Experts say that if an object like this were on a collision course with Earth, it could pose unprecedented challenges for planetary defence systems. Here are seven reasons why its size and speed make it unlike any threat humanity has faced before:

7 reasons why 3I/ATLAS’s size and speed makes it a unique threat to Earth

The discovery of 3I/ATLAS, the third confirmed interstellar object to pass through our Solar System, has sent ripples through the global space defence community. 

7 reasons why 3I/ATLAS could challenge current asteroid deflection plans

In Hinduism, the seven celestial bodies such as Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn are revered as Navagrahas, each representing divine forces that influence human life, destiny, and spiritual energy according to Vedic astrology.

The Manhattan-sized interstellar object 3I/ATLAS has baffled scientists with its unusual trajectory, massive size, and strange acceleration. Some researchers, including Harvard astrophysicist Avi Loeb, suggest it could be a technologically advanced alien probe.

7 reason why scientists believe 3I/ATLAS comet could be an alien mothership?

As of Oct 3, the seven-member Expedition 73 crew includes Commander Sergey Ryzhikov, cosmonauts Alexey Zubritsky and Oleg Platonov, NASA astronauts Jonny Kim, Zena Cardman, Mike Fincke, and JAXA’s Kimiya Yui.

As the mysterious interstellar comet 3I/ATLAS speeds through our Solar System, social media has been buzzing with theories, some scientific, others… not so much. 

5 countries where alien invasion rumours about 3I/ATLAS went viral

As interstellar comet 3I/ATLAS makes its way through the Solar System, astronomers across the globe are racing to observe and document its behaviour. 

Top 8 countries using ground telescopes to study 3I/ATLAS

Home to some of the world’s most powerful telescopes, Chile’s Atacama Desert also offers crystal-clear skies for naked-eye astronomy. 

10 countries best positioned to view 3I/ATLAS with the naked eye

As 3I/ATLAS approaches the Sun, it will heat up, causing its icy nucleus to release gas and dust, forming a glowing coma and a visible tail.

A high-speed impact would eject massive amounts of dust and debris into the atmosphere. This could block sunlight for weeks or months, disrupting agriculture and potentially causing “impact winters.” Temperature drops, acid rain, and blocked sunlight could affect ecosystems globally.

'Brace for impact': What would happen if 3I/ATLAS comet actually hits Earth?

3I/ATLAS was identified in 2024 by the ATLAS survey in Hawaii. Preliminary data suggests it has a hyperbolic orbit, confirming its interstellar origin.

Stories of alien invasions, secret government knowledge, and hidden messages are inherently more exciting than orbital data and telescopic observations. 

'Psychology of doomsday': Why people believe alien invasion rumours around every space event like 3I/ATLAS?

Speculation about alien origins intensified because 3I/ATLAS, like ‘Oumuamua, follows a hyperbolic orbit, meaning it isn’t bound to our Sun.

By directly sampling this frontier, Voyager proved the firewall isn’t a blockade, but rather a semi-permeable filter, more like a cosmic sponge than a wall.

Why 50,000°C 'Firewall' isn’t a wall but a filter? Here's what NASA's Voyager data says..

As Voyager crossed the heliopause, its detectors recorded a sharp drop in incoming cosmic rays from outside, showing the firewall’s effectiveness as a natural filter.

How Voyager's 'Firewall' blocks cosmic radiation before it reaches Earth?

Voyager detected sudden jumps in plasma density and magnetic pressure as it passed the firewall, showing how the Sun’s magnetic bubble interacts with space beyond.

Why Voyager's 'Firewall' works like Earth’s Magnetosphere on a larger scale

The firewall separates the Sun’s solar wind bubble (heliosphere) from the interstellar medium. Scientists see it as a border checkpoint, marking the point where solar control ends.

Why scientists call Voyager’s 'Firewall' the solar system’s border checkpoint?

The firewall filters and redistributes cosmic radiation. Without it, the inner Solar System would face much higher exposure to harmful interstellar particles.

Why 'Firewall' protects our solar system instead of burning it? Understanding Voyager’s Data

The firewall confirmed the existence of a boundary layer that separates the Solar System from interstellar space. This region marks the first point where our Sun’s influence fades.

'Why firewall isn’t fire at 50,000°C': Voyager’s most misunderstood discovery

Declassified US Navy UFO footage (Tic Tac, Go Fast, Gimbal) shows craft defying conventional physics. These visuals echoed Lazar’s descriptions decades earlier, though without direct proof.

How NASA and physicists accidentally supported Bob Lazar’s UFO claims

This theory explains why UFOs in reported sightings appear to make instant turns or move at extreme speeds without inertia affecting them. By bending space rather than moving through it, they avoid conventional physics limits.

Inside the firewall, solar particles dominate. Outside, interstellar particles take over. Voyager showed how solar influence diminishes sharply at this edge.

The firewall acts as a filter, deflecting many high-energy cosmic rays. This shield helps reduce radiation exposure within the solar system, playing a role in Earth’s long-term habitability.
