The Mini Pluto with an Impossible Atmosphere: The Discovery Driving Astronomers Crazy

Mini Pluto-like frozen dwarf planet with atmosphere and cryovolcanoes beyond Neptune in deep space.

https://www.myscrappydays.com/news.php?slug=mini-pluto-with-atmosphere-cryovolcanoesMini Pluto-like frozen dwarf planet with atmosphere and cryovolcanoes beyond Neptune in deep space.More than 60 billion kilometers away from the Sun, there’s a tiny frozen world that, technically, should be completely dead.No geology. No atmosphere. No movement.Just darkness, ice, and silence drifting through the outer edge of the Solar System.And yet… something up there is still breathing.Astronomers recently discovered that the distant trans-Neptunian object (612533) 2002 XV93 possesses a thin atmosphere despite being only about 500 kilometers wide. Compared to Pluto, it’s incredibly small. But somehow, against all expectations, this frozen object is still active.The strangest part?Scientists suspect that the atmosphere may be sustained by cryovolcanoes — icy volcanoes capable of ejecting frozen gases like methane and nitrogen into space.It sounds like science fiction written at 3 a.m. under neon lights. But it’s real astronomy.

Volcanoes have been shaping our planet for millions of years. However, Earth is not the only planet in the solar system that volcanoes have shaped. They are all over our solar system, and some are still active, emitting molten lava and even frozen water plumes. Here are five fascinating examples of active volcanoes in our own solar system, and why they matter.

Supervolcano eruption on Pluto hints at hidden ocean beneath the surface

That ice lava had to come from somewhere.

Scientists studying spacecraft data of an unusual crater near a bright, heart-shaped region on Pluto called Sputnik Planitia say they may have found a supervolcano that likely erupted just a few million years ago. That might sound like an incredibly long time ago, but cosmically speaking, it's pretty recent. For context, the solar system is more than 4.5 billion years old.  Instead of molten rock that blasts out of Earth's volcanoes, however, the 44-km-wide Kiladze crater appears to have spewed ice lava onto Pluto's surface in a process known as cryovolcanism. The process, which also unfolds on the moons of gas giants in our solar system and likely created other mystifying terrains on Pluto, is thought to have thrusted water from the world's hidden subsurface ocean onto its surface, reshaping it across millions of years. Volcanoes require some sort of heat source to blow up, so the recent activity on Pluto suggests there is more heat remaining in the dwarf planet's interior than previously thought.

Io has 266 Active Volcanic Hotspots Linked by a Global Magma Ocean

NASA's Juno spacecraft is giving scientists their first good look at Io's polar regions. The case for a magma ocean is getting stronger.

Jupiter’s Io stands apart from the Solar System’s other moons, with its numerous volcanoes and its surface dominated by lava flows. Io’s surface volcanism was confirmed in 1979 when the Voyager spacecraft imaged it, but its volcanic nature isn’t duplicated anywhere else in our system. Tidal heating is behind the moon’s eruptive nature, driven by Jupiter’s powerful gravity, and by resonance with other moons. But is there a magma ocean inside Io? A final answer to that question has been elusive, but new research supports the idea of a magma ocean.

Pluto has a supervolcano!

An Unusual Crater on Pluto Might be a Supervolcano

Recent research on images and data taken by New Horizons show what may be a super-cryo-volcano on Pluto's icy surface.

Pluto with a super-cryovolcano? Why not! All the elements are there, just not in the way we normally think of volcanoes. Plus, cryovolcanoes are the reason Pluto's surface looks the way it does.

A recent research paper explains why Pluto could be the home of the latest supervolcano discovery in the Solar System.
