In our nearby stellar neighborhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only NASA's Hubble Space Telescope could identify that this meal is taking place.
The period known as "cosmic noon," which took place roughly 2 to 3 billion years after the Big Bang, was characterized by the rapid formation of new stars and planetary systems. Naturally, objects dated to this period are ...
Comet 3I/ATLAS is the third ISO ever detected. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station on 1 July 2025. It's traveling through the inner solar system at about 220,000 km/h and ...
The earliest images of 3I/ATLAS, newly uncovered by Michigan State University, reveal how the interstellar object evolved as it traveled through our solar system—and how other distant solar systems might be different from ...
Interstellar objects like 3I/ATLAS that have been captured in planet-forming disks around young stars could become the seeds of giant planets, bypassing a hurdle that theoretical models have previously been unable to explain.
The eyes of every astronomer widened this year when an interstellar traveler was discovered in our solar system.
Astronomers and students working together through a unique educational initiative have obtained a striking new image of the growing tail of interstellar Comet 3I/ATLAS. The observations reveal a prominent tail and glowing ...
Southwest Research Institute (SwRI) has completed a mission study detailing how a proposed spacecraft could fly by an interstellar comet, providing remarkable insights into the properties of bodies originating beyond our ...
The recent discovery of the third known interstellar object (ISO), 3I/ATLAS, has brought about another round of debate on whether these objects could potentially be technological in origin. Everything from random YouTube ...
All (or at least most) astronomical eyes are on 3I/ATLAS, our most recent interstellar visitor that was discovered in early July. Given its relatively short observational window in our solar system, and especially its impending ...
