1. Pluto's "Ice-erupting Volcano"
A few years ago, a New Horizon astronaut who passed close to the dwarf planet Pluto in our solar system discovered some mountains that looked like terrestrial volcanoes, but at some point Extreme cold water and snow were released from.
Scientists have named these mountains "ice volcanoes" (ice volcanoes).
Now, new research on these icy volcanoes has led experts to estimate that these icebergs were alive "only" 100 million years ago or less when they were melting ice.
If this is true then we have to change our information about Pluto's past and present because Pluto was considered to be extremely cold due to being 3.7 billion kilometers away from the Sun.
The majority of experts agreed that Pluto did not have too much heat inside, and not only outside, but also inside.
Mountains, like volcanoes next to ice, have been thought to have been in this state for at least a billion years, but new research suggests that this condition may be only 100 million years old or less.
One estimate is that Pluto may still be very hot internally today, causing snow and cold water to flow out of the mountains.
These things are currently in the form of assumptions that have made Pluto's "ice-splitting volcanoes" even more mysterious.
