Interstellar object 3I/ATLAS unexpectedly brightened up even before it was officially observed. NASA's TESS spotted it in May, two months before Atlas. Within a month, its brightness shot up five times. Scientists say this is not common with comets. Could this be another anomaly?

What is 3I/ATLAS up to? NASA detects sinister anomaly in interstellar object in precovery data

3I/ATLAS is the third interstellar object, and a scientist has claimed it is not a natural space rock, but an alien spaceship sent by advanced beings. He has listed several reasons for it that are based on his observations, and those made by NASA 

LISTED! All the clues that point to 3I/ATLAS being an alien tech, not a comet

Interstellar object 3I/Atlas might be accompanied by a probe moving ahead of it, which can take a detour and enter Mars. Harvard scientist Avi Loeb has claimed that this strange object is not moving alone through our solar system. He says "a precursor mini-probe" can reach Mars when the "mothership" comes at its closest distance to "the complete path of Mars around the Sun." This will happen sometime in October, when the object will be only 2.7 million kilometres from the red planet. Loeb says this itself is a "remarkable fine-tuning" of the path, since, on October 3, it will be 29 million kilometres from Mars. This means that during its entire sojourn with the planet, it will reduce this distance considerably. He cites this extreme cut down in distance as another clue that points to 3I/Atlas not being a natural space rock. In fact, the way it is moving shows that something sinister is at play. How else do you explain closing the distance by such a huge margin?&nbsp;<h2>A secret invisible probe is travelling with 3I/Atlas, Loeb says</h2>This brings us to his more intriguing hypothesis that there is another body travelling with 3I/Atlas that we cannot see from Earth. The interstellar object is turning towards Mars to plant a probe on the planet. Loeb has calculated that if such a probe exists, then it is travelling ahead of the main body. But it is not moving in a straight line, and is on a sideways trajectory which would take it to Mars. If this is true, then this precursor probe can intercept Mars on October 3, 2025 or during the week before it. "If 3I/ATLAS is a technological object, this short MOID (Minimum Orbit Intersection Distance) makes it easy for a precursor mini-probe to reach Mars," he wrote. So why haven't we seen it yet? Webb, Hubble, and no other telescopes have spotted a partner with 3I/Atlas. Loeb explains that this is because it is extremely tiny. He wrote in his blog that this object is likely smaller than a hundred meters, and near-Earth telescopes cannot detect the reflection of sunlight from such precursor objects.Also Read: <a href="https://www.wionews.com/trending/wake-up-call-for-humanity-scientist-wants-3i-atlas-to-be-alien-spaceship-here-s-why-1756095787834">'Wake-up call for humanity’: Scientist wants 3I/ATLAS to be alien spaceship — Here’s why</a>Also Read: <a href="https://www.wionews.com/trending/harvard-scientist-calls-on-world-leaders-to-prepare-common-plan-on-alien-attack-1755064546960">3I/ATLAS and its 'intent': Harvard scientist calls on world leaders to prepare for an alien attack</a>&nbsp;&nbsp;Loeb has a way to detect this secret friend that 3I/Atlas has.

Is 3I/ATLAS not alone? Scientist says an invisible ‘probe’ racing ahead of it could strike Mars

Interstellar object 3I/ATLAS can help humans with interstellar travel. Harvard scientist Avi Loeb has suggested that if we intercept the alien "mothership", then we can gain access to valuable data and information on interstellar travel. This would cut down not only on time spent on researching how to leave the solar system, but also save us billions and trillions of dollars. He argues in a blog post that the visitor from the outer world can help humans journey through space, something that seems almost impossible right now. 3I/ATLAS is currently thought to be a comet, but Loeb thinks it could be an alien probe sent by an intelligent civilisation living in another part of the universe. If this turns out to be true, he thinks humans should try to learn more about it, as it would offer a multitude of benefits scientifically. However, he has also raised fears that aliens could be coming to attack Earth.

NASA’s SPHEREx space observatory has noticed a cloud of carbon dioxide (CO2) around 3I/ATLAS, the interstellar object racing towards the inner solar system. The observations were made between August 8–12, and Harvard scientist Avi Loeb has an interesting theory about it. He has been claiming that this object is not natural and has been sent by extraterrestrial beings to probe Earth and other planets. He wrote in a blog post that SPHEREx noticed "a mass loss rate of about 70 kilograms per second" and "no water (H2O) cloud was detected." Loeb added that the NASA report shows a "lack of a bright water gas coma", which has confused scientists since 3I/ATLAS was "not too far outside the Solar system’s 'water ice line” at 2.5 AU" when the observatory made the observations. He admits that even though H2O is not present in gas form, "the reflected spectrum from the surface of 3I/ATLAS" showed a "mix of water and carbon dioxide ices combined with organics."Also Read: <a href="https://www.wionews.com/trending/wake-up-call-for-humanity-scientist-wants-3i-atlas-to-be-alien-spaceship-here-s-why-1756095787834">'Wake-up call for humanity’: Scientist wants 3I/ATLAS to be alien spaceship — Here’s why</a> Also Read: <a href="https://www.wionews.com/trending/harvard-scientist-calls-on-world-leaders-to-prepare-common-plan-on-alien-attack-1755064546960">3I/ATLAS and its 'intent': Harvard scientist calls on world leaders to prepare for an alien attack</a>&nbsp;<h2>NASA observatory data suggests 3I/ATLAS is extremely large</h2>He once again argued that the latest images by SPHEREx do not resolve the "dust coma" contention, and the sunlight scattered around it is compact and reflecting off the dust on it.

