A new study found a small, icy world past Pluto. This world has a thin atmosphere, perhaps from volcanoes or a comet.

This tiny object is only about 300 miles wide. It is the smallest known object with its own global atmosphere.

This discovery gives new information about cold, far-away objects. Scientists say this finding is amazing, but it needs more checks.

Scientists saw the object dim a star in 2024 with telescopes. Finding an atmosphere on such a small world was truly surprising.

This small world orbits very far from the sun, past Pluto. Its atmosphere is extremely thin, perhaps methane or nitrogen.
