NASA's deep space probe 'New Horizons' has discovered five big things about the little-understood Pluto. What are they?

A new study suggests that the icy dwarf planet Pluto actually started out hot, formed quickly and had a subsurface ocean early in its history.

Named for the maiden snatching, shadow dwelling god of the underworld, small but mighty planet Pluto moves into Aquarius for the first time in two and a half centuries on March 23, 2023.

Light from Pluto’s moon Charon illuminated the dwarf planet’s farside offering clues about how nitrogen cycles between its surface and its atmosphere.
