2023 Audrey

In 2014, a meteor crashed into the Earth and fragments scattered across the Pacific’s ocean flooring. Afterward Harvard astrophysicist Avi Loeb and his group went to the web page, which is around Papua New Guinea to recover the fragments, in accordance to United states Nowadays.

They recovered 50 fragments, which “they say is unmatched to any present alloys in our photo voltaic system,” for every United states of america Today. The fragments were being introduced to the Harvard College Observatory where by they ended up examined.

A question continues to be for the researchers: Was the meteor a merchandise of character or was it designed by aliens? Further exploration could shed mild.

Although Loeb recovered tiny fragments, he thinks it is doable he can obtain a more substantial piece. “We hope to come across a major piece of this object that survived the affect simply because then we can notify if it’s a rock or technological gadget,” Loeb explained to CBS News.

Loeb has spent a long time finding out the meteor. He and his group utilised details about the velocity of the meteor and comparisons to other meteors to postulate that it arrived from outdoors the solar procedure. A Division of Defense letter later verified this and Loeb started out to plan an expedition to get better it, for every NBC 10.

The U.S. federal government explained to Loeb the 6.2 mile radius wherever the meteor may well have landed, according to CBS News.

The expedition charge $1.5 million, The Guardian reported. Loeb and his crew had to figure out how to locate and extract an object found on the ocean floor, which was 1.7 kilometers (about one particular mile) below sea level. A ship with a magnetic sled was utilized to look for for and accumulate the fragments.

The fragments’ composition was noteworthy. “It has product strength that is more durable than all area rock that have been observed ahead of, and catalogued by NASA,” Loeb instructed CBS News. “… The point that it was created of products harder than even iron meteorites, and moving faster than 95% of all stars in the vicinity of the sun, suggested perhaps it could be a spacecraft from one more civilization or some technological gadget.”

The meteor in problem entered the Earth’s ambiance on Jan. 8, 2014 and was later learned in 2019, per Room.com. It’s regarded “the initial regarded visitor from interstellar area.” Scientists Loeb and Amir Siraj reportedly prompt the frequency of objects from interstellar area checking out Earth “could imply that the seeds of existence that had sprouted on our earth in the earlier 3.5 billion yrs may perhaps have arrive from a further star method.”

Loeb has previously stated he suspects there is extraterrestrial lifestyle.

“But if I experienced to guess, I would say not only that we are not by yourself, but that there ended up lots of technological civilisations before us that arrived at larger heights,” Loeb instructed UnHerd’s

Harvard professor Avi Loeb finds fragments in ocean that may perhaps be alien

An astrophysicist at Harvard University thinks he could have found evidence of extraterrestrial everyday living not by researching the vast evening sky, but by combing the base of the Pacific Ocean.

Past thirty day period, a crew aboard a boat referred to as the Silver Star embarked on an expedition to Papua New Guinea with the mission of recovering fragments from a mysterious meteor that experienced crashed into Earth in 2014.

Throughout the two-7 days excursion, the group scoured around 100 miles of ocean mattress ahead of recovering 50 little spheres composed of a metallic substance they say is unmatched to any present alloys in our solar program.

The spheres — which are so miniscule that they involve a microscope to see — have to have additional testing to determine regardless of whether they’re pure or technological in nature. Depending on the conclusions, the objects could be the initial time that humanity has identified stable evidence of interstellar beings.

In other text, aliens.

“Our results open up a new frontier in astronomy of learning what lies outside the photo voltaic procedure as a result of microscopes instead than telescopes, stated Avi Loeb, a professor and astrophysicist at Harvard University, who led the expedition as its main scientist.

The hunt for an interstellar meteor yields astonishing conclusions

The fragments the workforce uncovered are believed to be from a basketball-sized meteorite that in 2014 slammed into the Earth’s ambiance and into the western Pacific Ocean.

Originating from exterior the photo voltaic system, the meteor moved at a speed two situations faster than just about all of the stars in the vicinity of the sunlight, Loeb stated. Though also smaller to be seen by telescopes via its reflection of daylight, its collision with Earth produced a brilliant fireball recorded by U.S. govt sensors, Loeb included.

