NASA Debunks Alien Origin Claims of Interstellar Comet 3I/ATLAS

Interstellar objects like 3I/ATLAS, Oumuamua, and Borisov are the most common objects in the Milky Way galaxy, with estimates suggesting there are trillions of them, but they are difficult to detect due to their small size and dark nature. Upcoming surveys like the Vera C. Rubin Observatory's LSST are expected to significantly increase detection rates, providing opportunities to study the galaxy's chemical evolution and potentially retrieve samples from distant planetary systems.

Scientists Reclassify 'Oumuamua' as an 'Exo-Pluto' Fragment

Scientists now believe 'Oumuamua is a fragment of an ancient Pluto-like body ejected from the solar system, composed mainly of nitrogen ice, and not a typical comet, providing new insights into the chaotic early history of our solar system.

Scientists classify 'Oumuamua' as a new 'exo-Pluto' object

Research suggests that 'Oumuamua, the first known interstellar visitor, may be a fragment of an icy exoplanet similar to Pluto, composed mainly of nitrogen ice, and represents a new class of celestial objects called 'exo-Plutos,' indicating such objects might be more common than previously thought.

Top 5 Solar System Mysteries That Still Baffle Scientists

Despite extensive research, several mysteries in our solar system remain unsolved, including the formation of the asteroid belt, Uranus' extreme axial tilt, the Sun's corona temperature anomaly, Saturn's hexagonal storm, and the interstellar object 'Oumuamua, each posing significant questions about planetary and solar phenomena.

Origins and Destinations of Interstellar Objects 1I/'Oumuamua, 2I/Borisov, and 3I/Atlas

Scientists have traced the origins of three interstellar objects—Oumuamua, Borisov, and Atlas—finding they come from different regions of the Milky Way and are of varying ages, with Atlas being the oldest. Oumuamua is currently leaving our solar system, Borisov is in the constellation Ara, and Atlas is headed towards the inner solar system, possibly as a comet or even an alien spaceship. These objects provide insights into other star systems and the galaxy's history.

Tracking the Journey of Interstellar Objects 1I/'Oumuamua, 2I/Borisov, and 3I/Atlas

Astronomers have tracked the trajectories of three interstellar objects—'Oumuamua, Borisov, and Atlas—revealing they originated from different regions and ages within the Milky Way, providing insights into the diversity of planetary systems and galactic dynamics. These objects serve as natural probes into other star systems, and future observations and missions are expected to expand our understanding of interstellar material and its origins.

Hubble's New View of Interstellar Comet 3I/ATLAS Sparks Hope and Concern

Harvard astronomer Avi Loeb suggests that the approaching interstellar object 31/ATLAS could be engineered rather than natural, citing its unusual brightness and glow, and warns it could either save or threaten humanity. Loeb emphasizes the need for caution and further examination of interstellar objects entering our solar system.

Scientists Debate Alien Origins of Interstellar Meteors and Objects

Astronomers believe small interstellar objects frequently pass through our solar system and hit Earth, but detecting these tiny, fast-moving bodies remains challenging. Recent discoveries of interstellar objects like 'Oumuamua and Borisov support the idea of a continuous influx of alien debris, yet unambiguous detection of interstellar meteors in Earth's atmosphere has so far eluded scientists. Increasing sky surveillance could help capture these cosmic visitors and deepen our understanding of other star systems.

Interstellar Object Influenced Planetary Orbits

A new theory suggests that an interstellar object, with a mass between 2 to 50 times that of Jupiter, may have passed through the Solar System and influenced the orbits of the planets. This theory, proposed by scientists led by Garett Brown from the University of Toronto, posits that such a visitor could explain the eccentricities of the gas giants' orbits better than current models. The study indicates a 1 in 100 chance that this event shaped the planetary orbits we observe today, offering a plausible alternative to existing theories of planetary migration.

NASA Sheds Light on Mysterious Dark Comets and Their Impact on Earth

New research has identified seven additional 'dark comets,' doubling the known number to 14 and categorizing them into two distinct groups based on orbit and size. These objects, which exhibit both asteroid and comet-like behaviors, may have played a role in delivering the building blocks of life to Earth. The study highlights the enigmatic nature of dark comets and their potential origins from larger bodies in the asteroid belt.

"Capturing 'Oumuamua: The Quest for Interstellar Visitors"

A proposal has been published for a mission to send a spacecraft to study future interstellar objects passing through our Solar System, acknowledging that it will be a long time before we visit other star systems. The paper explores the practicality of catching up with an interstellar object, considering the most suitable instruments for such a job, and estimates that the preparation of such a spacecraft and placing it in orbit would cost less than a billion dollars.