1-in-500 cosmic coincidence? Scientist says 3I/ATLAS could be millions of times bigger than 2I/Borisov, only if...

Harvard scientist Avi Loeb earnestly hopes that the interstellar alien object in the solar system turns out to be a spacecraft sent by extraterrestrial beings. This comes after his very open assertion, backed by evidence, that it is not a natural space rock or comet. He has said that almost everything about 3I/ATLAS points to it being an object designed by someone. Its trajectory, the light it released, and the lack of a tail are signs that it is not a naturally occurring cosmic body. Meanwhile, everyone else is refuting his claims, saying it is impossible that 3I/ATLAS is an alien spacecraft. But Loeb stands steadfast on his observations. In fact, he actually wishes that the interstellar object were an alien probe coming for Earth.

Are aliens coming to attack Earth with 3I/ATLAS? A Harvard scientist thinks it will be good news for Earth if the interstellar visitor turns out to be an alien spacecraft. He says encountering alien technology will change humanity forever. 

Harvard scientist Avi Loeb earnestly hopes that the interstellar alien object in the solar system turns out to be a spacecraft sent by extraterrestrial beings. This comes after his very open assertion, backed by evidence, that it is not a natural space rock or comet. He has said that almost everything about 3I/ATLAS points to it being an object designed by someone. Its trajectory, the light it released, and the lack of a tail are signs that it is not a naturally occurring cosmic body. Meanwhile, everyone else is refuting his claims, saying it is impossible that 3I/ATLAS is an alien spacecraft. But Loeb stands steadfast on his observations. In fact, he actually wishes that the interstellar object were an alien probe coming for Earth. In a new blog post, Loeb states that the "mothership" will be a wake-up call for humans busy fighting for land and resources on Earth. He has previously called for world leaders to join hands and work towards a common threat, which 3I/ATLAS could be.

'Wake-up call for humanity’: Scientist wants 3I/ATLAS to be alien spaceship — Here’s why

Where do interstellar objects come from? Scientists have revealed where Oumuamua, 2I/Borisov, and 3I/Atlas originated in space, and also their age. One of them is almost as old as Earth. Where are they headed?

Where did interstellar objects 1I/'Oumuamua, 2I/Borisov, and 3I/Atlas come from? And where are they going?

Harvard scientist Avi Loeb has claimed that the interstellar object 3I/ATLAS hurtling towards the inner solar system is an alien spaceship sent by an advanced civilisation. Other astronomers agree that it is a comet, but Loeb has proposed his alternate theory, one that has been dismissed by almost every other expert. This could have flagged humans as undeserving of a "high status in the class of intelligent civilisations within the Milky Way galaxy." Loeb has now claimed that the probe is something like a Turing Test for humanity. He says that anyone who dismisses the object as a space rock could have failed the test in the eyes of an extraterrestrial being. Interstellar object 3I/ATLAS is only the third visitor to our solar system from outer space.

Scientist claims mystery interstellar object is here to test human intelligence, and we have already failed. Here's why

A Pacific expedition is being planned by a prominent Harvard physicist to find what he believes to be an alien artefact which has fallen from space into the ocean.

Physicist Avi Loeb announced that an ocean expedition worth $1.5 million to Papua New Guinea is being organised by him in search of fragments of an object which crashed off the coast of the country's Manus Island in 2014.

The object was noticed by Loeb in 2019 and it was identified as the first ever discovered interstellar meteor, which means its origin lies outside our solar system.

As per Loeb, the interstellar origin of the meteor was confirmed to NASA by the Department of Defence’s space command in April 2022.

Loeb and his team also reached the conclusion that the meteor was tougher compared to all other 272 meteors listed in the Centre for Near Earth Object Studies catalogue of NASA.

“Intrigued by this conclusion, I established a team that designed a two-week expedition to search for the meteor fragments at a depth of 1.7km on the ocean floor. Analysing the composition of the fragments could allow us to determine whether the object is natural or artificial in origin,” wrote Loeb in a post on Medium.