Loeb in 2019 discovered the meteor’s interstellar origin in a paper he co-wrote with Harvard undergraduate university student Amir Siraj. A few many years afterwards, U.S. Area Command even more verified in a 2022 letter to NASA that the object — deemed interstellar meteor, IM1 — came from another photo voltaic procedure.

The $1.5 million expedition that Loeb led was to get well the fragments remaining above from the explosion on the ground of the Pacific Ocean at its crash web page close to Manus Island in Papua New Guinea. Among June 14-28, the crew searched above 108 miles of the ocean ground by combing it with a sled complete of magnets connected to their boat.

Loeb mentioned it took times to get the magnetic sled on the ocean ground and a several more days immediately after that to comprehend just what the crew collected together the predicted path of the meteor — about 53 miles off the coastline of Manus Island.

“As we scooped the magnets, the most abundant substance hooked up to them was a black powder of volcanic ash,” he wrote

Harvard professor Avi Loeb believes he’s identified fragments of alien technology

CAMBRIDGE – Harvard professor Avi Loeb believes he may well have found fragments of alien technologies from a meteor that landed in the waters off of Papua, New Guinea in 2014.

Loeb and his staff just introduced the products back to Harvard for investigation. The U.S. Space Command verified with nearly around certainty, 99.999%, that the product arrived from an additional solar technique. The authorities gave Loeb a 10 km (6.2 mile) radius of where it may possibly have landed.

“That is where the fireball took position, and the government detected it from the Department of Defense. It can be a really significant spot, the dimensions of Boston, so we required to pin it down,” reported Loeb. “We figured the length of the fireball dependent off the time delay concerning the arrival of blast wave, the increase of explosion, and the gentle that arrived quickly.”

Their calculations permitted them to chart the possible path of the meteor. Individuals calculations happened to carve a route ideal by way of the same projected 10 km variety that arrived from the U.S. government. Loeb and his crew took a boat identified as the Silver Star out to the location. The ship took many passes alongside and about the meteor’s projected route. Scientists combed the ocean ground by attaching a sled entire of magnets to their boat.

“We observed ten spherules. These are just about best spheres, or metallic marbles. When you look at them as a result of a microscope, they search extremely distinct from the qualifications,” discussed Loeb, “They have hues of gold, blue, brown, and some of them resemble a miniature of the Earth.”

An examination of the composition confirmed that the spherules are built of 84% iron, 8% silicon, 4% magnesium, and 2% titanium, moreover trace things. They are sub-millimeter in dimension. The crew identified 50 of them in complete.

Harvard professor Avi Loeb believes these fragments may well be alien technology from a meteor that landed in the waters off of Papua New Guinea in 2014.

“It has materials power that is tougher than all house rock that ended up found just before, and catalogued by NASA,” included Loeb, “We calculated its speed outdoors the photo voltaic method. It was 60 km for every 2nd, faster than 95% of all stars in the vicinity of the solar. The simple fact that it was made of supplies tougher than even iron meteorites, and going quicker than 95% of all stars in the vicinity of the sunlight, advised likely it could be a spacecraft from a further civilization or some technological gadget.”

He likens the problem to any of the Voyager spacecrafts released by NASA.

“They will exit the photo voltaic system in 10,000 yrs. Just think about them colliding with one more world much away a billion years from now. They would seem as a meteor of a composition relocating more quickly than usual,” spelled out Loeb.

The exploration and investigation is just starting at Harvard. Loeb is

There should be far more evidence of alien technological innovation than alien biology across the Milky Way

The Drake equation is a single of the most popular equations in astronomy. It has been endlessly debated due to the fact it was 1st posited in 1961 by Frank Drake, but so considerably has served as an powerful baseline for discussion about how significantly everyday living may well be distribute throughout the galaxy. However, all equations can be improved, and a staff of astrobiologists and astronomers believe they have discovered a way to make improvements to this a person.

The equation itself was centered all-around the research for radio alerts. On the other hand, its formulation would suggest that it is additional very likely to see what are now generally termed “biosignatures” alternatively than technological kinds. For case in point, astronomers could obtain methane in a planet’s environment, which is a obvious indicator of lifetime, even if that world hasn’t designed any sophisticated intelligence nonetheless.

