A team of astronomers from Taiwan has uncovered promising evidence suggesting the existence of Planet 9, a hypothesized ...

(Web Desk) - Astronomers have discovered a new world circling the outer edges of our solar system. Researchers using the Subaru Telescope, located in Hawaii, spotted a small, distant object called ...

Japan's Subaru Telescope in Hawaii detected a faint, icy body. Now named 2023 KQ14, or Ammonite, it lies well beyond Pluto.

A newly found icy object, Ammonite, may be a 4-billion-year-old fossil from the Solar System’s edge—and it’s casting doubt on the Planet Nine theory.

For reference, Pluto’s average distance from the Sun is about 40 AU, so 2023 KQ14 is quite distant. At 23.4 billion miles (37 ...

Researchers use the Subaru Telescope in Hawaii to find a small object on the outer edge of the Solar System. Nicknamed ...

Two decades ago, astronomers proposed this was due to the gravitational pull of a world up to 10 times larger than Earth, naming it Planet Nine and kicking off a debate that has rumbled since.

Japanese astronomers have discovered a potential dwarf planet, nicknamed Ammonite, orbiting the Sun far beyond Neptune, challenging the existence of the theorized Planet Nine.

In the cold, distant reaches of the Solar System, far beyond Pluto, astronomers have just identified what could be a new dwarf planet. It's called 2017 OF 201, a rock that appears to be some 700 ...

Over the past decade, researchers have been puzzling through Pluto’s mysteries. Meanwhile, the New Horizons probe heads for interstellar space.
