New findings on 'potentially hostile alien threat' hurtling through solar system leave NASA shocked

A peculiar object that has defied NASA's expectations has been identified in space, which has been labelled as an 'interstellar visitor'.

Once again, the James Webb Space Telescope (JWST) has done its job in making more groundbreaking space-related discoveries.

From laying its lens on its first ever exoplanet, to theories about humans living on our blue planet inside a black hole, the Hubble Telescope's successor is doing its job in finding out more about our universe.

Now, it has used its Infrared vision and its Near-Infrared Spectrograph instrument (NIRspec) to observe a comet named 3I/ATLAS.

It was discovered on 1 July by the ATLAS (Asteroid Terrestrial-impact Last Alert System) survey telescope, with experts at first believing it could have been an unidentified alien object.

Professor Avi Loeb of Harvard University even said that if it was alien, it could be 'potentially hostile'.

Well, while it turns out that the comet is very unlikely to be alien, it remains mysterious as NASA continue to study its movements and make discoveries.

It is the third-ever object making its way through our solar system that is said to have come from around another star. The previous two were discovered in 2017 and 2019, being named 1I/'Oumuamua and 2I/Borisov.

In observing the object, details such as its size, physical properties, and chemical makeup will become more clear, as a preprint paper has outlined why studying the comet is so key to understanding our universe.

Astronomers found that the object can be compared to what we know about conditions around the sun 4.6 billion years ago, when planets, asteroids, and comets were forming.

Essentially, when comets approach the sun, they are heated up and frozen materials in them are transformed into gases, resulting in something called 'outgassing', which gives them the iconic tail and halo that we associate with comets.

At the moment, 3I/ATLAS is outgassing as it reaches out sun, with the JWST and NIRSpec finding that carbon dioxide, water, water ice, carbon dioxide, and carbonyl sulfide, which is known for its grim smell, were being emitted.

The comet gave off the highest ratio of carbon dioxide to water ever observed too, which could mean that its core is rich in the former.

It would mean that its ices were exposed to higher levels of radiation than objects in our solar system are, with experts suggesting explanations on why the comet may have a high CO2 content.

They say that it could have been formed in a site known as the 'carbon dioxide ice line' in the swirling cloud of matter, or a 'protoplanetary disk', which made its way around its star.

The low levels of water in its coma also suggest that 3I/ATLAS may inhibit heat as its icy core is penetrated.

These new findings add to what is already known by scientists, including the previous discovery that the comet may be around three billion years older than our solar system.

Due to the object's steep trajectory, it was suggested that it comes from the Milky Way's 'thick disk' of stars', which is an ancient part of our galaxy which has been around far longer than the 'thin disk', where the sun was formed.

There's still more to uncover though - take it away, JWST.
