A mysterious crater on Pluto<\/strong> may not be the result of an ancient impact but rather the collapsed caldera of a massive icy supervolcano<\/strong> that erupted just a few million years ago. A Recent studies based on NASA\u2019s New Horizons<\/strong> mission data reveal a geologically active world, suggesting that beneath Pluto\u2019s frozen crust may lie a reservoir of liquid water capable of fueling these extraordinary eruptions.<\/p>\n

A Supervolcano Unlike Any Other In The Solar System<\/p>\n

When the New Horizons<\/a><\/strong> spacecraft flew past Pluto in 2015, it captured images that challenged our understanding of this distant dwarf planet. Among the features spotted was Kiladze<\/strong>, a depression once classified as an impact crater. However, new research<\/a> led by planetary scientist Al Emran<\/strong> of the Jet Propulsion Laboratory indicates that Kiladze may be more like \u201cYellowstone Caldera in Wyoming,\u201d except instead of molten rock, it expelled cryomagma<\/strong>\u2014a mixture of water, ice, and ammonia.<\/p>\n

Kiladze\u2019s size and structure raised questions almost immediately. It measures roughly 27 miles (44 kilometers) across and plunges nearly 2 miles (3 kilometers) deep\u2014far deeper than an impact crater of that size should be. \u201cThe crater was too deep,\u201d Emran explained, noting that Pluto\u2019s geological activity would normally fill such depressions over time. Instead, its unusual depth and the absence of a typical central peak strongly point to a volcanic origin.<\/p>\n

Evidence Hidden In Pluto\u2019s Ice<\/p>\n

Surrounding the crater, scientists detected water ice<\/strong> enriched with traces of ammonia<\/strong>, a compound not seen elsewhere on Pluto. This discovery is critical because ammonia lowers the freezing point of water, potentially allowing subsurface liquid pockets to persist for millions of years. \u201cAmmonia<\/a> may be what allows the frigid ice to flow,\u201d Emran noted, adding that tectonic pressure could have driven this icy material upward, culminating in one or more explosive events.<\/p>\n

Researchers estimate that Kiladze\u2019s eruption could have released as much as 240 cubic miles (1,000 cubic kilometers)<\/strong> of cryomagma across the surrounding terrain. In some places, water ice appears to stretch for more than 60 miles (100 kilometers) from the crater, and scientists believe the actual dispersal could be far greater\u2014possibly extending for a thousand kilometers in finer, undetected deposits.<\/p>\n

The presence of ammonia also provides a potential timeline. Pure ammonia would not survive long under Pluto\u2019s harsh conditions because solar wind and cosmic radiation gradually destroy it. Its lingering signature implies that Kiladze\u2019s most recent eruption occurred within the past three million years<\/strong>, a blink of an eye in geological terms.<\/p>\n

What Pluto\u2019s Hidden Ocean Might Reveal<\/p>\n

The idea of a subsurface ocean<\/strong> on Pluto has been debated for years, but Kiladze\u2019s apparent cryovolcanic history has revived this possibility. Volcanic activity requires a heat source, and the evidence of such recent eruptions suggests that Pluto\u2019s interior may still be warm enough to keep water from freezing entirely.<\/p>\n

\u201cEven a centimeter or two of this organic smog would mask the water ice spectral signature we observe,\u201d said Dale Cruikshank, a planetary scientist at the University of Central Florida and a co-author of the study. Since this haze layer has not yet buried the water ice near Kiladze, the eruption must have been recent enough to expose it.<\/p>\n

If Pluto<\/a> can retain heat for billions of years, perhaps from radioactive elements in its core, then it might harbor isolated liquid water pockets\u2014or even a global ocean\u2014beneath its icy crust. <\/p>\n

This hidden ocean<\/a> could be the engine behind Pluto\u2019s surprising geological vitality and may hold clues to conditions that could support exotic forms of chemistry or even life. \u201cIf Kiladze erupted as recently as 3 million years ago, it would indeed suggest that Pluto\u2019s interior may still retain some residual warmth today,\u201d Emran explained.<\/p>\n","protected":false},"excerpt":{"rendered":"A mysterious crater on Pluto may not be the result of an ancient impact but rather the collapsed…\n","protected":false},"author":3,"featured_media":124266,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[24],"tags":[159,783,67,132,68],"class_list":{"0":"post-124265","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-science","9":"tag-space","10":"tag-united-states","11":"tag-unitedstates","12":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/114983236197027245","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/124265","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=124265"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/124265\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/124266"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=124265"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=124265"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=124265"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