“We have a boat. We have a dream team, including some of the most experienced and qualified professionals in ocean expeditions. We have complete design and manufacturing plans for the required sledge, magnets, collection nets and mass spectrometer,” he further stated.

As per Loeb, there is a possibility that the meteor is tough “because they are artificial in origin…launched a billion years ago from a distant technological civilisation.”

A ship with a magnetic sledge is expected to be used for the ocean expedition. The team will include seven sledge operations along with a scientific team.

“We will tow a sledge mounted with magnets, cameras and lights on the ocean floor inside of a 10km×10km search box. A number of sources have been used to narrow the search site to this relatively small search box,” wrote Loeb and his team.&nbsp;

Harvard physicist in search for ‘alien artefact’ that fell from space

Scientists have launched an undersea expedition to trace and collect the pieces of the first known&nbsp;interstellar object&nbsp;that hit Earth in 2014, reports Science Alert. The said object had crashed into the ocean just off the coast of Papua New Guinea.

Examples of Interstellar objects are asteroids,&nbsp;comets, or rogue planets that are not gravitationally bound to a star.

The data at the time revealed that the object was a meteorite. Dubbed CNEOS 2014-01-08, the object is believed to have measured about a half-meter wide, and its potentially interstellar origins were first recognised by then graduate student Amir Siraj and Harvard professor Avi Loeb.

The data they collected at the time indicated that it could be an interstellar object—the first known to hit Earth and the third ever recorded. &nbsp;The other two interstellar objects recorded are Oumuamua and Borisov.

Siraj and Loeb had concluded that CNEOS 2014-01-08 might be from beyond our Solar System due to its unusually high heliocentric velocity, meaning it was moving at speeds that suggest it may not be bound within the Sun's gravity.

However, the problem in 2014 was that the data used to measure the object's impact which would confirm whether it is an interstellar object came from a US Department of Defense spy satellite. As a result, the details of the object were carefully guarded.

Therefore, a paper by Siraj and Loeb has remained unpublished and not peer-reviewed.

But this year in March, US Space Force's Space Operations Command's chief scientist Joel Mozer reviewed the classified data and confirmed that the “velocity estimate reported to NASA&nbsp;is sufficiently accurate to indicate an interstellar trajectory”.

US Space Force lieutenant general&nbsp;John Shaw signed the letter confirming the interstellar object.

However, tracing the remnants of the meteorite is likely to throw up some challenges as it might burned up during its descent into Earth's atmosphere, likely leaving only fragments behind, scattered across the ocean floor.

Hence, the expedition team would be likely carrying a large magnet connected to a trawling ship to pick up the pieces.

Scientists to search ocean for interstellar object that hit Earth in 2014

A Harvard scientist wants to investigate a meteor that is said to be an alien technology and currently lying at the bottom of the Pacific Ocean.&nbsp;

Last week, a document released by the United States Space Command (USSC) stated that researchers discovered the first known interstellar meteor to ever hit Earth.&nbsp;

As per the document released by US Space Command, the officials noted that a meteor that made an impact on Earth on January 8, 2014, was an interstellar object.&nbsp;

The object, measuring just 1.5 feet across, is named CNEOS 2014-01-08. Researchers noted that it crash-landed along the northeast coast of Papua New Guinea.&nbsp;

In the latest development, Harvard astrophysicist Avi Loeb claimed that the object is apparently a piece of alien technology. "Our discovery of an interstellar meteor heralds a new research frontier," Loeb wrote in The Debrief.&nbsp;

"The fundamental question is whether any interstellar meteor might indicate a composition that is unambiguously artificial in origin. Better still, perhaps some technological components would survive the impact," he added.&nbsp;

Significantly, Professor Loeb spent decades studying astronomy and reportedly he is probing the possibility that life exists beyond Earth.&nbsp;

As reported by Daily Mail, he suggested that the object can be investigated by taking it out using a magnet in order to examine it. He added that retrieving the object could be an opportunity to fulfil a lifelong dream of getting his hands on alien technology.&nbsp;

"My dream is to press some buttons on a functional piece of equipment that was manufactured outside of Earth," Loeb also wrote.&nbsp;

The document released by USSC noted that the velocity and trajectory of the meteor suggested the space rock was apparently from deep space, meaning the extrasolar in origin.&nbsp;

The paper also mentioned that this discovery will help enable a new method for studying the composition of interstellar objects. The new method will be based on spectroscopy of their gaseous debris as they burn up in the Earth's atmosphere.&nbsp;

Presence of alien tech on Earth? Scientist wants to probe interstellar object 'lying in the Pacific Ocean'

The universe holds secrets we’re not completely programmed to understand. But humanity is always at the cusp of a breakthrough when it comes to knowledge accumulation and the new 3D map of our solar system proves just that!

