The object, officially designated (612533) 2002 XV93, belongs to a class of distant bodies known as trans-Neptunian objects, located in
What makes the discovery especially puzzling is that previous observations by the James Webb Space Telescope found no evidence that 2002 XV93 possesses surface deposits of nitrogen, methane, or carbon monoxide ice, the same volatile materials that generate Pluto’s atmosphere when warmed by sunlight. Temperatures on the object, estimated between 40 and 50 degrees above absolute zero, are also far too low for water ice or carbon dioxide ice to vaporize naturally.
The research, published in Nature Astronomy, therefore presents scientists with a genuine mystery. Existing models struggle to explain how such a small, cold object could sustain even a temporary atmosphere under these extreme conditions.
Researchers currently propose two leading scenarios, although neither fully explains the observations.
The first possibility is that a relatively recent impact from a comet-
The second hypothesis involves cryovolcanism, sometimes described as ice volcanism. Instead of molten rock, underground reservoirs of frozen volatile materials could occasionally erupt, replenishing the atmosphere from beneath the surface. Scientists do not yet know what internal energy source could power such activity on a body this small and cold, leaving the mechanism unresolved.
As the researchers explained,
“This discovery suggests that the traditional idea that global dense atmospheres form only around larger planets must be revised,” said Arimatsu’s team in their research paper.
That statement reflects how significantly this observation could reshape current thinking about atmospheric formation in the outer Solar System." msn
Allow me to add a 3rd "scenario" to the list for (612533) 2002 XV93: That is that it is young, only a few thousand years old, created as is, for a reason these men do not yet understand. Through faith we understand that the worlds were framed by the word of God.... Hebrews 11:3
