An Exomoon is a natural satellite that exists around a planet outside our solar system. Astronomers are pretty surebut they still have to make a final discovery (and some even think which they " To call moon moons ").
Researchers at the University of Bern describe this new Exomoon candidate in a study to be published in the Astrophysical Journal and available as a pre-print on arXiv. Sodium gas, which was detected near the giant planet WASP-49b, suggests that its orbit may contain a volcanic exomoon similar to.
"The neutral sodium gas is so far away from the planet that it is unlikely to be emitted by just a planetary wind," says Apurva Oza, a postdoctoral fellow at the University of Bern in a press release. The Exomoon "would be a dangerous volcanic world with a molten surface of lava … a place where Jedi would die, which Anakin Skywalker is dangerously known for."
In fact, Anakin Skywalker did not die on the molten surface of Mustafar, but here Kenobi confirmed that the conversion of the fallen Jedi to a dark-hearted Sith Lord was complete.
To be clear, the researchers did not directly observe a moon around the gas giant WASP-49b. Instead, they found evidence that such a volcanic exomoon could be in the form of sodium gas and the right conditions for the survival of such a sullen satellite.
Oza's work shows that a heavily volcanic exomoon spits sodium and potassium into space. Jupiter's moon Io was the best solar system equivalent for such a phenomenon, causing the research team to call the signal they see around WASP-49b "Exo-Io".
Oza admits, however, that a large ring of ionized gas surrounding WASP-49b could also explain the presence of the proven sodium gas.
"We need to find more clues," he says.
If the volcano is exomoon, it might be even stranger than Mustafar because it orbits a huge, hot gas giant planet orbiting its host star in less than three days. Such conditions would certainly be too intense even for a Jedi Master, but perhaps the comingwill surprise us with more lava lightsaber combat scenes.
