3I, Interstellar comet and ATLAS

Interstellar comet 3I/ATLAS transforms into a giant 'cosmic rainbow' in trippy new telescope image
New photos, including a striking technicolor timelapse, show off the newly discovered interstellar object 3I/ATLAS as it shoots toward us through the solar system.

Given 3I/ATLAS' highly eccentric orbit, this will be its one and only visit to our solar system, as its trajectory does not loop back around the sun. That's why astronomers around the world are using a wide variety of telescopes to observe the comet during its brief visit, before it returns to interstellar space.
Our Best View Yet of Interstellar Comet 3I/ATLAS
The Gemini North telescope in Hawaii recently snapped a close-up of the comet that's captured the world’s attention.
7 Big Mysteries about Interstellar Object 3I/ATLAS
Scientists are racing to learn as much as possible about the interstellar comet 3I/ATLAS before it fades from view forever
Gemini North Telescope Spots Interstellar Comet 3I/ATLAS Racing Through Solar System
Comet 3I/ATLAS is expected to make its closest pass by the Sun on Oct. 30, when it will fly 130 million miles inside the orbit of Mars. It comes closest to Earth in December, when it is 170 million miles away. Because of its odd orbit, it's never coming back.
Gemini north observes comet 3I/ATLAS, the third-known interstellar object
Interstellar objects are visitors from solar systems beyond our own, and the third ever such object, known as 3I/ATLAS, has just been discovered. Using the Gemini North telescope, astronomers have captured 3I/ATLAS as it makes its temporary passage through our cosmic neighborhood.
'Interstellar visitor' 3I/ATLAS could be the oldest comet ever seen — and could grow a spectacular tail later this year
New simulations have narrowed down where the newly discovered interstellar comet 3I/ATLAS likely came from, revealing it could be more than 3 billion years older than the solar system.
What we know so far about 3I/ATLAS, the interstellar visitor
New findings about interstellar comet 3I/ATLAS reveal its surprising size, possible thick disk origin, and what makes it unlike any other ISO
Interstellar Comet 3I/ATLAS Spotted In New Pictures Captured From Hawai'i
3I/ATLAS is only the third object which has been confirmed to have originated outside our solar system after 1I/Oumuamua (2017) and 2I/Borisov (2019). It was discovered by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) on July 1 and is expected to make its closest approach to the Sun on October 30.
Interstellar visitor 3I/ATLAS might be the oldest comet ever seen
Astronomers tracking an interstellar object flying through the solar system think it comes from a star at least 8 billion years old, almost twice the age of our sun