Ever thought about what lies at the edge of our very own solar system? Turns out, it’s a blob!&nbsp;

What's the edge of our solar system?

The edge of our system is where cosmic forces collide. On one edge lies solar wind comprising charged particles that emanate from the Sun. On the other side lie winds of space, laden with radiation absorbed from billions of stars situated nearby.

Solar winds or flares cause blackouts on Earth every once in a while but otherwise do an excellent job of protecting the planet from space radiation.

According to LiveScience, the solar winds wrap our solar system in a protective layer, preventing 70 per cent of space radiation from entering our system. Earth’s own magnetic shield does the job of protecting us from the leftover radiation.

This protective layer is called the heliosphere and its edge is called heliopause. At this junction lies a physical border where our solar system ends and the outside space begins.&nbsp;

What does the 3D map reveal?

On June 10, a new study in the Astrophysical Journal revealed the first 3D map of the heliosphere ever.

To achieve this, scientists used data collected by NASA’s Interstellar Boundary Explorer satellite over 10 years. Using this, they tracked particles in solar winds that travel from the Sun to the edge of solar system and back.

Based on this, they calculated how far the solar wind was able to go before being blown back by interstellar radiation. This allowed the researchers to map the edges of our solar system.

The map shows how the heliosphere isn’t really a sphere, but a squishy looking blob-like entity with inconsistent borders. In one end the border is thick while it is extremely thin on the other side.

This is because the Sun is also locked in orbit at the centre of the Milky Way, akin to Earth’s orbit around Sun. In one direction, the Sun has more scope of pushing out solar winds that counter interstellar radiation, explaining the inconsistency of the border.

In a first, new 3D map reveals details about the edge of our solar system

Astronomers have detected&nbsp;how many interstellar objects may be visiting our solar system, in a recent study.

The research conducted by Cornell University shows interstellar objects (ISOs) passing through the solar system can be directly observed by Earth-based telescopes and potentially explored at close range by spacecraft.

The aim of the study was to find&nbsp;additional ISOs and planning missions to intercept or rendezvous with these bodies will greatly benefit from the knowledge of their likely orbits and arrival rates.

&nbsp;

The feasibility of reaching interstellar objects passing through the solar system has been assessed with specific missions to the interstellar objects 1I/’Oumuamua and 2I/Borisov,&nbsp;&nbsp;the first InterStellar Objects (ISOs) discovered passing through the solar system.

Observations made with the NASA/ESA Hubble Space Telescope and others show that the object is moving faster than predicted while leaving the Solar System.

Researchers assume that venting material from its surface due to solar heating is responsible for this behaviour. This outgassing can be seen in this artist’s impression as a subtle cloud being ejected from the side of the object facing the Sun. As outgassing is a behaviour typical for comets, the team thinks that `Oumuamua’s previous classification as an interstellar asteroid has to be corrected.

Such missions are feasible with more massive spacecraft (100 kg or larger) using existing rockets and technologies either if they can be initiated around the time of perihelion passage, for example, by a Comet Interceptor type mission or by using a combination of planetary flybys and solar Oberth manoeuvres (rocket accelerations at high speed close to the Sun) to overtake the ISO as it retreats from the Sun.

Marshall Eubanks, the lead author of the study said&nbsp;"[J]ust by proving that they exist, it has had a profound impact, creating a field of study almost from nothing (a field that funding authorities are just beginning to recognize).''

He added, ''Interstellar Objects provide us with the opportunity to study, and in the future literally touch, exobodies decades before the earliest possible missions to even the nearest stars, such as Proxima Centauri."

As per the study, led by researchers from the Initiative for Interstellar Studies (i4is), roughly seven ISOs enter our Solar System every year and follow predictable orbits while they visit the Earth.

The study of 'Oumuamua in October of 2017 was not only was this an object that had formed in another star system, but its arrival and detection implied a large population of such objects.

The detection of 2I/Borisov in 2019 confirmed that ISOs enter our Solar System on a pretty regular basis.

Asteroid surveys may have a streak limit, a limit on the acceptance of fast-moving small objects, in order to reduce confusion with terrestrial satellites.

Interstellar objects likely formed very far from the solar system in both time and space; their direct exploration will constrain the formation and history of small bodies, situating them within the dynamical assembly and chemical evolution of the Galaxy. The velocities of many of these objects in the solar system will make their detection and their exploration by spacecraft challenging, but not impossible with present and near-future technology.

If the number of density estimates based on the discovery of 1I/’Oumuamua are even approximately correct, there should be a number of 1I-type interstellar objects in the solar system at any one time.

Even a fast flyby of an ISO passing through the solar system would be scientifically very rewarding, especially if the object can be subjected to the analysis of impact signatures.

Unfortunately, 2I-type interstellar comets appear to be much rarer, which a much smaller infall rate, and will probably be a once in a decade phenomena.