That look for for biosignatures was not attainable when Drake at first wrote the equation—but it is now. As such, it may well be time to modify some of the things in the first equation to reflect scientists’ new research abilities far better. A person way to do that is to break up the equation into two independent types, reflecting the lookup for biosignatures and technosignatures respectively.

Biosignatures, captured in the new framework by the term N(bio), would probable build much extra typically than technosignatures, captured in the new framework as N(tech). Logically that would end result from the reality that the range of planets that go on to develop a technologically state-of-the-art civilization is substantially significantly less than the overall selection of planets that form everyday living in the to start with spot. Following all, it took Earth all around 4 billion several years immediately after its first spark of everyday living to acquire an clever civilization.

But that will not account for a essential characteristic of technology—while it could have to originate from a earth with a biosphere, it certainly will not have to continue to be there. This noticeably impacts yet another issue in the Drake equation—L or the length of time that a sign is detectable. Dr. Jason Wright of Penn State University, the very first author of the new paper revealed in The Astrophysical Journal Letters, and his co-authors position out that four things point to technologies being probably extended-lived than biology.

Initial, as would be apparent to anyone who is a admirer of science fiction, engineering can lengthy outlive the biology that designed it. In fact, in some scenarios, the technology by itself can demolish the biosphere that established it. But it would nonetheless be detectable, even at a length, long soon after the lifeforms that had established it had died off. And it could do so on the get of hundreds of thousands or even billions of several years,

Sorry folks: ‘Alien’ signal from Proxima Centauri was likely just a broken computer on Earth

October 28, 2021 Audrey

A strange radio signal once thought to be a possible sign of alien intelligence in a nearby star system was likely created by a broken piece of human technology, according to new research.

On April 29, 2019, astronomers detected a signal beaming toward Earth, it seemed, from Proxima Centauri — the nearest star system to our sun (at about 4.2 light-years away) and home to at least one potentially habitable planet. Because the signal fell into a narrow band of 982 MHz radio waves that are rarely made by human aircraft or satellites, researchers interpreted it as a possible sign of alien technology.

However, the signal — which lasted for about five hours — never reappeared during subsequent scans of Proxima Centauri. The reason, according to two new studies published Oct. 25 in the journal Nature Astronomy, is likely because the signal wasn’t coming from Proxima Centauri at all.

To put it in Halloween-y terms: The call was coming from inside the solar system.

“It is human-made radio interference from some technology, probably on the surface of the Earth,” Sofia Sheikh, an astronomer at the University of California, Berkeley, and a co-author of both papers, told Nature.com.

In the first of the two new studies, Sheikh and her colleagues describe the signal — dubbed BLC1 — in detail. Astronomers picked up the five-hour-long flurry of radio waves with the Parkes Murriyang radio telescope in southeastern Australia during a 26-hour-long survey of Proxima Centauri. The survey was part of an ongoing $100 million alien-hunting program called Breakthrough Listen, which uses telescopes around the world to listen for possible extraterrestrial transmissions.

The telescope recorded more than 4 million radio signals from the vicinity of Proxima Centauri during that observation window, but only BLC1 struck astronomers as unusual, both for its lengthy duration and its peculiar wavelength. The team quickly ruled out interference from satellites or other human aircraft.

After the signal failed to reappear in subsequent observations of the star, however, the researchers took a closer look at their initial data. This time, they found that their automated sorting program had previously overlooked several signals that looked very similar to BLC1 but emitted at different frequencies.

In the second of the two new Nature papers, the researchers concluded that BLC1 and those “lookalike” signals were components of the same radio source; and that radio source was likely something on the surface of Earth, somewhere within a few hundred miles of the Parkes Murriyang telescope. That the signal appeared only during that five-hour observation of Proxima Centauri is probably just a coincidence, the team said.

Because the signal never reappeared, it’s possible that it was coming from a piece of malfunctioning electronic equipment that either got shut down or was being repaired, Sheikh told Nature. The range of frequencies within the signal was
