Interstellar comet 3I/ATLAS just hit its closest point to the Sun—hidden behind solar glare—and astronomers are freaking out over 8 bizarre anomalies that scream “not natural.” 😱 Harvard’s Avi Loeb warns: This could be an alien mothership dropping probes our way RIGHT NOW.

The mysterious interstellar visitor passing through our solar system has reached the sun, and what happens next will reveal if it’s an ordinary comet or a spacecraft.

As the massive object dubbed 3I/ATLAS makes its closest approach to our sun on Wednesday, many scientists believe it will begin to break up like a normal comet does under extreme heat.

However, if 3I/ATLAS remains intact and maneuvers away from the sun, it would be a sign of extraterrestrial intelligence, just like manmade spacecraft use rocket engines to veer away from objects in the solar system.

Wednesday’s critical milestone is called the perihelion, with the object moving approximately 126million miles away from the sun, which also marks the halfway point of 3I/ATLAS’ journey through our solar system.

Harvard physicist Avi Loeb called today’s move towards the sun ‘the acid test of 3I/ATLAS‘.

An ordinary space rock that is close to the sun would fracture into smaller fragments that evaporate under the power of the sun and create an even bigger plume of cosmic dust.

If it’s something else we can’t explain, Loeb said 3I/ATLAS might suddenly change direction, turn on lights, give off extra heat, or launch small probes toward planets like Earth or Venus.

There’s one problem, however, as we can’t actually see what’s happening near the sun today due to solar glare.

At the exact time scientists on Earth should be examining this cosmic turning point, 3I/ATLAS will be so close to the sun that every telescope will be blinded.

Loeb, who has maintained that 3I/ATLAS could be an artificially constructed craft since July, noted that the interstellar visitor’s course toward this solar blind spot could have been intentional.

‘We cannot observe 3I/ATLAS from Earth at this opportune time, which raises the question of whether its trajectory was fine-tuned by extraterrestrial intelligence?’ Loeb wrote in a blog post.

The professor added that scientists will need months of observations to see how 3I/ATLAS reacted to reaching its perihelion with the sun.

Currently, the object is unusually heavy, weighing approximately 33billion tons, has an oddly flat shape like a pancake, and has a surface covered in nickel.

Nickel is often used by Earth spacecraft to protect against the extreme heat of the vessel’s rocket engines.

In nature, nickel is typically found alongside iron, and space rocks normally have larger deposits of iron in these mixtures.

However, scientists have found the complete opposite in 3I/ATLAS, with the object showing little to no iron at all in its chemical makeup, which Loeb said was another sign of it being artificially constructed.

Despite the growing discussion that 3I/ATLAS could be an alien mothership conducting a hidden maneuver around the sun, most studies on the object have concluded that it’s merely a strange comet from a completely foreign part of the galaxy.

Researchers have noted that 3I/ATLAS has a tail of gas and dust, just like icy comets we see all the time.

Its strange chemical composition, which has been spewing plumes of carbon dioxide gas, has been attributed to the comet’s formation within a distant solar system in a thicker part of the Milky Way galaxy’s disk, where older stars are found.

Unlike comets that have formed in our solar system, which release clouds of water vapor into space, this distant solar system is believed to be rich in carbon dioxide ice, creating a unique comet that humans have never seen before.

Once 3I/ATLAS clears this solar blind spot, its next major milestone will come on November 3, when it passes within 58million miles of Venus.

That same week, the object is projected to come into view of Europe’s Juice spacecraft.

Scientists will be looking for any odd behavior as it approaches the planet, including changes in the visitor’s course and speed after leaving the sun.

On December 19, 3I/ATLAS is expected to reach it closest point to Earth, roughly 165million miles away, and Loeb has warned that this could be the point where an extraterrestrial craft launches probes to study our world.

‘For a spacecraft, perihelion is the optimal time for either acceleration or deceleration by an impulse from an engine, thanks to the gravitational assist from the sun,’ Loeb explained.

‘This is also true of a mothership releasing mini-probes that maneuver towards the planets.’
