Among these celestial visitors — the interstellar object 3I/ATLAS, along with C/2025 A6 (Lemmon) and C/2025 R2 (SWAN) — not ...

Comet 3I/ATLAS was discovered on July 1, 2025, by the NASA-funded ATLAS telescope in Rio Hurtado, Chile and was quickly confirmed to be just the third interstellar visitor to our solar system, after ...

Far beyond Neptune, at the outer rim of our Solar System, astronomers have spotted what resembles a hidden “structure” or “band” of small worlds. The Kuiper Belt is a vast ring of icy bodies beyond ...

Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, the enormous, donut-shaped region of icy objects beyond the orbit of Neptune. This latest “inner kernel” was identified by ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

Astronomers report that Chiron, an icy world between Saturn and Uranus, is building a fresh set of rings. The timing matters, because the system seems to be evolving. A Brazil-led team is tracking it.

Material around Chiron, a small icy world in the far reaches of the solar system, may be taking shape into a ring system of its own. The rare event is unfolding in real time, giving astronomers a ...

Ernest Opik, an Estonian astronomer based at the Astronomical Observatory in Tartu from 1921-1944, commenced research on the frequencies and speeds of meteors and comets in the 1920s. In 1932, Opik ...

It was early January 2025 when a faint light spot was observed at the Mt. Lemmon Observatory in Arizona. Follow-up observations revealed that the object was a comet visiting from the outer edge of the ...
